The coming green power tide

Rising use of natural gas brings benefits to consumers, industry and economy

Millions of residents in northern Chinese cities will literally breathe easy this winter as the air will likely be a lot cleaner, and smog a lot thinner, given that natural gas will increasingly replace dirtier coal as power plant fuel in the region.

Natural gas sales are expected to rise more than 20 percent to 13.9 billion yuan ($2.1 billion) this year, according to China National Petroleum Corp or CNPC, the country's largest oil and gas supplier and producer.
