Research on the low carbonization of clean energy use in rural residential buildings in China under the background of “carbon peaking and carbon neutrality”

Abstract

As an important part of the construction industry, rural residential buildings are characterized by low energy utilization, unreasonable structures and low consumption levels, and it is particularly important to study their low-carbon transformation and evaluation system. In view of the many low-carbon transformation needs of rural residential buildings, the existing research results were analyzed in depth, and the coefficient of variation method was used to identify the important factors affecting the low-carbon transformation of rural residential buildings, and the evaluation system of rural residential buildings’ low-carbon transformation was determined by Analytic Hierarchy Process (APH), and the system was used in a rural residential building low-carbon evaluation study. The results show that the influence of “energy use”, “envelope structure” and “economic factors” on the decarbonization of buildings is obvious, with the weights of 36.4%, 24.5% and 19.5% respectively. Among the secondary indicators, “clean energy utilization”, “electricity consumption”, “external wall insulation system” and “window performance” are the most important factors in reducing carbon emissions in rural areas. The most critical influencing factors for the low carbonization level of clean energy in rural residential buildings are “window performance”. Finally, based on the constructed low carbonization evaluation system, we propose a targeted solution strategy to provide a theoretical basis for the establishment of an effective low carbonization evaluation system for clean energy in rural residential buildings.

Analysis of China's offshore wind power development trend based on bibliometrics

“…Although China's offshore wind power started relatively late, with the support of national financial subsidies, incentive electricity prices, and other policies, its development has been unstoppable in the past decade, and it is also in a leading position in the international offshore wind power field. As of 2022, the cumulative grid connected installed capacity of offshore wind power in China has exceeded 30 million kilowatts, continuously maintaining the world's largest offshore wind power installed capacity [15] , and is expected to become the world's largest offshore wind power market in the future [1] . Based on current data, it is expected that the future development prospects of offshore wind power in China are still broad [16], [17] .…”

“…China has more than 3 million square kilometers of sea area, rich offshore wind power resources can be developed, according to relevant data statistical analysis, within 200 kilometers offshore, China's offshore and far-reaching sea wind energy resources technology development potential of about 2.25 billion kilowatts [13] , has an inherent advantage in the field of offshore wind power development [14] . Since the two-carbon goal was proposed, China has accelerated the energy revolution, accelerated the planning and construction of new energy development and utilization [15] . Due to the development advantages of offshore wind power itself, as well as China's objective environmental conditions and energy needs, the development of offshore wind power will become an inevitable choice for China to vigorously develop new energy.…”

Research on Path Optimization of Industrial Energy Technology Innovation under the Constraint of "Dual Control" Goals: A Case Study of Bengbu City, Anhui Province

“…According to IOS standards, processes with unclear process level, inability to obtain data lists, and a contribution of less than 1% to carbon emissions results are not considered. Due to the fact that the production stage of the solar photovoltaic power generation life cycle is the main stage of energy consumption and material consumption, we will focus on introducing the energy consumption, material usage process, and environmental impact of the production stage [5]. Taking the CIGS thin-film solar cell modules produced by Kaisheng Photovoltaic Materials Co., Ltd. as an example, the details are as follow, The production process of copper indium gallium selenium thin film solar cell modules can be divided into two stages: battery manufacturing and module packaging.…”

Research on a Resource Modeling and Power Prediction Method Based on Virtual Aggregation

“…Within the aim of carbon neutrality, there are three major trends in China's energy system: firstly, there is the electrification of the energy system [1], which means that, by 2050, the proportion of primary energy to electricity conversion and the proportion of electricity to terminal energy consumption are expected to increase to 80% and 60%, respectively; secondly, the low-carbon power system is expected to increase the proportion of nonfossil energy generation from the current 33% to 84-90% by 2050 [2]; and thirdly, the decentralization of energy and power systems is being sought. The mode of energy development and utilization will shift from centralized to distributed, and the form of energy systems will undergo profound changes [3].…”
