Chinese Food For Thought

On March 18, 2013, in Blog, by Richard T. Stuebi

As I posted a few years ago, so many of the best opportunities for cleantech to have immediate benefit can be found in China. Every day, evidence accumulates supporting this thesis.  Of course, this winter’s air pollution crises in Beijing and other cities made global news.  More gruesome was last week’s discovery of nearly 7,000 […]

Fifty Years

On September 24, 2012, in Blog, by Richard T. Stuebi

Earlier this month, I turned 50 years old.  Such milestones are natural occasions for reflection. Beyond recalling many of the phases and individual episodes of my life, my reflection included a consideration of how the world had changed in the 50 years in which I had lived.  And, naturally, given my profession, I pondered what it would have […]

Holy Grail 12.0: Is Our Quest At Its End?

On September 10, 2012, in Blog, by Richard T. Stuebi

I’ve been working with new energy inventions and their creators for almost 15 years now.  I don’t know how many times I’ve heard a new technology described as “the Holy Grail”:  solving all of the world’s problems forever. Well, here’s the newest one using the Holy Grail cliche:  a supposedly carbon-neutral method of using microbes […]

How About A Sane Energy Policy Mr. Obamney?

On August 30, 2012, in Blog, by Neal Dikeman

It’s Presidential Election year.  Ergo, time to discuss our 40 year whacked out excuse for an energy policy.  Royally botched up by every President since, umm? Objectives: Make US energy supply cheap for the US consumer and industry, fast growing and profitable for the American energy sector, clean, widely available and reliable, and secure, diversified, […]

Fighting the Military on Energy Strategy

On August 27, 2012, in Blog, by Richard T. Stuebi

For several years, the U.S. military has been one of the most active proponents and early-adopters of renewable energy and alternative fuels, with their Operational Energy Strategy.  Why?  Several reasons: 1.  Fuel delivered to the remote front-lines such as in Afghanistan for use in power generation and transportation has an “all-in” cost of $400/gallon.  Any energy source […]

Billion Dollar Opportunities in Cleantech

On January 6, 2011, in Blog, by David Anthony

by David Anthony It’s true. Cleantech investment hasn’t worked out exactly how people dreamt it would back in the overly-optimistic days of the last decade. One of the main obstacles deterring venture capital investors from the sector is the frequently lengthy time lag between investment and commercialization. More importantly, the number of successful cleantech exits […]

African Sunrise for Cleantech?

On December 2, 2010, in Blog, by admin

This week I’m going to break one of my self-imposed ‘blog’ rules and dip into last week’s news. My reasoning will become clear. On Thursday I attended Envirolink North West’s Developing New Technologies for off Shore Wind event at the Met in Leeds. Apart from gaining a new respect for gearboxes (not to mention the […]

A New Cleantech Taxonomy

On September 10, 2010, in Blog, by Dallas Kachan

Classic definitions of cleantech, and the industries under its umbrella, have gotten long in the tooth. The sector has changed, and taxonomies haven’t kept up. Why is a clean technology taxonomy important? As a list of nested categories, it shows where a clean technology “fits”. It helps vendors understand their competitive sets. It defines and […]

Renewable Energy Reaches over 60% of new capacity additions in 2009

On January 30, 2010, in Blog, by Jigah Shah

by Jigar Shah, Founder SunEdison and CEO of the Carbon War Room As wind come out at a robust 9.9GW in 2009, Solar at maybe 600MW, etc, it looks like the zero-emissions folks will again install a majority of incremental MWs. The balance is mostly natural gas a little bit of Coal. Getting this number […]

A Boon(e) for Wind

On July 21, 2008, in Blog, by Richard T. Stuebi

by Richard T. Stuebi It’s been about a year since T. Boone Pickens announced that his investment firm BP Capital Management (note that BP stands for “Boone Pickens”, and thus the company bears no relation to the oil behemoth BP) planned to invest about $6 billion to install the world’s largest windfarm of nominally 4,000 […]

Is Al Gore Nuts?

On July 18, 2008, in Blog, by Neal Dikeman

In his speech in Constitution Hall this week, former Vice President and renewable energy investor Al Gore extolled a stretch goal challenging America to achieve 100% renewable power within 10 years. The quote: “Today I challenge our nation to commit to producing 100 percent of our electricity from renewable energy and truly clean carbon-free sources […]

Into the Blue

On June 9, 2008, in Blog, by Richard T. Stuebi

by Richard T. Stuebi Last week, the International Energy Agency released a study entitled Energy Technology Perspectives 2008, in which the agency estimated the shifts in the world’s energy system required to reduce CO2 emissions substantially. In their so-called “BLUE” scenario (I haven’t figured out what “BLUE” refers to), a 50% CO2 reduction from 2005 […]

Edison International Says Solar is the Great Untapped Resource

On March 13, 2008, in Blog, by Neal Dikeman

Cleantech Blog had a conversation last year with Stuart Hemphill, now the newly appointed Vice President for Renewables and Alternative Energy at Southern California Edison, a subsidiary of Edison International (NYSE:EIX), one of the largest purchasers of renewable power in the US. We caught up with him again today in a lively discussion around his […]

GE: Doing Cleantech The Right Way

On March 8, 2008, in Blog, by Neal Dikeman

I have long had a respect for GE (NYSE:GE), and how it runs its business. In cleantech, I am very, very jealous. They have made themselves into the company to beat. Whether by plan, luck, or simply applying sound business discipline, GE has made itself into a top 3 global cleantech player no matter happens. […]

Cleantech Blogroll Review: Sulfur, Flipper, and Cellulose

On March 7, 2008, in Blog, by Frank Ling

by Frank Ling Sulfur Batteries The EPA has banned sulfur in gasoline but not in batteries. Sulfur, in the form of a sodium salt, has been used as large-scale storage systems. Pioneered in Japan, these batteries are gaining acceptance in the US as a reliable form of energy storage. Due to the intermittent nature of […]

On August 3, 2007, in Blog, by Frank Ling

For many people that means gaining status. Now that green is entering the mainstream, it is also a status symbol among a growing […]

$2 Bil Wind Acquisition

On March 29, 2007, in Blog, by Neal Dikeman

The cleantech sector received a huge boost this week from the news that Portugal’s EDP anounced the acquisition of Texas based Horizon Wind for a price of over $2 Bil. EDP operates globally in Spain, Portugal and Brazil. One of the intriguing aspects of this deal is the history. Horizon Wind was formerly Zilkha Renewable […]
