Reasons for change

Production of energy in former times

In former times humans made use of nature. For instance, they applied horses in order to plough fields. Back then water power was used by water wheels and wind energy by windmills. As for heating they employed fire wood in contrast to the use of oil or gas nowadays.

Situation today

Rising consumption Causes

- Growth of population ( rising energy consumption)- Mechanisation (e.g. electronic equipment in households)- Low energy efficiency of electronic equipments

( needless energy consumption)- Waste of energy- Increasing number

of emerging markets (none

environmentally friendly

energy production)

Especially in Germany

Climate change

Climate change factors

- Emission of greenhouse gases greenhouse effect

- Combustion of fossil fuels carbon dioxide- Deforestation virgin forest, rainforest

Greenhouse effect

Consequences

Temperature rise

- Deglaciation of polar caps, glaciers- Increase of sea level- Displacement of climes- Drinking water crisis- Increase of extreme

weather (flood waves, storms…)- Change of sea currents
