What is renewable energy?
Renewable is energy derived from natural sources that are replenished at a higher rate than they are consumed. Sunlight and wind, for example, are such sources that are constantly being replenished.
Renewable energy sources are plentiful and all around us.
Hydropower harnesses the energy of water moving from higher to lower elevations. It can be generated from resevoirs and rivers. Hydropower or waterpower is the cheapest energy source.
Solar panels absorb and use the energy from the sun to create new energy. They are placed everywhere such as on roofs as wells as on fields.
Wind mills use wind to create energy with their big wings. They have big turbines that allow us to take this wind and turn it into energy. It is a very clean way to get energy.
The Global Wind energy outlook projects that by 2030 wind energy will offset 2,5 billion tons per year of carbon.
