Integrated Analysis of Carbon Dioxide Emissions Mitigation through Energy Efficiency for Coal-fired Power Industry in China

The coal-fired power industry contributes most CO₂ emissions among social sectors in China. This paper constructs a hybrid CGE model to simulate the effects of CO₂ emissions mitigation through energy efficiency for coal-fired power industry in China. Then the electricity generation, energy saving amounts, CO₂ emissions amount and CO₂ emissions intensity under strict energy efficiency policies from 2002 to 2020 are estimated for China´s coal-fired power industry. According to the calculation results, the performance factor of CO₂ emissions for coal-fired power industry cannot be effectively reduced to national target through energy efficiency in China by 2020, while CO₂ emissions amount will still show increasing trend. Renewable energy and other clean energy sorts should be substituted for coal in China´s electricity sector. The development of the coal-fired power technologies targeted at near-zero CO₂ emissions such as CCS technology also has become urgent in China.
