I stopped telling people that I spent my July 4th holiday removing the ducts from the basement. The statement evoked a quizzical look. They pictured me shooing a quacking flock from the house. I did not want to agree with a colleague who replied, ‘Ah, you’re committed!’ because it feels like only the insane would remove a heating system from a house in Maine, even in summer.

My brother and his wife flew up from New York for a visit last weekend in a tiny plane that used only as much fuel as my Subaru. It was a short, cold and wet vacation for them. I said, earnestly, ‘you should come back in the summer; it’ll be warmer.’ James Prentice, one of the contractors working on this house added, ‘for both weeks or just one?’ I lit a fire in the wood stove on Saturday night to take off the edge.

James and John, “the guys,” will move the big cast-iron wood stove into the ‘ell’ so that I can finish sanding the flaking polyeurethane from the living room floor. Without the wood stove, I will be entirely committed. Nuts.

While I’ve been finishing floors and yanking old floor boards from the attic of the ‘ell’ and repairing the hole I cut in the hot water pipe to the kitchen sink, they have been rebuilding the porch roof and installing air sealant. The air sealant went in fine but for an expansion that pushed out a section of lathe and plaster above one of the bay windows, an easy repair. Already, the house feels calmer and quieter without the air tunnel that was rushing between the two floors.

What’s curious and unsurprising to me lately is how few encounters I have with green products, except when I specifically seek them out. There is no signage at the lumber yard in Brunswick or the one in Damariscotta about the FSC-certified wood that they stock in a separate barn, away from the meanderings of non-contractors like me. There is no signage at the hardware stores (big box or otherwise) about non-toxic alternatives to floor finishes…because they don’t stock them. (I have been looking for beeswax to go over the linseed oil that is now on these old pine floors. If I go to FW Horch in Brunswick, I know I will find non-toxic alternatives but for a pretty penny. Unwilling to forgo green floor finishes altogether, I did use a non-toxic German finish in one of the closets and a low-VOC finish in the front hallway. The hallway is the only space that will see a polyeurethane top coat, so I guess one could say I de-greened it.) I encounter no displays of air exchangers or solar panels. No fuel companies advertising biofuels, though the local fuel service companies all stock on-demand hot water heaters and energy-efficient heating appliances. There’s a sign for BioHeat on a lawn about 10 miles down the road. There’s a retail store in Topsham selling corn pellet stoves.

John, James and I rehash heating options, with these constraints: the chimneys cannot be used, the new oil tank in the basement should be used, the heating appliance will be in the conditioned space of the house. One of the solutions is a through-the-wall vented, standalone appliance running on biofuels. This is important stuff and it takes some research and hunting to put it together.

Steven Shapin reviewed David Edgerton’s “The Shock of the Old: Technology and Global History Since 1900” in The New Yorker, and wrote, “technological significance and technological novelty are rarely the same–indeed, a given technology’s grip on our awareness is often in inverse relationship to its significance in our lives…we are wrong to associate technology solely with invention, and that we should think of it, rather, as evolving through use.”

The general public, despite the “boom or bubble” of all things green, is likely far more aware of the Apple iPhone than biofuels. If only biofuels and non-toxic products were sexy, fun and insignificant. Then I might find them everywhere.

Real Companies Entering Renewable Energy

by Richard T. Stuebi

I reckon that relatively few readers have heard of the company called Preformed Line Products (NASDAQ: PLPC). I know I hadn’t, even though their headquarters is just a few miles from where I live in suburban Cleveland.

A couple of months ago, I came across a press release indicating that PLPC had entered the solar energy sector by acquiring Direct Power & Water of Albuquerque. I decided to investigate further.

PLPC is a real company, not some publicly-traded start-up venture. The company was formed in the late 1940’s, and has steadily grown to a worldwide operation based on core competencies in developing and manufacturing of high-performance cables and connectors for the electric utility and communications industries. PLPC net income in 2006 was $12 million on revenues of $217 million — certainly not anywhere near the size of a Fortune 500 corporation, but nevertheless a nice business.

The letter from the Chairman and CEO (Robert Ruhlman) in the company’s 2006 annual report provided some insight on the impetus for PLPC’s acquisition of Direct Power & Water:

“In addition to multiple opportunities in our traditional markets, there are exciting new opportunities in emerging technologies. One area we are exploring for growth potential is renewable energy. Wind and solar energy are becoming more economically feasible due to improved technologies, rising costs of traditional energy sources and increasing demand for energy independence. We believe PLP can play a significant role in these markets as these technologies develop.”

This kind of statement, and the subsequent follow-up action to make a real bet on solar energy, is exactly what the renewable energy sector needs a lot more of: the interest of mainstream corporate America, especially the small- and medium-sized manufacturing sector, seeing the opportunity to build a business in renewables — truly for profits and not just for PR purposes.

Cleantech or Status quo Jobs?

by Nick Bruse

One of the most exciting aspects of the cleantech/sustainability sector are the opportunities presented to create completely new industries over the coming years. Transforming the way we approach housing, feeding and powering our society. Whilst at the same time attempting to maintain the quality of life, and I emphasis ‘quality’ not gluttony, and improve the standard of life for the developing world.

As an optimist I believe that humanity can take on this challenge, with a realistic understanding that its going to take a lot of hard work, innovation and leadership. What frustrates me is when conservative governments stand up and expouse that by leaving our old industries behind we will force our economies to suffer and jobs to be lost.

This is the mantra that we have heard in Australia time and time again under the Howard Government. What i would like to hear in Australia is that with our high quality research institutions, and plethora of cleantech startups we are now putting our hand up to be a leader in clean technology.

So my next question is, how many jobs is the cleantech sector including the jobs that will be created through carbon emissions trading, for auditing and assessment, and how does this compare with and emission intensive industry like coal mining.

I hunted down some information on the Australian Coal Industries employment statistics and here’s what i found.

Around 30,000 people were employed at Australian black coal mines at the end of 2005. This represents a return to levels not previously seen since the mid 1990’s – the most recent peak being around 26,000 in 1996. Along with the decline in the number of underground mines, employment at underground mines declined significantly over the past decade – from around 11,000 in 1996 to just over 9,000 in 2005 – a drop of about 20 per cent. Employment in open-cut mines on the other hand increased from just under 15,000 to over 19,000 (30%) in the same period. 2006 statistics Australian Coal Association

Now I assuming that these figures don’t include all the jobs in processing and handling. Possibly another 20-50% the figure. Now at this point the data on cleantech jobs is fairly hard to find, as we are talking about multi-industry analysis, and new industries sectors like emissions trading. But i have found some stats from a Sustainable Energy Industries Report 2000

Total direct employment in the sustainable energy industry [in Australia] is in the order of 22,800 in 1999-2000 and 25,600 in 2000-2001. This represents an annual growth rate of 12%. The total employment effect of the sustainable energy industry on the economy is in the order of 64,000 in 1999-2000 and 72,000 in 2000-2001.

Now there is 6 years between these reports but i think we can assume that the sector in renewable energy has increased somewhat. Now theres not a huge amount of difference between these figures, So when the government talks about jobs what really is it talking about. My guess is that its talking not purely about economic losses from reducing the mining of carbon and our exports, but what its actually worried about is due to the nature of the way in which the coal mining industry differs from the renewables industry.

Centralised vs distributed. Fuel intensive vs Technology Intensive.

My gut feeling is that with coal mining being centralised around mines and distribution routes that means you make policy decisions on coal mining that you affect centralised populations of voters, all in one electorate. When you make decisions about the renewable energy industry you are actually talking about a broad range of technologies associated with many different services providers spread over a broad number of electorates.

Hence decisions on coal mining can flip an electorate to the opposition very quickly, whereas decisions to renewables have only until now had a marginal effect on individual electorates. Sentiment is changing substantially that the federal government can no longer hide behind this dynamic much longer. I don’t wish job losses on coal mining towns, but i do wish for the correct decisions to be made to not sell out the future of all Australians for short term political favour.

