I didn't miss that at all! I think we should definitely build more solar and wind.
I also think we should build more nuclear. I've seen estimations saying we could supply the current grid demands with renewables in about 10 years time if we start building now. Thing is, in ten years, power demand will have doubled. So we should build renewables and nuclear. Any other plan will end up using coal oil and gas.
I think you missed my point, which is that if we had invested early on (think 1970s) in wind and solar, by today they would be at a capacity such that we would need far less nuclear, coal, oil, and gas than we do currently.
