In the process of adjusting primary energy supply structure, the electric power
sector, as the energy conversion department, is supposed to play a leading role.
Since coal power dominates China's electric power structure and thermal power
units account for 73 % (among which above 99 % are coal-fired power units), the
electricity generated from coal took up nearly 80 % of the total. Therefore, to
promote low-carbon green development of the industrial sector, the adjustment of
the electric power supply structure and low-carbon transformation should be
enabled. During the 11th Five-Year Plan period, a series of major actions was
taken by the electric power sector to adjust the electric power supply structure and
speed up low-carbon transformation. The ratio of non-fossil energy power units
such as hydropower, nuclear power and wind power increased from 24.4 % in 2005
to 26.5 % in 2010.
In the next decade (to realize the national goal of reducing carbon dioxide
emissions intensity and other binding energy saving and emission reduction indexes)
optimization of the electric power supply structure is a priority. Hence, China's top
five power generation enterprises have made their strategic development plans, in
which the adjustment of the electric power supply structure and the enabling of low-
carbon transformation are key elements. According to the electric power development
planmade by the Chinese electric power sectors, the basic idea of future electric power
development is: Develop hydropower generation as a top priority; optimize the
development of coal-fired power generation; vigorously develop nuclear power;
actively promote new energy power generation; appropriately develop natural gas
power generation and develop distributed power generation, all according to the local
situation. Based on this development concept, the two basic trends of low-carbon
evolution for the future electric power supply structure should be: hydropower grows
while coal-fired power decreases and non-hydropower construction moves forward.
3.1.2.4 Development and Popularization of Energy Saving and
Low-Carbon Technology
The low-carbon development of China's industrial sector is fundamentally dependent
on advanced technology. To explore the potential of energy saving and emissions
reduction requires corresponding support and basic back-up. During the period of the
11th Five-Year Plan, China's industrial sector has made great endeavors to research and
popularize low-carbon technology, particularly in terms of industrial energy efficiency
techniques. A large number of major industrial energy efficiency improving techniques
have been rapidly disseminated, including USC thermal power generation technology,
dry quenching technology, furnace top pressure power generation technology, cement
kiln pure low temperature waste heat power generation technology, synthetic ammonia
comprehensive energy saving technology and regenerative combustion technology
In terms of the high energy-consuming industrial sector, there are currently
hundreds of available mature energy-efficiency improving technologies. However,
due to technical and financial risks, a lack of investment and reduced information
flows, the adoption ratio of these energy efficiency-improving technologies still
remains low. On the other hand, as the technologies improve and develop they will
continue to mushroom, suggesting the energy saving and emissions reduction
