SunEdison Files for Chapter 11 Bankruptcy Protection
PEG BRICKLEY and ANNE STEELE for The Wall Street Journal: Solar-energy Company SunEdison Inc. on Thursday filed for chapter 11 bankruptcy protection, a dramatic move for a company whose market value stood at nearly $10 billion in July.
SunEdison said its publicly traded entities, TerraForm Power Inc. and TerraForm GlobalInc., aren’t part of the filing. The two so-called yieldcos—separate entities that buy operating projects from developer SunEdison and pay out cash flow to their shareholders—said Thursday they believe they have sufficient liquidity to run their businesses and meet financial obligations, although SunEdison’s bankruptcy “will present challenges.”
Bankruptcy has been a near-certainty for SunEdison for some time. The company borrowed heavily to buy up wind and solar developers, accumulating a pile of debt that worried investors. Disappointing earnings didn’t ease their fears about the pace of SunEdison’s growth, and an accounting move last year that reclassified more than $700 million worth of debt heightened anxieties.

What is Hydropower in a Pipe?
According to the US Geological Survey, 66% of public water comes from surface water. Presumably some of that is pumped at some point, but even if only half of that were gravity fed, the potential for electricity production from municipal water pipes is significant.

WattJoule Develops Cost Breakthrough for Liquid Energy Storage
WattJoule Corporation, a developer of next-generation liquid electrical energy storage systems, has developed and built a new system demonstrating a major industry cost breakthrough. The new storage platform is called ElectriStor™ and will be offered to system integrators as the preferred core component for storing large amounts of solar and wind energy.
One of the major barriers preventing the widespread adoption of large-scale energy storage has been cost. WattJoule has engineered the ElectriStor™ platform based on the redox flow battery concept where electricity is stored in a liquid. WattJoule's proprietary liquid electrolyte is mostly water, and the company has developed a new, inexpensive process to make it in large quantities. Early liquid energy storage systems have suffered from a number of technical and cost limitations. Recently there have been several technical breakthroughs to overcome these constraints. WattJoule has both developed and exclusively licensed key technologies that, in combination, dramatically lower energy storage costs to $150 per kilowatt-hour in its first-generation energy storage product.

Why companies like: Google and Walmart are buying so much wind power
Brady Dennis for The Washington Post: The U.S. wind energy industry had a memorable 2015, from installing thousands of new turbines across the country to supporting a growing number of jobs.
But perhaps one of the most noteworthy brights spots of the past year, according to an annual report released Tuesday by the American Wind Energy Association (AWEA), was the growing demand for wind energy from major corporations. High-tech firms such as Google Energy, Facebook and Amazon Web Services, as well as more traditional companies such as Procter & Gamble, General Motors, Walmart and Dow Chemical, have signed contracts to purchase increasing amounts of wind energy in coming years.
Corporations and other non-utility customers — including some municipalities and universities — accounted for more than half of the wind power capacity sold through so-called power purchase agreements in 2015, according to the AWEA. The group said that corporate and other non-utility buyers have signed contracts for more than 4,500 megawatts of wind power capacity, or enough to power the equivalent of about 1.2 million American homes.

Is the U.S. Still Addicted to Oil?
Universal access to renewably-generated electricity could be within the foreseeable future, with cleaner air and water as the side effects. Better public transportation systems will make life more enjoyable for commuters all over the country, as will a self-sustaining energy economy.
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...

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...
Could uphill train tracks solve the problem of energy storage?
James Murray for BusinessGreen: is commonly regarded as a green form of travel, typically boasting lower levels of carbon emissions and air pollution than road transport, but could it also serve to deliver a cleaner and more resilient power grid?
That is the hope of innovative US start up Advanced Rail Energy Storage, LLC, which yesterday announces it has secured a crucial right-of-way lease from the Bureau of Land Management (BLM) to develop its planned 50MW gravity-based energy storage project.
The ARES Nevada project uses the same principles as pumped hydroelectric energy storage projects, but instead of relying on water in a water-stressed region it plans to make use of an inclined rail track and generator locomotive cars that will run along it. Cont'd...
