Another round of energy crisis is knocking at the door. In 2004, world oil consumption reached a new record, causing oil price in the international market to skyrocket amazingly. As for China, it was reported that many traditional mineral cities in northeastern China had run into predicament, with their economy collapsed and workers unemployed, only because coal had been mined out.

Fossil energy resources, including coal, oil and gas, are unlike sunlight, water power and wind power which are generated consistently. They're not practically reproductive during human history. Once consumed, they're gone forever. If they were to be exhausted before we could find sufficient reproductive resources to replace them with, we'd have to live in entire blackout again like our ancestors have done thousands of years ago. That's of course not what anyone would want to see.

Due to technical limitations, people still have to utilize these resources now.

As a result, we must economize them most cleverly. New techniques should be developed and applied to reduce energy cost in industry and daily life. Alternative energy should be employed wherever possible. Eradicate any practice that wastes energy. Humans have overcome so many crises in history, and we're sure to win this time also.

新一轮的能源危机在敲响警钟。 2004年，世界石油消费量达到了一个新的纪录，能源危机导致国际市场上的石油价格扶摇直上，令人惊讶。至于中国，据报道，在中国东北的许多传统矿业城市运行陷入困境，他们经济崩溃并且工人失业，不仅是因为煤炭已经被开采完了。

化石能源资源，包括煤，石油和天然气，不像阳光，水，风电不断的产生。他们在人类的历史上几乎不会再产生了。一旦消耗殆尽，这些能源将永远不会再生。如果在他们被耗尽之前，我们还没有找到能够取代它们的资源，我们将不得不生活在一片黑暗之中，就像几千年前我们的祖先。这当然是任何人都不愿意看到的。

由于技术的限制，人们仍然必须利用这些资源。

因此，我们必须很巧妙的去节约资源。应该尽力开发和应用新技术，在工业和日常生活中降低能源成本。要尽可能的采用替代能源。消除任何浪费资源的行为。人类已经克服了这么多历史上的危机，这个时候我们也一定会取得成功。
