How Does It Work?

Hydro energy harnesses the power of moving water to generate electricity. This is typically done using hydroelectric dams, where water flows through turbines, spinning them to produce mechanical energy. This energy is then converted into electricity by generators within the system. The process is highly efficient, with modern plants capable of converting over 90% of available energy into usable electricity.

Modern hydroelectric plants include pumped storage systems, which store energy by pumping water uphill during low-demand periods and releasing it to generate electricity during peak demand. Run-of-river systems and small-scale hydro solutions are also gaining traction as environmentally friendly alternatives.

Advantages of Hydro Energy
