Water wheels or turbines turning generators.
Usually the water will turn some wheels or turbine; this will then turn a generator, which generates the electricity.
Energy is actually not created. Hydel power plant converts the stored water's potential into Kinetic energy energy in the runneer & at last to electrical energy through Generator
Electrical energy can be generated from falling water by using a hydroelectric power plant. The potential energy of the water is converted into kinetic energy as it falls, which turns a turbine connected to a generator. The generator then converts the kinetic energy into electrical energy.
Hydro-electric
To separate water into hydrogen and oxygen, electrolysis is usually used; this uses electrical energy. Of course, the electrical energy can be generated in any of several ways.
Hydropower is the energy produced by running water. It is generated by harnessing the gravitational force of flowing or falling water to turn turbines connected to generators, producing electricity.
Water flowing through a turbine which is connected to an electric generator converts the water power to electrical energy. Electrical energy generated this way is known as hydroelecticity to differentiate it from electrical energy generated by other means, such as wind power, solar power, fossil fuels or nuclear fuels.
Hydropower energy is generated by capturing the energy from flowing water in a river or dam. This energy is converted into electricity through turbines connected to generators. Hydropower is a renewable energy source that is clean and sustainable.
The energy transformation in running water involves potential energy being converted to kinetic energy as the water flows downhill or over a waterfall. This kinetic energy can then be harnessed and converted into electrical energy using technologies like hydroelectric power plants.
Turbines in a hydroelectric dam convert mechanical energy (from flowing water) into electrical energy. When water flows through the turbines, it causes them to spin, activating a generator that produces electricity.
Anything that moves has kinetic energy. Water may also have potential energy - if it is at a higher level and you have the possibility of making it fall down. And running water can be used to make electrical energy.
Electric energy generated from a water source is typically known as hydroelectric energy.
