The amount of electricity generated in Scotland from renewable energy increased by more than 15% last year.
Figures from the UK Department of Energy and Climate Change said Scottish renewable energy generated more than quarter of the UK's green electricity.
The figure for England was 65%, 6.1% for Wales and 2.5% in Northern Ireland.
Across the UK, renewable energy generated nearly quarter of all electricity output. It was less than a fifth in 2014.
The fastest growing element of green energy was in solar photo-voltaic cells, increasing production in Scotland by more than one third to 193 gigawatt-hours (GWh).
Across the UK, solar power production was up 87% to 7500 Gwh, yet that was after delivering only around an eighth of the potential from its installed capacity. That rapid output growth was also despite a fall in hours of sunshine.
Output from wind turbines in and around Scotland was up by 21%, partly due to more wind during last year than in 2014, and also because of a 5% increase in installed capacity.
With output reaching 30% of potential capacity for installed onshore wind turbines, Scottish output reached 14,100 GWh, out of a 22,000 GWh green output in total.
Onshore wind from Scotland represented more than two-thirds of the British total. However offshore wind, almost all of it from turbines located in the seas off English and Welsh coasts, is now producing more energy than Scotland. There is also more British biomass output than Scottish wind power.
There was growth in output from biomass burning in Scotland, but it was offset by lower electricity generation from landfill gas and sewage sludge digestion.
