- - - - These power plants use the kinetic energy of the wing to move the blades of a rotor at the top of a tower, this is referred to as the wind turbine
    - - Photo-thermal power plants
      - Photovoltaic power plants
    - - These plants use the heat found at deep levels in the earth. This heat may reach the surface in the form of steam, gases or hot water
    - - Forestry and agricultural waste
      - Specific crops, such as sunflowers and sugar beet
      - Waste from agri-food industries.
    - - The mechanical energy from the tides.
      - The mechanical energy from the waves.
      - The energy from the ocean's thermal gradient
- - - - The turbine converts mechanical energy into the rotating movement of a shaft
      - An alternator has a fixed part, called a stator, and a moving part, called a rotor, connected to the turbine shaft
  - - - Increasing the voltage to prevent significant energy loss
      - Transporting it by high voltage cables attached to towers
      - Decreasing the voltage at the electricity substations to 3-30kV
      - Distribution to homes, offices, industries and public facilities
