Renawable table:

1-E: Solar :

Energy from sunlight is captured in solar panels and converted into electricity. Advantages: Potentially infinite energy supply. Disadvantages: Manufacture and implementation of solar panels can be costly.

2-A: Wind:

Wind turbines(modern windmills) turn wind energy into electricity. Advantages: Potentially infinite energy supply. Disadvantages: Manufacture and implementation of wind farms can be costly.

3-F: Tidel:

The movement of sea water in and out drives turbines. Advatages: a lot of energy is generated this way. Disadvantages: Construction can be costly.


4-B: Geothermal:

It is possible to use heat from under the earth´s surface in volcanic regions. Steam can be used for heating or to power turbines creating electricity. Advantages: Potentially infinite energy supply. It is used successfully in some countries, such as New Zeland. Disadvantages: Can be expensive to set up. Only works in areas of volcanic activity.

5-C: Hydro-electric-power(HEP):

Energy harnessed from the movement of water through rivers, laks and dams. Advantages: Creates water reserves as well as energy supplies. Disadvantages: Costly to build. They can cause the flooding of surrounding communities and landscapes. Dams have major ecological impacts.

6-D: Biomasa:

An organic material which can be burnt to provide energy (heat or electricity). Advantages: It is a cheap source of energy. Disadvantages: When bunt, it gives off atmospheric pollutants ,including greenhouse gases.
