> Ultimately though, the only way to fix this is to build a lot of wind (industrial scale) and solar (residential scale) as otherwise we're at the mercy of world events.

I'd add that this is only part of the equation because: what do you do on an overcast day with no wind?

You need significant storage capacity before you can become isolated from world events. Until then, you need power generation that you can bring online on short notice: coal, gas, hydro, etc. Traditionally, gas was used for this because it's easy to store, quick to get going and gas plants can also burn coal if needed.

Unfortunately, the nice properties of gas (easy to store and transport) mean that it's a global commodity. It will go where they pay the most, which means that far away events can cause a price in gas prices globally.

Battery technology is really, really getting there.

And in the absence of any more improvements here (unlikely) you integrate your grids with other countries. That's harder for Ireland, but it's still worth doing.

Does this battery technology grow on trees in Ireland, or does it exist in a foreign (and perhaps one day adversial) nation, like China?

The sheer number of people in this thread saying, "we need renewables to be independent!", from countries that don't actually manufacture anything, is astonishing.

There's at least as much battery production of batteries in Ireland as there are viable coal mine sites.

And crucially batteries aren't fuel they're storage.

Also all these economies do make stuff, they just don't employ huge numbers of semi-skilled workers to do so. Most of the factory jobs are gone, but the factories are not. I live in a port city, about a century ago this city had loads of jobs crewing ships and loading cargo but today more work is done by a tiny fraction as many people.

Is Ireland going to burn the batteries after they buy them from China? If China says "Do what we say, or else no more batteries" then...nothing bad happens. Ireland's batteries continue to work.

Coal or gas on the other hand...anyone can cut off Ireland anytime.
