I agree that we should invest in both. But it is not as easy as waving a magic wand. Energy project development is a complicated dance between local power market regulators, local and federal incentives, private investors, and shovel ready/cost-effective technology. And in the rare occasions when congress opens up the wallet, it is a small pie that everyone is fighting over, so the lobbyists start slinging arrows.

The fact is, nuclear can and will be a really great addition to the energy mix. But there are models out there that show that we can build a carbon free grid without it. The big question mark is on the future cost of storage. The consensus is that those costs are going to come down considerably. If so, then going all in on renewables likely gets us to a carbon free grid faster. But this is also a very US centric take. For example China likely has much easier road to rolling out nuclear (less regulatory hurdles, less local interference/input). Where as in the US, I am sure we can build a big national pro-nuclear movement, but the second someone proposes a real life project, the NIMBY's will come out of the woodwork.
