In order to analyze the causes of high abandoned new energy rate in China, and using data presented by National Energy Administration from 2004 to 2015, this paper comprehensively summarizes the process of China's new energy development in the past twelve years. By calculating new energy power connected to grid and abandoned new energy rate in regions and provinces of China, it sums up six characteristics of China's new energy development and presents five causes which make high abandoned new energy rate in China. From the realization of the sustainable development of new energy, it puts forward six solutions, which need to strengthen the unified power system plan at the national top-level and enhance power energy allocation ability. Finally, it predicts the development prospects of China's new energy.
