Cars are not the only drain on energy resources. The generation of electricity also causes problems. Although it has to be conceded that everybody needs electricity, there is no getting around the fact that electricity is often used wastefully. For example, are all large neon lights in cities really necessary? These lights could be turned off when not in use. Energy saving is not enough on its own, though. In the longer term, we must find alternative sources of power. The most commonly-made suggestion is to expand nuclear power, which does not cause pollution. However, the possibility of nuclear accidents may mean it is not worth the risk. On the other hand, clean sources of energy do exist, including solar, wind and hydro-electric power. It is important that energy be conserved whenever possible and that research into alternative energy sources be continued.
汽車不是唯一消耗能源的方式。發(fā)電同樣會引發(fā)這類問題。雖然我們必須承認,每個人都需要電,但是電時常被浪費,這是一個不爭的事實。譬如,是否真的有必要打開城市里的所有大型霓虹燈?是否可以在不需要的時候就關掉這些燈? 不過,光靠節(jié)能本身是不夠的。從長遠的角度來看,我們務必要找到替代性能源。最通常的建議就是擴大核能的使用,它不會造成污染。然而核事故存在的可能性,可能意味著我們實在不值得冒這個險。另一方面,確實還存在著諸多清潔能源,包括太陽能、風能和水力發(fā)電。 重要的是,應盡可能保護現有資源,并繼續(xù)研究替代性能源。
