Total imports peaked in 2005, when they represented 30% of total consumption. A consistent decline occurred over the next 15 years, as oil production doubled and domestic use receded. This allowed the United States to be a net exporter of energy for the first time in 70 years. As of 2021, the US net exports 3.9% of energy production. [18]
Energy in this sector has the same basic end uses as the residential sector, in slightly different proportions. Space conditioning is again the single biggest consumption area, but it represents only about 30% of the energy use of commercial buildings. Lighting, at 25%, plays a much larger role than it does in the residential sector. [12]
English: Historical annual US energy consumption by source between 1776 and 2024. Source: History and Prospects and U.S. Department of Agriculture Circular No. 641, Fuel Wood Used in the United States 1630–1930 Note: Data use captured energy approach to account for wind, hydro, solar, and geothermal.
According to the U.S. Department of Energy, “energy codes and standards set minimum efficiency requirements for new and renovated buildings, assuring reductions in energy use and emissions over the life of the building.” [2] As with other building codes, model energy codes and standards are often written in a language such that they can be ...
English: Pie chart of United States primary energy consumption by sector in 2015. Primary energy means from a primary source, or in simpler terms, other than from electricity which is purchased. It includes distributed generation, for example electricity locally generated from wind and solar.
This is a list of U.S. states by total electricity generation, percent of generation that is renewable, total renewable generation, percent of total domestic renewable generation, [1] and carbon intensity in 2022.
According to eurostat as of 2021, households represented 27% of final energy consumption in the EU. The main use of energy by households was for heating their homes (64.4% of final energy consumption in the residential sector), with renewables accounting for more than a quarter (27%) of EU households space heating consumption.

High energy intensities indicate a high price or cost of converting energy into GDP. On the other hand, low energy intensity indicates a lower price or cost of converting energy into GDP. The energy intensity of a country or region differs from its energy efficiency. Energy intensity is affected by climate, economic structure (e.g. services vs ...
