Total Energy Consumption

The term energy consumption signifies the consumption of electricity. Energy consumption as electricity is a primary demand for households, factories, industries, complexes, and commercial places. According to a report, the total U.S. energy consumption for 2018 was 101 BTU (British Thermal Units). It accounted for 17% of the total energy consumption of the world. The total energy demand for the U.S. as oil equivalent was estimated to be about 6804 kg of oil equivalent.
