Water power (hydro electricity)
- Water is used to drive turbines to produce electricity
- Underused in this country
- Generates 20% of the world's power
- But only 2% of UK's electricity
- Almost 200 hydro electric plants in UK - most in Scotland
- Campaigners say hydro electricity is greener because water can be stored behind dams and used to create electricity when needed most.
