問題詳情
Nuclear power stations are massive and complex structures. They are designed towithstand earthquakes and violent storms. They include many special safety devicesand systems that help to protect the plant, the people working in it and the public,even in the event of a serious accident. However, in spite of the preventive measures,accidents have occurred, for instance, at Three Mile Island in the USA and atChernobyl in the former USSR. These accidents have raised questions in the minds ofmany people about the use of nuclear energy to produce electricity.Therefore, some years ago scientists started to consider an alternative source ofelectrical energy----sunlight. Using sunlight as a source of energy offers considerableadvantages. Light from the sun is practically inexhaustible; in other words, sunlightcannot be used up. It is available everywhere. Besides, changing sunlight into electrical energy does not demand fuel such as coal or oil. The system of convertingsolar energy into electrical energy would do very little damage to the environment.
