On then 23rd October, the head of AEMO explicitly told the Senate Committee On Energy Planning that Bowen's claim that reduced prices would occur via the 82% renewables scheme "could not be guaranteed". It is never going to happen.

The ability of wind and solar to manufacture their own replacements is just one of several myths. As we speak politicians are dismayed by the fact Whyalla steelworks is not powered by solar hydrogen. Thence to make more solar and steel etc. Another myth is that adequate wind and solar will not be a blot on the landscape with new power lines, wind farms and spoiled views.

Then there's the combined system cost with batteries, frequency correction, gas backup and so on. Supposedly cheap wind and solar are just a fraction of that total cost. In my opinion humanity's greatest crisis is not global warming but when we can no longer afford depleted oil and gas. Almost every mouthful of food we eat is grown, fertilised, harvested, processed, packaged and distributed with the help of oil and gas. What happens when there is no longer enough?

I agree with most comments here but all statements effects are
distorted by that people never take into account that the oil companies
are planning their way out of the oil industry.
Only Shell and BP have said it out loud.
At Royal Dutch Shell's AGM at the Hauge in 2017 their ceo announced the
company had formed a group to study how to leave the industry.
BP changed its name to Beyond Petroleum.
Shell has sold its business in Germany and the UK to Octopus.
Royal Dutch Shell has been wound up and all Shell assets world wide
have been folded into Shell Ltd registered on UK share market.
The reason given is that the cost of discovering new oilfields and then
developing them is so high it is not just worth it.
No doubt governments like ours just added to it.
You will notice that Caltex and Shell in Australia are changing to Ampol.
So there is no argument in comparing electric car manufacturing with
anything else. The motor companies no doubt got the message from the
horse's mouth and realised they had no choice.

Taswegian,
Well stated !
