Energy technology revolution is the foundation for boosting energy consumption revolution, supply revolution, institutional revolution and strengthening international cooperation. The energy technology revolution is the support of a modern energy system that is clean, low-carbon, safe and efficient. It is an important part of building an innovation-oriented country. This paper states the energy situation and challenges in China, studies future energy structures in three time nodes including 2020, 2030 and 2050, and summarizes the common trend of the technology development to realize the collaboration of multi-field energy technologies. Also, the development direction of energy technology is proposed to realize the leapfrog development, and to build an energy technology innovation system with Chinese characteristics.
