Technology options for reducing CO2 in China's electricity sector in 2010–2030: From the perspective of internal and social costs

摘要: : This paper creates a technology roadmap for China's electricity sector on CO2 mitigation based cost-effective analysis (CEA) and cost-benefit (CBA). We use targets 2020 2030 to determine the required implementation degrees of 13 selected power-generating technologies. According initial investment, operational costs, external costs major pollutants, we assigned priority rank each technology, which is derived basis internal social costs. A comparison present value generating technologies shows that hydroelectricity bears highest total cost, while cogeneration heat power lowest cost. The with benefit also hydroelectricity, carbon capture sequestration (CCS) yields benefit. By 2030, 6 can realize net benefits all except CCS benefits. top three levelized cost are: power, biomass generation, wind generation. Based integrated gasification combined cycle,
