"these solutions are absolutely affordable, especially given the sinking costs of wind and solar power."

That's all it says for cost, sure you can call it affordable if you want but I can't afford the cost of Solar on my home, and it's crazy to claim it's affordable to build out a network for the entire country that isn't going to cost a lot to roll out, and by a lot we're probably talking trillions. I already have to cut back on electric use because I'm now paying more and more every year for a nuclear plant I didn't ask for that is a hundred years behind schedule with skyrocketing costs.

I like the California approach by requiring it on new construction though and would support that anywhere.
