Here in our little town in Alaska where we have a micro grid we switched from fossil fuel power to renewable, the cost was cut in half and the power outages were reduced in duration and number.
A lot of things work on a small scale but not on a larger one.
What is the backing store for your grid when the renewable power is insufficient for demand?
From my POV I think the intermittent renewables are way insufficient unless & until they have a reliable backing store of at least 24 hours on full load. At present this is a fantasy unless you either have hydro power, nuclear or fossil fuel plants.
Happy to be corrected but I'd want to see examples on a realistic (say 1 million population centre) basis. And with a decent mix of residential, light industrial and commercial.
