Because at the moment wind has been the winner in the Irish climate, especially when you look backwards long enough to account for the time scales over which energy buildouts occur. Renewables have grown to 40% of the overall supply, resulting in the most expensive plants (currently coal plants, and before that peat) closing. Solar is entering the market rapidly though, it grew from like 1% to 4% in the last 3 years. So I wouldn’t be surprised to see some gas plants closing in the next few years, given the more expensive options are now already gone

That rule is a rule of free markets. Electricity is not a free market, so it only partially applies. Texas is closer to a free market, and unsurprisingly it is adopting solar faster than most.

It is. But solar produces most around midday and then tapers off toward dawn/dusk, so it might supply 100% of demand at midday but only 10% around sunset.

If you build more solar it'll meet 100% of demand for a larger portion of the day, which is what we're doing.

Solar is best used to take care of peak summer demand. It’s not gonna displace coal plants which tend to make up base load.
