something about solar I don't understand is even if you crack energy storage for nighttime, what do you do about the tail risks? There are overcast days, sometimes it lasts for multiple days. you can have a volcano eruption or wild fires that have the same effect on solar cells.

would it really be acceptable to have power outages during such events? is it reasonable to have gas plants on standby for just this? if so, you must add them to the cost of solar.
