My opinion is that to be truly decentralized we should do both. Not just physically decentralize by location, but decentralized in a sense of having multiple options. We should do solar, and wind, and nuclear power. The power output of solar and wind is just not where it needs to be to replace both nuclear and fossil fuels, so I do have to argue in favor of building more nuclear power, but that doesn’t mean I am against building any other renewables as well.
