Gah! One of their reports within the past 5+ years. It was in an analysis of risks by major energy modalities. Unfortunately IPCC's content organisation is a disaster.
Analysis unit was deaths per GWh or similar.
I'll see if I can find it though I'm not optimistic.
Our World In Data posts similar stats, premature deaths/yr at 1 TWe/yr generation:
Coal: 25
Oil: 18
Gas: 3
For the safer options, statement is inverted, as years for 1 death:
Nuclear: 14--100
Wind: 29 years
Hydropower or solar: 42 years
Solar: 53
Note w/h/s are all within the range of error for nuclear. (And why hydro isn't broken out separately I don't know.)
This is very similar to nuclear.
> Per IPCC, wind and solar are very nearly on par with (possibly better) than nuclear.
Mind sourcing this? every place I've looked shows nuclear beating solar by 5x and wind by 2x.
