Is air conditioning bad for the atmosphere?
Remember that air conditioning is powered by electricity. How that electricity is made will determine its affect on the atmosphere. If it comes from Solar or Wind power, there is no effect.

If the AC is in your car, then you will use more fuel, and emit more greenhouse gases as exhaust.
Use of exhaust gases for automobile air conditioning?

Why does running the air conditioning in a car use more gas?
Air Conditioning is a unit connected to the engine... when ac on, it connects to power from the engine to make it operate... it uses power making the engine work harder, consuming more gas. I've heard from research that driving less that 50mph(or 40 i think) with windows down is more fuel efficient.. while driving 40 or 50mph + and having the ac on is more fuel efficient.. because of drag from wind.
Do Australians use air conditioning?
