A hydroelectric power plant generates electricity by using the energy of flowing water. Typically located near rivers or dams, these plants harness the movement of water to turn turbines, which then convert kinetic energy into electrical energy. This process is efficient and produces renewable energy without emitting greenhouse gases. The main components of a hydroelectric power plant include a dam, reservoir, turbines, and generators. Water stored in the reservoir is released through the dam, creating a flow that spins the turbines. This method of energy production is sustainable and can provide a significant portion of a region's electricity needs.
