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...

Tesla Discontinues 10-Kilowatt-Hour Powerwall Home Battery

Julia Pyper for GTM:  Tesla has quietly removed all references to its 10-kilowatt-hour residential battery from the Powerwall website, as well as the company’s press kit. The company's smaller battery designed for daily cycling is all that remains. The change was initially made without explanation, which prompted industry insiders to speculate. Today, a Tesla representative confirmed the 10-kilowatt-hour option has been discontinued. "We have seen enormous interest in the Daily Powerwall worldwide," according to an emailed statement to GTM. "The Daily Powerwall supports daily use applications like solar self-consumption plus backup power applications, and can offer backup simply by modifying the way it is installed in a home. Due to the interest, we have decided to focus entirely on building and deploying the 7-kilowatt-hour Daily Powerwall at this time." The 10-kilowatt-hour option was marketed as a backup power supply capable of 500 cycles, at a price to installers of $3,500. Tesla was angling to sell the battery to consumers that want peace of mind in the event the grid goes down, like during another Superstorm Sandy. The problem is that the economics for a lithium-ion backup battery just aren’t that attractive.   Cont'd...

Solar Panels Grown on the Moon could Power Earth

Sarah Fecht for Popular Science:  Currently a high school senior in California, Lewis-Weber has just published a paper in the journal New Space with what he thinks could be the solution to the upcoming energy crisis: putting self-replicating solar panels in space. These solar panels would to build copies of themselves, autonomously, on the surface of the moon. Then they would enter Earth's orbit, collect the sun's energy, and wirelessly beam it to the ground. That may sound like a crazy idea, but the notion of space-based solar power actually dates back several decades, to the 1970s oil crisis. It was set aside after oil prices went back down, but since then, two things have happened: One, the world has become a lot more desperate to solve climate change; and two, technological innovations have brought this crazy idea out of the realm of science fiction. The idea is gaining attention, and with some big investments, it's possible that space-based solar power could become a reality within a few decades.   Cont'd...

Obama administration opens up Long Island to offshore wind development

SCOTT WALDMAN for Politico :  The federal government has designated an 81,000-acre area off of Long Island for possible commercial offshore wind development. The move by the federal Bureau of Ocean Energy Management on Wednesday to open the federal waters 11 miles off of New York to major wind development projects will be a significant boost to the Cuomo administration’s aggressive climate policies. The Bureau of Ocean Energy Management will now conduct an environmental assessment, with a possible sale of leases to follow. “New York has tremendous offshore wind potential, and today's milestone marks another important step in the President's strategy to tap clean, renewable energy from the Nation’s vast wind and solar resources,” U.S. Secretary of the Interior Sally Jewell said in a statement. “We will continue to work with the State and local stakeholders through a collaborative effort as we determine what places have the highest potential and lowest conflict to harness the enormous wind energy potential off the Atlantic seaboard.”   Cont'd...

The world's first solar airport no longer pays for electricity

Jethro Mullen for CNN:  Fed up with their hefty electricity bill, managers at Cochin International Airport in southern India took matters into their own hands. Three years ago, they began adding solar panels -- first on the roof of the arrivals terminal, then on and around an aircraft hangar. The success of those initial efforts led to a much bigger endeavor. "We wanted to be independent of the electricity utility grid," Jose Thomas, the airport's general manager, told CNNMoney. Last year, the airport commissioned the German company Bosch to build a vast 45-acre solar plant on unused land near the international cargo terminal. The plant came online in August, making Cochin the world's first fully solar-powered airport. The tens of thousands of panels generate on average slightly more than the roughly 48,000-50,000 kilowatts of power that the airport -- the seventh busiest in India -- uses per day, according to Thomas. Surplus energy is fed into the wider electricity grid. The big project cost around 620 million rupees ($9.3 million), a sum the airport expects to save in less than six years by not having to pay electricity bills anymore. It also estimates the solar plant will avoid more than 300,000 metric tons of carbon emissions from coal power over the next 25 years.   Cont'd...

After record year, U.S. energy storage forecasted to break 1 GW capacity mark in 2019

Peter Maloney  for UtilityDive:  The U.S. energy storage market put in a strong showing in 2015 with its “best quarter and best year of all time,” according to the GTM/ESA report. And current market trends point toward continued strong growth. The recent extension of the federal Investment Tax Credit, and new guidelines under consideration at the Internal Revenue Service are expected to further boost energy storage and the pairing of storage with renewable resources. In the fourth quarter alone, the U.S. deployed 112 MW of storage capacity, representing more than the total of all storage deployments in 2013 and 2014 combined. For the full year, 221 MW (161 MWh) of storage was installed. In 2014 65 MW (86 MWh) of storage was installed in the U.S.   Cont'd...

Offshore wind projects in United States see renewed interest

By PHILIP MARCELO for AP:  The offshore wind industry has high hopes for establishing a permanent beachhead in the U.S. after years of disappointment. Business leaders and politicians who gathered for an industry conference in Boston this week said wealthy investment firms and seasoned European offshore wind companies are increasingly committing to projects along the East Coast. That, they said, is evidence a domestic industry dreamed about for nearly two decades is finally on its way. "There's a palpable sense that it's finally happening," said Bryan Martin, a managing director at D.E. Shaw & Co. That New York hedge fund is the principal backer of Deepwater Wind, a Rhode Island-based company looking to launch the country's first offshore wind farm off Block Island by the end of the year. "The U.S. tends to start small and ramp up very fast. I believe that will happen with offshore wind." Among the significant new players to emerge in the past year is DONG Energy, a Danish firm that operates more than a dozen wind farms, including some of Europe's largest.   Cont'd...

The following nations have, at one point or another, broken global records in renewable energy use, production or technology development.

Warren Buffett Downplays His Battle With Elon Musk in Nevada Over Solar Power

Joe Carmichael for Inverse:  Buffett, in an interview with CNBC on Monday, responded to viewer questions about this clash (a clash that Bloomberg Business intensified with a cover story): two viewers asked why Buffett’s companies are preventing and deterring net metering in Nevada. Buffett responded: “We don’t have a problem with net meters, and we’re the leading in renewables in the country among regulated utilities. The [unintelligible] we do not want our million-plus customers that do not have solar to be buying solar at 10 and a half cents when we can turn it out for them at 4 and a half cents or buy it at 4 and a half cents. So, we do not want the non-solar customers, of whom there are over a million, to be subsidizing the 17,000 solar customers. Now, solar customers are subsidized through the Federal Government — as we are, with our wind and solar operations ourselves. … “In Nevada, [Musk's company, SolarCity] had an arrangement for a very limited number of people — and the public utility commission decides this — they had an arrangement where the utility had to pay way above market for solar produced by these 17,000 homes, and that —“ The interviewer interrupted to clarify: “For instance, if I have solar electricity that I’m producing, that’s more than I need, I can sell it back to you…”   Cont'd...
