The number of students on renewables-related courses in Scotland has soared by 70% in just four years.
Scottish Renewables has found that 22,000 undergraduates were studying subjects which cover the sector, ranging from engineering to maths.
The same survey in 2019 reported around 13,000 young people studying in similar areas.
Scottish Renewables said this rise demonstrated the attractiveness of the industry.
The figures come from a Freedom of Information (FOI) request to 33 colleges and universities.
The BBC says the research also showed the sector is dominated by men, as only 28% of students are female.
Commercial graduate
Ellice Mentiplay is now a commercial graduate with EDF Renewables in Edinburgh.
The 24-year-old was born in Perth, but her father's job in oil and gas meant she lived across the world before finally returning to Scotland.
Her degree at Abertay University was in environmental science which she followed with a masters in energy, society and sustainability at Edinburgh.
On wind energy, she said: "I think offshore, particularly in Scotland, is just going to be huge in the future especially with developments into things like floating offshore wind.
"I wasn't really aware when I was younger that this was a job career path that I could go down.
"Working in renewables means that I can also help the UK transition over to clean net-zero energy."
Billions to the economy
Scottish Renewables said wind, solar and hydropower already provided the "vast majority" of Scotland's electricity, and contributes billions of pounds to the economy.
From the FOI figures, the most popular courses are engineering with 5,373 students followed by business and management.
The institutions with the highest number of students studying renewables-related courses are Glasgow Caledonian followed by St Andrews and Glasgow.
A report by Skills Development Scotland found that in 2021 there were about 100,000 green jobs. But it said identifying the true number was difficult for multiple reasons - not least because there's no formal definition of a "green job".
Some work might be directly linked to sustainability or renewables engineering whereas others might have greener elements such as a plumber installing heat pumps.
Johnjo Morgan, 23, is in the second year of a three-year apprenticeship in automotive engineering.
Dream job
He landed a dream job restoring classic cars at Errol in Perthshire.
One day a week he studies at Dundee and Angus College on a course which includes working on electric vehicles.
He has noticed an increase in people converting older cars to run with battery-powered electric motors.
Johnjo explained: "It's grown in the last two years. It didn't exist and now everyone's starting to hear about it, so I'd imagine it's going to get bigger and bigger.
"Older cars were more interesting with petrol and diesel. The engines were more interesting but they're of their time. The future is definitely electric."
