Abstract

A scientific, comprehensive and integrated assessment of urban energy development is of great significance for the establishment of a clean, low-carbon and efficient urban modern energy system. From the perspective of carbon neutrality, this paper sets 25 evaluation indicators in seven dimensions: energy supply, energy consumption, energy efficiency improvement, clean and low-carbon, safety and reliability, low-carbon transport, and scientific and technological innovation, and constructs a secondary indicator system for evaluating the strategic development of urban energy. The system adopts the hierarchical analysis method to determine the weights of the indicators, the double-baseline progression method to standardize the indicator scores, and finally the weighted composite index method to calculate the level of urban energy strategy development. This paper applies the index system to evaluate the current energy development status of Wenzhou city in 2020 and 2022, and to predict the energy strategy development in 2025 and 2030. The scores of Wenzhou city's urban energy strategy development level in the corresponding four periods are 63.56, 70.59, 77.87 and 85.06, indicating that by 2023, Wenzhou city's urban energy development level will go from medium development to high development. Wenzhou City should accelerate the proportion of renewable energy in the future. It is necessary to complement multiple energy sources and improve the integration of heat, electricity, gas and cold. In terms of end consumption, it is necessary to improve the efficiency of energy use, reduce energy intensity, implement electric energy substitution and form an energy consumption pattern centered on electricity.

碳中和视角下城市能源战略发展指标评价体系的建立与应用研究

科学、全面、综合地评价城市能源发展状况，对于建立清洁、低碳、高效的城市现代能源体系具有重要意义。本文从碳中和的角度出发，从能源供应、能源消费、能效提升、清洁低碳、安全可靠、低碳交通、科技创新七个维度设置了 25 个评价指标，构建了城市能源战略发展评价二级指标体系。该体系采用层次分析法确定指标权重，采用双基线递进法对指标分值进行标准化处理，最后采用加权综合指数法计算城市能源战略发展水平。本文应用该指标体系对温州市 2020 年和 2022 年的能源发展现状进行评价，并对 2025 年和 2030 年的能源战略发展进行预测。温州市城市能源战略发展水平在相应四个时期的得分分别为 63.56、70.59、77.87 和 85.06，表明到 2023 年，温州市城市能源发展水平将从中度发展走向高度发展。温州市未来应加快可再生能源比重。要多能互补，提高热、电、气、冷一体化水平。在终端消费方面，要提高能源利用效率，降低能源强度，实施电能替代，形成以电力为中心的能源消费格局。

期刊介绍： With ICT pervading everyday objects and infrastructures, the ‘Future Internet’ is envisioned to undergo a radical transformation from how we know it today (a mere communication highway) into a vast hybrid network seamlessly integrating knowledge, people and machines into techno-social ecosystems whose behaviour transcends the boundaries of today’s engineering science. As the internet of things continues to grow, billions and trillions of data bytes need to be moved, stored and shared. The energy thus consumed and the climate impact of data centers are increasing dramatically, thereby becoming significant contributors to global warming and climate change. As reported recently, the combined electricity consumption of the world’s data centers has already exceeded that of some of the world''s top ten economies. In the ensuing process of integrating traditional and renewable energy, monitoring and managing various energy sources, and processing and transferring technological information through various channels, IT will undoubtedly play an ever-increasing and central role. Several technologies are currently racing to production to meet this challenge, from ‘smart dust’ to hybrid networks capable of controlling the emergence of dependable and reliable green and energy-efficient ecosystems – which we generically term the ‘energy web’ – calling for major paradigm shifts highly disruptive of the ways the energy sector functions today. The EAI Transactions on Energy Web are positioned at the forefront of these efforts and provide a forum for the most forward-looking, state-of-the-art research bringing together the cross section of IT and Energy communities. The journal will publish original works reporting on prominent advances that challenge traditional thinking.
