   1. Solar energy can produce electricity through the use of photovoltaic cells.
   This energy often is used to
   -heat water
   -operate small electronic devices

   But the main use of solar power is, of course, growing plants. (Without the sun, nothing could live!)

   Solar energy is used as follows:

   It heats and lights the earth, without it we would all die on a very cold rock with no plant life.

   Photo voltaic cells can collect solar energy and produce an electric current.

   Solar collectors, usually roof mounted, are used domestically to heat water in homes.

   Some desert areas use an array of mirrors to heat water in a central tower to produce steam to turn a generator and produce electricity.
