consumption regions in 2010.
Based on the “proximity
principle” in energy usage, fossil fuels are usually consumed in cities near the source area,
rather than delivered to distant cities in order to reduce the overall transportation cost. For
example, raw
coal produced in Huainan
-
Huaibei coal base, which is located in Anhui, are
mostly used in Yangtze River Delta. Nearly all the coal used in Jing
-
Jin
-
Ji region and north
China are produced in the nearby Shanxi
-
Inner Mongolia coal base. Note that the Yangtze
river delta includes Anhui province and the Pearl river delta refers to Guangdong province
