China's total energy consumption in 2011 was 3.48 billion tons of standard coal, an increase of 7% over 2010. This means that the total energy consumption last year than last year, an increa

At the same time, automobile exhaust pollution is a difficult problem to solve, according to the State Environmental Protection Cent
