3. Hydropower

Sorry, but wrong. Hydropower was invented in 1880.

The 1880s were also a big decade for hydropower. Hydroelectric turbines were first used to generate electricity commercially in 1880, lighting a storefront and theater in Grand Rapids, Mich. using direct current.

The first hydroelectric plant to use alternating current became operational on the Fox River in Appleton, Wisc. in 1882. It was tiny — only big enough to provide electricity for its builder’s home, the plant itself and a nearby building. But today hydropower is the largest source of renewable electricity in the U.S., generating about 6.5 percent of all the electricity in the country.

Correct!
