You may have known several kinds of police, traffic police, and street police. But have you ever heard of energy-saving (节能) policemen?

A group of 22 of these new policemen went to work last week in Beijing. They go around the city to see the use of energy in hotels, office buildings, shopping centers and other public places. One of their aims is to make sure that these places have set their air conditioning (空调) no cooler than 26 ℃.

"If everyone sets their air conditioning at 26 ℃, Beijing will save 400 million kilowatt-hours of electricity in one summer. That's one-third of all the usage of the city in the season," said a TV advertisement.

Other Chinese cities, like Wuhan in Hubei Province and Yangzhou in Jiangsu Province, are going to follow Beijing's steps in setting up a similar police team.

From 1986 to 2005, China met 20 warm winters. It means that Chinese cities have to spend billions of yuan solving the environmental problems every year.

To introduce a green life to the public, Beijing also held a show on energy-saving technology and productions last week. It attracted lots of attention.

"We want to tell people that there are certain ways to protect the environment. Each of us can find right ways to do it in our daily lives," said Liu Qianguang, an environmental engineer in Beijing.
