Due to war, politics and economic profiteering by governments. When the world needs a tenfold increase, it's getting less.
This global shortfall is the primary reason for a push for countries like Australia and the USA to further open up resource mining, which is ironically being opposed by many of the same groups that push renewables. The take a NIBMY position, wanting SolarPV and Wind, but only if the materials mining is NIMBY.
Some may even argue, the best way for tiny little trivially polluting Australia to assist global carbon reduction targets in to not need or restrict any of the critical resources itself.
You keep making these claims but there's zero evidence to back them up. Do you really think that AGL, Origin, etc don't have a handle on the global supply chain?
The owners of the coal-fired power stations are shutting them down under shareholder pressure. That's mainly because they're becoming uneconomical, gas-fired power generation is a cheaper and better medium term alternative and renewables are by far the cheapest long term solution for Australia.

When the targets aren't reached a decade or two from now, it won't be those companies or executives in the firing line, it'll be blamed on politicians, and in any case when the fixes are needed the executives who raised the funds will be long gone bonuses in hand living a quiet comfortable Alan Joyce style retirement!
They can make whatever claims they like, the claims will make bugger all difference 10 or 20 years from now!
btw., I hope you are not denying there is a supply chain issue, there are a lot of workers currently being made redundant simply because installers cannot get SolarPV panels or Wind turbines. Australia is a long long way down the pecking order for most international suppliers.

On the waste issue, particle or photon radiation diminishes by the inverse square law. Most medium and high level waste is stored under water, just one metre of water cover cuts radiation emission by 1/2, two metres of water cover and the neutron and gamma radiation is halved again so down to 1/4.
Most cooling and storage facilities put a purified water cap over waste of between 6 to 8 metres in depth. So the radiation level falls to 1/36th or 1/64th. And no the water doesn't become radioactive at all, it's not nuclear homeopathy! The facilities are so safe people work without special clothing, have done so for decades, free of specific health issues, all they have to wear is a safety related dosimeter just in case they get exposed to something without the water cover. When you see the media coverage of people is special suits staring into a pit of Cherenkov glowing waste, the suit is done for TV not for any real protective reason, in fact the suit would be no protection at all compared to the water that is already there. Actually, standing above the storage / cooling facility pond you get less ambient radiation exposure than you would typically get standing outside on ground. The dirt under your feet is full of lightly radioactive particles and other stuff like radium gas which leaches out of the ground basically everywhere on earth.
Ironic, the place that activists want you to believe is deadly and contaminated is quite possibly delivering lower radiation doses than the local footy field! Humans are terrible as assessing risk, they are slaves to emotions and rumours. A person that is petrified of spiders, will tell you how they dread the thought of them while sucking on a smoke!

If only we could elect some scientists to high ranking political positions, a lot of our problems would magically go away.
If only we had an Elon Musk to simply build something without having to go through all this red tape, a lot of our problems would magically go away.
But no.
We elect politicians who are just about lining their own pockets and listening to their own voice, and looking at their own reflections and nothing ever happens.

Look at AEMO announcement today, just to replace the coal on the announced schedule, we basically need fivefold or tenfold increases in every alternative over the next 10 to 20 years, including gas, hydro, solar, wind, battery, (Actually battery they state a 20x more investment is required.)
Then they go on to claim it's still $120B of investment needed, what a joke, they are surely taking the piss because the public won't do the basic math. The $120B might be the starting figure, but it's going to be many times that, maybe $360B will get the job done, $120B will just be the deposit.

Augmentation means to add to what we have....thats not what the Gencost document suggests in terms of transmission line planning, it was upgrading the old/new 220kv lines rated for higher temperatures to carry more load and a seperate 500kv System connecting to the NSW system....those towers are higher than what we have now and the easements larger....who is paying for all that?
Re: The Climate, Environment and Energy Thread - LP - 06-26-2024
The Committed part is rubbery, it's the Chairperson, CEO, CFO and politicians publicly claiming, "We'll build $10B of renewable over the next decade" all hot air to attract investments from the Insurance and Superannuation funds that can put "Going Green" on the brochures!

Some interesting new research suggests the climate carbon cycle models aren't quite right.
It appears plants take in more carbon than previously understood by existing models, as much as 30% more, but they also release more of that carbon than expected, the mechanism is not yet clear. It doesn't change much, as the increased uptake is almost balanced by the increased release, but it probably means there will be significant revisions to many climate models, as there are extra steps in the cycle affecting rates of change and duration.
It also suggests some of the modern R&D into GM crops could turn out to be a very valuable avenue to meeting net zero carbon, and yield increases in grass and grain crops are basically a direct measure of the percentage of carbon being converted. On average apparently as little as only 2% of carbon taken is converted to seed or biomass. If you can increase the size or quantity of seeds or fruits you are directly increasing the amount of carbon capture / conversion, if you go from 2% to 3% that's a 50% increase. Some countries living at the tough end of existence are already onto this, but it seems the self-righteous Europe / Western nations are still anti-GM at any cost. The numbers are staggering, very small changes can equate to billions of tonnes.
On a downer, there is also a study that discusses the over-farming of the oceans, which is causing the oceans to diminish as a carbon sink, we are removing too many fish and as a result the carbon isn't being absorbed for permanent or intermittent sequestration.
Such is humanity, give with one hand, take with the other! :o
