2 of 7© Boardworks Ltd 2008 What are renewable energy sources? Renewable energy resources will not run out because they can easily be generated anew. The photograph shows a dam built for the generation of hydroelectric power. Other examples of renewable energy resources are: wind power solar power tidal power biomass
3 of 7© Boardworks Ltd 2008 How can the wind generate electricity?
4 of 7© Boardworks Ltd 2008 There are a number of methods of generating electricity from the Sun’s energy. Solar panels convert sunlight into electricity directly. They are used on some new houses and also on calculators. Mirrors can be used to focus sunlight onto pipes containing water. The hot water drives a generator. How is solar energy used? Passive solar heaters heat water directly using sunlight. Why are they black?
5 of 7© Boardworks Ltd 2008 Other renewable energy sources What other forms of renewable energy are there? Geothermal energy uses heat stored beneath the Earth’s surface to create steam. This is then used to power turbines. Biomass fuels are made of processed plant remains and are used in the same way as fossil fuels. More crops are grown to replace those used. Tidal currents can be used to generate electricity. The moving water is forced through turbines, which generate electricity. Waves can generate electricity by causing buoys to rise and fall. This kinetic energy is converted to electrical energy.

Renewable Forms of Energy (Also called Alternative Energy or Sustainable Energy)
Alternative energy 5 th grade Science. Hydroelectricity Uses moving water to turn the turbines of a generator to create electricity Hydro- water Electricity-
Wind energy – energy generated from the movement of air Wind moves through a wind turbine which turns an electric generator converting.
Energy Resources Nonrenewable.
