Top cleantech news of the day from CleanTechnica, the world's #1 cleantech or clean energy website:


Excerpts:

Inexpensive Solar Cell Coating May Lead To Big Increases In Solar Cell Efficiency, 1 Photon Knocks Loose 2 Electrons

A potentially very important development has just been announced in the field of solar cell technology. Researchers at MIT have successfully demonstrated a technique that allows a photon to knock two electrons loose, rather than only the usual one electron. The demonstration opens the door to solar cells with efficiencies higher than 30% in the near future, and potentially far higher than the 34% Shockley-Queisser efficiency “limit.” For the past couple of decades, the Shockley-Queisser … Read More

Colorado Looks To Raise Renewable Energy Standard To 25 Percent For Rural Electric Co-Ops

This post originally appeared on ThinkProgress by Matt Kasper Adoption of renewable energy standards — which require electric utility companies to produce a portion of their electricity from wind, solar, and other renewable sources — has considerably driven clean energy advances in recent years. Some 29 states and the District of Columbia have adopted hard targets for renewable energy production with another eight states setting renewable energy goals. Standards place an obligation on electricity-supply companies to reach … Read More

China Reclaims Top Spot Over US In Clean Energy Sector

Movement within the clean energy sector during 2012 has been put under the microscope by The Pew Charitable Trusts in their fourth-annual Who’s Winning the Clean Energy Race? report. Released on Wednesday, the report states that a total of 88 gigawatts (GW) of additional generating capacity was installed during 2012, despite an 11% decline in investment levels from the year previously. "Clean energy trends demonstrate the ongoing resilience of this emerging sector in the global economy," … Read More

250 MW Solar PV Power Plant Planned For Western Spain

Plans for a 250 MW solar photovoltaic plant to be built in the autonomous region of western Spain known as Extremadura were recently approved by the local government there. The exact location will be in the Royanejos municipality. The local media there have reported that that the French company Dhamma Energy is behind the project. Before the project can move further, the necessary environmental and administrative permits still need to be obtained. The project is … Read More

Italy Now Has 16.7 GW Of Installed Solar PV Capacity

Update April 19, 7:45am EDT: a reader comment has been appended to the bottom of this post. Italy’s total installed solar photovoltaic capacity now stands at an impressive 16.7 GW, as of the end of March, according to Italian energy agency Gestore dei Servizi Energetici SpA. And it is continuing to climb at a significant rate; 214 megawatts (MW) of new capacity were installed in March, 126 MW in February, and 232 MW for January. The … Read More

99% Of 2012 US Solar PV Installations Were Net Metered

In the United States, 99% of solar photovoltaic installations were net metered, signifying that net metering in the United States is preferred by far over the alternative, which is off-grid solar. I knew that net metering was popular, but I didn’t know it was that popular! The new data from the Solar Electric Power Association (SEPA) indicates that annual solar power in the US surpassed 2 gigawatts (GW) for the first time in 2012 (hitting 2.4 … Read More

Bitcoin's Environmental Problem

The world of environmental problems is bad enough without adding digital problems to the mix, but that’s just what Bitcoin has done by virtue of being the most popular digital currency currently available.  Bitcoin, for the uninitiated, is “a digital currency which was first described in a 2008 paper by pseudonymous developer Satoshi Nakamoto, who called it an anonymous, peer-to-peer, electronic payments system.” Nakamoto believed (PDF) that an “electronic payment system based on cryptographic proof instead of … Read More

State Solar Jobs Map Unveiled — Maps Of 119,000 Solar Jobs, & Much More

Toward the end of 2007, US citizens, the US labor force, experienced the troubling onset of an economic downturn. We’re still in a condition of recovery. Through the whole recovery, though, we have been pushed to consider and reconsider our value systems, our modus operandi in terms of economic sustainability — as well as the fact that economic sustainability genuinely cannot be singled out from ecological sustainability. It is time to leave those industries that … Read More
