  1. Reasons for change

  2. Production of energy in former times

  3. 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.

  4. Situation today

  5. 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)

  6. year 1992 1996 2005 energy consumption electricity contingent 9172 PJ 17,6% 9686 PJ 17,3% 9173 PJ 20,4% Especially in Germany Final energy consumption in Germany

  7. Especially in Brandenburg Drinking water consumption in Brandenburg 101,6 litre per head By contrast 5 litre – Madagascar 25 litre - India 300 litre - USA

  15. Greenhouse effect

  16. 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

  17. Future prospects positive prospects negative prospects

  18. Negative prospects there will be huge problems for our environment

  19. Positive prospects the world and our environment could take a rest
