green.blogs.nytimes.com For years we did a very good job at hindering domestic solar development on our own. Thanks mostly to useless Washington bureaucrats and the special interests that have long controlled them. As a result, China beat us to the punch. And they’re doing it again with wind energy, too. Do we really need [...] Renewable energy is growing fast in California. The state has mandated 33% renewable energy by 2020. That’s a long way to go and a short time to get there. Wind, solar, geothermal, big and small hydropower, tidal power, and wave power can probably get California to generate that much power by 2020. But that’s [...] Map produced by National Renewable Energy Laboratory for U.S. Department of Energy James Wimberley over at The Reality Based Community takes a look at the geographic distribution of solar, wind and geothermal sites in this country, using some nifty maps from the National Renewable Energy Laboratory (NREL), and considers some implications, including political ones. [...] The Solar Suitcase (Photo: WE CARE Solar) We’re accustomed to having electricity all the time. In fact, it’s a big deal when our power fails for a few hours or more. But there are many parts of the world where people still must routinely depend on candles or a flashlight after dark, which can [...] Austin now has the biggest solar plant in Texas at 300 MW while San Antonio plans 400 MW more in the next five years. Texas leads the country in wind power and is now moving fast on solar too.
In our experience, all of the big U.S. solar module manufactures have one approach: they sell their modules to only a few big distributors, and the more you buy, the bigger the discount. But today there is an interesting twist coming from global competitors around the world. China will sell directly to just about any [...] Several proposed big solar projects, including one in California, have switched from concentrated solar power (CSP) to the more familiar photovoltaic (PV). The trend now seems irreversible. Photovoltaic will now be the dominant technology usedfor big solar plants. CSP, with one notable exception, is losing out everywhere. CSP reflects the heat of the sun [...] The location is southwest of Phoenix. doi.gov The federal government has approved a 300 MW photovoltaic solar plant to be built in Maricopa County on public land in the Rainbow Valley south of Buckeye. The Sonoran Solar Energy Project will be the first solar project on federal land in Arizona and will provide enough [...] Solar Millennium, a German solar power company that specializes in concentrated solar power, has filed for bankruptcy. The primary reason was rapidly dropping solar photovoltaic prices and the subsequent shift from CSP to PV. The proposed 1 GW Blythe Solar Power Project in California has decided to switch from CSP to PV, which was [...] Photo credit: ACS Nano That’s the name researchers at the University of Notre Dame have given to their solar paint that uses nanoparticles to generate electricity. “We want to do something transformative, to move beyond current silicon-based solar technology,” says Prashant Kamat, John A. Zahm Professor of Science in Chemistry and Biochemistry and an [...] |  | ||||
