How much total energy \u2014 combining electricity, transport and heat \u2014 does the country consume each year? When comparing the total energy consumption of countries, the differences often reflect variations in population size. This allows you to compare specific countries you might be interested in, and measure progress against others. An efficient electrical system or device converts a larger proportion of input electrical energy into its desired output (e.g., light, motion, computation) and minimizes conversion into undesirable forms, primarily heat. First, it directly impacts operational costs for consumers and industries, as electricity bills are calculated based on kWh consumed. This is distinct from “power,” which is the rate at which energy is consumed or transferred.<\/p>\n<\/p>\n

This interactive chart shows per capita electricity generation per person. Globally, primary energy consumption has increased nearly every year for at least half a century. This interactive chart shows primary energy consumption country-by-country. We see that global energy consumption has increased nearly every year for more than half a century. This interactive chart shows how global energy consumption has been changing from year to year. It is based on historical estimates of primary energy consumption from Vaclav Smil, combined with updated figures from the Energy Institute Statistical Review of World Energy.1<\/p>\n<\/p>\n
The above-mentioned underestimation of hydro, wind and solar energy, compared to nuclear and fossil energy, applies also to Enerdata. Water and air flow energy that drives hydro and wind turbines, and sunlight that powers solar panels, are not taken as PE, which is set at the electric energy produced. The Gulf States and Russia are major energy exporters, due to their large petroleum and natural gas reserves.<\/p>\n<\/p>\n
