Specifically Albania, Bhutan, Nepal, Paraguay, Iceland, Ethiopia and the Democratic Republic of Congo.

Not to downplay the positive steps that are being taken towards using renewable energy worldwide, but one must point out that all those countries except one are almost exclusively using hydroelectric power, whose availability at such scale is a geographical lottery. As for Iceland, which also relies mostly on hydroelectric power but not in such great a proportion, it makes up for it thanks to easy and abundantly available geothermal power (which, though environmentally friendly, is arguably not technically renewable).

Geothermal is powered by fission Uranium and other heavy atoms deep in the Earth.

Solar is powered by fusion of Hydrogen in the Sun.

I'd use the same classification for both.
