Policy effectiveness and environmental policy Assessment: A model of the environmental benefits of renewable energy for sustainable development

Abstract

The further development of integrated energy systems at the city-region level is an important way to improve the efficiency of integrated energy use, enhance the use of renewable energy and improve the economy and safety of energy operations. The development of integrated energy systems in urban areas is still in its infancy, and there is a lack of professional energy indicators in terms of comprehensive evaluation, as well as a lack of linkages with engineering practice. The development of operational and adaptable evaluation indicators and methods aids in assessing the impact of integrated energy systems on the environment, economy, and society. The quantitative processing results of indicator weights and indicator values are given, supported by historical operational data of the energy system, calculated data, and evaluation survey data. First, the fundamental model of comprehensive evaluation is built. The initial weights of indicators are then determined using the hierarchical analysis approach, and the entropy weight method is utilized to make changes to generate the target system’s combination weights. Finally, the fuzzy evaluation approach does the entire assessment computation to focus on and improve the important indicators and provide recommendations for optimizing the system’s overall advantages. Finally, we demonstrate the effectiveness of the proposed method through comparative experiments.
