Energy in the USA

The primary energy consumption of USA is 2.35 Gtoe per year. This is nearly the quarter of the total primary energy consumed in the world. Fossil fuels contribute to 85% of the energy consumption and oil represents a large part of that. Nearly half (49%) of electricity is produced from coal. The amount of renewable energies is 7% but, among them, biomass and hydroelectricity represents 89% of the renewable contribution. Other renewable energies are growing fast but their overall contribution to total primary energy consumption of the USA remains small (less than 1%). This is summarized in the figure using data from the DOE.
