Improvement of energy intensity of GDP during the 11th FYP (Source: National Bureau
of Statistics of China [

])
the energy-intensity improvement rate advanced to 5.02 % and 5.23 % decline rates
in 2007 and 2008, respectively.
Affected by the global financial crisis, Beijing implemented a stimulus spending
package worth 4 trillion RMB, mainly flowing to infrastructure and manufacturing
projects.
This contributed to a slowdown in the rate of decline in energy intensity to only
3.66 % in 2009 and 4.05 % in 2010 (see Fig.
2.10
).
Nevertheless, the energy-intensity improvement target has been achieved. No
matter whether it is 19.06 % or even lower, it is still in the 20 % range.
Moreover, the 20 % energy-intensity reduction target was in the context of an
expected annual GDP growth rate of 7.5 % for the 11th FYP. Accomplishing a 19 %
decline in energy intensity appears more remarkable since the actual GDP growth
rate stood at 11.2 %.
It is shown in Table
2.4
that fixed energy-savings under 7.5 % GDP and 20 %
energy-savings were about 678 Mtce while fixed energy-savings were 760 Mtce
under the real case, i.e., with average annual GDP growth of 11.2 %.
Compared to estimates in the 11th FYP, an additional 87 Mtce must be saved to
achieve a 19.1 % reduction that was achieved in reality.
Energy consumption per unit produced was decreased, along with unprece-
dented reductions in energy consumption per unit production for copper smelting
and caustic soda (both reduced by 35 %), cement and crude oil (both reduced by
28 %), standard coal consumption for power plants, steel, electrolytic aluminum,
and ethylene (all dropped by more than 10 %).
Calculating by unit product energy consumption reductions, energy savings
exceeded 0.3 billion tce. Making technical improvements in energy intensive
industries has contributed much to the realization of meeting energy-savings and
emissions reductions targets.
