Boston Globe: Are falling energy prices and the collapse of the Cape Wind project undermining other offshore wind projects? A federal government auction of four leases to build wind farms off the coast of Martha’s Vineyard drew little interest, selling for a fraction of what previous auctions raised recently. Just two of 12 qualified bidders participated in the auction Thursday by the federal Bureau of Ocean Energy Management to sell wind development rights for a 1,161-square-mile swath of ocean about 14 miles south of Martha’s Vineyard. Two of the four leases did not receive any bids. One of the winning bidders, the renewable energy company RES Americas, paid $281,285 to lease 187,523 acres, while the second, New Jersey-based MW Offshore LLC, paid $166,886 for 166,886 acres. That works out to just $1.50 and $1 per acre, respectively, for each lease. In contrast, Deepwater Wind New England LLC paid about $23 an acre in 2013 with its winning bid of $3.8 million for a nearby stretch of ocean closer to Rhode Island. The federal ocean energy bureau has also sold offshore leases off the coasts of Virginia and Maryland. Despite the poor showing, officials noted the new leases would nearly double the amount of acreage the bureau has leased for offshore wind power through competitive sales.
NY Times: For more than a year now, an enormous solar thermal power plant has been humming along in the Arizona desert, sending out power as needed, even well after sunset. The plant, called Solana, was developed by the Spanish energy and technology company Abengoa and has succeeded in meeting an elusive solar goal — producing electricity when the sun is not shining — and displacing fossil-fuel-based power in the grid. “With the sun going down at 6 or 7 o’clock at night, all the other forms of solar production are essentially going to zero,” said Brad Albert, general manager for resource management at Arizona Public Service, the state’s main utility, “while Solana is still producing at full power capability. It just adds a whole lot of value to us because our customer demand is so high even after the sun goes down.” Indeed, Abengoa opened another mammoth plant on Friday in the Mojave Desert in California that uses the same approach. But despite the technology’s success, Abengoa and other developers say they do not have plans at the moment to build more such plants in the United States. And that is largely because of uncertainty surrounding an important tax credit worth 30 percent of a project’s cost. Although the subsidy, known as the Investment Tax Credit, is to remain in place until the end of 2016, when it will drop to 10 percent, that does not give developers enough time to get through the long process of securing land, permits, financing and power-purchase agreements, executives and analysts say.
America's wind installations grew six-fold in 2014, making the United States the world's second-largest wind market behind China, according to new figures out today from research firm Bloomberg New Energy Finance. US installations reached 4.7GW, thanks to the extension of the Production Tax Credit in January 2013. The extension allowed projects to qualify by starting construction before the deadline. While the US returned to growth, China continued its pattern of record-setting installations up 38% from 2013. In 2014, China installed 20.7GW – over four times more than the US – and more than 40% of all new capacity worldwide. For perspective, China has been the world's largest wind market for six years, since overtaking the US. China now has 96GW of grid-connected wind energy capacity, or more capacity than the entire power fleet of the United Kingdom. Wind energy is the country's third-largest power source behind coal and hydropower, and ahead of nuclear. China's banner year was the result of a policy-driven rush to build, as onshore tariffs are expected to lower this year. The top five Chinese turbine manufacturers Goldwind, Guodian United Power, Envision, Ming Yang, and Sewind led the market with a combined 12.4GW, or 60% of total installed capacity.
From TechCrunch: Amazon today announced that it is working with the Pattern Energy Group to construct and operate a 150 megawatt wind farm in Benton County, Indiana. The new wind farm will go online in about a year and the expectation is that it will supply at least 500,000 megawatt hours of wind power annually. That’s enough to power about 46,000 U.S. homes, but the “Amazon Web Services Wind Farm (Fowler Ridge)” — that’s the full name of what was previously called the “Fowler Ridge IV Wind Project” — will only be used to power Amazon’s AWS data centers. Amazon is not disclosing the financial details of this project, but Pattern Energy notes that this is a 13-year agreement. As Amazon announced last November, its long-term goal is “to achieve 100 percent renewable energy usage for the global AWS infrastructure footprint.” That’s a noble goal, but given that there is no date associated with these plans, it’s a bit hard to hold Amazon accountable for it. For now, Amazon offers its users three carbon-neutral regions: US West (Oregon), EU (Frankfurt) and its AWS GovCloud.
As the wind whipped off the East River Wednesday morning, Sims Municipal Recycling officially launched the city's tallest and only commercial-scale wind turbine, at its recycling center in Sunset Park, Brooklyn. The 160-foot-tall turbine has the capacity to produce 100 kilowatts, or 4 percent of Sims' power needs. Built by Northern Power Systems, the turbine cost roughly $750,000. Tom Outerbridge, Sims' general manager for recycling, said he hoped the turbine would be the first of many for the city. "On a practical level, it's offsetting our electricity costs," he said during an event to christen the turbine. "For the city, I like to think it's important that it's trying to break new ground and start to carve a path for wind projects to take off." The project took roughly four years to complete, mainly because of permitting. New York State Energy and Research Development kicked in about $130,000 as part of a statewide incentive program.
From ThinkProgress: A new study by the NC Clean Energy Technology Center finds that in all but 4 of the 50 largest cities in the U.S., installing a fully-financed 5 kilowatt solar panel system makes more financial sense than investing in a popular stock market index fund. Further, the same system would beat the costs of buying energy from local utilities in 42 of those 50 cities. “(S)olar is now not just an option for the rich, but a real opportunity for anyone looking to take greater control over their monthly utility bills and make a long-term, relatively low-risk investment,” concludes the study which was done under funding by the U.S. Department of Energy. A key qualifier in this good news study is that the benefits of installing residential solar photovoltaic systems are greatest when homeowners finance the systems (at an assumed annual interest rate of 5 percent) rather than buying them upfront. And the study does not investigate the availability of such loans. The study finds that in upfront purchases of solar, residents in just 14 out of the 50 largest U.S. cities would pay less for electricity than if they buy from their local utility. That upfront investment would be a better investment than the broad stock market index fund in 20 of the 50 cities. Cont'd....

The United Kingdom blew past previous wind power records in 2014 while Germany generated a record amount of electricity from wind in December, setting the stage for 2015 to bring more industry growth across Europe. Exactly how quickly it grows, however, is contingent upon several political and regulatory decisions to come. Using statistics from the U.K.’s National Grid, the trade association RenewableUK found that wind generated enough electricity to power just over 25 percent of U.K. homes in 2014 — a 15 percent increase from 2013. Wind turbines provided 9.3 percent of the U.K’s total electricity supply last year, a 1.5 percent boost from 2013. “It’s great to start 2015 with some good news about the massive quantities of clean electricity we’re now generating from wind,” said RenewableUK’s Deputy Chief Executive Maf Smith. In December, Germany generated more wind power, 8.9 terawatt-hours, than in any previous month. According to the IWR renewable energy research institute, this record will be overtaken in 2015 as more offshore wind farms come online.
