U.S. 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 countryís total energy consumption. This figure is topped only by the 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 over 50 million metric tons of oil in 2012. Most of the renewable energy produced in the United States comes from biomass, hydro and wind sources. More often than not, renewable energy is converted into electricity. In 2011, renewable electricity accounted for almost 13 percent of the nationís total electricity generation.
