WWF Scotland director Lang Banks said: "These figures underline the importance of low-carbon businesses to Scotland and the rest of the UK, by helping grow our economy and creating jobs.
"However, if we are to enjoy the multiple benefits of the transition to a zero-carbon future, we need our political leaders to commit to a renewable energy future by bringing forward the policies to realise our potential."
He said Scotland could become the EU's first fully renewable electricity nation by 2030, but only if Scottish ministers committed to the shift and ensured their forthcoming energy strategy focused on renewables, reducing demand and developing energy storage.
