Scotland's renewable energy output increased by 45% in the first quarter of this year, compared with the same period last year.
UK government figures showed Scotland generated 4,590 gigawatt hours (GWh) of renewable energy in the first three months of 2012.
This was an increase of 1,435 GWh on the first quarter of 2011.
Scotland is aiming to generate the equivalent of 100% of its electricity needs from renewables by 2020.
The UK Department of Energy and Climate Change also issued revised statistics for 2011 which showed that renewable electricity generation in Scotland was 13,735 GWh in 2011, an increase of 44.3% from 2010 and up 97.3% from 2006.
The Scottish government said that, assuming gross consumption in 2011 was similar to 2010, about 35% of Scotland's electricity needs came from renewables in 2011, beating its interim target of 31%.
'World leader'Scottish Energy Minister Fergus Ewing said the figures showed the country was making good progress towards the 2020 target.
He added: "The increase of 45.5% in renewable output in quarter one 2012 compared to quarter one 2011 is particularly encouraging when you consider that 2011 saw the highest output from renewable energy to date.
