FIGURE 1.5 Annual per capita energy use (in million Btu per capita) as a function of gross domestic product (GDP) at purchasing-power parity per capita. A progression over time for several representative countries is shown. GDP is a measure of economic activity. On average, higher per capita energy consumption is associated with increasing per capita GDP; however, in some cases, per capita GDP has increased while energy use has declined.
