Fig. 3.2 Energy intensity index of selected energy-intensive products (2005-2011). Note: The
energy intensity of selected industrial product in 2005 is 100. The energy intensity index of selected
industrial product from 2006 to 2011 is the energy intensity of that year divided by that of 2005
Source: the power supply efficiency data comes from China Energy Statistical Yearbook 2011 ;
data for other industrial products comes from industrial associations
crude oil processing industries dropped by 28 %, and the comprehensive energy
consumption of per unit production in coal-fired electricity generation, steel refining,
electrolytic aluminum and ethylene decreased by more than 10 %. Counted by the
decreasing energy consumption per unit product, the energy saving amount surpassed
0.3 billion tons of coal equivalent. The energy efficiency of high energy-consuming
products improved year-on-year and the gap between the energy consumption of
Chinese high energy-consuming products and the advanced level abroad shrank (See
Table 3.2 ). The energy saving and emissions reduction work of the industrial sector has
been strongly supported.
