- Biomass Fuel: This fuel is obtained from plants or from animal waste. This includes straw, cow dung, sewage and even rubbish.
- Hydroelectric power: This uses the natural flow of water to turn water turbines to generate electricity.
- Solar heaters: This uses energy from the sun to heat water directly.
- Solar cells: These cells are used to transfer energy from the sun directly into electricity.
- Geothermal power: In some places, rocks under the ground are hot. Water can be heated by pumping it through the rocks.
- Wind turbines: Used to generate electricity from the wind. The wind turns the large blades and the blades turn a generator.
