Solar power
- Photovoltaic cells convert energy from the sun’s rays into electricity.
- Photovoltaic cells can be used in solar farms where lots of sheets gather electricity or on a smaller scale on private houses.
- They are expensive to set up, however they need little maintenance.
- They can be used in remote locations providing power.

Tidal power
Tidal power
- The movement of turbines in the water use a generator to convert movement from the tide or waves into electricity.
- It is a very consistent and predictable form of renewable energy

Hydro-electrical power (HEP)
Hydro-electrical power (HEP)
- A reservoir of water is created with a dam. The dam controls the flow of water out of the reservoir.
- As the water flows out of the reservoir, it turns turbines that use a generator to convert movement into electricity.
- The reservoir is refilled when it rains or when the water can be pumped back in. This flow of water can be increased on demand.

Biomass
Biomass
- Waste material from animals and plants contains stored energy from the sun.
- The biofuel is burnt to generate heat and power turbines that generate electricity.

Disadvantages biomass
Disadvantages biomass
- Burning biomass creates carbon emissions.
- Biomass crops can be farmed which needs areas of land. This results in:
- Deforestation, which can disturb or harm wildlife.
- Less food crops being grown in areas where food may be scarce.
- Water being used to feed crops in areas where water may be scarce.
