About ... Most Energy Efficient Countries

Zeynep Kahraman, TSP team


The energy efficiency is the ratio of gross domestic product measured in constant US $ at market exchange rates or purchasing power parities over primary energy consumption and is often used as an index to measure the energy conservation of a country which includes technological and behavioral factors.

Data Source:

 Historical Energy Consumption statistics:

Context and definitions

Total primary energy consumption reported in this table includes the consumption of petroleum, dry natural gas, coal, and net nuclear, hydroelectric, and non-hydroelectric renewable electricity. Total primary energy consumption for each country also includes net electricity imports (electricity imports minus electricity exports).

Individual energy efficiencies are calculated by dividing the gross domestic market exchange rates in billions of (2005) U.S. dollars and purchasing power parities in billions of (2005) U.S. dollars data from United Nations Statistics Division by the primary energy consumption data in Mtoe (TSP calculation see: Primary Energy Consumption Statistics)  for each available country and year.
