Gravity and an electrical motor (generator)
The hydroelectric generator made 5 megawatts of electricity every day.
do you gyus no if you need electricty to make hydroelectricity
They are used together to make hydroelectricity.
Hydroelectricity is generated through the action of water. Water flow will turn the shaft of a generator which produces a clean and renewable flow of electricity.

To tap hydroelectricity, there must be a dam which can store water and let it flow rapidly through a sink hole. The pressure of the falling water can drive generator turbines and these will generate electricity.
It can and is. In my country (Faroe Islands) , whole villages are being powered by hydroelectricity. I've never heard of a house having a private generator, though, if that's what you're asking.
This is called hydroelectric power, or hydro power.
Near dammed rivers, although it will be difficult to assure that some current flow does not derive from even a very distant hydroelectric generator.
I guess you mean wave energy. When the stream of a river is streaming through a dam, it runs a turbine and which drives a generator, which produces energy.
they are important as they provide many medicinal herbs and hydroelectricity