I’m interested in comments on this article, what’s the status in Europe, India, China or the United States. How do other issues of energy security and economic security bear out regarding job creation in these regions.

Blogroll Review: Soy, Dreams, Stealing

by Frank Ling

Renewable Warfare

When you think of biofuels, the military may be last place that comes of mind. But major defense contractor Honeywelll has announced plans to accelerate the development of military jet fuels from vegetable and algae.

Jim Fraser at the Energy Blog says:

“Fuel produced by the new process is expected to achieve 90 percent energy efficiency for maximum conversion of feed to fuel, reduced waste and reduced production costs.”

Now what about weapons made from recycled materials? 🙂


Speaking of planes, Boeing will debut its long awaited 787 Dreamliner this Sunday. Hank Green at EcoGeek says:

“The plane will use roughly twenty percent less fuel per mile than other plane in its class. Two innovations make this possible. First, it’s ultra-efficient turbo-fan jet engines. But while some other planes are using the turbo-fans, no one else is using carbon fiber like Boeing. More than 50% of the plane, in fact, the entire fuselage, is made of carbon fiber.”

Solar Thieves

Stealing manhole covers for iron is a problem in many countries. Now, the metals needed to make solar panels are under threat. With the rise is price of materials (copper, nickel, zinc, etc), the theft of these materials is becoming prevalent.

Tyler at Clean Break says:

“Junkyards are being raided, hydro and cable companies are seeing a rise in the theft of copper cabling, and homeowners with ornamental pieces on their lawns are seeing them disappear.”

At least no one is stealing the sun! 🙂

Not so very many moons ago, I was job hunting in the Washington, DC area. Inherently shy, job hunting has always filled me with dread. On this occasion, a divorce from a Hong Kong dynasty had added a deep layer of self-doubt. My mate at the time circled ads in the help-wanteds (perplexed that this action fanned my fears). I recall his humor, a humor that I did not share, when he drew a line around a posting for a receptionist-phlebotomist and acted out a mock dialogue in the imagined reception area: Fill out these papers and then I’ll prick your pinky. Hahaha…Hahaha!

More than a decade down the road, I reflect on this strange job combination and requests I have made of “the guys” working on this old house and their flexibility in finding solutions — despite some less-than-perfect circumstances. They are working on the roof over the front porch, creating a pitch to shed water and snow. They are reinforcing the frame, and they are adding to the cavity 2″ extruded foam and closed-cell spray foam to block air flow into the space between the first and second floors — all before before adding new underlayment, membrane and asphalt. (I did not choose the greener building materials of metal roofing, soy-based foam or FSC wood — additional costs that will need to go to the essentials of plumbing and heating.) A roofer had proposed replacing the existing old metal roofing with a membrane. The roofer would not replace or shore-up existing wood, some of which is rotten. The roofer would not have suggested creating a pitch. The roofer would not recommend or do air sealant.

As this project unfolds, it seems to me that successful adoption of new residential energy-efficient and green technologies will require contractors who are comfortable with complexity. A homeowner casting about for help in renovating a home (an old one in particular) does far better with a whole-house contractor — one who understands the interactions of the home’s systems.

And if the homeowner is a destructo-Shiva who might accidentally sever a copper pipe under the kitchen sink with a reciprocating saw the day before a holiday — necessitating the shut off of all the hot water to the house — a multi-tasking contractor is even more helpful.

When James and John are done with the roof, we will be moving ahead with replacing the copper mangle of plumbing with PEX (including the piping to the kitchen sink!). This new water supply system will, unlike the existing one, include many, functioning, shut off valves. Until then, it may be cold showers for me.

On this July 4th holiday, I’m grateful that I still have water.

Fuels from Wood and Waste not Food and Haste

By John Addison (7/3/07) Americans are screaming for lower gasoline prices. In São Paulo, Brazil, the price of gasoline is R$2.43/liter, ethanol is only R$1.48/liter, disclosed Brazil’s National Petroleum Agency. Brazil has reduced its petroleum dependency by 40% with sugarcane ethanol.

The United States and Brazil together produce about 90 percent of global fuel ethanol. In the United States the current benefits of ethanol are far behind Brazil.

“Thanks in large part to the Renewable Fuels Standard (RFS)—a legislative mandate for increased renewable fuels use that passed as part of the Energy Policy Act of 2005—the corn ethanol industry is expanding at an unprecedented rate in the United States. The 115 ethanol plants operating in April 2007 have the capacity to produce 5.75 billion gallons per year (BGY) of ethanol, and an estimated 86 plants under construction are expected to produce an additional 6.34 BGY of capacity within the next 18 months (RFA, 2007). The cumulative total capacity—more than 12 BGY by 2009—far exceeds the RFS blending mandate of 7.5 BGY by 2012, and has been the driving force behind skyrocketing corn prices in the last 12 months.” – World Resources Institute

In the United States, ethanol has reduced our petroleum dependency by about 5%. That amount is rapidly increasing. Many states require ethanol as an oxygenating agent in gasoline, replacing MTBE and tetraethyl lead. A growing number of states are requiring that gasoline be sold with a blend of 10% ethanol (E10).

There is a heated debate about whether ethanol helps the environment. If you live in Brazil, the answer is “yes.” In Brazil, ethanol is processed from sugarcane, which produces over eight times more energy than the fossil energy used in its production. In the United States, ethanol is currently produced from corn. Brazil can achieve yields of 2,500 gallons of ethanol per acre. The U.S.; 300 to 500 gallons per acre.

The United States could immediately lower gasoline prices, reduce our need for foreign oil, and lower emissions by importing sugarcane ethanol from Brazil. Instead, we impose a 54 cent per gallon tariff and generally make importation difficult. Instead we subsidize corn ethanol.

There is only a 20% reduction in greenhouse gases, source-to-wheels with corn ethanol in blends of up to E10, because the process of making corn ethanol uses diesel farm equipment, fertilizer from fossil fuel, coal produced electricity, and diesel fuel rail and delivery trucks. Since E10 is 90% gasoline, the blended fuel’s reduction of greenhouse gases is about 2%.

Corn ethanol is controversial. Corn farmers and others betting on high corn prices love it. Enthusiasts of energy independence support it. Some scientists show a net energy gain; some, a loss.

“Abusing our precious croplands to grow corn for an energy-inefficient process that yields low-grade automobile fuel amounts to unsustainable, subsidized food burning,” says the Cornell professor Dr. Pimentel, who chaired a U.S. Department of Energy panel that investigated the economic and environmental impact of ethanol production.

To analyze corn ethanol, one needs to look at corn-to-tank and tank-to-wheels. The real problem is in the tank-to-wheels use in U.S. flex-fuel vehicles (FFV).

If E85 (85% ethanol, 15% gasoline) corn ethanol is used is any of the 6 million GM and Ford flex fuel vehicles on U.S. streets, then greenhouse emissions increase. Most FFVs are fuel guzzlers; fueled with E85, they are corn guzzlers. In 2007 the best rated car running on E85 was the Chevrolet Impala, with a United States EPA mileage rating of 16 miles per gallon in the city and 23 on the highway when fueled with E85. For a typical U.S. year of driving, the annual fuel cost would be at $1,657 and 6 tons of CO2 would be emitted by this FFV when running on E85.

By contrast, the EPA rating for a Toyota (TM) Prius running on gasoline was 60 miles per gallon in the city and 51 on the highway. The Prius would have an annual fuel cost of $833 and only emit 3.4 tons of CO2.
A big problem is that ethanol cuts miles per gallon by about 27%. The energy content of E85 is 83,000 BTU/gallon, instead of 114,000 BTU/gallon for gasoline. To make matters worse, Dr. Pintel calculates that it takes 131,000 BTU to create a gallon of ethanol. Even by 2030, the U.S. Energy Information Administration (EIA) projects that only 1.4% of ethanol use will be E85. The vast majority will be for blending to 10% with gasoline.

