Fig. 1 also reveals that thermal power generation contributes around 80% of the total generation capacity in Zhejiang. Consequently, the power sector in the Zhejiang province is a major source of GHG. In 2007, it produced 314 MtCO2e, which accounts for 81.6% of Zhejiang's and 2.1% of the national GHG emissions (Zhejiang Provincial Government, 2010). The resource utilization efficiency in Zhejiang's power sector remains high due to a high proportion of larger-scale generating units. Table 1 lists the energy intensity of thermal power generation in China and Zhejiang province. Energy consumption in Zhejiang's thermal power enterprises to generate 1 kWh is noticeably less than the national average level. However, if we compare it to the international advanced level, the thermal power enterprises in Zhejiang province still have 6.7–11.5% improvement potential in energy efficiency.
