How it works:
generator
•
A dam is built on a river creating a reservoir . Water in the reservoir collects behind the dam wall. Dam operators control the ow of water with a sluice gate . When released, the water pushes through a pipe (called a penstock ) beneath the water’s surface. This turns a turbine that then rotates a generator to produce electricity.
