3. | In 2019, nuclear energy accounted for 8.45% of the United States' total energy consumption. [1] |
4. | Solar energy powered the first satellite launched into orbit by the US in 1958. [2] |
5. | The first demonstration of electricity generation from a solar cell took place in 1876, and the first windmill to generate electricity was built in 1888. [3] [3] |

7. | In Dec. of 2008 the worst coal ash spill in US history took place, spilling 1.3 million cubic meters of sludge into a valley in Tennessee. The waste contained arsenic, lead, chromium, manganese, and barium. [5] |
8. | In Apr. 2020, at the beginning of the COVID-19 stay-at-home orders, the International Energy Agency (IEA) reported overall electricity use had dropped around 15% as factories and other businesses closed temporarily. [6] |
9. | The Chinese were the first to use coal as an energy source as early as 2000 BC. The country was also the first to develop natural gas as an energy source, dating to 200 BC, and to refine petroleum (oil), dating to the 1st century. [7] [8] [9] |
10. | The first natural gas well in the United States was drilled in Fredonia, New York, by William Hart. [10] |

11. | In 1862, President Abraham Lincoln enacted an ethanol fuel tax to help finance the Civil War, crippling the industry. The tax was lifted in 1906 by President Teddy Roosevelt in order to provide a competitor to Big Oil. [11] |
12. | On Sep. 4, 1882, Thomas Edison flipped the power switch on the first electric plant in New York. The plant served a square-mile area that included the Stock Exchange and large newspapers. [12] |
13. | The Oil Pollution Act of 1924 was the first US federal law to control pollution by the oil industry by regulating fuel dumped at sea by oil-burning vessels. [13] |
14. | The first nuclear power reactor to generate electricity was built in Idaho on Dec. 20, 1951 at Argonne National Laboratory. The reactor could barely power a string of four, 100-watt light bulbs. [14] |
15. | The US Department of Energy was created on Oct. 1, 1977, after President Jimmy Carter signed the Department of Energy Organization Act on Aug. 4, 1977. [15] |
