New Optimism For a Cleantech Future

If you’ve not been paying much attention to cleantech in the last little while, it’s time to sit up and take notice. Because post-Solyndra, cleantech has been quietly gaining momentum. We had the chance to take a close look at the fundamentals of cleantech over the last two months in co-authoring a new (and free!) 38-page […]

My LED Saga

For my birthday, I told my wife I want LED light bulbs.  I know, right?  You’re thinking how cool is that!  If you’re thinking anything else, just keep it to yourself. A bit of history.  I like light.  I hate waiting for CFLs to warm up.  We need floodlight style for recessed lighting, and A […]

Enerkem, the Canadian Oil and Waste Rewind

At the intersection of energy and environment, a number of firms are taking on the global challenge of converting various kinds of waste into biofuels and chemicals. Montreal, Quebec-based Enerkem is not only an example, but an examplar. Operating with 10 years worth of technological validation under its belt in the area of proprietary thermochemical […]

Philips Makes LEDs Affordable

In 2008, it was the Holy Grail of residential lighting, according to off-the-gridder Dan Fink. Fink’s parameters were simple; he wanted an LED that retained (or added to) its inherent efficiency while also delivering the kind of light that homeowners identify with incandescent lighting – and all at a price that could easily nudge both […]

Kleiner-Backed Choose Energy Acquires Power2Switch

On September 30, Plano, Texas-based Choose Energy acquired Power2Switch, a Chicago-based company designed to help energy consumers negotiate their way around deregulated electricity markets in New Jersey, New York, Ohio, Texas and Illinois, where the company had its largest footprint. Founded in 2008, Choose Energy offers a user-friendly website that matches deregulated energy suppliers with […]

Making Green Mining Less Of An Oxymoron

New breakthrough science and cost reductions from the world of cleantech hold promise for making mining—one of the dirtiest, most inefficient industries in the world—more profitable, safer and cleaner. But which cleantech innovations aimed at reducing toxicity in mining, as well as the need for power and water, are best positioned to succeed? Which companies […]

Deltec Net Zero Homes: They’re Not Just a Pretty Face

Deltec Homes of Asheville, North Carolina has a new line of net zero homes, and Deltec President Steve Linton – a LEED-accredited professional – is convinced that these highly energy-efficient structures will set the cost and energy footprint standard for years to come. LEED, or Leadership in Energy and Environmental Design, a benchmark for “green” […]

Cool Energy from a Solar Heart

The title isn’t confusing once you realize that the ‘cool’ aspect stems from a technological giant step forward in Stirling engine design. Stirling engines, unlike vehicle combustion engines (which burn a fuel), work by expanding and contracting a working fluid at different temperatures. Most Stirling engines work most efficiently at about 1000 degrees Fahrenheit (1000 […]

Biosynthetic Technologies: A Future So Bright They Gotta Wear Shades

In the real world, change happens slowly. A nation, or a neighborhood, isn’t knee deep in fossil-fuel wastes one day and “green” the next. This gradual transition is something that Allen Barbieri, CEO of Irvine, California-based Biosynthetic Technologies LLC, understands very well. Biosynthetic Technologies is one of a small but growing number of energy companies […]

Tesla Motors – I Love You, But What the Hell?

I do like the Model S.  I think Tesla is doing terrific things to the car industry, direct to consumer, aggressive EV range, great looking car.  My friends who have one love it.  The company is proving it has legs.  But, as to the recent market run-up, not to be catty, but are you SERIOUS? […]

Price of Water

Water Pricing is Not the Roadblock to Water Innovation

There is a commonly held view among industry observers that “water is undervalued” and “water is underpriced”. Gloomy venture capitalists frequently cite the fact that “water is underpriced” as having the effect of hindering innovation and adoption of new technologies in the water sector (… and, incidentally of course, the ability to make good returns […]

Kior, Solar, and Storage

Kior, one of the farthest along cellulosic biofuels producers shipped its first drop in cellulosic biofuels from its pilot plant, but was way below its prior production targets.  And Biofuels Digest reports it is now considering a smaller scale expansion of its pilot before launching its long announced commercial plant in Natchez.  This sounds like […]
