The federal government’s most recent data on national energy consumption found that Texas uses the most energy in total, but ranked 6th in per capita energy use.
The U.S. Energy Information Administration released data from 2015 on Wednesday that shows that Texas consumed 13 quadrillion British thermal units, or about 13 percent of total U.S. energy consumption.
A BTU is the amount of heat needed to raise the temperature of a pound of water by one degree Fahrenheit and is commonly used as unit of power for industrial purposes.
According to the federal data, Texas has consumed the most energy every year since 1960, the earliest year for which figures are available. California ranked second, consuming 8 quadrillion BTUs or about 8 percent of total U.S. energy use.
Total U.S. energy consumption in 2015 was about 97 quadrillion BTUs, a decrease of about 1 percent from the year before, the federal data showed.
But in terms of energy consumed per capita, Louisiana came in first place with 912 million BTUs per person in 2015, followed by Wyoming, Alaska, North Dakota, and Iowa.
Texas ranked sixth in per capita consumption, with 470.2 million BTUs per person.
The high per capita energy use in these states is largely attributable to industrial sector energy consumption, which accounts for more than 50 percent of all consumption in those five states, according to the U.S. Energy Information Administration.
Louisiana, Alaska, and North Dakota, for instance, are among the top 10 states in crude oil production, and Wyoming is a leading coal and natural gas producer, the federal agency found. Agriculture and manufacturing contribute to Iowa’s relatively high consumption of energy.
Meanwhile, Texas in 2015 led the nation in crude oil and natural gas production.
