Energy - Coggle Diagram

- - - - these power plants use the kinetic energy uf the wind to move the blades of a rotor at the top of a tower, this is referred to as the wind turbine.
      - Wind farms are a clean form of generating electnmty However, they can only be instafled in plat.es with appropnate wind conditions.
  - - - Geothermal energy may be used directly —for hot water and heating, industnal use and so on — and indirectly —the heat generates steam, which produces electricity.
  - - - Forestry and agricultural waste
      - specific crops, such as sunflowers and cougar beet.
      - waste from agri-food industries.
  - - - The mechanical energy from thetides
      - The mechanical energy from the waves
      - The energy from the ocean's thermal gradient
- - - - his type of plant tm.ludes a nuclear fission reactor that produr.es the pressunsed steam needed to move the turbme rotor.
      - Uranium ts the main fuel used.
  - - - Efectnctty ts generated as a result of two combined cycles, a cycle that uses air and gas, and a conventional thermal cycle Dunng the first cycle, a gas turbine is used that includes a compressor
      - ir is mixed with the gas and is burnt, which generates electncity in the turbine-alternator system. The combustion gases are transported to a boiler, where they transfer their energy to the water dunng the second cycle
  - - - Depending on the destination of the water, hydraulic power plants are divided into two types, gravity or pump.
- - - - • An a lternator has a fixed part, called a stator, and a moving part, called a rotor, connected to the turbine shaft.
      - As the rotor shah moves, alternating electrical current is produced on each of the stator's coils.
  - - - • Inc reasing the voltage to 220 000 V or 400 000 V to preventsignif«.ant energy loss, due to the Joule effect
      - Tr a nsporting it by high voltage cable~ attached to towers
      - • Dec reasing the voltage at the electncity substations to 3-30 kV
      - D i stnbution to homes, offices, industnes and public faolities Dunn this srage, the voltage is reduced to 230-400 V.
