Go ahead — call me a hypocrite. I claim to be a cleantech venture capitalist yet I tell you here and now that I am not convinced of anthropogenic (human-caused) climate change (aka global warming). And I will audaciously tell you that my convictions on climate change in no way run contrary to my strong belief in the need for a cleantech revolution. (more…)

Scientists at the Massachusetts Institute of Technology (MIT) say that replacing flat solar panels with three-dimensional structures could make photovoltaic systems as much as 20 times more effective.

In a series of tests, the researchers found that such 3D structures are able to pick up light even when the (more…)

The California Public Utilities Commission approved a batch of solar contracts yesterday — up to 544 MW worth, of which 294 MW are coming in at prices below that of building a new natural gas combined cycle gas turbine. That’s a lot of solar, at a great price.

SDG&E is buying 96-150 MW, a project developed (more…)

If someone told me they could improve the efficiency of my computer so that it operates quicker, at no extra cost to me, I can’t imagine I’d turn them away. Yet, the energy efficiency industry offers a similar option for homes and businesses and at least so far, consumers aren’t flocking to the programs. (more…)

Adding a charred biomass material called biochar to glacial soils can help reduce emissions of the greenhouse gases carbon dioxide and nitrous oxide, according to U.S. Department of Agriculture (USDA) scientists. Studies by scientists with USDA’s Agricultural Research Service (ARS) are providing (more…)

The Chinese government has increased its solar energy target for 2015 by 50 percent, setting a new goal of 15 gigawatts annually, state media reports.

The new target, which was reported by China National Radio, follows a rapid surge in Chinese solar power installation in recent months after the (more…)

For much of 2011, my focus has been the Destiny USA project. This should not come as a surprise to readers who waded through my thirteen posts on the topic. I had planned to not write about the Destiny USA project again. But then I came across a press release while I was at Greenbuild: (more…)

Too often business sustainability discussions focus on pressing issues, risks, and negative outcomes as the primary drivers for change. Left to this singular purpose, our sustainability consulting practice experience has shown that these actions often lack the necessary level of engagement to be successful long-term. (more…)

If you want to stimulate solar manufacturing, you have to actually do something. Andrew Liveris, Chairman and CEO of the Dow Chemical Company, wrote a book with an entire book–”Make it in America“–on reinventing the American economy through manufacturing, especially of new energy (more…)

A U.S. government-funded report has concluded that small, modular nuclear reactors may be the best option for continuing to develop the U.S. nuclear power industry in the wake of the disaster at Fukushima, Japan.

The report, prepared by the Energy Policy Institute at the University of Chicago, said that smaller reactors (more…)
