​

Answer 1

Wind Power
Turbines use wind to generate electricity without creating pollutants.
Currently, this is one of the least expensive alternative fuel sources available.

Solar Power
Thee solar cells turn sunlight into electricity directly, so there is no need for a generator. It is a clean, non-polluting source of energy.

Biomass
This is the use of plant matter and animal waste to create electricity. When converted properly, it is a low-carbon source of energy with little pollution.

Geothermal Energy
This is the use of heated water and steam from the Earth to run power stations, which turn the steam into electricity.

Hydroelectric Power
This uses flowing water to move turbines which generate electricity. Hydropower provides 20 percent of the world’s energy needs.
