New Interactive Map Reveals U.S. Tidal Energy Resources

July 13, 2011

Tidal energy—a renewable, predictable resource available up and down America’s coastlines—holds great promise for clean energy generation. And now, a first-of-its-kind database gives researchers deeper insight into the potential of this energy resource for the United States.

The online database, developed at the Georgia Institute of Technology in cooperation with DOE, maps the energy available in the nation's tidal streams. Researchers at Georgia Tech's Savannah campus used the Regional Ocean Model to simulate tidal flows along the entire U.S. coastline, which is marked by thousands of streams, rivers, and bays subject to daily tides. DOE's Oak Ridge National Laboratory validated the model's accuracy, and the resulting data are now publicly available. See the Energy Blog post.
