The head of EirGrid, which runs the State's electricity transmission network, has said it is possible that 75% of electricity will be generated from wind in the future.
Chief executive Dermot Byrne said a Government target to produce 40% of electricity from renewable sources by 2020 could be surpassed.
Mr Byrne was speaking today at an Oireachtas committee. He described the 75% figure as 'truly staggering', but said it could be reached.
He also said a milestone was reached last April when, for a time, 50% of electricity was being generated from wind power.
