EIA’s recently released Annual Energy Outlook 2020 (AEO2020) projects that U.S. energy consumption will grow more slowly than gross domestic product (GDP) through 2050 as energy intensity continues its decades-long trend of decline through the AEO2020 forecast period. Energy intensity is a measure of how efficiently the economy uses energy to produce every dollar of GDP. In the AEO2020 Reference case, total U.S. energy consumption increases at an average annual rate of 0.3% between 2019 and 2050, and GDP grows at an annual rate of 1.9%, which indicates a 1.5% average annual decline in energy intensity during the projection period. By 2050, the domestic energy consumption associated with each dollar of U.S. economic growth is less than half of what it was in 2005.
