I don't like how we talk about 100% renewables as if failing that means failure.

I'm happy with 90% renewables, a much easier goal, while we figure out the diminishing marginal returns later as technology breakthroughs and cost curves do the work for us.

Our objective is to minimize the area under the curve of future emissions. It's not "net-zero" in the abstract. Net-zero is just a proxy for the true objective. Getting to 90% renewables soon means less emissions (while being cheaper) than waiting an extra 10-15 years for 100% nuclear.
