Energy can be divided into two categories: non-renewable and renewable. The non-renewable energies are fossil fuels (oil, natural gas and coal) and uranium. The renewable energies are solar, wind, geothermal, biomass, and hydropower. U.S. energy consumption in 2014 was led by petroleum, followed by natural gas, coal, renewable energy, and nuclear power, respectively. Petroleum accounted for 34.8% of total energy used, of which, 71% went to the transportation sector, 23% to the industrial sector, 4% to the residential and commercial sector, and 1% to the electric power sector. Natural Gas usage was 27.5% of the total energy used, of which, 34% went to the industrial sector, 32% went to the residential and commercial sector, 30% went to the electric power sector, and 3% went to the transportation sector. Coal usage was 17.9% of the total energy used, of which, 91% went to the electric power sector, 8% to the industrial sector and 1% to the residential and commercial sector. Renewable Energy usage was 9.6% of the total energy used, with over half of it going to the electric power sector. Lastly, Nuclear power accounted for 8.3% of the total …show more content…
