The other options are incorrect because:

  • Solar power is a type of renewable energy that uses the sun’s energy to generate electricity.
  • Wind power is a type of renewable energy that uses the wind’s energy to generate electricity.
  • Nuclear power is a type of energy that uses the heat from nuclear fission to generate electricity.
