is the biggest contributor to the growth in energy use, followed by population
and end-use energy mix. The main inhibitors of energy consumption increase are
economic structure, end-use energy intensity and energy supply efficiency. The
adjustment of end-use energy mix is mainly manifested in the switch from coal
to electricity. Energy consumption has grown as electricity is more responsible
for primary energy consumption than coal. However, exceptions exist in a few
regions. For example, the end-use energy intensity in Xinjiang and Shanxi and
the energy supply efficiency in Shanghai have not been improved, which may
have to do with the transfer of energy-intensive industries and underutilization
of production capacity, etc.
3. Per capita energy consumption is the most important driver for the growth of
residential energy consumption in all regions. From 2011 to 2016, 26 provinces
and municipalities reported increase in residential energy use, as shown in
Fig. 1.14. The red dots represent the total change in residential energy consumption in each region over the five years, ranked from the highest to the lowest.
The bar chart shows the changes in energy consumption caused by different
drivers. The most important driver is per capita energy consumption. Of all the
drivers, only improvements in the efficiency of energy supplies have had a positive impact on curbing growth in energy use. It should be noted that although
residential energy consumption only represents 1/7 of that in the overall economy,
its growth is 3.5 times that of the economy (the national average). Therefore, the
increase in residential energy consumption also warrants more attention.
The above research points to great disparities among various regions in China
in terms of the status and trend of their energy systems, which calls for specific
targets and paths of regional energy transition. In addition, the state should explore
