The 2018 edition of the Global Energy Institute’s (GEI) Index of U.S. Energy Security Risk (Index)—the eight in the series—incorporates the most recent historical and forecast data to assess the current and future state of U.S. energy security risk.
The Index is made up of 37 different measures of energy security risk in the following nine categories: global fuels; fuel imports; energy expenditures; price and market volatility; energy use intensity; electric power sector; transportation sector; environmental; and basic science and energy research & development.1 The Index covers the historical period from 1970 to 2017 and a forecast period out to 2040.
