What type of energy is required for both wind power and hydroelectric to work?

Both wind power and hydroelectric power harness the kinetic energy of moving air and water, respectively, to generate electricity. In wind power, the movement of air (wind) is captured by wind turbines, which convert this kinetic energy into mechanical energy. This mechanical energy is then used to rotate a generator, which produces electricity.

Similarly, in hydroelectric power, the kinetic energy of flowing water (hydro) is captured by turbines or water wheels. As water flows through the turbine blades or impinges on the water wheel, it causes these components to rotate. The rotational energy is then converted into mechanical energy, which is used to spin a generator and generate electricity.

In both cases, the kinetic energy of the moving air or water is the primary energy source that drives these renewable power generation methods.
