Renewable energy comes from sources that may be continuously renewed by nature. Consequently, we will never be running out of these energy sources, that is, for as long the Sun’s nuclear fusion processes continue to provide the Earth with energy.
Here are a few examples:
Solar Power: Solar power is seen as renewable energy as expectations are that nuclear fusion processes that are powering the Sun will continue to generate sunlight for billions of years.
We are capturing the light of the Sun to:
- Drive steam turbines to produce electricity (the concentration of Solar Power),
- Heat homes (via so-called Passive Solar Design or via an Active Solar Heating System),
- Make hot water (via an Active or Passive Solar Hot Water System),
- Cook (on a Solar Oven),
- Distill water
- Generate electricity by using solar electric (or photovoltaic) cells
