Energy security describes access to reliable and affordable sources of energy.

Countries like Russia and Canada, with surplus energy, are energy secure. Those with an energy deficit, like the USA, suffer energy insecurity.

Some countries produce a lot of energy and some produce very little. Energy production is relative to the amount of resource available and the money available to exploit it.

The largest producers of energy are Russia, China and the United States. These countries produce energy from predominantly non-renewable resources such as oil, natural gas and coal.

There is a link between GDP and energy consumption, with developed countries using more energy than developing countries.

The map shows energy consumption in different countries.
