『Abstract
China is the world's second-largest energy producer and consumer,
so that it is very necessary to analyze China's energy situation
for saving energy consumption and reducing GHG emission. Energy
flow chart is taken as a useful tool for sorting out and displaying
energy statistics data. Energy statistics data is the premise
and foundation for analyzing energy situation. However, there
exit many differences between China and foreign energy balance.
Based on the international criterion of energy balance and some
advices by related experts, the author properly adjusts China's
energy balance. And the purpose of this paper is to draft China's
energy flow chart for 2007, which is used to study the characteristics
of energy production and consumption in China. We find that: (1)
coal is the main energy in China, which accounted for 73.2% of
total energy supply in 2007; (2) thermal power accounted for 83.2%of
the total electricity supply, and 78.43% thermal power was based
on coal; (39 in 2007, the secondary industrial sector consumed
about 69.93% of energy; (4) China's energy utilization efficiency
was about 33.23% in 2007.
