World Commercial Energy Consumption by Region= produced for sale rather than for direct use (made by fossil fuels)Consumption of energy concentrates in industrialized nations. Why?

World energy consumption

World energy consumption

This chart indicates the breakdown of contributions of the fossil fuels, “traditional” renewables such as firewood, and “new” renewables such as solar power, to the total global energy supply in the 1995.

The domination of fossil fuels over the large nuclear reserves, and undeveloped new renewables, is immediately apparent.

World energy consumption/capita

Primary energy consumption

World energy demand

World energy demand

Reasons:

Population growth e.g. population boom after WWII, better health

care in developing countries

Economic growth e.g. increased use of cars, higher industrial

production

Lifestyle changes e.g. more consumer electronics used
