The American Council for an Energy-Efficient Economy (ACEEE) has posted a new web page of national indicators of energy efficiency in the U.S. The web page shows energy efficiency trends by sector.
According to ACEEE metrics, nationally, energy productivity is trending upward over a five-year period. Productivity is the amount of service or useful work produced by a unit of energy.
Similarly, the energy intensity of the U.S. industrial sector (manufacturing, agriculture, mining, and construction) has been improving steadily. Nationally, less energy is needed per dollar of goods produced.
