Respuesta :

The two type of alternative energy sources are tidal power and wind turbines.

Electricity is defined as the flow of charges which can be gotten from various sources that include:

  • coal,
  • natural gas,
  • oil,and
  • nuclear power.

Alternative to energy are those renewable energy sources that can generate electricity. Example are

  • wind and
  • water

Wind turbines uses wind with the help of gravity to generate electricity. The wind pushes against the blades making them turn which exerts force of gravity into the turbine to generate electricity.

Tidal power uses waves with the help of gravity to generate electricity. Electricity is generated from the gravitational pull of the sun and earth's rotational pulls that causes water waves to occur.
