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 expensive.

WIND: wind turbines (modern windmills) turn wind energy into electricity.

Advantages: potentially infinite energy supply.

Disadvantages: manufacture and implementation of wind farms xan be costly.

TIDAL: the movement of sea water in and out drives turbines.

Advantages: a lot of energy is generate this way.

Disadvantages: construction can be costly.

GEOTHERMAL: it is possible to use heat froma under the earth's surface in volcanic regions. Steam can be used for heating or tu power turbines creating electricity.

Advantages: potentially infinite energy supply.

Disadvantages: only works in areas of volcanic activity.

HYDRO - ELECTRIC - POWER (HEP): energy harnessed from the movement of water thorough rivers, lakes and dams.

Advantages: creates water reserves as well as energy supplies.

Disadvantages: They can cause the flooding of surrounding communities and landscapes.

BIOMASA: an organic material which can be burnt to provide energy (heat or electricity)

Advantages: it's a cheap source of energy.

Disadvantages: when burnt, it gives of atmospheric pollutants, including greenhouse gases.
