Reasons for change

Production of energy in former times
![Page 3: Reasons for change](https://reader036.fdocuments.net/reader036/viewer/2022081603/568134ec550346895d9c2a58/html5/thumbnails/3.jpg)
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
![Page 6: Reasons for change](https://reader036.fdocuments.net/reader036/viewer/2022081603/568134ec550346895d9c2a58/html5/thumbnails/6.jpg)
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

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

Climate change
Climate change factors
- Emission of greenhouse gases greenhouse effect
- Combustion of fossil fuels carbon dioxide- Deforestation virgin forest, rainforest

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

Positive prospects
the world and
our environment
could take a rest
