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...

A team of researchers has come up with a solar cell that produces fuel rather than electricity. A material called gallium phosphide enables the solar cell to produce clean fuel hydrogen gas from liquid water. To connect an existing silicon solar cell to a battery that splits the water may well be an efficient solution; but it is very expensive. So, researchers were streamlining their search to a semi-conductor material that is able to both convert sunlight into an electrical charge and split water. The team found gallium phosphide (GaP), a compound of gallium and phosphide, useful in this respect. GaP has good electrical properties but the drawback is that it cannot easily absorb light when it is a large flat surface as used in GaP solar cells, said the study thatappeared in Nature Communications. The researchers overcame this by making a grid of very small GaP nanowires, measuring five hundred nanometres (a millionth of a millimetre) long and ninety nanometres thick. "That makes these kinds of cells potentially a great deal cheaper," said lead author Erik Bakkers from Eindhoven University of Technology, the Netherlands. Cont'd...
There have been enough successful low-income solar pilot programs at the state and federal level that it is now possible to launch a larger initiative with confidence that it can succeed.
By Lucas Mearian, ComputerWorld: Renewable energy, combined with prolific battery storage, will soon result in vastly cheaper electricity -- and solar power that's less expensive than what fossil fuel-based power plants can produce. Additionally, solar power with lithium-ion and flow-battery storage systems will make the combination of renewable energy so inexpensive that it will surpass nuclear power and obviate the need for futuristic power sources such as fusion. That was consensus view from a several keynote speeches delivered at the Intersolar Conference in San Francisco this week. Eicke Weber, director of the Fraunhofer Institute for Solar Energy Systems, said that in sun-rich countries, the cost of solar power is already below 5 cents per kilowatt and it will continue to plummet as battery storage systems become more prolific and less expensive.

The use of a tracking system for a utility-scale project not only reduces LCOE, but also provides more usable power by broadening the power production curve to provide a smoother flow of energy from dawn to dusk.
By JASON DEAREN, Associated Press: On a vast tract of old North Carolina farmland, crews are getting ready to build something the South has never seen: a commercial-scale wind energy farm. The $600 million project by Spanish developer Iberdrola Renewables LLC will put 102 turbines on 22,000 acres near the coastal community of Elizabeth City, with plans to add about 50 more. Once up and running, it could generate about 204 megawatts, or enough electricity to power about 60,000 homes. It would be the first large onshore wind farm in a region with light, fluctuating winds that has long been a dead zone for wind power. After a years-long regulatory process that once looked to have doomed the plan, Iberdrola spokesman Paul Copleman told The Associated Press that construction is to begin in about a month. Right now, there's not a spark of electricity generated from wind in nine states across the Southeast from Arkansas to Florida, according to data from the American Wind Energy Association, an industry trade group. But taller towers and bigger turbines are unlocking new potential in the South, according to the U.S. Department of Energy, and the industry is already looking to invest. Cont'd...
Home energy storage helps whichever energy source is the cheapest, and helps the grid stay stable and available to us all.
The Obama administration on Tuesday announced an initiative to help low- and middle-income Americans gain access to solar energy, part of a series of steps President Obama is taking to tackle climate change, according to administration officials. The administration said it intends to triple the capacity of solar and other renewable energy systems it installs in federally subsidized housing by 2020, make it easier for homeowners to borrow money for solar improvements and start a nationwide program to help renters gain access to solar energy, the officials said. The actions were announced in Baltimore by Brian Deese, Mr. Obama’s senior adviser for climate issues, and Representative Elijah E. Cummings, the Democrat who represents the city. Mr. Deese, in a conference call with reporters, called the moves “part of a bigger-picture effort to try to drive innovation” toward cleaner, low-carbon energy solutions. Also unveiled on Tuesday were commitments totaling more than $520 million from charities, investors, states and cities to pay for solar and energy-efficiency projects for lower-income communities.

Unlike on-road electric vehicle programs which can be complicated and depend, in part, upon factors outside a utilitys control, non-road programs are less risky and comparatively simple to design, operate, and control.
