Scotland is already near 70% and aiming for 100% renewables. With sufficient storage capacity (hydro and batteries), there's no reason any country couldn't be 100% renewables.
Biofuels are a very small part of the mix, and I agree pretty pointless except on a small scale in remote locations to provide heat as well as power.

>> "Scotland will soon be meeting the equivalent of 100% of its electricity needs from clean energy sources."
This is kind of a weaselly. Two parts of this sentence need explanation: 1) "equivalent of" 2) "electricity needs"
The equivalency is a murky way of saying that they still use fossil fuels but are also engaged in carbon offsets to reach the equivalency. Those carbon offset methods are sometimes dubious - paid someone to plant trees in the amazon, etc. Further, do we really consider burning biomass clean or renewable (I would not)?
The "electricity need" stands apart from the country's heating and transportation needs, at least. So this is a fraction of a fraction of Scotland's energy needs being met by "clean" energy, if you consider the net return of solar and tidal to be worth more energy than was consumed in manufacturing, transporting, installing, and maintaining those facilities before their respective end-of-life.
