Video: Video summary of the 250-year history of energy in the United States
Over the 250-year history of our nation, energy consumption has evolved from wood use in the 18th and 19th centuries to today’s use of modern renewable, hydrocarbon, and nuclear technology. In 2025, total energy used in the United States was 96 quadrillion British thermal units (quads), up 2% from 2024, but below 2007’s record 99 quads. Petroleum was the most-used energy source last year, followed closely by natural gas. Use of renewable, coal, and nuclear energy each made up about 9% of total energy use.
