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.汽车不是唯一消耗能源的方式。发电同样会引发这类问题。虽然我们必须承认，每个人都需要电，但是电时常被浪费，这是一个不争的事实。譬如，是否真的有必要打开城市里的所有大型霓虹灯？是否可以在不需要的时候就关掉这些灯？
不过，光靠节能本身是不够的。从长远的角度来看，我们务必要找到替代性能源。最通常的建议就是扩大核能的使用，它不会造成污染。然而核事故存在的可能性，可能意味着我们实在不值得冒这个险。另一方面，确实还存在着诸多清洁能源，包括太阳能、风能和水力发电。
重要的是，应尽可能保护现有资源，并继续研究替代性能源。
