I believe this is mainly due to China's strong sense of crisis regarding energy supply. If it had as abundant fossil fuel resources as the United States and Russia, it likely wouldn't have invested so heavily in diversifying its energy sources. The development and support of new energy vehicles can also be largely attributed to this.
Heavy dependence on coal has led to severe environmental pollution. As winter approaches and cold fronts sweep down from the north, increased heating needs drive up thermal power generation, releasing more pollutants into the air. During periods of stagnant weather with no wind or rain, smog settles over the sprawling plains, triggering both public health concerns and mounting pressure on the government to address the issue and explore alternative energy sources.
