Abstract

To promote the energy structure adjustment and clean energy development, this paper evaluates the global clean energy development level. Firstly, the global clean energy development level evaluation index system is established based on index system construction principles; secondly, the comprehensive weight is determined based on additive integration model, which is used to combine subjective and objective weights. Moreover, the variance minimal optimization method is used to select the combination scheme of dimensionless method and objective weight method, which could avoid the influence from subjective selection of method and enhance the stability of weighting. Thirdly, grey relational degree method and logarithmic range method are applied to evaluate the global clean energy development level. Then using the compatibility degree maximization and difference degree minimization model considers the compatibility and difference degree of the various comprehensive evaluation methods results and chooses the result with the maximization compatibility degree and minimization difference degree as the final evaluation scheme, which makes the evaluation result more scientific, robust, and reasonable. Finally, this paper empirically analyzes the 66 countries in the world to verify the effectiveness of the method and evaluates the development level of the region according to the spatial distribution map of the development level.

Highlights

With the development of global economy and the advancement of industrialization, the production and consumption of fossil energy continue to increase which leads to fossil fuel’s shortage
In the construction of the comprehensive evaluation model, considering the characteristics of the evaluation index system covering a wide range and the number of evaluation objects, this paper proposes the following principles for the comprehensive evaluation model of clean energy development level: (1) Applicability principle: the model should be applied to a large number of evaluation objects and evaluation indexes to meet the requirements of global evaluation
In terms of subjective weight, this paper is based on the weight model constructed in Section 3, aiming at selected index systems to establish questionnaire, calculating the scores of clean energy experts with G1-method to conduct index subjective weight amount

Summary

Introduction

With the development of global economy and the advancement of industrialization, the production and consumption of fossil energy continue to increase which leads to fossil fuel’s shortage. What is more, it comes a large amount of pollution in using fossil energy causing air pollution and prominent environmental deterioration [1]. It comes a large amount of pollution in using fossil energy causing air pollution and prominent environmental deterioration [1] These global problems are the severe challenges of sustainable development all over the world. It is of great significance to promote the construction of “The Silk Road Economic Belt and 21stCentury Maritime Silk Road” and the development of the global energy Internet [4]
