Japan Builds World's Largest Floating Wind Turbine off Fukushima
by ARATA YAMAMOTO for NBC News: Engineers in Japan have installed the world's largest floating wind turbine, a towering 344-foot structure that is billed as being able to withstand 65-foot waves and even tsunamis.
The 7 megawatt turbine was fastened to the seabed last week by four 20-ton anchors about 12 miles off the Fukushima coast.
Its installation was delayed four times because of consecutive typhoons in the region. But one of its chief engineers, Katsunobu Shimizu, told NBC News that the turbine — which is about the same height as London's St. Paul's Cathedral — would be able to withstand even the most extreme conditions.
"These turbines and anchors are designed to withstand 65-foot waves," Shimizu said during a sea tour of the turbine given from a boat off the coast. "Also, here we can get 32-foot-tall tsunamis. That's why the chains are deliberately slackened."
If a large wave were to push the turbine up, down or to the side, the loose chains connecting the structure to the seabed would give it the freedom to move without being damaged, he said. Cont'd...
European offshore wind industry smashes installation record
By Madeleine Cuff for Business Green: The offshore wind industry is set for a bumper 12 months, as the latest figures from the European Wind Energy Association (EWEA) reveal installations in the first half of this year hit record levels.
As several projects reached completion and larger, more powerful turbines were deployed, new installations hit 2,342.9MW, triple the grid-connected capacity added in the same period last year. The surge in new projects makes the first six months of 2015 more successful than any other full year on record, in terms of installed capacity.
Some 584 new offshore wind turbines have been connected to the European grid so far this year, while the average turbine size has risen from 3.5MW to 4.2MW as manufacturers continue to develop more powerful turbines capable of capturing greater amounts of wind energy, the report said. Total offshore wind capacity across Europe has now reached 10,393.6MW, it added. Cont'd...
Technology Supports Global Sustainability
Cloud-based software is one technological advancement that can pay dividends in the development and management of a wide variety of renewable energy projects, from wind farms, solar farms and geothermal plants to hydropower and biomass facilities.
The Bright Idea Behind Power Classes
In order to avoid costs for AC panel upgrades, it makes sense for inverter manufacturers to provide power classes that get the most solar power on an existing customers AC panel without upgrading it.
Offshore wind power gets foothold in US with Rhode Island project
By Richard Valdmanis for Reuters: Rhode Island's Deepwater Wind began installing the foundations for North America's first offshore wind farm on Monday, a milestone the company says could pave the way for an industry long established in Europe but still struggling with opposition in the United States.
The 30-megawatt wind farm, which will include five turbines located three miles (4.8 km) off the coast of the bucolic summer tourist destination of Block Island, will take more than a year to build and is scheduled to produce electricity for the tiny island community and the mainland by the end of next year.
"Our belief is once Block Island is up and running, it will bring offshore wind from theory to reality in the United States and open up opportunities to build larger projects," said Jeffrey Grybowski, Deepwater Wind's CEO. Cont'd...
IBM Uses Machine Learning to Boost Solar for Dept of Energy
While other solar forecasting systems take more narrow location and timeframe views, whats different about the IBM approach is that we incorporate a great number of weather and solar energy prediction models. We then blend those using historical data as a function of weather situation, forecast horizon and location to create what we call a supermodel.

Hillary Clinton is calling for a 700% increase in solar power. Is that realistic?
Brad Plumer for VOX: In the coming months, Hillary Clinton's campaign is planning to release a series of proposals for dealing with global warming. Her first installment is out Sunday evening, and it calls for a large increase in renewable power.
Specifically, she's proposing to boost the amount of wind, solar, and other renewables so that they provide 33 percent of America's electricity by 2027 — enough to power every home in the country.
Part of her plan would involve accelerating the recent rapid growth of solar installations nationwide. In her proposal, Clinton calls for US solar power to grow 700 percent from current levels.
That sounds like an impossibly large number, but it's not implausible on its face. US solar capacity grew 418 percent between 2010 and 2014 (because it was starting from a small base). So 700 percent growth by 2027 is at least within the realm of possibility. But it would require additional policy changes — and clean energy prices would have to keep dropping. Cont'd...
The Nature Conservancy Installs Bird Safe Wind Power
The Nature Conservancy has completed its first phase of installation of SheerWind's INVELOX funnel-based wind power technology. Because Palmyra is home to a national wildlife refuge and more than a million nesting seabirds, conventional wind turbines were not an option due to the risk of bird strikes. What's more, the low wind speeds on the island would provide little to no energy production with traditional turbines.
The Conservancy turned to the Minnesota firm SheerWind to design the system resembling an hourglass turned on its side. Extending 83 feet horizontally with a big wind scoop at one end, an exhaust on the other, a Venturi section in the middle increases wind speed potentially three to six times. Nets over the intake and enclosed blades keep it bird friendly. The first phase of the installation includes a single turbine inside the Venturi, allowing for two additional to be installed in the near future.
The first phase of the INVELOX project is successfully charging batteries at night and on cloudy days to supplement the photovoltaic system also installed on Palmyra.

Acquisition announced for solar power supplier Vivint Solar
On July 20, SunEdison, the world's biggest renewable energy development firm, along with TerraForm Power, an owner and operator of clean energy power plants, announced the acquisition of Vivint Solar, a major supplier of residential solar systems in the U.S.
The merger will be worth approximately $2.2 billion in cash as the two major solar companies acquire the residential solar firm. Additionally, SunEdison has agreed to enter a power purchase agreement with TerraForm Power. Roughly 523 megawatts of solar power will be installed by Vivint Solar by the end of 2015, which will now all be moved over to SunEdison.
Through the $922 million power agreement, TerraForm Power will install the solar panels for residential solar protections through a "10-year average levered cash-on-cash yield of 9.5 percent," the release stated. Also, TerraForm Power will obtain future small commercial solar and completed residential projects from SunEdison's Residential and Small Commercial business unit. Cont'd...