The EIA forecasts that ethanol use will grow from 4 billion gallons in 2005 to 14.6 billion gallons in 2030, but only 0.2 billion gallons will be E85 by 2030.

To save gas and help save the planet, pump E10 into a gasoline miser. Don’t pump E85 into a corn guzzler. Although Dr. Pintel’s 2001 finds would also show E10 as a bad idea, U.S. agriculture has improved yields from 300 gallons of corn ethanol per acre to closer to 500 gallons in some areas, in part by using more fertilizer. The problem is now the vehicles, not the ethanol.

U.S. agriculture will be a big winner without any need to spend more tax dollars funding E85 stations, subsidizing corn ethanol, nor by blocking Brazilian ethanol and keeping gasoline prices high. Agriculture will be a bigger winner by growing cellulosic corps with much higher yields per acre than corn.

Large-scale reliance on ethanol fuel will require new conversion technologies and feedstock. Much attention has been focused on enzymes that convert plant cellulose into ethanol. Because cellulose derived ethanol is made from the non-food portions of plants, it greatly expands the potential fuel supply without cutting our precious food supplies. According to a joint study by the U.S. Departments of Agriculture and Energy, the nation has enough biomass resources to sustainably meet well over one-third of current U.S. petroleum needs if cellulosic technologies and resources are employed.”

In the heart of Silicon Valley, Khosla Ventures is funding innovative solutions for clean transportation and other major global problems. Led by Vinod Khosla, they are involved in a number of companies creating cleaner fuels with cellulosic ethanol, biomass gasification and synthetic biology.

Samir Kaul, General Partner with Khosla Ventures, was a keynote speaker at the GreenVest 2007 Conference. Leading venture capitalists were captivated by his thoughts about creating an innovation ecosystem and building a portfolio of cleantech and biotech companies. Samir was a biochemist at Venter’s Institute for Genomic Research (TIGR). Samir Kaul is also a Harvard MBA who successfully founded and built several bioscience companies. With Vinod Khosla, he founded Khosla Ventures.

Samir Kaul sees cellulosic ethanol potential yields of 2,500 gallons per acre. One of Khosla Venture’s portfolio companies is Mascoma, which is innovating in enzymes, organisms and ethanol production processes.

Another Khosla Ventures portfolio company is Range Fuels which sees fuel potential from timber harvesting residues, corn stover (stalks that remain after the corn has been harvested), sawdust, paper pulp, hog manure, municipal garbage, and more that can be converted into cellulosic ethanol. In the labs, Range Fuels has successfully converted almost 30 types of biomass into ethanol. While competitors are focused on developing new enzymes to convert cellulose to sugar, Range Fuels’ technology eliminates enzymes which have been an expensive component of cellulosic ethanol production. Range Fuels’ thermo-chemical conversion process uses a two step process to convert the biomass to synthesis gas, and then converts the gas to ethanol. The U.S. Department of Energy is negotiating with Range Fuels research funding of up to $76 million.

Range Fuels was awarded a construction permit from the state of Georgia to build the first commercial-scale cellulosic ethanol plant in the United States. Ground breaking will take place this summer for a 100-million-gallon-per-year cellulosic ethanol plant that will use wood waste from Georgia’s forests as its feedstock. Phase 1 of the plant is scheduled to complete construction in 2008 with a production capacity of 20 million gallons a year.

Ethanol is not the only bio-game in town. Many European cars and most U.S. heavy vehicles use diesel not gasoline. New generations of biodiesel, biobutanol, and synthetic fuels are being developed that could be blended with diesel or replace it. Some of these fuels could also be blended with gasoline and jet fuel. BP and Dupont have teamed to produce biobutanol.

Amyris and SunEthanol plan to use synthetic biology to develop microorganisms that produce biofuels. Khosla Ventures backed LS9 Inc. is in the early stage of using synthetic biology to engineer bacteria that can make hydrocarbons for gasoline, diesel, and jet fuel. LS9’s acting CEO, Douglas Cameron, is former director of biotechnology research at Cargill and chief scientific officer at Khosla Ventures.

The more that global customers recognize the value of green fuels, the faster will be their replacement of petroleum fuels. Carbon emissions cap-and-trade agreements are being implemented in a growing number of nations and U.S. states. The carbon market is expected to reach $40 billion by 2010. Leading investors and major corporations will convene at the Carbon Finance World this September 18-20, 2007, in Chicago to look at the opportunities.

Future vehicles will get improved mileage and use an increased mix of biofuels and fuels from synthetic biology. Expect to see a high growth of cleaner fuels from woods and waste, not food and haste. Look forward to true source-to-wheels solutions to energy independence and reduction of greenhouse gas emissions.

High-Altitude Wind Farms

by Richard T. Stuebi

Having been working in the cleantech field for almost decade, it is rare anymore for me to see or hear about something that I find revolutionary.

However, a recent article in The Economist profiled a new technology concept that threw me for a loop: a multi-pronged wind turbine contraption floating aloft like a kite, six miles in altitude in order to capture the winds of the jet stream, tethered to the ground via a transmission cable.

The company develping this technology is a San Diego firm named Sky WindPower. The company’s founder, Dave Shepard, claims that the cost of power from this technology could approach 2 cents/kwh. In addition to bringing the costs of renewables down dramatically, the technology would enable wind energy to serve baseload power requirements, given the perpetual (though not entirely constant) wind velocity of the jet stream.

I have to admit: I’m pretty skeptical of Sky WindPower’s idea. Beyond the obvious challenges about making such a technology actually work — both constructing it, launching it and controlling it — it strikes me that maintaining such an apparatus would be a nightmare, and having a bunch of cables criss-crossing the sky would no doubt pose havoc to aviation.

But, I gotta give these guys credit: they are thinking way outside the box.

Asia Pacific Partnership (APP/AP6) commentary

by Nick Bruse

Today I and a small group of people in Melbourne attended a briefing by the Business Council of Sustainable Energy and the Australian Greenhouse office on the Asia Pacific Partnership (APP) on Clean Development. This initiative was established in early 2006 by Australia, Korea, China, India, Japan and the United States.

The APP was proposed by the then Australian Minister for the Environment Senator Ian Campbell on behalf of the Australian Government as an alternative to Kyoto. This gaff was quickly amended by the Prime Minister John Howard to the statement that it presented an complimentary approach and provided a technological pathway to the worlds climate and emissions problems.

Now, 15 months on the APP has only achieved limited levels of success in providing an alternative pathway to achieving emissions reductions and in my view will not be an initiative that will achieve significant reductions in emissions.

Having said that, I do believe that the APP plays an important roll in addressing how governments and industry can work together to address technology transfer and the co-operation issues required to improve the deployment of clean technologies around the world.

The APP consists of 8 taskforces namely:

  • Clean Fossil Energy
  • Renewable Energy and Distributed Generation
  • Power Generation and Transmission
  • Steel
  • Aluminium
  • Cement
  • Coal Mining
  • Building and Appliances

The main failing that i see of the APP is firstly the limited amount of actual funding being placed into the initiative, and secondly the reluctance of the comprising tasksforces to commit to any specific targets. To date the Australian Government should be praised for having already committed A$100m over 5 years, whilst the United states is still going through approvals to provide $26m.

Of the funds committed the Australian Government has placed around $60m into projects already, around $17.5m in renewable energy projects. However when compared to the amount of funding being sunk into clean technology companies, or the capitalization of the carbon market, its a paltry sum.

When examining the goals of the RE and DG taskforce the first thing that jumps out at you is that they are not SMART (Specific, Measurable, Attainable, Realistic and Timely). The 3 goals of the taskforce are:

  1. To accelerate the development of renewable energy and distributed generation over 5 years
  2. To close the remaining gap between the cost of renewable generation and conventional generation
  3. To identify market and policy barriers and implement mechanisms to overcome such barriers to enable partners to achieve their deployment goals

According to John Lende, the Director of RE Partnerships as part of the RE & DG taskforce, it has been a struggle to achieve a level of consensus on such phrases of “5 years”, and members would have preferred a less defined target. In my mind i would question how well you can actually measure the progress achieve according to these goals.

