Developing renewable energy is an important way to alleviate the energy crisis and the damage caused by climate change. However, the existing planning for renewable energy mostly focuses on a certain type of energy, without taking complementary advantages of multiple energy sources into consideration. The right thing to do is a coordinating and optimizing multiple energy planing. The Inner Mongolia Autonomous Region is rich in renewable energy and plays an important role in China's future renewable energy development map. This paper combines the spatial analysis technology and the multi-criteria analysis and evaluation methods to evaluate the potential resources of the bio-liquid fuel, the wind power and the solar power on the unused land of Inner Mongolia. And suggestions for the spatial layout of the coordinated development of three types of energies are made. It is shown that Alxa League has the potential for the development of three types resources at the same time due to its large area of unused land. For sweet sorghum fuel ethanol, in addition to Alxa League, Ordos also has a great development potential. For the wind power development, Bayannaoer and Wuhai cities can be given priority. For the development of the photovoltaic power generation, the focus should be put on Alxa League and Xilin Gol League.
