First-ever Terawatt-Hours Tally of Renewable Energy Released

Renewable energy generated between 665 and 673 terawatt-hours of electricity in the EU in 2010. With total energy consumption of between 3,115  and 3,175 terawatt-hours, this means that clean energy supplied about 21% of all the EU electricity used in 2010.

In an effective rebuttal to those who constantly pooh-pooh renewable energy capacity as “just nameplate capacity”, the figures were released in terawatt-hours of electricity actually produced and consumed in a year, since power generation is the bottom line for any form of electricity.

Alstom, SSE Renewables Announce World’s Largest Ocean Wave Energy Project off the Orkneys

France’s Alstom and Scotland’s SSE Renewables, on Jan. 17, announced the world’s largest ocean wave energy development project to date. The partners’ plan for the Costa Head Wave project calls for floating arrays of AWS Ocean Energy’s AWS-III wave turbines with total clean, renewable electricity-generating capacity as high as 200 megawatts (MW) to be installed in waters ranging from 60-75 meters (198-247.5 feet) deep about 5 kilometers off the coast of Orkney Main Island, according to a joint press release.

It will likely require three or more years of dedicated effort to get to the large-scale deployment stage, however. The Costa Head project will serve as the commercial proving ground for the full-scale, 2.5-MW AWS-III floating wave energy devices and AWS Ocean Energy system. A 1:9-scale prototype underwent testing at Loch Ness in 2010. Full-scale component testing is due to take place this year with support from the WATERS fund administered by Scottish Enterprise, and full-scale prototype testing is planned to take place at the European Marine Energy Centre in 2014.

Taking cues from the master Solar energy systems inspired by natural forms

Solar power: Green but inefficient

While green energy like solar power can be the answer to our power needs, there are certain hindrances to its success. First, it is expensive building the necessary equipment for harvesting the sun’s power. Next, sufficient land needs to be made available to set up a solar energy systems. Lastly, modern methods don’t allow for maximum harvesting of sunlight, which is why a lot of it goes to waste. These drawbacks pose a huge problem in attempts to replacing conventional energy with green sources. Considering solar energy systems cost about $45,000 each, most towns can’t afford to invest in them, as maximum benefits of this green energy source will be reaped only when several such systems will be installed. This is why the world still relies on conventional power even though fuel supplies are fast depleting.

Switzerland’s Berghotel Muottas Muragl is the First Energy-Plus Hotel in the Alps

The incredible Berghotel Muottas Muragl is not just a favorite mountaintop resort for some of the world’s most avid skiers – it’s also the first energy positive hotel in all of the Alps. The 104-year-old lodge just completed a year’s worth of renovations that incorporate renewable energy and sustainable living. Although the building doubled in size, its numerous solar panels, geothermal heaters, and low-impact materials have decreased the hotel’s energy consumption 64% and put it on the map as one of the most luxurious green escapes in Europe.

Air-powered bike for the future

Design student Dean Benstead has produced a bike that runs on nothing but compressed air.

He says that with further development there is a place in the future for compressed air as an economical and environmentally-friendly option.

“I wanted to explore the viability of compressed air as an alternative fuel, and my childhood experiences riding dirt bikes led me to design the motocross bike based around the Engineair engine,” says the Royal Melbourne Institute of Technology Industrial student.

WaveRoller Arrives in Portugal for Long Awaited Tests

The WaveRoller arrived on January 2nd at Portugal’s Peniche Shipyard for a much anticipated pilot test this summer off the coast of Portugal, one of the best testing sites in Europe for ocean energy. The scaled-up version for the pilot test is to be tested in the same waters near the sea shore of Peniche where its smaller prototype showed promise (Previous: WaveRoller Uses Swinging Door for Underwater Wave Energy.)

Wave energy involves very large machines that must survive harsh underwater conditions. Even this pre-commercial version weighs 280 tons, and the test has been financed by the European Commission.

Solar Arrays for the Marine Corps & Obama’s Marine One Helicopter Hanger

Americans have recently voiced support for solar energy, and the latest installation at the Marine Helicopter Squadron 1’s greenside hangar in Quantico seems to support that — it’s a 120-kilowatt solar array powered by 500 solar panels putting out a total of 150,000 kWh per year.

The solar array will be installed by FLS Energy and the solar panels will be provided by Suniva, which was chosen by FLS Energy CEO Michael Shore specifically because of its panels’ high efficiency and because it builds American. (Suniva’s panels contain more than 80% U.S. content, according to Suniva.)