The RE & DG taskforce however has achieved some initial progress in their 3rd meeting in March 2007 in San Diego including the development of 3 new proposals to:

  • Reduce tarrifs on RE technology
  • Develop a level of commonality of framework on emissions trading
  • Improve issues of Intellectual Property rights

All these project i think should be praised as they are essential for supporting clean technology deployment.

My main concern is that the APP by itself will never achieve emissions reductions because it is fundamentally flawed such that it sidelines political will to set targets for emissions reductions, or specific targets for technology adoptions nor implements any sort of market mechanism to price carbon. Our problem today is not that we lack the technologies to start reducing emissions, but we lack political will to affect the change rapidly.

If only we had the luxury that all governments were in agreement to implement across the board emissions reduction programs, and all we had to do was solve were a few issues of cross board technology migration.

Marketing into the Void

by Heather Rae

A chunk of my responsibilities in managing a home performance project is marketing the concept of home performance to homeowners, contractors, affiliates, trade allies, funding partners and…just about everyone. The challenge is to create awareness (and undying desire for the service) by homeowners, and awareness (and unwavering desire for providing the service…according to a set of standards and certifications) by would-be contractors. Delivering measured results to funding partners in Washington is the albatross hovering at my stern, but that’s another matter.

In a smartass mood, I called home performance a living room recital, since without brand or any other kind of recognition, it might as well be a kid playing the flute in a parlor. The name, home performance, like ‘energy efficiency’ is a mouthful of uncertain definition. The nebulous nature of marketing into a void is on some days welcomed, on others days reviled.

The mission of the program in this State is to create a sustainable market for the diagnosis and treatment of homes to make them healthy, comfortable and energy efficient. Homeowners would first have to recognize that calls to HVAC outfits, utilities, plumbers, oil delivery companies, mold and radon remediators (etc.) will get them the solution that fits that industry’s bailiwick. Call the electric utility and don’t be surprised if they try to sell an electric water heater, for example. Solar thermal will not be on the tips of their tongues. Joe Kuonen, a home performance contractor out of Arkansas, calls it the ‘one tool toolkit solution.’

Homeowners would, second, have to call on a contractor who sees the whole picture — what we call the whole-house, house-as-a-system picture. Think Bob Vila Goes Green.

There’s an old man in Maine who had his entire heating system replaced. The house was still drafty and the utility bills high. He then paid for replacement of all the windows in his house. The house was still drafty and the utility bills high. Eventually, heaven knows why or how (a good question for a marketer to answer) he called in a home performance contractor who found that the house was uninsulated. It ought to be a crime for one-tool industries to sell old men band-aid solutions, but it isn’t, and there are many stories like these from home performance contractors.

I’ve been fortunate to have The Balsam Group working on my old house. We had another walk-through this past Monday. They came over to measure for replacing the copper in the basement with PEX, but the conversation was long and complex. We decided the wisest next move in the context of a small budget would be to replace the front roof overhang and air seal the uninsulated area communicating with the space between the floors. The space between the floors has been acting as a refrigerator coil all these years. (Hey, it’s an old house, one that was built to have several wood stoves going full bore throughout the heating season — which is extensive here, like from September to June.)

I had arranged for a local roofer to fix the overhang but would have needed to coordinate his work with that of an insulation contractor who understands air sealant. (And I did not want to be arguing with anyone about air sealant versus blown-in cellulose. The latter for this particular application is O-U-T, out because there’s some knob and tube in there and because my anal tendencies around cleanliness and neatness react badly to the mess of blown-in cellulose. But that’s just me.)

Here’s the rub. The Balsam Group would be ideal for this home performance program. Not only do these design/build and renovation contractors get the green, whole-house picture, but they can actually do the work. Their carpentry is exquisite. The foundation supports they installed under the ‘ell’ are plumb and clean. Their recommendations for a new heating system account for my ‘green’ sensibilities — biofuels if we stay with oil, for example and a recognition that propane/gas is not the best idea for a leaky house. They can replace a roof membrane and air seal. Aesthetically and technically, they are right on target. And, they have no interest in plugging into the system of certifications and measuring and reporting required by government-initiated programs like mine. That’s my challenge. What’s the incentive (is there an incentive of any kind) that would get contractors like The Balsam Group to come on board? Is the best solution to create a stable of home performance consultants who tap into a network of like-minded tradespeople — leaving the testing and measuring and reporting to the consultants with energy on the brain?

It’s questions like these that make sanding and finishing floors somewhat appealing. It’s straightforward hard work with visible results. I have pretty pine floors, blisters and a good night’s sleep to prove it.

Building a green future – Light-weight high strength concrete

by Nick Bruse

When one begins to look at the built environment – examining its lifecycle, the resources and materials used in its construction and stakeholders from suppliers to developers to regulators to occupiers – a very complicated and fragmented picture arises.

This presents challenges for the property industry when trying to reduce emissions throughout the lifetime of the building. Design is important in understanding how the building will be used for its internal space, but also its load externally on the surrounding environment. Materials must be chosen to reduce embodied emissions. Construction must be achieved in a sustainable and energy efficient manor.

When i hear about technologies in the construction industry which provide benefits across a range of aspects of the industry, my interest certainly piques. One such technology is a revolutionary new light weight high stength concrete technology being produced by the Australian company HySSIL Pty Ltd in collaboration with CSIRO. I blogged briefly about this technology last year, but the more I hear about the company the more I think they have real potential.

In a recent interview I spoke with Gary Bertuch, the Managing Director of HySSIL Pty Ltd, In the interview we learn from Gary about the massive market applications of the product and of new concrete technologies they are helping the CSIRO to commercialise.

Hyssil’s technology allows the production of concrete panels that have and unique combination of lower weight, higher strength, lower embodied energy and lower construction costs due to their lightweight nature. At the same time they have excellent thermal properties than existing concrete products which minimises heat loss / absorption. Fabricated into panels, these have a strength allows them to be used in building up to 20 storeys high. The low load on foundations and hence reduced foundation requirements, means that buildings constructed of them are perfect for markets like Asia and the Middle east where alluvial or sandy soils in coastal regions normally require bedrock braced foundations.

With over 30% of emissions worldwide associated with the built environment, this technology is surely going to be a significant player in the coming years to help reduce both embodied and operating emissions from buildings and reduce the energy requirements in construction and heating.

Reflections on Illumination

by Richard T. Stuebi

While grocery shopping yesterday, I found that our local store has finally started stocking GE (NYSE: GE) compact flourescent lightbulbs (CFLs).

Candidly, my experience to date with CFLs has not been positive. Last year, I went to Home Depot (NYSE: HD), where I tend to buy household gadgets, thinking they would have the best selection of CFLs. At least back then, Home Depot didn’t carry GE CFLs (some say this was because of ex-CEO Bob Nardelli’s lingering resentment of having been passed over for Jeff Immelt when Jack Welch stepped down as CEO of GE), so I bought what Home Depot had in stock: a carton of private-label CFLs, for about $10 for a 5-pack.

I wish I could say that I was blown away by the CFLs, but regrettably, I wasn’t. In my assessment, the light quality provided by the CFLs was too pale, and it took far too long (10-20 seconds) to reach even a minimally acceptable “warm” color. Furthermore, the CFLs were not usable in many of the applications in my home: they don’t fit into lamps with tight covers/shades, and when installed to a fixture with dimmers, they emit an annoying loud buzzing sound — and an awful Snap-Crackle-Pop (and I don’t mean Rice Krispies) when the dimmer is turned down.

My initial foray into CFLs thus resulted in considerable disappointment. Although I don’t feel good about it at all, so far I’ve generally stuck with the old horribly inefficient incandescents — they at least produce a quality of light that I’ve come to expect.

