Fwd: WHEN SOLAR ENERGY IS STORED, IN WHAT FORMS CAN BE USED?

Solar energy comes from the sun; it is produced by nuclear reactions
that occur inside the sun. Solar energy is stored in precipitation, wind
and ocean currents. The precipitation that falls into the river produces
energy from the moving water; this energy is collected by hydroelectric
power stations. Wind farms are made in areas where the wind is strong
and constantly occurring so that they produce electricity.

Solar energy is stored in plants and animals, it can therefore be used
as: firewood (where it is burned to produce heat energy in the form of
fire) or as in the case of beet, maize, sugar cane it can be used to
make alcohol through the process of fermentation. This process is very
similar to the petrol. Petrol is made from plant fossils and fuels have
solar energy that has been stored in the earth for millions of years
ago.

  • Does not say much and certainly does not answer your question that you pose.

    Your reference is a kidies page that actually describes COAL -- A Fossil Fuel - I think you inserted the wrong reference!!!!!!!

    Need to be more discerning and precise!
