What is renewable energy?

Renewable energy is generated from natural resources, which are replenished continuously. This can mean for example,sunlight, wind, rain, geothermal heat, and tides.

Renewable energy sources:

  • Solar power
  • Wind power

  • Geothermal
  • Bioenergy

Out of these solar and wind power are two of the most widely used forms of renewable energy. Yet, all of them have a role in the economy we live in.
