While it would be nice if all the required nuclear or storage was installed decades ago, (1) we don't need to do this transition overnight, (2) a decade is on the optimistic side for rolling out new nuclear on this scale so it's not much of an improvement in that regard, and (3) most of the existing power infrastructure can be kept running until the batteries are available, and we get to keep looking at storage supply in the supply is still growing appropriately for the targets.
