Abstract: Due to the increasingly serious of energy crisis and environmental pollution problems，energy plants，for its characteristics of safety, environmental friendly，renewable and low cost，has become a hotspot of energy exploitation. With the continuous advancement of transgenic technology，the use of transgenic technology to cultivate high\|yield，high quality, efficient energy plant new varieties has made the corresponding results. This paper briefly introduced the concept of energy plants and classification，and outlined the application status of transgenic technology in increasing total biomass of plants, reducing plant lignin content，overexpressing cellulose degrading enzymes in plants，increasing oil content of oil plants and other aspects. The prospect of energy plant improvement using transgenic technology was also discussed，with the aim to provide references for future energy plant genetic engineering breeding research and its application.
