Iceland Home to World’s First Zero-Emissions Data Center

September 30th, 2011 | by Andrew

UK telecoms and IT provider Colt is well on its way toward building the world's first zero-emissions data center, in all of four months. Being built for data center developer Verne Global, the plant will be built on a former NATO base in Keflavik, Iceland, where geothermal and hydroelectric power will supply all the electricity needed to power the 500-square meter data center's servers and ambient cold air used to cool them


Kyoto University to Test Solar Array in Space (in 5-10 Years)

September 29th, 2011 | by Charis Michelsen

The idea of parking solar panels in orbit and letting them rain energy down upon Earth has been explored both in science fiction and in research laboratories for decades. Kyoto University announced this week that it took the first step in actually creating such a satellite, in its billion-yen test facility at Uji Campus


400-Megawatt Solar Farm Planned in Northern Florida

September 29th, 2011 | by Glenn Meyers

National Solar Power has announced it will build the Southeast’s largest solar farm in Gadsden County, Florida. The planned 400-megawatt solar farm – a $1.5 billion investment – is expected to generate hundreds of new jobs in the renewable energy sector


Quantum Dot Solar Cell Improvements Show Remarkable Potential to Balance Solar Performance & Cost

September 28th, 2011 | by Glenn Meyers

As far as innovation on the technology front, this one is a winner. In tabulating efficiency ratings, however, quantum cells don't seem to perform as well as either silicon-based or CIGS solar cells. This may soon change. Nature Materials writes that a new efficiency record for wrapping colloidal quantum dot solar cells may represent a step towards narrowing the gap


Shake Remote, Turn Off Television

September 28th, 2011 | by Charis Michelsen

With potential laptops powered by typing and watches powered by moving one's arm, energy harvesting is a growing field with a number of cool products. In Japan, Murata Manufacturing is firmly on board the trend with sensors to detect and convert vibration, temperature gradient, ambient heat, and light into small amounts of electricity. Their most recent offering uses a variety of their sensors in combination with a flexible plate to send several different signals without the need for batteries


Responding to a Trillion-Dollar Call to Retrofit Buildings

September 28th, 2011 | by Guest Contributor

The serial entrepreneur Sir Richard Branson brought to life an international need and business opportunity centered on thermally upgrading existing buildings, the world’s biggest users of energy. NYC’s Empire State Building was able to reduce its energy use by 40% thanks to a retrofit. Sir Richard founded the “Carbon War Room” based in Washington D.C. to unite international entrepreneurs, business leaders, researchers, policy experts, thinkers, to focus on solutions, not rhetoric, in efforts to tangibly combat climate change while creating 1000’s of “green” jobs


SolarWindows from New Energy Technologies

September 28th, 2011 | by Zachary Shahan

We've covered these Solar Windows from New Energy Technologies in the past, but sister site Green Building Elements recently did a slightly more detailed piece on them, so I thought I'd share it


German Small Solar Cheaper Than U.S. Big Solar

September 28th, 2011 | by John Farrell

The U.S. has a hodge-podge of utility, state and federal tax-based incentives. The Germans have a comprehensive feed-in tariff, providing CLEAN contracts (in the U.S. parlance) to anyone who wants to go solar (or wind, or biogas, etc). What does that mean for the price of solar


Peugeot Jumps on the Tiny-e-Car Bandwagon

September 27th, 2011 | by Charis Michelsen

Tiny short-range electric cars with room for one or two were not uncommon at the IAA 2011 – VW brought the Nils, Audi had the Urban Concept, and Opel showed the Rak e. Peugeot missed the auto show, but has announced its own tiny electric car anyway – the Velv
