A study found that waste heat generated by a city’s worth of air conditioners during a heatwave can raise the outside temperature by more than 2 degrees Celsius.

      Even without AC running, your house is still consuming electricity that eventually radiates to the outside.

        There are orders of magnitude difference between what the air conditioning does, and what you’re referring to.

          Did I accidentally post metrics that are incorrect? I certainly don’t remember that. Tens of watts times hundreds or millions of homes will still have a measurable effect even without AC. It’ll just be smaller and I don’t think anyone is going to argue that.

            How dense do you think these homes are?

            Just read the article

            The measurable effect is from the heat pumps.

            Heat pumps are exceptionally efficient

      Right, but the area the heat was removed from gets colder. When looking at the city as a whole, the transferred heat cancels out. The only heat added to the system is the additional energy used to transfer the heat.
