They already are. Scotland has hit 100% renewable energy already on a few days.
No, it’s not false, that article takes a deliberately obtuse definition and uses it to debunk something which wasn’t claimed.
Clearly due to the nature of grids and shared generation nobody can guarantee that all electrons used came from wind power (nor does anyone care!?!) but Scotland is an exporter of energy and at times its entire needs could be met from its renewable generation.
Not sure which part of Scotland producing lots of renewable energy you find difficult to cope with, but renewable production is here to stay, cheaper than other sources and a growing part of the mix.
Even if you didn’t believe in man-made global warming, surely the idea of cleaner Scottish air would be a bonus.
