Did You Know?

The prime component of most hydroelectric systems is a dam. A high dam funnels water downward at high pressure to spin turbines, which in turn drive generators to produce high-voltage electricity. Mountainous countries with rushing rivers can produce the most hydroelectricity. Though hydroelectricity comes from a clean and completely renewable energy source, dams disrupt natural systems in a way that disturbs environmentalists.
