EIA’s State Energy Data System (SEDS) recently released 2015 data estimates for all 50 U.S. states and the District of Columbia. The estimates include data on both total energy consumption and energy consumption per capita, which is calculated by dividing total consumption by population.

Texas has consumed the most energy in every year since 1960, the earliest year for which EIA has data. California ranked second in energy use, with a total consumption of 8 quadrillion Btu, about 8% of U.S. total energy use. Louisiana , Florida , and Illinois round out the top five energy-consuming states, which together account for more than one-third of total U.S. total energy use. Total energy consumption by the top 10 states exceeded […]
