Study On Evaluation Of Energy Saving Project Comprehensive Benefits

Today's society, the increasing shortage of resources, more and more serious environmental problems, while an increasingly competitive global economy, the environment to the traditional energy supply has brought new challenges, has restricted the social and economic development an important factor. In this case, as people increase awareness of energy conservation, increasing energy efficiency projects of social concern. In order to improve energy efficiency investment projects and policy-making level, we must attach importance to the evaluation of energy projects, energy projects continue to deepen the theory and methods of evaluation. But also to the development of ideas and energy of our consistent introduction of the concept of sustainable development into energy-saving project evaluation study. Need for a comprehensive energy efficiency project evaluation, but because of energy conservation projects with positive externalities, how to objectively evaluate the overall efficiency of energy saving projects, affect the feasibility and energy efficiency projects the enthusiasm of investors. Integrated energy-saving effectiveness of the project's scientific evaluation, is to promote the development of energy-saving projects, successful implementation and building a harmonious society.Firstly, energy efficiency projects in the construction of our brief discussion, based on the analysis of one of the main problems, and that caused our current energy-saving projects is an important cause of many problems in the project evaluation process is the lack of scientific evaluation means. In addition, this energy-saving projects for the economic analysis of external sexual characteristics. The nature of the various energy efficiency projects, attempts to study the theory of externalities the external benefits to energy efficiency projects clarity.Secondly, in order to fully reflect the overall efficiency of energy-saving projects, proposes to establish a comprehensive evaluation index system of comprehensive benefit point of view. Evaluation of domestic and international energy project by summarizing the main achievements and successful experience in the practical application, analysis of the significance of comprehensive benefit evaluation, the evaluation principles, contents and methods were discussed. Index system by establishing the basis of clear and basic principles, from the economic benefits, energy efficiency, social and environmental benefits are brought out 21 evaluation, constitute the overall efficiency of energy-saving project evaluation system using AHP to determine the index weight, and gives the overall efficiency evaluation value is calculated to determine the overall efficiency of energy-saving project evaluation model.Finally, a wind power project in Guangdong relevant data, the use of energy saving projects established Evaluation Index System of the overall efficiency of the project conducted case studies, designed to test the theories and methods of construction paper.
