World electricity consumption

World electricity consumption is the total amount of electricity consumed by humanity per year. Electricity is generated in power stations since 1882 and consumtion increases strongly since. The table lists the countries which consume most and how this electricity is generated. Finally scenarios for possible future development are described.

Generation

Coal plant

After the invention of the steam turbine in 1883 world electricity consumption could increase strongly.

An electric generator can be driven by

• a steam or gas turbine in a thermal power plant
• or a hydraulic turbine in a hydropower plant
• or a windturbine, stand-alone or in farms.

Energy sources for electricity generation are usually classified as

• fossil, using coal, lignite, petroleum and natural gas,
• nuclear, using uranium,
• renewable, using hydropower, biomass, wind and solar energy, among others.

Coal and lignite are the biggest energy source for electricity generation.

Renewable means from inexhaustible sources, with responsible management of nature.

Electricity consumption is measured in TWh/a (Terawatt-hours per year, 1 TWh = 1,000,000,000 kWh). The table lists the top 37 electricity consuming countries, which use 19.000 TWh/a, i.e. 90% of the consumption of all more than 190 countries. The data are of 2012. The last column contains the number of millions of inhabitants.

Consumption per head

Total consumption (2nd column) divided by number of inhabitants (last column) gives a country's consumption per head. In W-Europe this is between 5 and 8 MWh/a. (1 MWh equals 1000 kWh.) In Scandivia, USA, Canada, Taiwan and S-Korea it is much more, in develloping countries much less. The worls average is 3 MWh/a. A very low consumption per head, as in Indonesia, means that many inhabitants are not connected to the electricity grid. The same applies to countries with many inhabitants like Bangladesh and Nigeria that are absent in the table.

Scenarios

In all scenarios increasing efficiency will result in less electricity needed for a given demand of power and light. But demand will increase strongly on account of

• growing economy in developing countries and
• electrification of transport and heating. Combustion engines are replaced by electric drive and for heating less gas and oil, and more electricity is used, if possible with heat pumps.
