Amid a growing call for reducing atmospheric concentrations of CO2 to 350 parts per million, a group of economists maintains that striving to meet that target is a smart investment — and the best insurance policy humanity could buy.

In the wake of a new report revealing that a clean-energy grant program in the stimulus has paid out more than $1 billion to foreign manufacturers, U.S. Senators Charles E. Schumer (D-NY), Bob Casey (D-PA), Sherrod Brown (D-OH) and Jon Tester (D-MT) urged the Obama administration Wednesday to suspend the program indefinitely until the law can be fixed so that funds only flow to projects that will create jobs in the United States.

The drive to extract and store CO2 from coal-fired power plants is gaining momentum, with the Obama administration backing the technology and the world’s first capture and sequestration project now operating in the U.S. Two questions loom: Will carbon capture and storage be affordable? And will it be safe?

There has been growing talk about a clean-tech race between China and the U.S., often cast in ominous tones. But the quest to develop and implement renewable energy can be one where both nations win.

Industrial Ecology is the practice of making industrial systems operate more like natural systems. This involves less wastage and associated benefits in terms of profitability and environmental improvement. However, in order for these systems to work it is essential that those indstries involve are capable of beneficial interaction. This article asks whether, given the required interaction options, retrofitting of industrial ecology priniciples to exisiting industry has potential.

It is a rough time to be a startup in the Solar Photovoltaic sector. The financial crisis and deep recession has not only dried up capital, but has also hit demand for solar panels, which has lead to a global supply glut and a price collapse. In this very difficult environment startups must compete with much larger established global suppliers that have factories of hundreds of megawatts each, an established customer base and well developed brand names and sales channels. In this post we look at five promising CIGS thin film Solar PV startups based in the US and try to catalog their unique strengths and accomplishments.

2010 will see extended range plug in hybrids — as well as all electric vehicles start to hit the road in significant numbers. The plugin hybrid electric vehicle (PHEV) is a primarily an electric vehicle with a small non-electric motor to extend their range; it is more of an electric vehicle and less of a gas powered vehicle than current hybrids. This post examines some of the main players in this emerging electic vehicle sector.

While the scientific evidence for climate change grows, the policy responses have so far had little or no impact on the build-up of emissions. Following the recent developments in Copenhagen, there are few signs that this will change in the near future. With this in mind, this article examines why there is still such a gap between what science says is needed, and what is actually achieved through policy.

Last week, Ethical Markets Media and The Climate Prosperity Alliance launched their Global Climate Prosperity Scoreboard, which tracks private investment in companies growing the green economy globally. This new, never before reported number, showing $1,248,740,645,993.00 (over $1.248 trillion) in total investment since 2007, indicates how investors and entrepreneurs are leading governments in promoting sustainable growth. The scoreboard totals investments in solar, wind, geothermal, ocean/hydro, energy efficiency and storage, and agriculture.
