Renewable energy sources like the Sun, Wind, waves and the heat of the earth are also used to make electricity.
Renewable sources can be used again and should not run out.
Renewable sources are either carbon neutral or do not produce greenhouses gases so are much less harmful to the environment.
1 – Which energy sources are renewable or non- renewable?
A – Biomass uses the energy from plants and waste materials to make electricity. For example, wood or animal droppings can be burnt to make steam that turns turbines to make electricity.
B – Wind is made when the sun heats the Earth and the area above land gets hotter than the area above water. The hot air above land rises upwards leaving an area of low pressure. Cooler air moves into this area of low pressure making wind which we use to turn wind turbines and make electricity. Wind used to be turn windmills to grind wheat into flour.
2 – Write if the energy sources are renewable or non-renewable.
Hydro-electric
Oil
Solar
Wind
Natural gas
Biomass
Coal
Wave
Nuclear
Tidal
Geothermal
Keywords:
A - Renewable source of energy
B - Renewable source of energy
2 - Non- renewable: oil, natural gas, coal and nuclear.
Renewable: hydro-electric, solar, wind, biomass, wave, geothermal and tidal.