I’ve been told that CFL quality varies, and that GE’s CFL products are quite a bit better — albeit more expensive — than the generic brands of the kind I had bought. I didn’t search all over town for GE CFLs, but I never saw them anywhere I happened to be shopping. Until this weekend.

Now, here in front of me finally were individually-packaged GE CFLs, the 15 watt (60 watt incandescent equivalent) priced at $4.49. Two shelves below were the standard GE incandescent 60 watt soft white lightbulbs, priced at $1.59 for a 4-pack, or about $0.40 per bulb. The CFL is thus 11 times more expensive, on a first-cost basis, than the incandescent. For the average customer, who is typically very conscious of the initial cost and pretty clueless about life-cycle economics, this is a really big spread.

In small print on the CFL packaging, GE claims that the 15 watt CFL bulb will save over its 3000-hour lifetime $13 worth of electricity (at $0.10/kwh) relative to 60 watt incandescents offering the same lumination.

$13 worth of electricity savings for an extra $4 up-front sounds like a pretty good deal. However, of course, it all depends on how many years it will take the user to generate the $13 of electricity savings — which in turn depends on how much the user uses the lightbulb.

A year is comprised of 8760 hours, so if the CFL operates 24/7, it will only take a few months to generate $13 in savings. Perhaps more importantly, it will only take a few weeks to pay back the extra $4 for the CFL instead of the incandescent. But, few of us use any lights anywhere near that much.

For a lamp used an hour a day, or about 300 hours a year, it will take 10 years to achieve the $13 in savings — or about 3 years to recover the $4 extra premium for buying the CFL instead of incandescents. A 3-year payback represents a good internal rate of return, on the order of 20%, which is far better than the long-term returns historically offered by the stock market.

So why don’t I pursue a 20% financial return? On further consideration, I am put off for two reasons.

First, I can see for sure the $4 extra leaving my hands today to buy the CFL — but I don’t have anywhere near the same degree of confidence that I’ll actually generate the economic savings at the desired pace. Will I really use the CFL about an hour a day? It might be more like 15 minutes a day, leading instead to a 12 year payback period — an outright unattractive financial return.

Second, I am strongly influenced my past negative experience with CFLs. If I buy this expensive lightbulb today, will I like its light? Will I be annoyed every time I turn it on and wait for it to have a color I can barely tolerate? Will I swap it out for a regular incandescent after a few weeks?

When I reflect upon it further, it’s the second set of considerations that put me off from buying that GE CFL. I bought CFLs in the past that I disliked, and don’t use. They were a bad investment. Even though it’s relatively small dollars involved, I don’t like making mistakes — and I really hate making the same mistake twice.

I speculate that I might not be alone in having a poor first impression of CFLs. Such a bias will probably need to be overcome by a no-cost favorable experience with a good CFL. If they really want to build the market, players like GE might consider an investment in a mass-scale public free trial — a mailbox stuffer? — of CFLs. I know that if I got a GE CFL for free, I’d give it a go — and assuming I liked the product, maybe then I’d consider buying some at $4.49 per.

A Head-Knocker

by Heather Rae

Consider a basement, a typical basement in rural Maine. Call is what it is — a cellah — a five foot high, dirt-floored head-knocker, with a boulder emerging from beneath its easternmost foundation wall. Add some radon, as radon is pervasive in these parts. Throw down some plastic sheathing; ‘affix’ this sheathing to the craggy foundation ledge with bricks and rocks. Tromp all over it in muddy boots. Add to this spider den a new 275 gallon oil tank and an older horizontal Thermapride forced air furnace. Connect the furnace to a badly built, unlined, chimney and a labyrinth of ductwork that heats only the first floor. Note the flexi-duct added as an afterthought to route warm air to the upstairs bathroom. Bring in a metered town water pipe with a spigot that does not entirely turn off the main water supply. Watch the copper plumbing waver unsecured from the floor beams. (See the plumbing break at random joints when James and John go to reconnect the copper pipes to the clothes washer. See the undulating plumbing trickle water, preventing James and John from soldering joints for hours on a Friday afternoon. Hear John ask his wife to take a taxi to a meeting; he won’t be home too soon.) Rejoice that the electrical box and wires appear to be new, functioning and properly installed (although the remnants of knob and tube wiring remain.) Consider that this homeowner would prefer the furnace and the decrepit chimney go away altogether, along with the $1800 cost to line the chimney with steel…steel because the emissions from burning oil are so corrosive. Know that I would also like a tighter, more comfortable, healthier and more energy-efficient house, whether or not this basement, this crawlspace, is included in the thermal envelope…most preferably, not. Can the house be made energy efficient enough to warrant a propane-based heating system? Rephrasing that, can it be done without huge costs for landscaping and water and radon remediation prior to air sealing and insulating? I have been jonesing for PEX (cross-linked high-density polyethylene) that won’t bust in freezing temperatures. It’s easier to install and move and repair. (I’m hoping it’s greener than copper, but that’s another matter entirely.) By replacing the copper with an insulated chase of PEX and foaming the underside of ceiling of the basement can I consider ridding the basement of the furnace and its leaky ducts and removing the chimney? Can I then phase in an on-demand hydronic heating system — the one that will heat hot water, too? It’s all so easy in theory to make a house energy efficient, but these conundrums are as painful as knocking a head on a cellah beam.

Fuel Cell 2007 Conference Highlights

By John Addison (6/19/07). Several hundred engineers, researchers, and managers shared fuel cell technology, trends, and market success at the Fuel Cell 2007 Conference. In some areas, fuel cells generate millions in revenues from commercial deployment; in other areas, fuel cells are early in research and development. A number of commercial products involve hydrogen PEM fuel cells. Business is steady for molten carbonate and phosphoric acid fuel cells. There was optimism about solid oxide fuel cells using a variety of fuels including landfill methane, natural gas, diesel, JP-8, and biomass.

In 2006, Ballard (BLDP) shipped 147 PEM fuel cells to replace lead-acid batteries in fork lifts. In large distribution and manufacturing environments, every minute counts. Fuel cells are cost justified in improving the productivity of moving goods. Fuel cells are more heat and cold tolerant, providing competitive advantage in many distribution centers.

Plug Power (PLUG) is aggressively pursuing the fork lift business. Plug recently acquired General Hydrogen, an early leader in Class 1 and 2 forklifts. Plug also acquired Celex, a leader in Class 3 forklifts. Contrary to concerns of some investors, it appears that Plug’s acquisitions may help Ballard who supplies fuel cell stacks to the acquired companies. Plug Power’s business model appears to be migrating towards integrated products and services for specific markets and applications. Ballard is a leader, in supplying fuel cell stacks; a field of growing and intensifying competition.

Toyota is also active in the hydrogen PEM forklift business since its acquisition of Raymond, a long-time provider of forklifts and material handling systems. Hydrogenics (HYGS) continues to see traction in fork lifts. Fuel cell forklift solutions are hybrid, also involving batteries for regenerative braking. Presentations forecasted 5,000 fuel cell sales in 2009 for forklifts and 20,000 in 2010.

Thanks to the sponsorship of Intelligent Energy, I was at the conference presenting One Million Hydrogen Riders in California by 2020 – An Optimistic Scenario. Free Report.

Hydrogen fuel cells are making progress in cars and heavy-vehicles. Several auto makers will be adding more vehicles in demonstration fleets this year. Several have ranges of 250-miles and more. General Motors recently demonstrated a 300-mile range with its Sequel. GM is rumored to also start demonstrating vehicles running hydrogen in internal combustion machines (HICE). GM was to speak at the conference, but cancelled at the last minute. The reason, perhaps, was a GM reorganization.

General Motors thinks its hydrogen fuel cell is ready to move out of the research lab. GM is shifting responsibility for the work from its research labs to engineering groups that develop engines and vehicles for commercial production. 500 people are being reassigned.

