These things sound so obvious when you don't factor in the annoying little details like transmission of energy. System complexity also matters. There's this thing called "total cost of ownership" that paints a more honest picture regarding how these economics interact.

Using heat pumps to solve a problem looks fantastic in operational efficiency terms, but what happens if the control board breaks and the vendor decided to move on? Dumb, slightly less efficient appliances might actually be cheaper and better for the environment in total. If I have to create a pile of e-waste every 3 years just to save 10% on my energy bill for something that is already incredibly cheap in absolute terms, I think it could be argued I've made everything worse.
