The evaluation methods of low-carbon contribution based on the life cycle of low- carbon electricity technologies

In response to the global climate warming and achieving economic and society sustainable development, low-carbon economy is indispensable. Electric power industry is huge carbon dioxide emitter in China, so there is a difficult task in the energy conservation and emissions reduction. The development of low-carbon electricity technologies has important practical significance and strategic significance for the power industry to achieve energy conservation and emissions reduction. This paper studies low-carbon electricity technologies of electric power generation side and electricity using side in our country, analyzes low-carbon electricity technologies based on the life cycle theory, and then establishes low-carbon contribution to evaluate the contribution degree of low-carbon power technologies in power industry for energy conservation and emissions reduction, thus it provides a positive reference to low-carbon development in our country.
