1. Solar Power

Ah, in fact, solar power was invented in 1883.

The invention of the first silicon solar cell was announced by Bell Labs in April 1954 in Murray Hill, N.J.

But rudimentary solar cells go back much farther, to 1883, when American inventor Charles Fritts created the first solar cell in the world. Extremely inefficient and expensive to produce, the solar cell Fritts made was constructed of selenium and coated in gold. Silicon solar cells and mirrors today are much cheaper and efficient and provide about 2 percent of all electricity produced by renewables in the U.S.

Correct!
