What is Renewable Energy? Renewable sources of energy are those which are continuously available in our environment as defined: 'Energy flows derived from natural forces that are continuously at work in the earth's environment, and which are not depleted by being used'.

 

Most renewable energy sources are derived from solar radiation. These include the direct use of solar energy for electricity generation or heating. There are indirect forms too, such as energy from the wind, waves, the flow of water and from plants and animals (i.e. straw, wood, dung, etc.). Other energy sources such as geothermal, tidal and energy from waste are also considered to be renewable, although the energy generated comes from sources other than solar radiation.

 

Why should we use it? All over the world - and in particular the developed nations - we are consuming energy in ever increasing quantities. We use energy in every aspect of daily life from providing warmth and light, to transportation for work and pleasure.

 

To generate these vast amounts of energy we have until now depended largely on burning fossil fuels - primarily coal, oil and gas. The bad news is that these are finite resources which have taken millions of years to form. Furthermore, they also release large amounts of carbon dioxide (CO2) into the atmosphere when burnt to provide energy.

 

In contrast, renewable energy sources either emit no greenhouse gases, or they are carbon neutral over their life-cycle (e.g. crops used as biomass fuel only emit the same amount of CO2 as they absorb when growing). Using renewables can help the environment by reducing our reliance on fossil fuels, adding to the diversity and security of future energy supply, cutting energy imports and contributing to national and international targets on emissions reduction.
