While national climate change legislation was imploding this past summer, it looked like climate advocates were poised to also suffer another, even more disheartening defeat: the suspension of the most important state-level climate change law in the United States. A coalition of out-of-state oil companies and oil industry supporters had succeeded in qualifying Proposition 23 (more…)
Florida uses a ton of electricity, which explains the strong market for energy efficiency products. According to the Energy Information Administration (EIA), Florida’s per capita residential electricity demand is one of the highest in the country… due to high air conditioning use during the hot summer months and the widespread use of electricity for home heating during the winter (more…)
South Africa has the space and the sunlight, so what better region to plan a 5-gigawatt solar park that could not only generate massive amounts of solar energy, but also serve as a field test for emerging technologies in PV energy, concentrating photovoltaic PV and concentrating solar power, or CSP.
The goal is ambitious, but the path (more…)
A market analysis of the U.S. solar industry predicts that nearly 1 gigawatt of added capacity will be installed in 2010, a 114 percent increase from last year. About 314 megawatts were added during the first six months of the year, according to the report by the Solar Energy Industries Association, a trade organization. And with a major concentrated solar power project and (more…)
Wind turbines stand tall and mesmerize with their motion. Solar cells bask in the sparkling sun. Meanwhile, hidden down in the dark dirty underworld, a compelling technology sits quietly and gets no respect. Once installed it largely goes unseen and, it seems, it’s equally invisible in the world of clean technology press, venture funding and government R&D funding. Yet this technology provides some of the most (more…)
The variability of cloud patterns is a problem for solar power capturing, especially for larger solar farm operations. If grid operators could forecast or predict these changes before they occur, they would be in a better position to manage load on their grids.
Researchers at Sandia National Laboratories looked into the problem and (more…)
California, as the Global Cleantech 100 list published in the Guardian confirms, is still hot. Thirty-two of the rising stars in solar panels, energy efficiency, biofuels and more are based there.
If your electric rates are high, there is a silver lining. Chances are you live in a state that offers some of the greatest innovations and incentives for energy efficiency – or soon will. By taking advantage of these programs, you can reduce your bill.
Take a look at the chart below that I put together after reading the American Council for an Energy-Efficient Economy’s “2010 (more…)
Solar Power International 2010 (SPI 10) has 27,000 registered attendees that are eager to learn what the future holds for the solar industry.
