About This Statistic
The statistic represents U.S. energy consumption in 2014 and 2015, with a breakdown by energy source. In the United States consumed some 28.5 quadrillion British thermal units of energy derived from natural gas in 2014.
Energy consumption by source
Petroleum is the main source of energy in the United States. The liquid is predominantly utilized as a fuel in the transportation sector, which is also the second-largest consumer of energy in the U.S., with a proportion of almost 30 percent of the country’s total energy consumption. This figure is topped only by the energy-guzzling industrial sector - a major consumer of fossil fuels such as petroleum and natural gas.
Despite the prevalence of fossil fuels in the U.S. energy mix, the use of renewable energy sources has grown from around 16.8 million metric tons of oil equivalent in 2001 to approximately 65 million metric tons of oil equivalent in 2014. Most of the renewable energy produced in the United States is derived from biomass, hydro and wind sources. More often than not, renewable energy is converted into electricity. In 2014, renewable electricity accounted for more than 13.5 percent of the nation’s total electricity generation. In the long run, it is projected that renewable power will replace petroleum as the main fuel in motor vehicles, once the internal combustion motor - that revolutionized the world in the early 19th century - has been marginalized by alternative propulsion technologies.
