They said it couldn't be done, but you don't tell a Scottish engineer that when there is money-saving technology to deploy. So if the UK Brexits from the EU, and Scotland secedes from the UK, how will they manage cross-border sales to England? Iceland has some ideas for using extra power. As do Australia and North Africa.
In the first half of 2019, Scotland generated enough energy from wind power to supply its homes twice over. Specifically, turbines generated 9.8 million megawatt-hours of electricity between January and June, enough to supply power to 4.47 million homes – not bad for a country that has around 2.6 million homes to its name.
OK, that's not the entire economy, but take a look at this.

Wind power in Scotland—Wikipedia
Wind power in Scotland is the fastest-growing renewable energy technology, with 8423 MW of installed wind power capacity as of December 2018. This included 7800 MW from onshore wind in Scotland and 623 MW of offshore wind generators.[1]
There is further potential for expansion, especially offshore given the high average wind speeds, and a number of large offshore wind farms are planned.
The Scottish Government has achieved its target of generating 50% of Scotland's electricity from renewable energy by 2015, and is hoping to achieve 100% by 2020, which was raised from 50% in September 2010.[2] The majority of this is likely to come from wind power.
Scottish Power plans major expansion of onshore windfarms
Nov 24, 2019 - Renewable energy giant says it expects Tories to reverse their block on onshore generation.
Och aye, mon, what'd ye expect from Sassenachs?
The UK as a whole is on a roll as far as renewable energy is concerned, because it just managed its longest stretch without relying on coal power since the Industrial Revolution of the 19th century.
Coal power stations didn't supply any energy to the grid for seven days in a row, according to the National Grid in the UK – a total of 167 consecutive hours. Gas turbines, nuclear power, solar energy and other renewables all played a part.
Ah, weel, mebbe I was a wee bit harsh there.
Orkney is using excess wind power to generate hydrogen. One application is their ferry from the mainland.
