Yes, the money matters when it's private industry putting it up.

If the government could do the smart thing and enact a carbon tax so the true cost of carbon based fuels could be accounted for, this problem would naturally go away with no need to convince anybody of anything else. Nuclear would maybe be viable, but at the very least building new solar and wind would become cheaper than just operating existing coal plants.

Maybe it's not politically popular? I don't know. Taxes automatically reduce the thing being taxed, but we tax good things like income, rather than bad things like illegal drugs, gambling, pollution, garbage, etc. It makes no sense, but that's why I'm a programmer and not a politician.
