Seemingly just in time, solar, wind, and storage are scaling both in production capacity and in falling costs to solve our climate problems. These will be the backbone of getting to 80% carbon free electricity in the next decade, and 0% carbon not that long after. This will be far cheaper than any other source of energy generation we can use, and will save us massive amounts of money.
One of the better grid modelers out there, Christoper Clack, who has no opposition to nuclear and in the past has made strong arguments for it being a cheaper way to get to 0%, also has an amazing new mode out this year that says we should do something very unintuitive: deploy massive amounts of distributed solar and storage close to power meters (e.g. on people's homes). This will result in a much stronger distribution grid that can both shave peaks of demand, resulting in far less very costly distribution infrastructure, and which will empower far even cheaper deployment of larger amounts of utility-scale solar and wind in future decades.
Nuclear would be nice if it weren't so expensive, and if it were our only option we should keep it around, but there's little reason to create make-work when we have cheaper options, and options that will have additional benefits for the grid such as greatly increasing reliability and resilience. Massive distributed solar and storage will create an absolutist rock solid grid that will be able to weather disruptions far better than one with large generators that become almost like single points of failure.
