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