Abstract: Energy is the power of economic growth and development. Energy security is highly significant for political stability, social development and national security. At present, many countries are making great efforts on developing renewable energy including biomass energy so as to ensure energy security and decrease import and dependence on external energy. In this paper, it is proposed that utilizing biomass energy scientifically is one of the approaches solving the problem of Chinese energy on the basis of analyzing the characteristics, status quo and problems on energy utilization in China according to abundant data. Moreover, sustainable development system of biomass energy is designed in order to provide some references for promoting the development of biomass energy in China.
