Renewable energy is a term used to describe a variety of energy sources which do not have a finite supply. In contrast, energy sources such as coal, oil and gas are non-renewable forms of energy and will one day run out. In fact supplies of these fossil fuels are already severely depleted and we need to look carefully at other sources of energy for the future. Renewable energy sources also have a further advantage over traditional fuels as they do not have the same negative environmental impact caused by CO2 emissions.
There are five main types of renewable energy, namely solar power, wind power, hydropower, biomass energy and geothermal power.
Solar power is the name given for using the energy of the sun to provide electricity or to heat water. Both types can be used in both domestic and larger scale environments.
Wind power harnesses the power of the wind to provide electricity and the UK has the largest wind resource in Europe much more of which can yet be utilised.
Hydropower means using the power of water to make electricity or run machinery. This currently produces 2% of the UK’s electricity needs but has been used for hundreds of years in locations such as water mills.
Biomass is a collective term for all animal and plant material. Biomass energy is produced by burning or digesting some forms of these materials and the UK already has some of the largest examples of the use of biomass to generate electricity in Europe.
Geothermal power uses the heat of the earth to produce energy or its warm water for industry, agriculture, bathing or cleansing.
All of these are renewable energy sources and will not be depleted by continued use. Whilst all are in use much more of this renewable energy has yet to be harnessed.
