In order to build an environment-friendly society and realize the coordinated allocationand effective utilization of resources and finally achieve China’s energy supply security, it isimperative to vigorously develop new energy sources. This study establishes a four-level newenergy power generation (NEPG) development index system from multiple dimensions. Takingthe installed capacity and generating capacity of China’s NEPG in 2016 and 2017 as samples, weused the improved entropy method, to analyze the development of different types of NEPG among31 provinces from three aspects: absolute value, relative value, and incremental value. Finally, wecomprehensively evaluated the NEPG development in each province. The empirical analysisshows that the spatial distribution of NEPG development in China is uneven, the growth rate isdifferent, the development gap is obvious, and the development efficiency is quite different.
