What is hydroelectric power? Hydroelectric power is the electricity that is generated from the kinetic energy of moving water. Currently, only about 1% of the UK’s electricity is from hydroelectric power.

How is hydroelectricity produced? Build a dam across the end of a river valley to form a reservoir. This can be done high up in mountainous areas. Hydroelectric is a reliable source of electricity and can be started quickly. This is the Glen Canyon dam in Arizona, USA.

How is hydroelectricity used effectively? Large-scale hydroelectric power stations must be sited in high, mountainous areas. Flooding river valleys destroys local villages and houses. Hydroelectric power schemes also cost a lot of money and take a long time to build. However, they do last a long time and are a reliable source of large amounts of electricity. In the UK, hydroelectricity is generated in Scotland North Wales.

Pros and cons of hydroelectric power

What is wave power? Wave power captures the kinetic energy of the oceans and converts it into electricity. Wave power is actually a form of solar energy that is transferred to water by the wind.

The ‘Limpet’ (Land-Installed Marine-Powered Energy Transformer) on Islay, Scotland. The low profile of this shoreline unit is designed so that it does not affect coastal views.

How does wave power work?

How else can wave power be used? A deep-water device tested in Orkney, Scotland is the Pelamis Wave Energy Converter. direction of waves ducks move up and down Another proposed machine is Salter’s duck, which could use wave power efficiently. What are the advantages and disadvantages of wave power?

Wave power – true or false?

What is tidal power? Tidal power flows twice a day mainly due to the pull of gravity from the moon. A river estuary is dammed. Water is only able to flow in and out through turbines. Tidal power provides lots of electricity but construction is expensive and wildlife habitats are destroyed.

How is tidal power used?

How can tidal power be used effectively? Tidal power is a predictable and reliable source of electricity. The difference between high and low tides needs to be at least 5 metres to be economic. Monthly variations in the height of the tide also affect how much electricity is produced. Tidal power only produces electricity when the tide flows, about 10 hours a day, and should be used with other sources.
