4. Geothermal

Oops . . . geothermal power was actually invented in 1904.

Geothermal power first appeared on the energy scene in 1904 when Prince Piero Ginori Conti powered several light bulbs by tapping the geothermal steam field below his boric acid factory he owned in Tuscany. Commercial delivery occurred in 1914, but the technology didn’t catch on in the U.S. until 1960.

Nowadays geothermal power sources produce more electricity in the U.S. today — about 3 percent of all renewable power generation in the U.S. — than solar.

Correct!
