Introduction.


   CLEARLY, WE NEED MORE INCENTIVES TO QUICKLY INCREASE THE USE OF
  WIND AND SOLAR POWER; THEY WILL CUT COSTS, INCREASE OUR ENERGY
       INDEPENDENCE AND OUR NATIONAL SECURITY AND REDUCE THE
                 CONSEQUENCES OF GLOBAL WARMING.

   During the 1900s, regulations requiring an approach to “zero

emissions” from vehicles increased interest in new battery technology.

Battery systems that offer higher energy destiny became the subject of

joint research by federal and auto industry scientists.


   Solar Cars have been around for a while, but mostly as novelties or

the products of futuristic science competitions. Knowledge gained from

this is now being put to broader use as populations try to wean

themselves from fossil fuels. Consumers are looking for alternatives

and, as photovoltaic cells become more efficient, solar cars are

creeping into the market place.

             WHAT IS

What is Solar Energy?

   The Solar Energy is the energy received by the earth from the sun.

This energy is in the form of solar radiation, which makes the

production of solar electricity possible.


   Solar energy is vital to support life on earth, it helps to grow our

food, light our days, influence weather patterns, provide heat, and can

be used to generate solar electricity.


                                                   Solar electricity on man-

                                             made devices such as solar

                                             panels or solar   cells in order

                                             to provide a source of clean,

                                             and low cost of renewable

                                             energy.

Solar energy?

We have used energy from the sun to provide electricity for many

years, in the form of solar cell calculators and other small, low energy

consuming devices.


      As solar energy technologies become more advanced, we are

able to exploit the energy we receive from the sun to provide a

greater, significant amount of our electricity.


      Without solar energy, human life couldn’t be supported on planet

earth due to many different factors.

   Over the past decade, the cost of making electricity has risen for

coal, natural gas, and oil due to decreasing supply and the incalculable

damage done to the environment that are never included in energy cost
