HYDROELECTRIC POWER
Hydroelectric power provides almost all the energy for some nations. Norway, Brazil, and the Democratic Republic of Congo all get more than 90 percent of their electricity from hydroelectric power plants. Hydroelectric energy has been in use for thousands of years. Ancient Romans built turbines, which are wheels turned by flowing water. Roman turbines were not used for electricity, but for grinding grains to make flour and breads.
Water mills provide another source of hydroelectric energy. Water mills, which were common until theIndustrial Revolution, are large wheels usually located on the banks of moderately flowing rivers. Water millsgenerate energy that powers such diverse activities as grinding grain, cutting lumber, or creating hot fires to create steel.

The first U.S. hydroelectric power plant was built on the Fox River in 1882 in Appleton, Wisconsin. This plant powered two paper mills and one home.
Does Ancient Romans built turbines? I don't imagine that they do it.
