Geoscience FAQ
What are the major sources and users of energy in the United States?
Information preserved from U.S. Energy Information Administration.
Energy Information Administration's "Energy Explained" series: Energy in the United States and How the United States Uses Energy
Energy Sources in the United States
"The three major fossil fuels—petroleum, natural gas, and coal—combined accounted for about 77.6% of the U.S. primary energy production in 2017:
- Natural gas: 31.8%
- Petroleum (crude oil and natural gas plant liquids): 28%
- Coal: 17.8%
- Renewable energy: 12.7%
- Nuclear electric power: 9.6%"
Energy Uses in the United States
"The United States is a highly developed and industrialized society. Americans use a lot of energy in homes, in businesses, and in industry. Americans also use energy for personal travel and for transporting goods. There are five energy consuming sectors:
- The industrial sector [32% of all energy consumption, including electricity] includes facilities and equipment used for manufacturing, agriculture, mining, and construction.
- The transportation sector [29% of all energy consumption, including electricity] includes vehicles that transport people or goods, such as cars, trucks, buses, motorcycles, trains, aircraft, boats, barges, and ships.
- The residential sector [20% of all energy consumption, including electricity] consists of homes and apartments.
- The commercial sector [18% of all energy consumption, including electricity] includes offices, malls, stores, schools, hospitals, hotels, warehouses, restaurants, and places of worship and public assembly.
- The electric power sector consumes primary energy to generate most of the electricity consumed by the other four sectors."

Geothermal Energy
Geothermal energy is harvested by drilling into underground reservoirs of steam or water heated by the Earth. While western states like California and Nevada [lead the country in geothermal energy production](https://www.nrel.gov/images/libraries/gis-images/geothermal-capacity.jpg), emerging technologies may make it possible to extract geothermal energy throughout the United States.

Nuclear Energy
Nuclear energy is produced from fission, which splits the large atoms of heavy elements like uranium into smaller atoms, releasing enormous amounts of energy. Thirty U.S. states have nuclear power plants, and nuclear energy makes up around [20% of the U.S. electricity supply](https://www.eia.gov/energyexplained/nuclear/us-nuclear-industry.php).

Oil and Gas
Petroleum ("oil") and natural gas are hydrocarbons that formed over millions of years under heat and pressure deep in the Earth. Petroleum and natural gas are the largest sources of energy in the United States.

Renewable Energy
Renewable energy comes from sources that are constantly replenished, like running water, the heat of the Earth, the Sun's light, or wind. Renewables account for around [11% of U.S. energy consumption and 17% of electricity production](https://www.eia.gov/energyexplained/renewable-sources/).
