Everyone Creates a Ripple: What’s Your Ripple Effect?

The U.S. Department of Energy’s Hydropower and Hydrokinetic Office (H2O) works with researchers and experts across the country who are advancing two valuable American energy resources: hydropower and marine energy.

Each person can spark small changes—or ripples. And together, those ripples can merge to help the United States achieve its energy goals.

WPTO’s Ripple Effect profile series features just a few of the individuals whose impactful work will help advance hydropower and marine energy technologies.
