An american flag is attached to the top of the yellow buoy. The U.S. Department of Energy (DOE) leads the growing global effort to tap the power of the ocean's waves and tides, while supporting innovations to optimize U.S. hydropower production. DOE's assessments of wave and tidal energy resources show the potential to generate 1,420 terawatt-hours of electricity each year off U.S. coasts. DOE is supporting testing and deployment of the nation's first wave and tidal energy projects, and launched the first federally funded hydropower facility upgrades in more than 20 years—increasing generation by 7%–30% at seven large hydropower projects. DOE also helped develop "fish-friendly" hydropower turbines that improve fish survival rates to more than 98% without sacrificing efficiency.
 

Water Power Program

The Water Power Program, part of the Wind and Water Power Technologies Office, researches, tests, evaluates, and develops innovative technologies capable of generating renewable, environmentally responsible, and cost-effective electricity from water resources. This includes hydropower, as well as marine and hydrokinetic energy technologies, which capture energy from waves as well as riverine, tidal, and ocean currents.
