Will solar energy ever be a main
source of energy for industrial societies? Solar energy is cheaper than any
fossil fuel because we can get an abundant source of energy from the sun.
source of energy for industrial societies? Solar energy is cheaper than any
fossil fuel because we can get an abundant source of energy from the sun.
In sunny deserts,
the sun’s radiation that reaches the ground can be used to produce electricity
for industries and homes. In one experiment, solar ponds can produce hot
water to drive generators.
Unfortunately, we
can’t power our homes entirely on sunlight. Solar energy can only be exploited
in bright light. Its great potential, therefore, is in countries that have
clear skies for most of the year. Most houses, however, are not in the sunniest
part of the world. In addition, to convert sunlight directly into electricity,
solar cells are needed. Although they are very cheap to run, relatively they
are expensive to buy and many people can’t afford them.
