Steve Dent for engadget: A five kilowatt rooftop solar installation now costs just $12,500 on average after tax credits, and pretty soon, installing one might soon be a matter of re-tiling your roof. Whether it's right for you, however, depends in large part on how much sun your house gets. That's where Google's Project Sunroof comes in -- launched just two years ago, it has now surveyed over 60 million US buildings in 50 states. That means there's a good chance you can see the electricity production potential in your city, neighborhood and even specific house. Google calculates the amount of sunlight on your roof based on "3D modeling of your roof and nearby trees," weather patterns, the position of the sun in the sky during the year and shade from buildings, trees and other obstructions. That info is then converted to energy production "using industry standard models for solar installation performance," Google says. Cont'd...

As part of the company's evolution from respected solar engineering powerhouse to one of the fastest growing EnTech companies in the country, SunLink Corporation has engaged Heritage Bank of Commerce to provide an expanded line of credit and other financial services in support of continued expansion.
Elle Hunt for The Guardian: Elon Musk, the billionaire co-founder of electric car giant Tesla, has thrown down a challenge to the South Australian and federal governments, saying he can solve the state’s energy woes within 100 days – or he’ll deliver the 100MW battery storage system for free. On Thursday, Lyndon Rive, Tesla’s vice-president for energy products, told the AFR the company could install the 100-300 megawatt hours of battery storage that would be required to prevent the power shortages that have been causing price spikes and blackouts in the state. Thanks to stepped-up production out of Tesla’s new Gigafactory in Nevada, he said it could be achieved within 100 days. Cont'd...

Sami Grover for TreeHugger: Offshore wind energy has been growing like crazy in the last few decades—so much so that there's even talk of serious talk of multi-gigawatt offshore wind farms in the US in the not too distant future. But offshore wind has so far been limited to areas where the seafloor is relatively shallow, and where it's easy to build foundations for these gigantic turbines. Floating wind turbines are different. Instead of using fixed foundations, they are anchored to the sea floor using cables. And that means they can be located in deeper waters, opening up many more areas where wind conditions are favorable and concerns about views and/or bird migration routes are less relevant. Alongside opening up new areas for development, the other major advantage of floating turbines—once they are being developed at scale—could also be reduced costs. Cont'd...
Two of the UK's biggest energy providers will now appear together at Scottish Renewables Annual Conference after new speakers were confirmed for the event.
Megan Geuss for ArsTechnica: Pumped storage is a decades-old technology with a relatively simple concept: When electricity is cheap and plentiful, use it to pump water up into a reservoir above a turbine, and when electricity is scarce and expensive, send that pumped water down through a turbine to generate more power. Often, these pumped storage facilities are auxiliary to other electricity-generating systems, and they serve to smooth out fluctuations in the amount of power on the grid. A German research institute has spent years trying to tailor pumped storage to ocean environments. Recently, the institute completed a successful four-week pilot test using a hollow concrete sphere that it placed on the bottom of Lake Constance, a body of water at the foot of the Alps. The sphere has a diameter of three meters and contains a pump and a turbine. Much like traditional pumped storage, when electricity is cheap, water can be pumped out of the sphere, and when it’s scarce, water can be let into the sphere to move the turbine and generate electricity.

Fisher Auto Parts, one of the largest regional auto parts distribution and marketing organizations in North America, announced today that the installation of a 63.7 kW photovoltaic solar energy system has been completed at their Staunton, VA headquarters.
Phys.org: A major roadblock to the mass use of solar energy are photovoltaic (PV) solar cells. This is because the cost, inefficiency and negative environmental impact that the manufacturing of these cells outweighs any potential savings provided by the resulting solar energy. If, however, cost could be were minimised, then solar power would be more able to compete with traditional fossil fuel-based methods for generating energy. To overcome this hurdle, the EU-funded SOLNOWAT project has developed an innovative dry process for manufacturing PV solar cells. PV cells are typically created via a wet chemical process that etches away layers of silicon from a crystalline wafer, leaving behind the solar cell. The SOLNOWAT process replaces the expensive and inefficient wet chemical process with the use of atmospheric pressure dry etching technology – a process that cuts costs and speeds up production. Because less silicon is removed during dry etching, the resulting cells are darker, making them very efficient at absorbing light. In fact, they are so efficient that they have been classified as having zero global warming potential. Cont'd...
