How It Works

  1. A dam blocks water from moving where it wants to naturally
  2. Instead, the water flows through a pipe to a turbine, then back out on the other side of the dam
  3. Turbines spin by force of water and rotate a generator
  4. The generator produces electricity and sends to power lines, bringing electricity to homes and businesses
