This insane. @abcnews runs a story about all the endangered wildlife from a UNDERGROUND coal mine extension.

Just 17 hectares of land will be cleared.

Ahem...

JUST 17 HECTARES!!!

The poor bats and koalas!!!
1/ Image
Of course 17 hectares is NOTHING compared to what's required for wind farms.

The 'direct impacts' to the bats is from 630 hectares of land that will WON'T BE CLEARED, but may gradually subside, over years. 2/ Image
Image
I looked up the subsidence reports. The area under the mines may drop a meter. If a 630 hectare area gradually subsides a meter, maybe a meter and a half over the course of many years, I'm pretty sure most of the bats and koalas will be fine. 3/ Image

Here's the NSW government deciding it's ok to clear 190 hectares of native vegetation for a wind farm.
More than 10X that for the coal extension... Explicitly including:
-large patches of remnant native vegetation
-an endangered ecological community. 4/ Image
This is for the Hills of Gold Wind Farm. Along with the 190 hectares of cleared land, the 62 turbines will emplace about 125 vertical hectares of lethal hazard for birds and bats along these ridgelines, including adjacent pristine nature reserves. 5/ Image
Here's some of the habitats impacted. Including some endangered or critically endangered.
At least 14 threatened fauna species.
45 hectares of koala habitat.
Oh, and 17 hectares for the Large-eared Pied Bat. 6/

How does ABC cover Hills of Gold? A bunch of bickering jealous farmers standing in the way of development. "Wind Wars" they called this episode of Four Corners. Not a mention of the Large-eared Pied bat, or any other species in this segment. 7/ Image
Image
Image
An UNDERGROUND coal mine doesn't have to clear the habitat of the Large-eared Pied bat. But ABC considered the risk of rockfalls from the land slowly subsiding justifies some heart-throbbing feature pictures of this species. 8/ Image
And yet the ABC doesn't blink for hundreds of vertical hectares of turbines spinning at one third the speed of sound, and think about what impact the collision hazard, noise, infrasound, as well as land cleared has for these creatures. 9/

Anyway, I've never felt more pissed off with the national broadcaster. The bias is insane.

@abcnews can we please get some more even-handed coverage of the ecological impact of energy infrastructure?

Yesterday this news broke: transmission costs rising, and pushing up power bills.

For those watching closely, this is no news at all, but belated confirmation from official sources of the inevitable. Quick 🧵on the @AEMO_Energy source. 1/

Two years ago prices were increasing massively. (left chart)
"Unprecedented" we were told.
This year they're increasing even more. But this time (right chart) the costs are almost entirely real, rather than half made up of inflation. 2/ Image
Image
The exec summary states why. The current plan requires an EEAAO build. Everything-Everywhere-All-At-Once.
(I think I'll pronounce EEAAO "Ee-Aw". )
Of course that pushes costs up. Competition for everything... labour, materials, contractors, etc etc. 3/

A senior executive at @the_AEMC has just given a speech confirming that doublethink is an essential component of the energy transition.

We all knew this was going to get Orwellian sooner or later! 🫠
1/ Image
Victoria is the Executive General Manager, Economics and System Security, for the Australian Energy Market Commission, or AEMC.

That's the organisation that makes the rules for the electricity system.

The full speech was yesterday; read it here. 2/

It wasn't a flippant remark. She devotes a full slide to explaining it with this incredible coffee analogy.

A quarter cup of coffee is simultaneously not enough coffee to drink, and far too much if you spill it on yourself.

Cognitive dissonance?? Oh my... 🤦‍♂️

Imagine if Spain's electricity transmission operator published a graph like this a couple years back.

This was actually from the NSW transmission operator, Transgrid, published in 2023.

1/ Image
Transgrid spells all the stuff that a few renewabros are still bickering about following the Iberian collapse.

Yes, renewables "need strong source of system security to operate stably".

I wonder if Spain had a document like this. 2/ Image

They were sizing up the need for a couple billion worth of synchronous condensers a couple years ago. 3/ Image

Spanish blackout 🧵.
Conclusion: relying on wind and solar, ie 'inverter based resources' creates a fragile system, lacking the inertia/system strength that synchronous machines (turbines, from coal, gas or nuclear) provide to ride through faults. 1/
yes, it's comical that just a week or so ago they were boasting about milestones reached being 100% renewable powered. Without very carefully addressing the system security implications of attempting that, it's a precarious position to be in. 2/

Enough of Spain.... what I really want to address is Australia's efforts to ensure we don't end up in the same mess. What careful system security measures are we putting in place to make the precarious position more secure?
The Aus reported maybe not enough. 4/

Yesterday I addressed the substance of this absurd piece of propaganda.

Someone is arguing that wind are better for electricity-intensive industry than dispatchable power such as nuclear or coal.

Now I'm going to explore who made that argument.

First, an important foreword. I really dislike identity politics. I'm determined always to address the substance of arguments irrespective of who makes them. Dismissing an argument because you don't like the connections or identities of people making them is a really bad and cowardly thing to do. The antithesis of good debate.

So I just want to say that up-front. None of this is meant to be any judgement of the types of people involved, or a suggestion that they shouldn't participate in the debate. Anyone of any age, gender, sexual orientation, religious conviction, union affiliation, educational background, professional experience can and should do whatever they can to participate in political debate. And I'll be the first to listen to their arguments, and assess them on their merit.

But when the arguments have no merit, and sources are falsely represented as meaning things they don't, long after the true meaning has been pointed out, it's necessary to ask how such arguments are given voice.

And to summarise my conclusion diving down this wormhole, these aren't the captains of industry engineering boffins one would expect to make a "this industry requires this type of electricity" type of argument. Hang tight.
The name on the paper is this Renew Australia for All.

"A new movement backed by social services, unions, faith, community and multicultural groups, environment organisations and industry" 2/

Here's their affiliations. All the usual suspects. Smart Energy Council, Surise Project, Clean Energy Council, Climate Action Network Australia, ACF, and....

"Tomorrow Movement".
What's that? 3/ Image

Buckle up... I think this is the worst energy disinformation of the election campaign.

We have a group arguing that transitioning to nuclear is going to eliminate electricity-intensive industry. Only wind, solar, and batteries can save aluminium. 1/

Who produced this? I hate identity politics and will always assess the quality of arguments first, regardless of who's making them. But these arguments are so, so bad, I'll return. Let's just say it's not the captains of industry or engineering boffins one would expect. 2/ Image
The entirety of the thesis hangs on the modelled drop in Large Industrial Demand in the Progressive Change, in the Integrated System Plan produced by @AEMO_Energy. 3/ Image
