Internet tycoon Google has upped its investment into clean energy by pumping $100m into the Shepherds Flat Wind Farm, in Oregon, USA.

Expected to become the world’s largest wind farm, Shepherd’s Flat will produce 845MW of energy, the equivalent of powering 235,000 homes.

The project will deploy turbines that use permanent magnet generators- evolutionary turbine technology that will improve efficiency, reliability and grid connection capabilities. Google say the technology is an important step toward lowering the cost of wind energy over the long term in the U.S.

Rick Needham, Director of Green Business Operations, said:”Shepherds Flat will help Oregon continue to be one of the top wind producing states in the nation, while providing significant direct economic benefits to the state. The project will also benefit the region by helping California meet its aggressive renewable energy goals with a cost-effective and clean wind resource.”

The project brings Google’s total investment in clean nergy up to $350m, following their recent contribution to the BrightSource Ivanpah solar plant.

Google join the project with Caithness Energy and GE.
