It's probably better, but don't forget that this is inherently a global problem. Scotland is running 100% renewable - so what, who cares? Not only it's not enough (the country is small), they also import a lot of goods with manufacturing energy footprints that released co2 elsewhere.
Even if the US switches to 100% renewable the problem is far from solved. Look at the population pyramid of Nigeria, for example. Those people will want homes (cement, steel) and cars and flights.
I think I understand where you're coming from, but I would say 'don't let the perfect be the enemy of the good'.
Grand jumps in capability rarely (if ever) happen in the real world.
Gradual change can feel like a capitulation, but it's often the safest and best overall.
If you try to force huge change and fail or things go wrong or the system is deficient in some way, there can be a big backlash.
The CO2 released in production and deployment of solar cells is regrettable, but as soon as that solar cell comes online it starts displacing fossil fuel.
