Frequently Asked Questions

How much energy is consumed in residential and commercial buildings in the United States?

Nearly 40% of total U.S. energy consumption in 2012 was consumed in residential and commercial buildings, or about 40 quadrillion British thermal units. 

EIA has estimates for total monthly and annual energy consumption by the residential and commercial sectors, which is nearly all "building-related."  Those sectors account for nearly all the U.S. building-related energy consumption. 

Energy consumption by the commercial sector includes "non-building-related" street and other outdoor lighting, and water and sewage treatment but these are relatively small contributors to  the commercial sector's total energy consumption.  

EIA has detailed estimates for energy consumption for specific years in residential and commercial buildings, and for heating, ventilation, cooling, and lighting in manufacturing facilities. However, those data do not represent the total energy consumption for residential, commercial, and industrial sectors in those years.
