well next federal election will tell in relation to Cessnock etc if they start shutting down coal mines etc then plenty of Labor and union workers will be struggling. It will be like when Howard received a standing ovation in Tasmania years ago prior to the election by the loggers.
Good luck to Labor
I doubt any Australian government would ever 'shut down' coal mines that are in operation. But they won't need to, mining companies are getting out of coal of their own free will. Rio Tinto doesn't mine coal anymore. BHP said it doesn't want to mine thermal (energy) coal anymore, and is actively trying to sell those assets (though it is having trouble finding buyer, which tells you all you need to know). Most of our big customers in Asia have signalled they want to shift to renewables and away from coal over the next few decades. This will take time of course, but it is a definite trend.
But if a shift to renewables is bad for coal mining, it is good for other mining. Western NSW in particular is set to benefit from mining for the renewables/battery industry, with several large nickel/cobalt/scandium mines (that would employ thousands of workers) in the offing around the Parkes-Condobolin area in particular, and further west around Cobar.
We still need to solve baseline on-demand power. Renewables and batteries just won’t cut it for the foreseeable future. Choice of Coal, Gas or Nuclear you pick.
The Australian Energy Market Operator thinks 94% renewables within 19 years is realistic.

" the central message is this: The energy transition is inevitable, it’s accelerating and there’s not much point in resisting it. “This system is now experiencing the biggest and fastest transformational change in the world,” it says.
Even a “do-nothing” business-as-usual scenario delivers a 74 per cent renewables share by 2040. A “step-change” could deliver 94.2 per cent renewables by 2040. So if Australia is smart, can take advantage of its natural advantage in wind and solar, can lock in its technical know-how, and deliver a system that is smarter, cleaner and cheaper than what it has now, then it can position the country to become a renewable energy and economic superpower.
“It is inevitable. It is just who we are and what we are,” AEMO boss Audrey Zibelman told RenewEconomy in an interview ahead of the release. “We are at a position where the existing coal fleet is coming to an end of its technical life and is going to retire.”
Zibelman says coal will be replaced by renewables because the cost of wind and solar technology have already plunged in recent years and will continue to fall, and together with battery storage and pumped hydro, and other forms of dispatchable generation, they clearly offer the cheapest and obvious replacement."
It’s not inevitable unless some innovations happen in storage technology. At the moment we are making very small incremental advances. We need a major leap in storage technology before 94% renewable is anywhere near achievable and the AEC know it.
I think it is happening pretty fast. It was only a couple of years ago the 'Big Battery' in South Australia was announced to great fanfare (or derision, depending on your perspective). Yet a few weeks ago a battery ten times its size was announced to barely any attention. Just in the space of a few weeks, new grid-scale batteries have been announced in NSW, Victoria, the ACT, the NT and South Australia. In isolation any one of these might not be that significant, but collectively they are very significant.
It’s not happening fast at all. That’s the issue. The big SA battery is a great thing but it is only band aid addition to stop SA having continuous blackouts. It’s not the main source of power at all.
It’s great that we use renewables but don’t think any time in the short to medium term they are going to replace Coal, Gas or Nuclear. One day maybe when we have a breakthrough in storage, but unless that happens it’s a long way, decades, off.
21% of the grid is renewable, target of 23.5% this year is anticipated to be met also.
That’s great. It’s good because we come from such a low base but it is not going to replace Coal or Gas for decades (I accept we are not going Nuclear), certainly not in my life time. If I had my way I would mandate solar panels on every building in Australia. However even that would not cover baseline 24x7 let alone peak usage.
I couldn't disagree more, I think regardless of government we will be well over 50% by 2030, and at close to 100% renewable by 2040. Anyway we'll find out either way soon enough.
The International Energy Agency says renewables will be the largest source of electricity production globally within 4 years.
Renewables + storage are winning on economics alone.
