This is a bit of a weird list. This looks at the percentage of electricity generation that is renewable. But some of these countries are net importers. I think the final row in the table from the report [1] is more interesting. It compares the generation of renewable energy as a percentage of demand. There are quite a few countries that don't quite have 100% renewable generation, but generate way more than 100% of their demand as renewable energy.
