What is Hydropower?

Hydropower is a renewable energy source that harnesses the energy of flowing or falling water to generate electricity. It is one of the oldest and most widely used forms of renewable energy, dating back to ancient civilizations.

How Hydropower Works

Hydropower plants harness the energy of flowing water to generate electricity. This is typically done by building a dam to create a reservoir, which stores water. When the water is released from the reservoir, it flows through turbines, which are connected to generators. The force of the flowing water spins the turbines, which in turn, generate electricity.

Benefits of Hydropower

• Renewable: Hydropower is a renewable energy source, as the water cycle ensures a constant supply of water.
• Low Greenhouse Gas Emissions: It produces minimal greenhouse gas emissions compared to fossil fuels.
• Reliable: Hydropower plants can generate electricity consistently, providing a reliable source of energy.
• Flood Control: Dams built for hydropower can help to control flooding in certain areas.
• Water Supply: Hydropower reservoirs can also be used for water supply, irrigation, and recreation.
