Abstract

Abstract:

China has achieved the first century goal to build a moderately prosperous society, but rural revitalization is one of the key issues to be faced and solved towards the second century goal of building a socialist modern country. At present, China’s rural areas are still facing multiple problems such as economic development, clean energy use, environmental protection and carbon emission reduction. Through rural energy transformation, a new rural energy system can be built. This could not only achieve the “dual carbon” goal of rural China, but also be the main solutions to promote the development of rural industries and rural ecological governance, and an important foundation to realize the rural revitalization strategy. In this paper, the potential, technical route, financing mode and significance of developing roof-top distributed photovoltaic system in rural China are thoroughly discussed and quantitatively analyzed. The results show that rural China are facing multiple problems including energy, environment and economic development. The development of new rural energy system based on distributed photovoltaic system on rural rooftops is one of the most effective pathways to solve issues of agriculture, rural areas, and rural people. This is also the breakthrough point for China to build a new power system and achieve low-carbon energy system.
