Ireland uses mostly natural gas for electricity production (about 60%), then coal, and some heavy fuel oil and distillate.

Source please, thank you. (As that is not at all what I gathered from the few reports - Gvmt. - I read - admittedly these often date from 2003, 4, 5..)

(It is true that nat. gas has replaced oil in some measure in the past 7 or so years.)

Look at the publications from http://www.eirgrid.com, Ireland's transmission system operator, particularly the Generation Adequacy report for 2007-2013 (page50). In 2013 about 60% of the generators will run on natural gas or distillate oil - depending on which is cheaper. This is pretty much the same as now. About 20% run on Coal or heavy Fuel Oil, then a small amount on purely distillate oil, plus about 10% hydro and some peat and wind.
