Colorado, known as the Centennial State, is also known for its many clean technology and sustainability highlights. The state is always looking for new projects to employ that will aid the state in reaching its renewable energy goals and decreasing carbon dioxide emissions by employing renewable energy and energy efficiency measures, including schools, (more…)

As noted in a previous post, solar patent litigation has begun to move upstream to encompass photovoltaic manufacturing equipment.

Some recent public statements by PV production equipment maker Silicon Genesis (SiGen) about startup equipment vendor Twin Creeks Technologies (more…)

The American Wind Energy Association has just released its 2011 Annual Market Report, which shows the period registered double-digit growth. The market report highlights how market certainty has been key to the creation of a “positive feedback loop” which allowed for states to generate affordable wind power electricity at record levels. (more…)

Biogas & Electric, located in San Diego, California, has developed technology that reduces harmful emissions created during anaerobic digestion.

Anaerobic digestion may serve as a renewable energy source, and reduce methane when utilized at wastewater treatment plants, dairies, and landfills. (more…)

The Case For Global Cleantech Clusters:
Presented by: The Global Cleantech Cluster Association (GCCA)

There has been an explosion of cleantech clusters around the world, promising to help accelerate financing, growth, job creation and the next generation of sustainable technologies. Contents of this article were recently published in Environmental Finance (March 2012). (more…)

A new study has found that wind farms do not have long-term detrimental effects on most bird species, but that populations of some species can decline during site construction.

In a long-term analysis of breeding and population trends for 10 bird species at 18 wind farms across (more…)

Here’s an interesting piece by Marc Gunther, suggesting that subsidies for solar have been misapplied and have created weird market conditions. No argument from me there. Handing people money to do a certain thing is a guarantee that they’ll do exactly what you’ve asked them to do – and no more. (more…)

Today we’re celebrating an interim win for California rooftop solar along with our partners at SEIA, IREC and the Sierra Club. Together we have been working to encourage the utility regulators at the California Public Utilities Commission (PUC) to clarify the methodology being used to calculate the cap on the state’s net metering program, that billing (more…)

As we have written before, Ontario in Canada is working hard to become a hub of alternative energy.

Since 2003, the province has added more than 1,200 MW of installed alternative energy, including 150 solar projects. In 2010 alone, the region added 168 MW of solar power capacity, beating New Jersey (more…)

Advanced control technologies hold perhaps the greatest potential in the wind energy industry for improvements in individual turbine and entire wind farm efficiency. Using sophisticated, nimble controllers built on innovative principles could be the key to making wind more profitable, even in light of falling government subsidies and research support. (more…)
