Why Renewable Energy?
Most electricity is currently generated at power stations by burning fossil fuels such as coal, gas and oil. We are consuming our natural fossil fuel resources very rapidly, and they will eventually run out. We need to look at alternative ways of producing energy using renewable sources which do not produce CO2.
Renewable energy is energy which is generated from sustainable sources, for example wind, solar, hydroelectric, tidal, wave, ground source heat pump, and geothermal. Traditional nuclear energy generation is not renewable.
There are several reasons (economic, political, and environmental) why current energy supplies are not totally secure. When a country’s fuel supply is exhausted, it may become dependent on other countries. Political and economical differences may dictate the cost and availability of this energy. Renewable energy allows independent energy generation.
We need to use less energy to make our remaining fossil fuel supplies
last longer, since they are also essential for the manufacture of many
plastics, chemicals and medicines. We need to change our behaviour and
attitudes towards our energy usage.
