Electricity Generation: electrical energy has to be made by conversion from some other form of energy
e.g. tidal generation-high & low tides occur twice daily
-tidal water movement can be used to turn aturbine

Electricity Generation: electrical energy has to be made by conversion from some other form of energy
e.g. thermal generation-water is heated to make steam-pressure builds & the steam can only escape by passing through a turbine-this turns the turbine

Electricity Generation: electrical energy has to be made by conversion from some other form of energy
e.g. Wind-the blades themselves act as a turbine to turn the middle of the generator to produce
electricitycalled wind turbines, not wind mills
