But this source Think Progress states this.....
Even for the U.K., Scotland is a green energy leader. As of September (2014), the country got 29.8 percent of its electricity from renewables, 34.4 percent from nuclear, and only 34.4 percent from fossil fuels. Scotland hopes to generate the equivalent of 100 percent of its electricity from renewables by 2020 and to export non-renewable production from conventional power plants to countries like England.
Considering that this is coming from a lefty source (Think Progress), even that % is probably exaggerated. I wonder how much of the 29.8% is actually generated from standby sources that kick in when the wind doesn't blow.
Also, renewables include hydropower in addition to wind and solar. If it is as much as 10%, I'd be surprised.
