节能利能与可再生能源

Energy Conservation and Energy Using and Recycling Energy

当今科技迅猛发展 ,能源在工业生产与民用生活中消耗量日益增大。我国的不尽合理的产业结构导致能源利用率很低 ,单位产值能耗是发达国家的 3～ 4倍 ,能源平均利用率只有 30 %左右 ,提高能源利用率和节能是当前的紧迫任务。我国常规能源资源相对不足 ,人均战胜量仅为世界平均水平的一半 ,能源供需矛盾十分突出。按目前开采能力和探明储量计算 ,我国煤炭可开采使用 15 0年 ,而石油仅 2 0～ 30年 ,所以当今必须重视研究能源发展的新思路和模式 ,开发可再生能源势在必行。未来的世纪 。

With science and technology developing, the need of energy increases in our lives and industries. Normal energy is lacking in our country, and the average is half of the average of the world. The conflicting between supplying and needing is apparent. So it seems that the energy may be gone. It is necessary that development of recycling energy is considered. The new energy and recycling energy will be the main energy in the future.
