I'm a huge proponent of trying to build solar microgrids in as many places as possible; a system where every small municipality has its own local solar microgrid with battery storage, each self-sufficient but patched into a much larger grid that can help balance load and smooth over local failures in eachother's microgrids would be a way to allow the highest level of energy independence possible and avoids the pitfalls of centralization while still getting the benefits of a large-scale grid. It could be an incredibly resilient and sustainable system if well implemented. The only barrier to it as it stands is the cost to install all these solar panels and batteries.
