Hydropower in the Days of Yore

From the U.S. Department of Energy Office of Energy Efficiency and Renewable Energy:

For #TBT, we take you back to the 1860s when this mill in #Kentucky first started using water power to grind its grain. Flash forward to today: thanks to funding support from the Energy Department, the Weisenberger Flour Mill now uses an advanced small #hydropower unit to run the mill, and may also sell excess #electricity to the local utility in the future, so more Kentuckians can use clean #energy.
