We often hear about solar
cars, solar heating, and solar
batteries. But will solar energy ever
be a major source of energy for
society?
Solar energy is cheaper than
other fossil fuels because we can get
an abundant source from the sun. in
sunny desert area, 50% of the sun’s
radiation that reach the ground
could be used to produce electricity
for businesses and industry and to
provide heat, light, and hot water for
homes. Experimental solar ponds can
also produce hot water to drive
generators.
Unfortunately, we can’t yet
power our homes entirely on
sunlight. Solar energy can only be
used effectively in bright light. Its
greatest potential therefore is in hot
countries that have clear skies for
most of the year. But, unfortunately
most houses are not in the sunniest
parts of the world. Moreover, in
order to harness solar power solar
cells are needed to convert sunlight
directly into electricity. Solar cells
are very cheap to run, but relatively
expensive to buy and many people
can’t afford them.
Needless to say, solar energy
is useful and non-pollution source of
energy. Unfortunately, solar cells,
the main to harness the sun’s energy
are still very expensive.
