In view of the inevitable shortage of oil resources,or a so-called post-oil era,this article analyses the current utilization of carbon-containing energy, calls for a down-to-earth reserch of find the best utilization of carbon-containing energy so as to readiust the current energy consumption pattern and ease the over dependence upon oil resources. The author starts his analysis from the element structure of carbon-containing energy, proposes some suggestions including the full utilization of oil resources to produce transportation furels and petrochemical feedstock, the rational utilization of coal to curb the industrial and civil consumption of fuels, the reasonable utilization of natural gas resources to develop natural-gas-fueled vehicles and GTL,the full utilization of biomass to produce motor fuels, biomaterials and organic chemicals.
