Sustainable Energy refers to a way we can use and generate energy that is more efficient and less harmful to the environment. Another way of explaining Sustainable Energy is that it will allow us to meet our present energy needs without compromising the ability of future generations to meet their own needs. We can do this by being more efficient in how we use energy in our daily lives and also by increasing the amount of energy that comes from renewable sources such as the wind, the sun, rivers and oceans.
The main sources of renewable energy are:
- the sun (solar energy).
- the wind.
- moving water (hydropower, wave and tidal energy).
- heat below the surface of the earth (geothermal energy).
- biomass (wood, waste, energy crops).
