Sustainable Development of Green Energy Efficiency of Enterprises Based on Circular Economy

With the development of social economy, energy and environmental problems are increasingly prominent.In this situation, green energy efficiency management of enterprises has gradually become a solution to energy and environmental problems.This paper aimed to study how to analyze and study the sustainable development (SD) of green energy efficiency of enterprises based on circular economy, and described the data envelopment analysis (DEA) method.The experiment in this paper analyzed the present situation of green energy efficiency in enterprises by conducting a survey of 200 enterprises with questionnaires.The traditional green energy efficiency evaluation model and the green energy efficiency evaluation model in this paper were used to evaluate and analyze enterprises X and Y.It can be seen from the data that the green energy efficiency evaluation of the traditional model and the model in this paper for Enterprise X in 2022 was 0.79 and 0.87 respectively, while the actual green energy efficiency was 0.88.The green energy efficiency evaluation of the two models for Enterprise Y in 2022 was 0.36 and 0.52 respectively, while the actual green energy efficiency was 0.51.To sum up, the enterprise green energy efficiency evaluation model proposed in this paper is feasible.
