Energy Production and Consumption

The availability of energy has transformed the course of humanity over the last few centuries. Not only have new sources of energy been unlocked – first fossil fuels, followed by a diversification to nuclear, hydropower and now other renewable technologies – but also in the quantity we can produce and consume.

This article focuses on the quantity of energy we consume – looking at total energy and electricity consumption; how countries compare when we look at this per person; and how energy consumption is changing over time.

In our pages on the Energy Mix and Electricity Mix we look in more detail at what sources provide this energy.

In the energy domain, there are many different units thrown around – joules, exajoules, million tonnes of oil equivalents, barrel equivalents, British thermal units, terawatt-hours, to name a few. This can be confusing, and make comparisons difficult. So at Our World in Data we try to maintain consistency by converting all energy data to watt-hours. We do this to compare energy data across different metrics and sources.
