The "three ones" as a former GS VP explained to me once.
You can build a one-gigawatt natural gas plant in one year for $1B. Compared to nukes that's real cheap. And thanks to fracking NG is real cheap. And there is no risk, no need to build on spec , no need for patient capital, waiting for two decades for a return while biting nails for an NRC license, a market for your electricity, or an NGO putting you out of business because Hilary got elected.
It isn't ideology. It's pure simple straight risk-informed profit motivated economics.
That's an elegant way of putting it. [mental note...]
