GDP per unit of energy use (PPP $ per kg of oil equivalent)

This indicator measures the efficiency of an economy in generating output relative to its energy consumption by expressing gross domestic product in terms of purchasing power parity (PPP) per kilogram of oil equivalent. By converting GDP into current international dollars grounded in 2017 International Comparison Program data, this metric allows for meaningful cross-country comparisons of economic productivity against energy expenditure. An international dollar ensures that the purchasing power is consistent across different nations, facilitating a better understanding of how well economies utilize energy resources. A higher value indicates greater efficiency, suggesting that a country can produce more economic output for each unit of energy consumed, which can be indicative of advancements in technology, improved energy practices, or a shift toward less energy-intensive industries.
