All use generators to produce electrical current
No. A hydroelectric plant uses falling water to turn water turbines attached to electric generators.
They are usually located near natural fast flowing rivers, like Niagara Falls, or man made dams, like the Hoover Dam in the US, or Three Gorges Dam in China. But one thing they have in common is that hydroelectric plants need water to turn turbines to generate electricity.
Turbines. These are then used to spin magnets next to wires. This generates electricity.

Hydroelectric power plants convert GPE into electric energy. When the water flows from the higher point to the lower point, hydroelectric turbines convert the energy of the flowing water into energy.
They both generate electricity.
Hydroelectric plants use the running water by a turbine with blades on it, and when the water flows through these turbines they rotate,. in turn rotating the alternators that make the electricity which is sent from the power-station via the wires to houses, businesses etc that need the electricity.
Turbines are linked to the generators on a common shaft. The turbines are turned by steam (in the case of nuclear, coal, or biomass power plants), by water (in the case of hydroelectric power plants), or by wind (windmills). The turbine then turns the generator, which creates electricity. Think of blowing on a fan. Your "wind" is turning the blades. Now, if that were attached to a generator, you would be creating electricity. (Of course, you'd have to blow REALLY hard...)
Mavel is a Czech - American company that is one of the premier international engineering and manufacturing companies that provides hydro turbines for small hydroelectric power plants worldwide.
hydro power is practically always constant wind power might not be there at all sometimes and it could be a load as opposed to a source.
