> We don't measure capacity in GWh

I cannot even express how much hatred I have for bad charts, and getting tricked by one anyway when I go in already expecting it to be lying to me is incandescently indescribable.

On Wikipedia there's a very progressive-looking chart that is measuring in TWh/year and going up up up. And as you say,

>Ireland lacks any energy storage so none of that wind can be used for baseload

You always measure baseload in GW or if you're fancy, TW.

So what that chart is really saying is that Wind is adding on average about 70 KW of capacity per year, when amortized over 24 hours. Which is probably on the order of an additional .3GW of capacity per year when the sun is shining and bupkis the rest of the time.

Although given how overcast that region is, maybe measuring solar in TWh/year is a bit excusable, and then they end up measuring everything else that way?
