The US Congress is pumping $59million (£38m) into research to develop more efficient and environmentally friendly hydropower turbines.
The National Hydropower Association welcomed the 2012 budget decision, which came over the weekend, for creating a “strong foundation” for the new energy source.
Linda Church Ciocci, executive director of the American trade body said: “From conventional hydro and conduit projects to pumped storage to ocean and tidal technologies, growth throughout the hydropower sector will play a critical role in meeting our country’s clean energy and economic goals.”
