I agree with you that we should be exploring alternatives, but aircon is extremely energy efficient for how much thermal energy it moves (reaching 400% efficiency in some cases) . The problem isn’t aircon itself, but what is being used to power it (coal/natural gas power plants)
In fact the technology behind aircon can be expanded into a heat pump to both heat and cool, being more efficient than electro-resistive or gas heating. There’s even water heaters that will actually cool the area they’re in and use the heat they gather from the space to heat the water.
Technology Connections has a great series of videos that go in depth on both heat pumps and aircon.
Yeah, “air conditioning powered by solar/wind/hydro” can feel like it’s one big Rube Goldberg machine to make air cool, but the reality is that it comes together to make something that can scale really easily. I can’t imagine coming up with a design like what’s in OP for an apartment complex or condo building.
