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.
What else can I help you with?

Does running the AC in a car affect the battery when not moving?
For most cars the air conditioning is powered by a belt from the engine and even if the car is only idling it will be running without any meaningful effect on the car's battery. For some hybrid drive cars the air conditioning is powered electrically, so that it can work even with the engine off. These will drain the car's battery some, but the air conditioning controller will automatically turn off the air conditioning before this becomes a problem then turn it back on as soon as the engine is automatically restarted when it is again needed to drive the car.