The shift is a sign of GM’s increasing determination to have a fuel cell vehicle on the market by around 2011. “We’re transitioning from science and research to developing real propulsion systems,” Larry Burns, GM vice president for research and strategic planning, said in an interview.

Another area of hydrogen fuel cell success is providing remote stand-by power for the telecommunications industry. Batteries in temperature-sensitive areas have failed to often. The financial stakes are too high in telecommunications to continue depending on unreliable batteries. Telecoms such as Verizon and Sprint are buying from PlugPower and ReliOn. The Western States Alliance is buying from Altergy and Hydrogenics for stand-by back-up.

Big and hot fuel cells have a growing pipeline in the 250kW to multi-MW space. FuelCell Energy (FCEL) and Fuji offer molten carbonate energy solutions with by-product heat. Projects are using natural gas, propane, biogas, and anaerobic digester (AD) gas. POSCO, a Korean steel manufacturer, ordered a 7.5MW from FCEL to reduce their heavy use of 28 cents/kWh grid electricity. Linde will distribute FuelCell Energy for water treatment.

Long-term, molten carbonate growth may be threatened by solid-oxide fuel cells (SOFC). Keenly aware of this, FuelCell Energy finalized terms with the U.S. Department of Energy (DOE) for a $36.2 million Phase I award to develop a coal-based, multi-megawatt solid oxide fuel cell-based hybrid system.

Six industry teams have successfully completed tests of the first solid oxide fuel cell prototypes that can be manufactured at costs approaching those of conventional stationary power-generation technology. Part of the U.S. Department of Energy’s Solid State Energy Conversion Alliance (SECA) program, these results reflect progress towards commercially-viable solid oxide fuel cell (SOFC) systems.

The six industry teams, led by Acumentrics, Cummins Power Generation, Delphi Automotive Systems, FuelCell Energy, General Electric, and Siemens Power Generation, designed and manufactured SOFC electrical power generators in the 3-10 kilowatt range. The industry teams’ prototypes surpassed the Department of Energy (DOE) Phase I targets. The prototypes demonstrated:

  • Average efficiency of 38.5 percent and a high of 41 percent, exceeding the DOE target of 35 percent.
  • Average steady-stage power degradation of 2 percent per 1,000 hours, besting the DOE target of 4 percent per 1,000 hours.
  • System availabilities averaging 97 percent, topping the 90 percent DOE target across the board.
  • Projected system costs ranging from $724 to $775 per kilowatt, which eclipsed the DOE intermediate target for an annual production of 250 megawatts and positions the teams to meet the 2010 target of $400 per kilowatt target.

For home stationary power applications, it will require combined heat and power (CHP) to financially justify fuel cell installations. Adaptation is predicted in markets where utility-delivered costs are high for heat and electricity, such as in Japan and Korea. Ballard will be delivering a higher temperature PEM to address the CHP market.

In the long-run, conference attendees showed more enthusiasm for SOFCs which can use existing fuels, such as kerosene in Japan and natural gas in other markets. For example, Ceres Power (CWR.L) is developing low cost and robust fuel cells that will be combined into stacks capable of generating between 1kWe and 25kWe. EDF Energy Networks, the UK’s largest electricity distributor, will be offering Ceres for home CHP.

SOFC may be the fuel cell of choice for auxiliary power on trucks and military vehicles. Delphi Automotive Systems has SOFCs in development for on vehicle use of diesel and JP-8. Cost effective removal of sulfur is a major issue, especially for the DOD’s JP-8.

Surprisingly, there was little discussion of micro fuel cells. Major Japanese consumer electronic companies were at the conference, but no products were presented. Continued reduction in power demand plus advancements in batteries and ultracapacitors may obviate micro fuel cell adoption.

The Fuel Cell 2008 Conference is planned to be in Long Beach, California, in June 2008.

The Real Price of Gasoline

by Richard T. Stuebi

A couple of weeks ago, 17 Democratic governors, including Governor Strickland of my state of Ohio, sent a letter to President Bush urging that something be done to lower gasoline prices. (News release and letter text on Governor Strickland web site)

I was contacted by an Ohio AP wire reporter to comment on this letter. In responding, I said such a letter was at best naive — just what can the President really do to lower gasoline prices? — but more importantly ill-advised. Higher energy prices help us reduce our “addiction” to oil from sources of increasing concern, as well as reduce emissions and encourage the development and adoption of new energy alternatives. In other words, I had the gall to claim that higher gasoline prices were actually good, not bad.

Of course, this was not exactly a popular position to take, and my quotes generated a bit of buzz across the state. (See example from the Coshocton Tribune) A key element of my argument was that customers are prevented from facing the true cost of gasoline, as the expenditures on military protection of oil production, refining and transportation in and around the increasingly dangerous Middle East are not recovered through gasoline taxes, but rather through income taxes.

I recalled a presentation I had heard from last summer, suggesting that these subsidies were on the order of $10/gallon. The problem was: my memory was vague, I had never seen the actual study, I wasn’t sure that I fully believed the results and couldn’t confirm its validity, but I knew that the conclusions were at least directionally correct. So, I weaseled in my interview, saying something like “Some observers have calculated the subsidy at $10/gallon.” Naturally, the reportage indicated that the $10/gallon figure was mine. I assure you: it wasn’t. I have told many people that my instinct (without any substantiating analysis) suggests that the subsidy is probably in the $3-5/gallon range. Mind you, still a meaningful number, any way you slice it.

So, after the interviews and articles, I went back to find the study that was at the root of my recollection of a $10/gallon subsidy figure. The analysis belongs to Milton Copulos, the President of the National Defense Council Foundation. Mr. Copulos apparently updated his work this past January, and he now suggests a subsidy of $8.35/gallon of gasoline refined from Persian Gulf oil. Since the Persian Gulf reflects roughly 40% of world oil production, this implies a $3.35/gallon subsidy when spread across all gallons of gasoline. That’s more in line with my expectations.

Again, a meaningful number. It means that gasoline prices should be, not $3/gallon, but on the order of $6/gallon, about what gasoline prices actually are in Europe. Moreover, this price level doesn’t include the environmental costs associated with burning gasoline. How much additional might this represent?

All told, my idea of a phased-in gasoline tax increase still seems sensible to me, so that the price signals to customers would begin to more closely match the true full cost of oil exports out of the Middle East. I was pleased to note a Cincinnati Enquirer editorial that was generally very supportive of my arguments, though less ambitious than my yearly 50 cent/gallon increase.

I don’t expect to win any votes with this position — not even in Cincinnati. Thank goodness I have no political aspirations.

Micro Fuel Cell Killer – What’s Next?

About 4 or 5 years ago micro fuel cells were quite a hot topic in cleantech. They were going to power our laptops, cell phones, PDAs, blackberries, hand held multimedia devices, etc.

The story ran like this:

The digital age and increasing customer demand for more power hungry features like bandwidth, multimedia, et al on mobile devices like laptops, PDAs and cellphones mean the increase in power requirements are outstripping the pace of technology of lithium ion battery – therefore the only solutions will be micro fuel cells. And since battery manufacturers are a plodding, unimaginative lot, silicon valley and smart scientists can build a company to leapfrog them.

We saw major players like Motorola, Toshiba, Intel, and others taking a look, and startups like Smart Fuel Cells, Medis and MTI Micro seeking to make their name on a fuel cell the size of a credit card (or thereabouts) .

Today, still no micro fuel cell powered devices are on the market, many of the larger players have gone quiet, and all the startups are talking up battery charger (not device power pack) products – especially for the military and first responders.

What happened? What killed the micro fuel cells? Can they come back? And is something similar lurking around the corner for solar, electric vehicles, biofuels, next generation batteries or one of today’s other darlings of the cleantech sector that we can learn from?

Well . . . let’s see:

The technology is actually hard – Micro fuel cell technology proved a harder nut to crack than everyone thought (at least at anywhere near the same cost point) – and the product development issues given the state of the technology proved to be a real challenge.

