Some countries are outright hostile to "green" energy, and some are so deeply dependent on foreign gas/oil that they haven't invested in switching over to a more diverse supply.

I doubt most countries are as detailed as places I've lived in the US (Oregon, California, Washington) where I can look up exactly what type/% of resource was used to produce electricity.

Fingers crossed that this Russia debacle pushes Europe into a greener energy posture without much pain for its people over the next few years.
