Hoover Dam, one of the most iconic hydroelectric facilities, stands as a testament to the potential of such infrastructure.

Turbines and Generators

As water flows from the reservoir, it passes through turbines. These turbines are designed to capture the energy of the flowing water, causing them to spin. This mechanical force is then transformed into electricity through the operation of generators. In 2020, hydropower generated over 300 terawatt-hours (TWh) of electricity in the United States, as reported by the U.S. Energy Information Administration, underlining its significant contribution to the nation’s power grid.

Hydro energy’s reliance on the simple but potent force of flowing water makes it a pivotal component of our sustainable energy future. It’s a prime example of how harnessing nature’s own power can lead us towards a cleaner and greener world.
