Hydropower is significant because it provides a clean and sustainable source of energy that can help reduce reliance on fossil fuels, contributing to lower greenhouse gas emissions and promoting environmental sustainability.

The Basics of Hydropower

Hydropower refers to the generation of electricity using the kinetic and potential energy of flowing water. Typically, it involves the construction of hydroelectric power stations where water is stored in dams. As water is released, gravity causes it to flow down, turning turbines that generate electricity. The efficiency of this process makes hydropower one of the most effective forms of renewable energy available today.
