In 2015, natural gas and electricity were tied for the leading source of energy used in homes, with each at 42%. The same two energy sources predominate in commercial buildings, where electricity (53%) and natural gas (39%) provide nearly all the energy consumed.
Electricity generation is often done with electric generators, but can also be supplied by chemical sources such as electric batteries or by other means from a wide variety of sources of energy. Electric power is generally supplied to businesses and homes by the electric power industry. Electricity is usually sold by the kilowatt hour (3.6 MJ) which is the product of power in kilowatts multiplied by running time in hours. Electric utilities measure power using electricity meters, which keep a running total of the electric energy delivered to a customer.
