1 of 6© Boardworks Ltd 2013 Energy Resources
2 of 6© Boardworks Ltd 2013 What are energy resources? An energy resource is anything that can be used to generate power for human use. There are two categories of energy resource: non-renewable energy resources will eventually run out – once used they cannot be used again. Examples are fossil fuels (coal, oil, natural gas) and nuclear fuels (uranium, plutonium). renewable energy resources can be replaced or regenerated and will never run out. Examples are wind, hydroelectricity and solar power.

4 of 6© Boardworks Ltd 2013 Wind turbines have large blades that capture the kinetic energy of the wind. How do wind turbines work? Wind turbines are a source of 'clean energy’ as they do not produce polluting waste. However, some people consider them to be noisy and an eyesore. There is also some concern that, if wind turbines are poorly located, they could kill migrating birds. This kinetic energy directly turns a turbine and generates electricity.

6 of 6© Boardworks Ltd 2013 How is tidal power used?
Our alternative energy resource is Wind Power. Using wind turbines, the wind blows the blades of the turbine round, which turns a generator to produce.
Without energy nothing happens.
