Residential and commercial energy efficiency opportunities : Taiyuan case study (Inglês)

The study explores the feasibility of substituting a variety of new technologies, or changes in the operation of energy consuming equipment, to determine how much potential exists in the residential, and commercial sectors of China. Taiyuan was chosen as a case study, because of its local pollution resulting from the extensive use of coal - local air, and water pollution are high, and harmful, thus a reduction in coal use would significantly improve pollution standards, in addition to lessening greenhouse gas emissions. However, because of the low price of coal in Taiyuan, and other non-economic barriers, energy efficient measures that could reduce household energy consumption, are not financially cost-effective (the exception being the energy-efficient stoves, from the household perspective), and in most cases, technologies are not fully developed into commercially available products. But, by and large, the development of those efficiency measures represent the least cost options available for reducing carbon dioxide emissions. And, while the trend in new construction is to move away from individual heating, and cooking stoves, to build instead centralized heating, and coal-gas distribution systems, neither of these options can be justified economically based on the cost of coal, given the current indoor temperatures. Looking at growth projections, China should focus attention on energy use in the sector, exploring other policy options for cost-effectiveness of energy efficiency measures, such as reforming pricing structures to soften demand.
