Consumption stats

U.S. and E.U. energy consumption per capita on downward trend

2020 energy usage per person including electricity, heating, transportation

  • U.S. ~ 74,000 kWh
  • Japan ~ 37,000 kWh
  • Germany ~ 40,000 kWh

Home energy consumption by source

U.S. households

  • Space heating – 43%
  • Air conditioning – 8%
  • Water heating – 19%
  • Lighting – 5%
  • Other – 24%

E.U. households