Rational expectations – Market reaction to the underlying drivers has been aggressive. We’ve got global warming and high energy prices making people like Sun, Dell, and others hell bent on designing power saving devices – which the consumer is now interested in buying as a premium product. Once the electronic product companies actually put their minds to reducing power usage – well, it turned out that you actually CAN optimize a device to save power, and still pack enough features in to sell product.

The incumbent technology – Despite high profile thermal issues, the incumbent lithium ion technology turned out not to be so bad, and has continued to keep pace (as far as us lowly consumers can tell) – Bottom line: I now carry 2 very small 4 hour battery packs for my laptop – I can last a transocean plane flight without needing to plug in.

Infrastructure, infrastructure, infrastructure – And yes, having to make infrastructure changes is very costly in anything energy-esque, whether its in fuel, entrenched distribution, or tooling. As usual, winning technologies in energy tend to be owned by businesses that find a way to work with existing infrastructure, not to try and replace it.

And in the end, the batteries (and the big battery makers) still rule the roost, for now.

Blogroll Review: Bottles, Biobutanol, Bagasse

by Frank Ling

DIY Solar Water Heater

The Chinese have done it again. In a country that puts waste to good use, they have found another use for beer bottles: solar water heating.

Matt James writes about a Chinese farmer who made his own solar heater in the EcoGeek blog:

“…we get the story of a man who made his family a solar hot water heater from 66 recycled beer bottles. He should have called, I could have helped him empty the bottles.”

In this setup, 66 bottles were linked by hose to collect solar energy from the sun to heat up water. The farmer says this is enough to provide water for all 3 members of his family.

Bottoms up or as the Chinese say “ganpei.”

Biobutanol Bust?

While ethanol received more attention than any other alcohol out there, it’s time to rectify situation. Methanol, which causes blindness, has a bad rap. Propanol is best known as a disinfectant.

But butanol with four carbons could be the next alcohol rock star. Scientists say it is superior fuel to ethanol.

However, it may be years until we see biobutanol pumps along the highways. Robert Rapier at R-squared Energy Blog argues that biobutanol’s time has not come yet. He says:

“Sad to say, but I believe biobutanol is dead. While research will (and should) continue, the process is currently at least 10 years from any sort of commercial feasibility. And I would point out that ‘never’ falls under the umbrella of ‘at least 10 years.'”

One of the problems with biobutanol is the energy intensive process needed to remove water from the product. Nevertheless, companies like DuPont and BP are investing heavily to develop butanol from biological processes.

Bagasse Hope

At the end of the day, ethanol still holds the spotlight. Brazil has now shown how to make ethanol even more competitive. Toward realizing energy returns from the cellulosic components from sugar cane, Dedini SA has developed a process to convert bagasse or leftover can stalk into ethanol.

Jim Fraser at the Energy Blog explains:

“The technology uses two pretreatment steps to convert bagasse, the lignocellulose-rich byproduct from cane processing, into ethanol: (1) pretreatment of the biomass with organic solvents, and (2) dilute acid hydrolysis. The innovation consists of adding a first stage pretreatment step which allows the diluted acids to do their work much faster and more efficiently. The liquid hydrolyzates are then easily fermented and distilled into ethanol.”

Now if there was only a way to convert Spam into fuel. 🙂

Carbon Taxes…Sorry, I Meant, "Fees"

by Richard T. Stuebi

For a long time, I have been assuming that U.S. regulations to reduce carbon emissions, when they come, will be in the form of a cap-and-trade program, similar to what is in place in the U.S. for limiting sulfur dioxide emissions.

Even though a cap-and-trade system for carbon emissions is probably workable, it is still (in my opinion) a less direct mechanism for reducing carbon emisisons than the more obvious: a carbon tax, priced on a $/ton emitted basis.

Carbon taxes have not found much favor because…well, they’re a tax, and no politician wants to implement a tax, as it’s deadly to one’s career ambitions. (Remember “Read my lips”?) More substantively, some have argued that a carbon tax would be harder to administer, though I would think that a cap-and-trade system would be much more cumbersome (all those allowances to track!).

For certain, a tax is a better structure dealing with emissions from all sources, large and small, whereas a cap-and-trade system is only manageable for large point source emitters — such as utility powerplants. Not surprisingly, therefore, oil and auto interests generally favor cap-and-trade as the carbon mitigation approach of choice. Perhaps somewhat surprisingly, those utilities that have gone on record in support of climate legislation are OK with a cap-and-trade approach, probably because of accumulate utility experience with cap-and-trade for sulfur dioxide.

However, FPL Group (NYSE: FPL) has cast their lot in arguing for a carbon “fee” — a tax by any other name, but a much more acceptable term. (Policy statement here) This is the first big company that I’m aware of that has gone this far out on the carbon tax limb.

True, FPL is not among the leading carbon emitters: with a large emphasis on gas, nuclear and wind for their electricity generation, they can better afford to adopt a bolder climate stance than other utilities.

But I wonder if other utilities — Exelon (NYSE: EXC) comes to mind, maybe Duke Energy (NYSE: DUK) — can be far behind? And, if so, will the pendulum swing away from cap-and-trade to carbon taxes…er, fees?

Cleantech Media Juggernaut is NOT Slowing Down

There is still lots of talk about a bubble in cleantech, in part because the media juggernaut that cleantech has become is NOT slowing down. You can always track the substance by watching what happens in the media and networking, so . . .

New things launched from some of my favorite media in cleantech:

Yahoo! has launched Yahoo! Green. The cleantech website for the mass market., my favorite stock site in this sector, has launched a Cleantech News section.

The Wall Street Journal has launched Energy Roundup of the best of the blogosphere.

Major conference operator Terrapinn has entered the cleantech sector with GreenVest 2007 coming up locally in San Francisco on June 25-27. (I’m chairing it, so I promise it will be good!). But the real draw to this one are the point and counterpoint keynotes of Khosla Ventures and Cleantech Capital Group.

And my friends at Cleantech Capital, who started it all, have launched, which since I have three of our startups actively out looking for execs, I can attest is in serious demand.

Just for grins, let us know in our comments section of any new product or website launches in cleantech and clean energy that you find of note, and whether you think they represent bubble, or substance.

Not What You Want to Hear

by Heather Rae

James Prentice and John Whitworth showed up a few weeks ago upon a recommendation from a trusted source. They are the Balsam Group: Integrated Alternative Building Solutions for the Environmentally Aware Homeowner. They call their design process, Function Form, and it starts with an examination of a clients’ needs. I have called them in to replace the rotten sill under the ‘ell’ and when they arrive, I first take them to the second floor to give them a feel of the house, along with a lighthearted narrative of my plans.

Later, James asks me to tell them what I want — all of it. I tell him it makes me sad to acknowledge what I can’t afford. I tell him I want ‘simple,’ but mean ‘minimalist.’ What I mean, really, is, this is shoestring. I am a pain in the ass. They hang with me.

We look at the bedroom wall I’d taken down (wrong wall). John says, *this* is the wall that should go away, putting a hand on the wall cutting across the upstairs landing at the foot of the stairs to the attic. We climb the steep stairs to the attic and ooh and awe at possibilities not likely to come to fruition in my lifetime. This is my favorite space in the house, because it smells of old wood and it’s peaceful and warm and nobody has buggered it but for a sprinkling of cellulose insulation under the floorboards. We look at the sad chimney and talk about the new roof and the tiny leak it still has around the chimney flashing and their method for fixing it. We talk insulation materials and drywall and painted floors. John and I joust in our frankness, and I sense that these two people are here for a reason, however painful their assessment of my reality. We look at the old wood windows and their drafty hollows that contain the window weights. Then I show them the ‘ell’ and merrily wax on: this is going to be the new kitchen!

