Before the famine your average farmer family ate a little pig a little poultry - and they had perhaps one cow - and potatoes, potatoes, potatoes (tillage became necessary with the rise in pop) and not scampi, sushi, yoghourt, crisps, tuna, veal, salami, kiwis, zuchini, etc. etc.

200 k bpd and pop. 4 mil. is .05 barrel a day pp, for Ireland. That is not far below the US, which clocks in somewhere between .06 and .07. Very rough, obviously, just to say that the difference is not tremendous.

I read somewhere that in Ireland 7 out of 10 workers drive to work, which is a perhaps a lot in EU comparison? The important point though is that Ireland burns a lot oil to produce electricity - oil is its primary energy supply (about 60% : EU27 average, 38%).

Ireland uses mostly natural gas for electricity production (about 60%), then coal, and some heavy fuel oil and distillate. Peak Oil will affect the motorist obviously, but not electricity production, unless of course, the supply of gas dries up, or price of gas rockets. The gas comes in from Scotland, and ultimately from Gazprom in Russia I guess...
We are very vulnerable to external shocks.
Also, Ireland's urban planning seems to be based on Los Angeles or something. It's a gigantic big sprawl. That's why most people drive - because they have to.

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.
