1 Hydropower is the most efficient way to generate electricity. 2  Modern hydro turbines can convert as much as 90% of the available energy into electricity. 3  The best fossil fuel plants are only about 50% efficient. ( 4 1). 5  In the U.S., hydropower is produced for an average of 0.85 cents per kilowatt-hour (kwh). World-wide, about 20% of all electricity is generated by hydropower. ( 2 1). 3  Hydropower provides about 10% of the electricity in the United States. ( 4 1). 5  The United States is the second largest producer of hydropower in the world.
