However, the chiller system of air-conditioner produces huge heating during the working and the heating will be released directly to the air so that it causes the city temperature to increase again, and then, accordingly, the city needs more power capacity again to feed the air-conditioner. It is a vicious spiral! Virtually other issues such as unemployment, hospital, sewage & rubbish, security and air quality, are also urgent. Even so, air quality among these issues must be the most critical one. Take Chile as an example. During the rapid development from 1970s to 1990s Chile experienced misery in air quality.
