Distributed solar is good for each of us - and it might give us hands on experience with this technology, and even provide a minimum base for keeping the lights on, so to speak.
But nation states require control of major energy, and this is an imperative for them.
It is a fundamental requirement that only 'they' can afford this - this is reality.
Space-based solar, for example, or large facilities of a size comparable to a giant hydro-electric dam or coal or natural gas electric plant.
Both a distributed and state controlled mesh are hopefully in our future, if we have a future that is, which is highly uncertain.
We need the resources in the solar system now - both energy and material - and we need both of these to survive in the long term.
Conservation and simplification can only buy us time - they are not a 'sustainable' solution.
There is no stasis in the Universe that I have studied all my life - it would be a catastrophic mistake in thinking to even imagine that we can create some type of 'steady state' here on Earth.
Forward - or extinction.