John and James ask, what would make you most happy? Happy? I have had several energy-oriented contractors come through this house, a by-product of what I do for a living. None has asked what would make me happy; they are looking at the structure through building science and diagnostic measurements, not emotion. One even questions why, after living in the place a month, I am working on a bedroom when, from an energy perspective, it needs so much else.

Back to happy. I’m a Yankee WASP willing to forgo comfort for a buck and manage to come up with: a comfortable bedroom that doesn’t have loose plaster walls or ugly wallpaper…a kitchen that doesn’t reek of mouse piss and a faucet that doesn’t leak and actually extends over the divide in the kitchen sink…a warm place so I don’t huddle around a wood stove this winter to thaw my toes…biofuel in the oil-fired forced air furnace, now that the new energy-efficient hydronic heating system is out of the question and this 78% AFUE furnace is sticking around…an on-demand water heater to replace the water tank in the kitchen and its funky electrical components. And more.

Through my engagement with James and John, certainty erodes; my overly-turned plans take a spin into an abyss of confusion. I seek clarity and consistency in building science and do not find it; everybody has their own take. All that I have plotted in my head, all the neato energy-efficient cleantech retrofitting and remodelling I have schemed — and the information I have gathered on building science and green building — they want to see on paper. They sense, and comment on, my palpable stress. I assure them it’s not about their work. They want priorities. I contemplate this stress en route to Home Depot. I eventually type up a table of everything, including a one-car garage, putting bold Ps next to the few priorities.

Weeks later, I have taken down the wall that John has tagged. John and James have rebuilt a new wall and doorways. The new wall replaces the old plaster/lathe wall with its air leaks that flowed up through the top plates to the attic. The new drywall ceiling also stops the flow of air that was going up to the attic. Now there is an upstairs landing with ‘seasonal views’ to the Kennebec River, more light and far better feng shui than the old. The early morning fears of hemorrhaging dough, the source of my stress, give way to acceptance. I look forward to the daily arrivals of the Balsam Group.

The plans for a kitchen in the ‘ell’ have bitten the dust. James had suggested removing all the clapboard that I had scraped bare. I am crestallen. The dirt ‘slab’ under the ‘ell’ is too wet for proper insulation, for now, without signicant landscaping to control drainage. The sills will be expensive to replace. (A respected home performance contractor, looking sadly at the rotten sills, had suggested that tearing down the structure and starting over would be a less expensive alternative.) I hear from John, too, what I don’t want to hear. He says that old homes, to be properly remodelled, should be stripped and rebuilt — the clapboard should come off and be replaced with structurally insulated panels (SIPS) and an air passage, for example. In other words, a true remodel would look something like this zero energy home remodel that I found on the web: It’s an expensive proposition, to rebuild an old house, and as John says, the real estate values in these parts don’t warrant these kinds of makeovers.

While James and John work on the second floor, I scrape the grey oil paint off the floors of the bedrooms with a heat gun and sand them down with 36 grit to the original wood. Back to their bare selves, they are beautiful. This second floor project is costing far more than I had ever imagined, and if I had been presented with an estimate, after I had changed course and taken down the second wall, I would likely not have pursued it. Yet, this new space is clean, the craftsmanship beautiful — and it does have some energy upsides. It makes me happy, and like a credit card ad, that’s priceless.

Building a Company: 0 to 60 in 4 Seconds

By John Addison (6/5/07). Hundreds of Silicon Valley’s brightest minds and most successful venture capitalists joined with many of California’s political leaders on Friday night to celebrate California’s Cleantech Revolution and to raise money for the California League of Conservation Voters.

Many arrived in fuel efficient hybrids. Martin Eberhard, CEO Tesla Motors, arrived in a zero-emission vehicle that can accelerate from zero to 60 in 4 seconds. At the moment, his Tesla Roadster must be shared with the firm’s engineers who are working overtime to finish the vehicle. In October, Martin Eberhard will be driving his own Tesla. As I talked with him, it was easy to see why he was smiling.

Globally, over 40 million people now drive electric vehicles. Most are e-bikes and light electric vehicles. Most are in Asia with ranges of less than 40 miles before battery recharging becomes necessary. Few of these vehicles reach freeway speeds.

400 people have placed orders for Tesla Roadsters with 100% deposits of about $100,000 per auto. Soon they will turning heads when they drive this ultimate sports car. With the body designed and built by Lotus, the car is beautiful and aerodynamic. With the average American household having two or more cars, the Tesla with its 200-mile range is perfect for over 90% of the trips taken by Americans daily.

At the moment each Tesla has a minimum purchase price of $92,000. You will need to get in line behind Arnold Schwarzenegger, George Clooney and other luminaries who eagerly await their ordered vehicles.

Tesla is just getting started. The founders, including Martin Eberhard, have ambitions to make Tesla a major car manufacturer. On May 1, Mr. Eberhard gave the following testimony at a U.S. Senate Finance hearing:

“Tesla’s second model will be a roomy four door family car starting at $50,000, to be manufactured in our own plant in New Mexico beginning in 2009. Our third model will follow as quickly as we can, and will be more affordable still.
“Tesla intends to become a major car company with a full line of highly efficient – but also highly desirable – electric cars. Our strategy is to enter at the high end of the market, where customers are prepared to pay a premium, and then move down-market as quickly as possible to higher production levels and lower prices with each successive model. This strategy also allows us to change radically the public perception of electric cars, opening the market for a full spectrum of electric car models.”

A secret to making a five-seat sedan electric vehicle for $50,000 is lowering the cost of the battery stack. While major auto OEMs are betting on new lithium chemistry in larger form factors, Tesla integrates 6,831 commodity 18650-sized lithium-ion cells into the 56 kWh Energy Storage System (ESS) pack. The 18650 size is somewhat larger than an AA battery. The size is popular in a range of consumer electronics. Millions are made in high-volume, low cost manufacturing. Amp hours keep increasing; prices keep falling. Tesla will buy the batteries from one, or more, Japanese suppliers. The Japanese market share leaders are Sanyo, Sony, Matsushita, NEC, and Hitachi.

Tesla has devoted thousands of hours to designing and building these packs. State of charge, recharging, and heat must be managed for safety and long battery life. Cell failures must not lead to thermal runaway. Tesla’s expertise lead to a recent $43 million sale of battery packs to Th!nk, the resurrected Norwegian manufacturer of light electric vehicles. Tesla Energy Group has been established to support this and other OEM energy storage opportunities.

The energy density of lithium-ion batteries has improved 500% in 15 years. With new energy storage chemistry, future electric vehicles could go much further at even lower cost. Japan’s METI has published a roadmap to reduce battery power cost 40X by 2030. METI Roadmap

Some very bright individuals and venture capitalists continue to bet of Tesla. Early investors included PayPal founder Elon Musk, Google founders Larry Page and Sergey Brin. Tesla Motors recently completed a $45 million Series D investment round. The round was co-led by Technology Partners, a venture capital firm with a focus on Cleantech and Life Sciences, and by Elon Musk, entrepreneur and CEO of Space Exploration Technologies. A significant investment was made by Capricorn Investment Group.

All major investors from prior rounds of financing fully participated in this round, including Vantage Point Venture Partners, Draper Fisher Jurvetson, JP Morgan Bay Area Equity Fund, Valor Equity Partners and Compass Venture Partners.

With $45 million of new venture capital, Tesla Motors will build its new 150,000 square foot automobile assembly facility in Albuquerque, New Mexico, to produce the WhiteStar, This four-door, five-passenger all-electric sports sedan will utilize an aluminum chassis and body to reduce weight and extend range.

New Mexico Governor Bill Richardson has directed the state’s General Services Division, and other appropriate agencies, to investigate the purchase of 100 WhiteStar vehicles for the state fleet over a two year period as a demonstration of the state’s commitment to clean energy.

As gas prices push $4.00 per gallon, public outcry has launched a Congressional investigation of oil companies. There are growing demands for more competition. Good news. Competition is here. You need look no further than the electric outlet in your garage.
