Renewables statistics realities : Comments

By Geoff Carmody, published 11/7/2018

These average capacity multipliers will also multiply total costs of ensuring reliable power even as $/MWh renewables generation costs fall.

Luciferase, don't forget the other imbeciles as well.
The greens.
By the time they've all finished patting each other on the back for making absolutely unrealistic suggestions about renewables, and not one ounce of viable results to support their misguided, mis-informed agenda, we will all be well and truly stuffed.
We have only to look at where we are now, with some of the extortion prices for electricity compared to other countries.
The presence and the performance of the greens so far is a clear indictment on them being an irrelevance.
They have no viable experience and knowledge in the world of renewables.
They just talk a lot and cherry pick examples of what they deem success stories of renewables, but look a little closer and you will find massive numbers of performance errors.
The science in most cases have been theoretical.
The modelling has worked in the laboratory and on scaled down, tightly controlled and monitored pilot plants.
In the real world and at full scale they are a failure.
Just like the storage system (batteries).
The greens are nothing but a menace and should be removed from parliament.
They are not a political party, at best they are a lobby group, trying to push a failed agenda.

I don't believe AEMO has any idea, at all, of what level of storage is needed to buffer intermittency of renewables sufficiently to deliver 24/7/365. That is reason alone not to embark on a path towards storage as a solution to AGW mitigation. There was a wind drought in the UK recently and without nuclear it would have been a dire the situation. How much storage is enough, does anyone know?

It's hilarious to suggest industry should keep an eye on the weather to shape its activity. I can't get over the thinking that we should revert to some seasonal, agrarian view on how industry should adapt to meet the ideological imperative of imbeciles.

Luciferase, It all seems so obvious and straight forward to people like us.
I cannot come to terms with the fact that the majority of the public can be so ignorant or arrogant, either one or both, that they seem to refuse to want to believe that things are hardly ever that easy in life, and that the govt IS actually out to enrich themselves on the back of these totally unworkable things called renewables.
One day we will get more honest than dishonest pollies in Canberra, and then maybe we'll start getting the truth for once.
Any child can tell you that renewables work, but not at the size and scale required to keep pace with or exceed the old tried and proven methods. ie; coal, gas, and nuclear.
Once the greens stop lying and overstating the impact of fossil fueled power stations we might get back to concentrating on bringing the price down.
As for this pathetic attempt at trying to con people with the Snowy II joke.
I refuse to believe that both the people and the pollies are so stupid that they can't see through this con of calling Snowy II a Hydro-electric power generator, implying that the thing is like Snowy I.
It isn't.
Far from it.
First they have to use pumps, which employ some form of energy to pump the water UP to some kind of lake or similar.
Then let it flow downhill again, running through the turbine.
Then do it all again the next day.
I should not be too critical, they have no real knowledge of the true facts behind these fanciful statements.
And so they try to sound like they know what they are talking about.
Led and tutored by the greens, who know even less.

Luciferase,
There seems to be just one or two actually trying to work
out how to establish a 100% renewables and how much backup is needed.
The problem seems to be to define how physically large the grid
network has to be to take advantage of the difference in weather in
different parts of the network.
For instance the wind is blowing quite hard in Sth Aus today so SA
is exporting electricity.
A large country like Australia might just be able to do that but the
catch, (isn't there always a catch22) it means that a multiple of the
maximum grid demand has to be installed very carefully in different
parts of the network. A very high capacity grid is needed because
any part has to support any other part.

Anyone with the skills in modeling could make their name on working
that out.
The closest I have seen is the UK study that worked out the number
of batteries the size of SA's battery. 14,000 ! That would bend
any treasurers balance.
