This report surveys China’s enormous energy transition to renewables. It begins by sketching the energy challenges China faces and its climate-change-related energy policies, in the context of the global geopolitics of the energy transformation. Next the report focuses on conventional energy sources (oil and natural gas), followed by electricity, and energy technologies. Although the report is intended primarily to survey developments to date, it concludes with some brief observations about the considerable energy challenges China faces in the years ahead.
