Interestingly, Eigg, a small hebridean island off the west coast of Scotland has been operating 95% of their power on renewables since 2008: https://islandsgoinggreen.org/about/eigg-electric/ (they keep diesel to drive baseload backup)
The initial reason for this was that to get electricity from the grid to them was going to cost _lots_ of money. Solar is an important part of their mix - the Hebrides get a a good chunk of sun in the summer (and long days too). They've been a case study for a number of similarly isolated communities - either islands or other locations far away from existing electricity infrastructure.
Making batteries more efficient (and cheaper), and making each of the renewables mix more efficient and cheaper will make this possible for more and more communities.
