We need to go to zero and gas furnaces cannot. (Horribly inefficient synthetic fuels excluded.)
In that context current electricity generation does not matter. It‘s an infrastructure change that allows for future zero emissions. Just like EVs.

The tools in our disposal to reach 20% or 30% are available today, if we can understand them. And also, as long as we don't let perfection be the enemy of good.
We will probably never tackle the 90% to 100% problem in our lifetime. It is best to focus upon the problems that are in front of us, and that we can in fact solve or fix within our lives.
Given the lifetime of gas furnaces and what we know about climate change it is madness to even consider using them in brand new construction now.
Gas was and is the right tech for transitioning. But you seem to be stuck in the 90s or early 2000s when that kind of policy would have made sense. It’s too late and getting later.
