In order to satisfy the energy demand in the 21st century with reducing CO_2 intensity, the following three technology groups have to be prepared. (1) Efficient use of fossil resources: In preparation for the oil production peak, we will switch to natural gas, and then to coal, which has a comparably rich volume of resources. However, it is important to improve effectiveness of use of fossil resources such as power generation (conversion) efficiency. Therefore, gasification power generation (fuel production) technologies and highly effective power generation technologies combined with fuel cell are required. Also, CO_2 capture and sequestration (CCS) technologies are essential, since fossil fuel emits CO_2. (2) Nuclear power utilization technologies: Effective use of nuclear fuel resources is prospective. Therefore, it is fundamental to improve the efficiency of the current light-water reactor, and in the meantime to establish nuclear fuel cycle for better resource utilization and recycling. (3) Renewable energy utilization technologies: It is important to improve effectiveness of power generation (conversion) by renewable energy such as solar power, geothermal, wind power and biomass, at the same time, energy saving and energy creation have to be progressed on the demand side.
