Energy Savers identifier

America's largest source of renewable generation is water power. To this end, the U.S. Department of Energy researches, tests, evaluates, and deploys a portfolio of innovative technologies for clean, domestic power generation from resources such as hydropower, waves, currents, and tides.

What's Driving Job Creation?

Hydropower is one of America's largest renewable energy resources, and with 50% of the U.S. population living within 50 miles of coastlines, there is vast potential to provide clean, renewable electricity to communities and cities across the United States using marine and hydrokinetic technologies. Based on the various resource assessments sponsored by the U.S. Department of Energy, the technical resource potential for United States wave, tidal, current, and riverine hydrokinetic resources is estimated to be between 1,286 and 1,787 terawatt-hours per year.

Transmission & Scalability
Water power resources are available in every region of the country, and its projects can vary in size from 1 MW small hydropower projects to 1,000 MW pumped-storage projects. 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% to 30% at seven large hydropower projects.

Workforce and Economic Need

The Brookings Institute estimates that the hydroelectric industry employs over 55,000 Americans1. In addition, the Federal Energy Regulatory Commission currently has nearly 300 preliminary hydropower permits issued. This means that nearly 300 sites are being studied and will receive priority licensing registration once their studies are complete. Each of these projects can require years of planning, construction, and operation and can create hundreds or thousands of jobs depending on project scale 2.
