A: Hydropower works in a series of steps: • Water is stored in a reservoir, usually behind a dam. • When released, the water flows due to gravity, creating kinetic energy. • This flowing water turns turbines connected to generators. • As the turbines spin, the generators convert the kinetic energy into electricity.
How does it work? Basically, there are several ways hydropower technologies can generate electricity. You may recognize dams like this one. The word "Impoundment" appears onscreen with an image of a dam, moving from the exterior to the interior. This technology is called an impoundment. The impoundment stores water in a reservoir.

Humans have used water power for centuries. But we didn't start making hydropower—electricity from our rivers, streams, and lakes—until just over 100 years ago, not too long after Thomas Edison invented electric power. Today, instead of using large, wooden wheels, we use propeller-like devices called turbines, which spin as water rushes through the...
Most of the country's hydropower facilities were built in lakes, streams, and rivers decades ago. They often used large dams that block the water's flow, creating a pool of water above the structure. One or more pipes give that pooled water a path to surge downhill. And as the water rushes through those pipes, it spins a turbine, which runs a gener...
Hydropower costs less than most other energy sources, making it an affordable source of renewable energy. Except during periods of extreme drought, we can count on water to flow day and night and all year round. And this consistency is critical if we want to rely purely on clean energy sources, such as solar energy and wind power, which can come an...
Water housed in hydropower facilities can be used to water crops, put out wildfires, or provide clean drinking water to local communities. In some areas, such as the drier Western states, the warming climate is likely to cause more droughts, which could threaten water supplies. Because hydropower facilities can absorb and store extra water, they ca...

Step Four: Transmission to the Grid. The electricity generated by the generator is sent through a transformer, which steps up the voltage to make it more efficient for long-distance transmission. The power is then sent to the grid for distribution to homes, businesses, and other consumers.
