U.S. energy consumption has slowed recently and is not anticipated to return to growth levels seen in the second half of the 20th century. EIA's Reference case projections in the Annual Energy Outlook 2015 (AEO2015) show that domestic consumption is expected to grow at a modest 0.3% per year through 2040, less than half the rate of population growth. Energy used in homes is essentially flat, and transportation consumption will decline slightly, meaning that energy consumption growth will be concentrated in U.S. businesses and industries.
