Hello Liciferase, I am still reading that document to which I referred.
Areas like energy, food, banking, health etc are referred to as HUBs.
The author shows how cross contamination between HUBs occurs and that
is the risk our politicians are taking on the way they are going.

They run the real risk of collapsing the whole economic system of
the country if they get it wrong. Just in Time Supply is the trigger.
We need a guarantee that they will have 100% backup in place before
making any decisions on power systems.
If it was up to me I would restart Hazlewood except for one unit and
refurbish that unit completely then do another one and so on.

The risk is 100% unemployment and starvation if it comes to the worse.

Coal has had its day Bazz. Hayzelwood is stuffed.
We would have starved to death months ago if Abbott had his way.

doog, when the lights go out you will hear a different refrain.
Coal here has a while to go yet, but eventually it will leave us.
We have to be ready for that time but we are obviously not yet ready.
Peak coal has already occurred in the US and some other countries.
A premature closing of coal mines and coal fired stations will prevent
us making a controlled conversion.
Finkle's battery backup plan appears to be unaffordable.

Bazz so was the NBN apparently now we have to settle for a lesser NBN.

Eh, NBN ?
What makes you think you were going to get the speed that was promoted for it ?
