World's Annual Energy Consumption
Civilization runs on 580 exajoules per year and counting/Collective & Conceptual
Global primary energy consumption reached approximately 580 exajoules in 2023, with fossil fuels still accounting for roughly 80% of the total. This works out to an average continuous power draw of about 18.4 terawatts for all of civilization: transportation, industry, heating, cooling, and that phone charger you leave plugged in 24/7. For perspective, the Sun delivers about 174 petawatts to Earth's upper atmosphere, so we use roughly 0.01% of the available solar energy.
Measurements
~18.4 TW; energy per year converted to average watts
~29,900 TWh/year ≈ ~3.4 TW average; electricity is ~52% of total energy use
~71.6 GJ per person per year; varies 10× between countries
~37.3 billion tonnes of CO2 from fossil fuels (2023); ~4.6 tonnes per person
