U.S. primary energy consumption in 2020 was 92.9 Quads, significantly dropping from 100.2 Quads in 2019.
The contribution of renewable energy sources exceeded 12%, while fossil fuels (natural gas, oil, and coal) made up 79%, and nuclear - 9%.
Energy consumption in transport represents 36% of overall consumption, and industry - 35%. Residential and commercial buildings consume 16.5 and 12.5%, respectively
Taking into account that more than two-thirds of the primary energy is wasted (rejected), there is a huge potential for energy efficiency improvement and CO2 emission reduction.
