In 2017, U.S. energy expenditures per GDP reached 5.8%, up from a record low of 5.6% in 2016, after its first annual increase since 2011. According to the U.S. Energy Information Administration, these increases are primarily a result of increased average U.S. energy prices, up almost 9% nationally from 2016 to 2017. Average U.S. prices for petroleum and natural gas increased by 14% and 13%, respectively, and electricity prices increased by 2%. Total U.S. energy consumption increased by less than 1% during the same time.
