Energy and fuels Environmental impacts World energy consumption Mgr. Matúš Dobeš, 2005

Environmental impacts of energy production

Coal-fired power plant

Environmental impacts Coal Air pollution caused by burning (CO 2 )

Environmental impacts Natural landscape distortion by coal mines

Environmental impacts Oil Air pollution caused by burning (CO 2 ) An oil power plant in Iraq

World energy consumption

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

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 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

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
