Losing 20% of your electricity supply is a calamity, not an annoyance. So unless you want the calamity, you're still dependent on imports.

Personally, I don't see an issue with that, as long as the neighboring countries you're importing from are reliable and will be able to supply at the times you need (i.e., they don't have the same possibly spiky import dependency as yourself). The other option is massive storage capacity.

I just don't think it makes sense to just equate renewables with automatic sovereignty.

Dunno about you, but losing 20% of my electricity supply is an annoyance. I just don't run the clothes dryer and hang my clothes on a rack instead.

(And yes, I have solar + battery, and have lost 100% of my outside electricity supply on a half dozen occasions since having it installed, and my actual response has been to not run the clothes dryer.)
