I don't think that moving the generation around is really an "instead", because the problem at hand is that distribution is expensive and someone has to pay for it if you want a grid. And most of that cost is the local stuff.
So how do you get everyone connected that wants to be, without it costing them a ton of money? You might have to make the grid cost into a mandatory tax.
Whether the electric company is private or state-owned is mostly a separate issue.

Germany has a long history of public opposition to nuclear power, going back over 50 years, and this is related to environmental concerns, safety concerns, and the association with nuclear weapons.
Both the USA and the Soviets had nuclear weapons deployed on German soil with the potential to be directed at the German people and this cultural and historical context is important to understand the current policy landscape.
The origin of the popular Green party in Germany is deeply connected to the peace movement and anti-nuclear activism that pre-dates concerns about climate change.
It’s fine to disagree with the policy decisions the German people made, but it’s good to understand the reasons why they made them.
Hyde Park is about 1.4 km2, so that would be 70 km2, which even in a dense country like the UK is not that much. It seems like a no-brainer to go for solar instead.
The phrase "green energy transition" is mentioned only in the headline, and is completely irrelavent to the point being made in article, which is that unregulated mining in poor developing countries is bad.
