Will solar energy ever be a main source of energy for industrial societies? The solar energy is cheaper than any fossil fuel because we can get the 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 of 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.

From the text, we know that …

a. converting solar energy into electricity is expensive

b. it is easy to convert solar energy into electricity

c. most of people in bright sunny areas are use solar energy

d. solar energy generators can be found in most houses

e. the potential source of solar energy can be only be found in desert areas
