> Solar added about 600 terawatt-hours of generation globally

> And nuclear is making a comeback: More than 12 GW of new reactors began construction in 2025

Am I reading it right that growth in solar was 50000x that of growth in nuclear? (And those reactors of course won't be finished / online until some years into the future.)

No, you are comparing watthours to watts. At 90% used factor 12GW would be ~95 TWh.

More over that 12GW is start of construction. New commissioned nuclear is 2.7GW in 2025 and 7.4GW in 2024. 2024 is probably an anomaly.

ooh, of course, thank you

[ZeroGravitas]

No you're wrong, the nuclear "started construction" and so solar added infinitely more generation than the zero they will generate this year/decade.

The world did add 3GW of nuclear generation in 2025 but it also closed 3GW.

I made the same gut assumption, and it points to either poor writing, or deliberately misreading writing that they mix units like that in the same paragraph, where presumably the idea is that we get a feel for growth in both?

Its probably nitpick correct, because the 12GW is planned capacity, while the solar might be measured use? but simple assumptins or conversions, as another comment points out, get you comparable numbers. taking the title into account, the whole article is a little bit smoke and mirrors on clear communication, despite having plenty of numbers. Thats a shame because it sounds like even unvarnished its good results!
