日本电力企业的循环经济模式——以中部电力公司碧南火力发电厂为例

The Circular Economy Pattern of Japanese Electricity Industry——A Case Study of CHUBU Hekinan Thermal Power Station

近年来,出于对能源价格和能源安全的考虑,日本不断提高煤电在电力工业中的比重,但环境污染却没有因此而加重,原因主要在于日本的煤电生产企业将循环经济的理念贯穿于生产的全过程,从煤的储存、传送(全封闭进行)、燃烧,到副产物的循环、加工、再利用都尽可能节约、清洁,严格执行减量化、再利用、再循环的循环经济模式,以促使其企业生产的负外部性降到最低,并努力提高其正外部性。这种理念为中国电力企业的发展提供了很好的学习范例,对处于资源储量严重不足的日本的经济发展模式进行研究,对于中国协调经济发展与能源供给和环保之间的关系具有非常重要的意义。

The consideration of energy prices and energy security has driven Japan to raise the proportion of coal fired power in electricity industry. However, air pollution has not aggravated, mainly because the Japanese coal fired power plants adopt the idea of circular economy through out the processes of production. A circular pattern of saving, cleaning, reducing, reusing, and recycling has been carried out from storage, transmission and burn- ing, to the recycling, processing and reusing of the outgrowths. Negative externalities are minimized while posi- tive externalities are improved. This pattern can be taken as a good lesson for chinese electricity industry. The developing pattern of energy scareed Japan may provide important implications for China to balance the relation of economic development, energy supply and environment protection.
