Below are the retirements so far in 2025...
Note: Many capacity retirements and additions occur in the last month of the year, so this is not a complete picture for 2025.

The September Electric Power Monthly is out from EIA.

Looking at the Capacity added to the US grid so far in 2025, we can see that almost 90% comes from Solar and Wind.

A recent EIA article said:
"Although natural gas generation still provides more electricity than any other source in California..."
This is incorrect. If you include rooftop generation, solar is now the largest source.
Q1-Q3 2025
All Solar = 73 TWh
Gas = 54 TWh

Spain looks a LOT better if you consider all Clean Energy.
One missing element for Spain is battery storage - but it looks like growth in this area may accelerate over the rest of the decade.

BESS will allow Spain to increase solar share by at least another 10%.

Interesting to see that solar now shows up in second place for hourly fuel share across the US.
Currently, only a few hours a week, but let's see how this changes over the coming years.

2) Poland has plans for three nuclear reactors to come online in 2036. In the meantime, they should continue to rapidly build out their home-grown wind and solar.

Poland could easily have 2/3 of its electricity based on solar/wind BEFORE nuclear joins the party.

Below are some numbers supporting John's comment.
Also:
1) Solar/wind are faster than demand - big deal!
2) Nuclear will start contributing more during the rest of the decade.
3) If China has a down year economically (2025/2026), clean energy will displace a lot of coal.

New record for solar on @californiaiso.bsky.social - CAISO
Solar generation goes over 20,000 MW for the first time!
New record = 20,818 MW at 10:55 am on April 11th.
A big jump from the previous record - 19,624 MW.
Note: demand at 10:55 am was 19,217 MW - so solar provided over 100% of load!

Ric,
I am on the road - and was "off the grid" so to speak 😀 earlier.
It looks like prices spiked between 8:35 and 9:20 am - I am not sure why.
Batteries were still discharging, and it looks like they did respond somewhat - note the bump starting at 8:45 am in the @gridstatus.io chart below.
