Penguin are one of the most notable publishers in the world.


It came out last year. The author headlined the National Sustainable Festival.

His credentials are top-notch.

Its forecast is for 2020-2050. A lot of research has gone into the book. If you can point me to a more current source, I'll happily check it out and report back.

As for household solar: 25% have panels as of 2017.
"1% of Australian households claiming to have plans to buy or replace their solar panels in the next year."
Seems near saturation to me.
