  2. Definition of Hydroelectricity • Hydroelectricity comes from a hydroelectric dam it makes power.

  3. . • The hydroelectric dam creates power by damming a lake or river. The water is held back a little bit. Some of the water travels down a pipe and through a turbine witch turns a shaft witch turns a generator creating power.
