Yes, and no.
Yes, replace all FF generating capacity with non-FF alternatives and you can then price electricity accordingly. I'm really not going to respond to any comments on that statement. It's just not going to happen overnight, but I think we all agree on that.
No, because while we are interconnected and other countries use gas (bought on that global market) we are beholden to the price of electricity of those other countries.
Don't misunderstand me, I believe we should be investing to remove our dependence on using FF to create electricity, or find ways to remove the harm caused by using FF. There is no silver bullet, but it does not preclude us from doing what we can while remaining economically viable in a global economy. It's not easy.
Out.
