For Ireland, it's not so much the sourcing of fossil fuels, but the imposition of political taxes on fossil fuels onto consumers.

About 50% of the retail price of petrol in Ireland is tax (excise + carbon + VAT).

Overall fuel taxation in Ireland is ~50%, compared to 15-20% in the US. Although to be fair, most of Europe is doing the same thing to its population (during a cost of living crisis).
