This Device Could Provide a Third of America's Power
Sam Grobart for Bloomberg: There are 332,519,000 cubic miles of water on the planet. That's 352,670,000,000,000,000,000 gallons just sloshing around out there.
Anyone who's ridden or been tossed by a wave has a sense of the kinetic energy contained in our perpetually moving oceans. If we could harness it, it could provide a clean, renewable source of energy. But efforts to turn our oceans into power generators—often in the form of "aqua-mills," windmill technology adapted to water—have foundered on the complexity of their many moving parts in the corrosive and remote environs of the sea.
A new approach, developed by a company called Oscilla Power, applies all that kinetic energy to a solid piece of metal instead of using it to turn the blades of an impeller. That creates an alternating magnetic polarity in the metal that can be converted into electrical current.
Oscilla's technology, which is nearly solid-state, may prove far more durable than any other ocean-power project, increasing the chance to draw power from our oceans cleanly, meaningfully, and endlessly. View video here:

UK solar power installations plummet after government cuts
Adam Vaughan for The Guardian: The amount of household solar power capacity installed in the past two months has plummeted by three quarters following the government’s cuts to subsidies, according to new figures.
A fall in solar power was expected following a 65% reduction in government incentives paid to householders, but the size of the drop-off will dismay green campaigners who want take up on clean energy sources to accelerate.
Data published by the energy regulator this week shows there was 21 megawatts (MW) of small solar installed in February and March this year, after a new, lower incentive rate came into effect. By contrast, energy department figures show that for the same period in 2015, 81MW was installed. Cont'd...
Report: North America Could Add 75 GW Of Wind Power By 2025
From North American WindPower: According to MAKE’s latest wind power outlook for North America, unprecedented long-term policy certainty in the U.S., along with a new climate-conscious government in Canada, will enable nearly 75 GW of total wind power growth in the region from 2016 to 2025.
The production tax credit (PTC) in the U.S. was extended in December 2015 as a multiyear phaseout and will support a total of 44.4 GW of wind power additions from 2016 to 2021. However, as the value of the PTC phases down after 2018, several drivers must align to sustain wind power growth in the U.S. At the sub-regional level, Texas will lead wind power growth from 2016 to 2018, followed by the Plains and the Midwest.
Turbine technology advancement and balance-of-plant cost reductions will continue to drive down the levelized cost of electricity (LCOE) of wind power and offset a portion of the lost PTC value from 2019. This will allow wind power to maintain a substantial share of new power generation demand, despite attractive costs for natural gas power and rising competition from solar photovoltaics. Last year, the U.S. alone added nearly 8.6 GW of new wind energy generation. Cont'd...

Danish researchers may have found 'the energy source of the future'
CPH Post: Researchers at the University of Copenhagen have discovered a natural process they are calling ‘reverse photosynthesis’. They have observed how the energy in solar rays breaks down rather than builds up plant material, as happens in photosynthesis.
Sunlight is collected by chlorophyll, and when combined with a specific enzyme the energy breaks down plant biomass. The resulting product can then be used as a biofuel.
By increasing production speed while reducing pollution, the discovery has the potential to revolutionise industrial production.
“This is a game-changer, one that could transform the industrial production of fuels and chemicals, thus serving to reduce pollution significantly,” said Claus Felby, the University of Copenhagen professor who headed up the research.
“It has always been right under our noses,” he said. “Photosynthesis by way of the sun doesn’t just allow things to grow – the same principles can be applied to break plant matter down, so that the immense energy in solar light can be used so that processes can take place without additional energy inputs.” Cont'd...

Solar Power's Promise Infuses a New Film
Emily J. Gertz for TakePart: Filmmaker Shalini Kantayya set out to show that climate change isn’t all gloom and doom. The result, Catching the Sun, ably makes that case but may still leave you inspired and infuriated in equal parts.
This fast-paced and compelling new documentary, which premieres Friday in New York City and in cities nationwide during April, follows a diverse group of job seekers, activists, politicians, and entrepreneurs as they tap into the world’s growing solar powereconomy.
Kantayya jumps between nations that have unequivocally adopted policies to speed up adoption of renewables and more fitful efforts here in the United States to expand solar energy—from a program in Richmond, Virginia, training unemployed men and women to become solar panel installers to a “Green Tea Party” member and energy independence advocate working both sides of the halls of power in Georgia.

The World's Largest Renewable Energy Developer Could Go Broke
Ben Walsh for The Huffington Post: There is a “substantial risk” that SunEdison may file for bankruptcy, the world’s largest renewable energy developer said in a regulatory filing on Tuesday. The company’s fall isn’t a referendum on the solar industry as a whole, as much as it is on SunEdison’s aggressive growth strategy fueled by excessive debt and financial engineering, analysts say.
SunEdison “just thought they were smarter than everyone else,” said David Levine, the founder and CEO of Geostellar, a solar energy marketplace that has done deals with the company.
The company’s shares have fallen steeply since they hit a high of $30 in July. They were at just $1.26 before the filing. The stock immediately dropped another 40 percent when the market opened after the filing, and the company was trading at just $0.59 by Tuesday lunchtime.
“What happened from late-2014 to the middle of 2015, the company began embarking on a hyper-growth strategy,” S&P analyst Angelo Zino told The Huffington Post. Cont'd...
