Can someone point out where in the CSIRO report they account for wind and solar generation having an effective life of something like 15 year before requiring replacement? Ergo, wind and solar will require replacement at least twice, and possibly three times, before a new HELE coal or nuclear plant will require replacing.

(I did note, however, they assume a useful life of base load power of some 30 years, as opposed to an expected operating life closer to 50 years).
