They are blessed with all three of hydro, geothermal, and wind.

Do we have many countries around where wind is not a thing?

And sun isn't uncommon. I was chatting with a person in Auckland, NZ. He said it was a cloudly day and he was producing much more solar power than he needed. His take: the panels are the cheapest part of the system so they just over-provisioned. We can all do that - it aint hard

Our rainy day production is still a fifth * of our peak in Kerala, India. Wish all inverters support 5x overprovisioning, current ones support 1.5x and suffer lower life. Seems 1.1x is the recommended provisioning guideline.

* UK internet stranger said he gets negligible output when it rains

Thanks for the feedback about inverters - I was unaware.

I'd imagine quite a lot of smaller ones don't have anything. Take a look at https://energy.usgs.gov/uswtdb/viewer/ and notice that huge swaths of the US have almost no wind turbines.
