According to figures produced by Eirgrid - the state agency for managing the national grid - there is now enough green energy connected to homes in Ireland to supply 600,000 homes.
1,034 MW of electricity supplied to the grid, now comes from green sources. Each megawatt of electricity is enough to power 650 homes. Wind energy accounts for 75% of all renewable power generated. 9% of electricity produced last year was from renewable sources.
Wind energy capacity has increased from 170 MW in 2003, to a current capacity of 781 MW from 71 wind farms throughout the country. Another 450 MW is expected to be launched this year and it expects to sign deals for the provision of a further 1,300 MW by the end of the year.
Green energy is also supplied from hydro projects and burning landfill gas from waste.
