Right, but nuclear remains far more expensive than wind and solar, which is why almost no new nuclear gets built.
I'll also note that a chunk of the data is from 2007 and 2008, and the price (and greenhouse gas emissions associated with) both wind and solar have declined markedly since then.
Yeah, wind and solar seem to be able to go for 50+ years too. The main reason they're not doing that so far is that newer installations can kick out more electricity (and money) in the same footprint.
