Air conditioning makes pollution worse

A new study shows that the hottest days have the highest air pollution. Increasing air conditioning on hot days results in increased emissions from power plants of nitrogen oxides, sulfur dioxide and carbon dioxide. The study shows that increases in pollution of  3 to 4 percent per degree Celsius can occur. This may be due to partly to the increased use of out-dated and inefficient power stations which are brought online to address increased peak loads. Access more information here.
