Does running the AC use up gas?
Now you know the facts. Running the AC does use up a bit of extra gas in a traditional car. Doing so in an electric vehicle also requires extra energy, running down the battery a bit faster. So, you can become more efficient by limiting your use of the air conditioner in general, and only using it when you’re at a higher speed.
