They'd be better off with (and are building out) offshore and onshore wind. If you've ever been to the west coast of Ireland you'll know they've got almost unlimited wind energy. The country is targeting 5GW of capacity by 2030 and 37GW in the distant future[1].
If only they could harness the power of rain, Ireland would truly be an energy superpower.

Are they selling to UK that AFAIU stopped building wind 10 years ago. Regulatory advantage...

I know this is in jest, but that's basically "dam up some valley rivers and put a hydroelectric generator on the end", and unfortunately Ireland isn't so good for that. (It's not just the physical geology, it's also all the people living in the places you'd flood).
Hydro as a battery is easier and works in far more locations, but that's not harnessing the power *of rain*.
But yes, Ireland and the UK have an absolutely huge wind power resource available around them, IIRC enough to supply all of Europe if the grid connections were there to export it all.
