Save the Energy Resources 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.
