Its not free the alternator puts an additional load on the engine. The best defense against decreasing fuel economy is actually pretty simple use your windows at lower speeds and turn on the air when you hit the highway. In other words there arent many.
AC does cut gas mileage significantly 10 is a common figure. According to the test driving at 50 or 55mph with windows open was worse for the mileage. How much gas does AC use.

Of course open windows increase drag which also reduces fuel economy but the impact isnt as great as running the AC at lower speeds.
AC works by transferring heat. However gas is used to operate the heat. However in some situations using the AC can be more efficient than not using it.
Driving with the air conditioner is more fuel efficient than driving with the windows down. In a similar test performed by Edmunds using a Toyota Tundra they saw a decrease in fuel mileage of almost 10 when using the air conditioner as opposed to driving with the windows down and the air conditioner off. This method of air conditioning is perfect for homes with baseboard heating and does not require duct work to operate.
For a car that gets about 30 MPG thats equal to a loss of 75 MPG. There are a few other ways of transferring heat peltier effect for one but gas or freon are by far the most pervasive. It could increase your fuel usage by as much as 10 per cent and the effects are.

The running of AC does burn gas but the open windows enhance the vehicles aerodynamic drag making the engine to work harder and burn more fuel. Opening your windows also cuts gas mileage by about the same amount because of increased drag the comparison is against closed windows AC off. Yes like many of your cars features the air conditioning system uses gas.
Your cars fuel efficiency is affected by multiple factors. Two vehicles were used in the test one was a full size SUV with an 81-liter V-8 engine and the other was a full-size sedan equipped with a 46-liter V-8 engine. The air conditioner draws its power from the engine which uses some gas but with todays cars this use of gas is minute.
The SAE found that running an air conditioner in an automobile decreased gas mileage by 5 to 10. Having windows open can cost you fuel which pretty much everyone knows by now but so can air conditioning which can increase fuel consumption by 8-10. Heat use does not affect gas mileage by any significant amount its just letting hot coolant flow through a little radiator heater core to heat up air.
Initially the mixture is heated by natural gas and ammonia condenses outside the home in a coil. If you didnt want to use gas or did not have your gas line on you would only be able to use half of your HVAC system. When you compress a gas the molecules bunch together and this generates heat.
An obvious solution may be to buy an EV. Mar 18 2008 Maybe as much as a dropgallon. The air conditioner draws energy from the alternator which is powered by the engine.

If you are not considering an HVAC system for your home there are other AC units that are smaller and sometimes portable. The short answer is yes with the air conditioning running the car burns more gas than without it.

The AC in your car can decrease the fuel economy of your car up to 20 in some vehicles but it depends on the type. It depends on your car but in most cases the air conditioner will use less gas if the speed of the car is above 45 miles per hour. The primary choices to consider are running the air conditioner with the windows up or turning off the air conditioner and either using the fan-only setting or no setting.
The whole unit works in a cycle with the beginning and end products of the reaction both being a mixture of ammonia and water. Releases fewer greenhouse gases than burning oil or coal does to produce the same amount of.
