Seems very unlikely it'd take 50 years to double the number of power plants. Yes, things take a lot longer now than in the 50s, but it's still at most a decade

Seems very unlikely it'd take 50 years to double the number of power plants. Yes, things take a lot longer now than in the 50s, but it's still at most a decade to build one unless its nuclear. And it can be substantially sped up if there's a pressing need.
