2. Wind and Water Power Programeere.energy.gov 2 Water Power Program Mission The mission of the U.S. DOE Water Power Program is to perform research and testing, and develop innovative technologies capable of generating renewable, environmentally responsible, and cost-effective electricity from water resources. This includes efforts related to: Marine and Hydrokinetics waves, tides, and currents in oceans, estuaries, and tidal areas; free flowing water in rivers, lakes, and streams; free flowing water in man-made channels; and differentials in ocean temperature (ocean thermal energy conversion). Hydropower Efficiency increases and capacity gains at existing power stations Adding power stations at non-powered dams and constructed waterways Quantifying the value of ancillary benefits from pumped-storage and hydro Reducing costs and impacts for new sustainable hydropower developments
