What is the process of hydroelectric power generation?

• The process of hydroelectric power generation involves using a dam to create a reservoir, releasing water to flow through turbines connected to generators, and transmitting the generated electricity to consumers.

• The process of hydroelectric power generation involves using wind turbines to convert wind energy into electricity.

• The process of hydroelectric power generation involves harnessing the energy from the sun to generate electricity.

• The process of hydroelectric power generation involves burning fossil fuels to produce steam, which then turns a turbine connected to a generator.
