The developers of the world's biggest tidal array have signed a multi-million pound deal to sell electricity generated by the Scottish project. MeyGen has signed the 10-year Power Purchase Agreement (PPA) with independent energy firm SmartestEnergy for its tidal stream project in the Pentland Firth. The agreement could be worth more than £50m over its lifetime and comes just weeks after Atlantis Resources, the developer behind MeyGen, announced it had secured a major funding package to take the project forward. Under the first phase of the project, four 1.5 megawatt (MW) turbines will be installed on the seabed. Eventually the scheme could have [...]

In Science, UMass Amherst researchers tell how they broke the ‘electrode barrier' AMHERST, Mass. – For decades, polymer scientists and synthetic chemists working to improve the power conversion efficiency of organic solar cells were hampered by the inherent drawbacks of commonly used metal electrodes, including their instability and susceptibility to oxidation. Now for the first time, researchers at the University of Massachusetts Amherst have developed a more efficient, easily processable and lightweight solar cell that can use virtually any metal for the electrode, effectively breaking the “electrode barrier.” This barrier has been a big problem for a long time, says UMass Amherst's [...]

New York, September 17, 2014 – Soltage-Greenwood, a joint venture between premier North American solar power provider Soltage, LLC, and Greenwood Energy, the North and Latin American clean energy division of the Libra Group, today announced the official commissioning of a 2.7-megawatt (MW) solar power system located on Casella Waste Systems' Coventry, Vermont landfill site. The array is the largest solar project built on a landfill site in Vermont, and is expected to generate three million kilowatt-hours of electricity annually from more than 9,000 solar panels. Energy will be sold through a 25-year power purchase agreement to Vermont Electric Power Producers [...]
