Conventional Energy Sources �have been widely used for many years

RENEWABLE

NON-RENEWABLE

can be used �indefinitely without �running out

resource will �eventually be �used up

resource is replenished by a natural process

does not renew naturally; �the resource is finite

(limited supply)

Hydroelectric Energy

  • the downhill flow of the �water can occur naturally �or can be created by �building a dam that �holds water
  • water flows past a turbine�and causes it to turn
    • the rotation of the turbine generates electricity that is transferred to the power grid via power lines
