AD Australia reaches record 36.8 pct renewables in 22/23, lowest coal this century, page-35

@LoadedDog (Reply on the blink AGAIN!)

That's apples and oranges.
if Coal is free then Solar and Wind are also free.
Theoretically, SH2 will pump off Renewables and/or excess fossil.
it's electrical efficiency (estimated) is 75%.
The comparison should be between the energy generated by burning the Coal and the electricity output at the generator.
Not sure what that is, but It's probably below 75%
