Though humans have been harnessing water to perform work for thousands of years, the evolution of modern hydropower began in the late 1800’s–coincidentally at the same time that Thomas Edison and Nikola Tesla were embroiled in a battle now known as the War of the Currents.
A revolutionary river turbine device, developed with funding from DOE, will provide affordable power to a remote Alaskan village. If successful, this project will pave the way for making greater use of hydrokinetic tidal energy in the future.
After an unprecedented 92 teams registered to compete in the Energy Department-funded Wave Energy Prize, today we announced the top 20 teams. These teams all passed through Technology Gate 1: providing a thorough technical submission detailing their device and its functionality.
In order to harness the power of waves to generate electricity, engineers must be able to predict how large floating devices will perform in a dynamic environment—that is, in the water among waves. A team sponsored by the Energy Department, including members from NREL and Sandia National Laboratories, addressed that challenge and won a recent international competition.
A mill owned and operated for six generations by the Weisenberger family has been grinding grains in the heart of Kentucky since the Civil War. In 1862, August Weisenberger emigrated from Baden, Germany, to start milling grains in Midway, Kentucky. He purchased the existing three-story stone mill on the banks of South Elkhorn Creek in 1865—the perfect location to harness water power to operate the mill.
Summer is a great time to hit the water--but you don't have to go to the beach. Hundreds of hydropower dams include reservoirs where a variety of recreational activities can be enjoyed by the whole family!
The Energy Department’s New Stream-reach Development Assessment, conducted by Oak Ridge National Laboratory, has identified more than 65 gigawatts of untapped sustainable hydropower potential in U.S. rivers and streams.
