Solar energy is a long lasting source of energy which can be used almost anywhere. To generate solar energy, we only need solar cells and the sun. Solar cells can easily be installed on house roofs, so nonew space is needed and each user can quietly generate their own energy. Compared to other renewable sources, they also possess many advantages: wind and water power relies on turbines which are noisy, expensive and easy to break down. Solar cells are totally silent and non-polluting. As they have no moving parts, they require little maintenance and have a long lifetime.
However, solar energy also has some disadvantages. We can only generate solar energy during daytime because the system depends on sunlight. Besides, solar cellsrequire large area to work effectively. The main disadvantage of solar energy is that it costs about twice as much as traditional sources such as coal, oil and gas. This is because solar cells are expensive. Scientists are hoping that the costs of solar cells will reduce as more and more people see the advantages of this environmentally friendly source of energy.

about twenty percent of the world's present energy comes from the sun in one form or another. Special devices have already been made available to put on the roofs of houses and flats to catch the sun's rays and thus heat water. Thousands of these devices are now being used to provide energy in homes throughout the United States while more than a million solar water-heating units have already been built in homes in Japan. Other purposes for which solar energy is at present, being used include the separation of salt from seawater, irrigation and sewage disposal. For most people in developing countries, the need is not air-conditioners or central heating, but for cheap ways of cooking food, drying crops, and lighting house.
