    So AC is bad but heat pumps are better ? Can waste heat be used for something else ? Heating greenhouses ? Pumped into water to dissipate the excess heat or used to create steam for turbines ?

    Any other good use for excess heat ?

      Yes! There are plenty of uses for excess heat, especially if you like having hot water on tap, but it’s really difficult to capture or store waste heat, mostly because if the heat is available where it is needed, like the heater of a car in a cool day, it’s not waste heat at all. There is a point where the difference in temperature between the waste heat source and the environment is large enough that it could be used to create electricity, but usually it’s not worthwhile and the equipment needed would would be better used with a dedicated heat source or not at all. I dream of a day when we develop ways to harvest energy from heat more efficiently and can use waste heat for power.

        Well it sounds like it’s either we hear the environment or spend lots on capturing that waste heat

          Don’t get me wrong, there is no way to capture waste heat, it’s going out into the environment somehow
