Steam



         Steam is the gaseous phase of water. This steam is an im-

         portant part in electrical generation since it can be used to

         spin a turbine (which is connected to a generator to create

         power).

         Tidal energy



         This is the form of energy got from water tides on the sea

         shores.

         Tides are periodic rises and falls of large bodies of water.


         The tides are caused by gravitational interaction between the

         earth and the moon.
