序能源问题,是一个全世界普遍关心和重视的问题,随着经济建设的增长,人们越来越意识到了一种能源危机感。所以,节约能源,降低能耗越来越引起人们的关注。我国是发展中国家,尽管能源储量丰富,但单位国民经济产值的能耗高。能源有效利用率和发达国家相比还极低。因此,提高能源有效利用率,节约能源在我国尤其有着深远的意义,这也是我们现阶段的重要任务。电力所提供的能源属于二次能源。但生产电力的燃料乃是一次能源。一次能源不能 The issue of sequential energy is a problem that the world is concerned about and attaches importance to. With the growth of economic construction, people are increasingly aware of a sense of energy crisis. Therefore, saving energy and reducing energy consumption are attracting more and more attention. China is a developing country. Despite the abundant energy reserves, the energy consumption per unit of national economic output is high. The effective energy efficiency is still very low compared with developed countries. Therefore, improving the effective utilization of energy resources and saving energy resources are of far-reaching significance in our country. This is also an important task for us at this stage. The energy provided by electricity belongs to secondary energy. However, the fuel used to produce electricity is primary energy. Primary energy cannot
