One way is to say "well I don't care, I won't do anything until I don't get a choice, and probably at that point it will hurt a lot".
Another is to face it, start doing things, and pushing your politicians to enforce very big plans. One problem I see is that everyone says "I would be ready to do a lot more if I knew everyone else did", but when it's time to vote, they don't.
Not being ready to go lower than 24.5 degrees (doesn't have to be 19 if that's not bearable for you) in winter does not sound like you are ready to do much, though.
As I said before, I'm living in a house insulated up to the highest standard, I have a heat pump and a solar PV, the largest PV array in the estate. I think this is something reasonable. I work remotely, I don't drive much and I drive with very good MPG, I've figured out that my car has the best MPG at 90 kmph so I drive about 90 kmph, I don't travel often, I'm carefully sorting my waste (most people throw everything into the black bin), I'm trying to buy things which last and I'm trying to repair and sell, I think if everyone does that it would make some reasonable impact.
Though I don't think that 19 or whatever degrees is something of your business.
> you are ready to do much
I'm not ready to do unreasonable (or idiotic) things. Why 24.5? Because I've figured out that it's the most optimal temperature for me.

Let's say that your case is extremely special and for you it does not make sense to not overheat, it does not make it unreasonable (or idiotic) to say that the vast majority of people should not overheat, does it?
At this point I see zero reasons to conserve damn solar energy while half of the country still uses OFCH.
