The top 5 energy-consuming states also include Louisiana, Florida and Illinois – all five together account for more than one-third of total U.S. total energy use.
Vermont, in contrast, was the lowest energy-consuming state in 2015 at about 132 trillion Btu; it was the only state with a lower consumption level than the District of Columbia’s 179 trillion Btu.
Per capita energy consumption, meanwhile, was highest in Louisiana, totaling 912 million Btu (MMBtu) per person in 2015. Wyoming ranked second with 893 MMBtu, followed by Alaska (840 MMBtu), North Dakota (802 MMBtu), and Iowa (479 MMBtu).
“High per capita energy consumption in these states is largely attributable to industrial sector energy consumption, which accounts for more than 50% of all consumption in those five states,” EIA analysts pointed out.
America’s energy-intensive fossil fuel industry contributes to the high industrial sector consumption: Louisiana, Alaska, and North Dakota are all among the top ten states in crude oil production.
Wyoming, meanwhile, is a leading producer of coal and natural gas. Iowa’s agriculture and manufacturing industries contribute to its relatively high consumption of energy in the sector. Rhode Island, Delaware, Hawaii, and New Hampshire round up the top five lowest energy-consuming states which in 2015 together accounted for only 1% of total U.S. energy use.
Overall, total U.S. energy consumption in 2015 was about 97 quadrillion Btu, a decrease of about 1% year-on-year, as per EIA’s State Energy Data System which contains a complete set of state-level estimates of energy production, consumption, prices, and expenditures.
