Why do you need water to make electricity?

Answer 1

Discounting solar and wind generation. It depends on how you are generating electricity. For example, in your car, you are generating electricity as the engine turns which also turns a generator or alternator to recharge your battery. In a car with a water cooled engine, water cools the engine so it doesn't overheat. In some power generation water is heated to produce steam which in turn might turn a turbine to generate electricity. In other cases a hydroelectric system might use falling water to turn a turbine. In a nuclear power plant water can be used to cool the heat generated by the nuclear fission process.

Answer 2

Water is used in various ways to generate electricity, such as in hydropower plants where the energy of flowing water is used to turn turbines that generate electricity. Water is crucial as it provides the force necessary to turn the turbines, which in turn produce electricity. Additionally, water is used for cooling purposes in many types of power plants, including nuclear and traditional thermal power plants, to dissipate heat generated during the electricity generation process.
