Well now..........etc etc
You are mostly referring to practices of old and generally small scale operations. It wasn't until the early to late 90's depending on your state that the days of "mine at all costs" was no longer supported by the Voting public and things began to change. I was in Tassie at the time and worked in the Heavy industry and later mining sector and I believe the ministerial exceptions to pollute and mining clean up all ceased around 1994.
Miners pay a Remediation bond, its not a guarantee and would destroy the mining sector if it was. The value of the bond varies over the life of the mine based on the work done by the miner to minimise the clear up costs at the end. Meanwhile the bond is held by the govt and invested and hence for the life of the mine the govt basically has dividends from that investment. The mine I worked at in Qld had its bond reduced after undertaking significant mid life remediation. Again the mine started before most of this was required. Operating without sufficient funds to undertake remediation is also likely operating while insolvent and I assume carries all the penalties for the directors that usually apply. Overall the bulk of the mining is undertaken by large scale multi-nationals who now are more focused than in the past. Again its not what they do, its WHAT WE VOTE TO ALLOW THEM TO DO. ie community expectations.RE
How many times do you need to be told about the reality?
- Northern Power shutdown and SA wholesale power prices nearly doubled since. Impact on National Market not significant, due to limited impact out side SA
- Hazellwood shutdown and Vic wholesale power prices doubled since, along with NSW and Qld due to the National Markethttps://www.aemo.com.au/Electricity/National-Electricity-Market-NEM/Data-dashboard#average-price-table
Transition is fine, but it must be a transition, not abandonment without a Plan B. Unlike much of our northern hemisphere cousins and NZ, Aust lacks large scale hydro capacity outside Tas and Snowy. The inter-tie to Tassie is of limited size and basically half that of one coal fired turbine, so its impact on the mainland grid like SA is limited and the so called justification for its cost by buying cheap power and selling peak power is marginal at best and why a 2nd cable will be hard to justify although technically required.
In short Australia was forced down this ideological path with its eyes shut and ignored the technical limitations of RE as it applied to Australia.
Until 2008, the feds had very little to do with electricity as it was mostly run by the states. Then it started with the push towards a National Grid and market (in itself not a bad thing) and then later CO2 tax. Had the feds stayed out of the sector, things maybe very different today. Yes Abbott stopped the madness push into RE, but he didn't provide the alternative and very much part of the problem, but not the source of the problem and likely didn't have time to fully correct and MT didn't do much better in his time. But again why where we were there in the first place? Had the states continued with their plans to build replacement coal fired power stations, we wouldn't have aging coal fired power stations and half arsed RE replacements including high cost open cycle gas turbines being the back bone of the East Cost Power supply.
Remember Qld has not shut down coal power stations, rather they are now running at much higher capacity than ever before and the state is raking in billions a year in profits from selling power to the power deficit states who have blindsided their voters that they are shutting down their coal power sector, yah!!! Thanks to the much larger inter tie to NSW built in the 2000's, Qld govt is now ripping off its own voters and industry with double the price wholesale power costs, thanks to the idiots in the south. Meanwhile the state Premier craps on about how they plan to push for RE and Green credentials, bank rolling on the profits from the coal fired power sector and selling coal to the Chinese and Indians.Gas,
Again, this wasn't a fed issue before, the states made it one, namely Qld allowing its CSM gas producers to sell gas it didn't have and in the process rape the east coast gas network and customers of affordable gas.
As you made this political, I'll state now that Qld has had ALP govts since 1998 apart from 3 years under Newman.Roof Top PV
I totally support the concept, but when this all kicked off in the late 2000's, whole sale power prices were $30-50/MWh, yet most of the state govt subsidised this by buying power at $400 to 600/MWh. Ok, it was a tool to kick start an industry and PV prices were much higher then. But why does it need to continue? As you say, PV solar prices have dropped dramatically? typically 10% YoY. Most of the cost is actually labour to install. Now we are repeating the madness with batteries?
Do I think PV solar with battery will be a key part of the future, yes. But why does it need to be subsidised now?Transition
The transition starts when there is an alternative, not before and doing with a subsidy is pure madness. You claim the mining sector is subsidised, its checkfeed compared to how much has gone into RE and again we still don't have a feasible solution to the 24/7 issue for which there is 17,000MW of generating capacity that needs to be replaced and when adding EV's to the picture, that pushes this to at least 34,000MW of generating capacity by 2045.
And as for 42" Plasma, in March 2002 I saw the first one marked down from $42,000 to $36,000 in Harvey Norman. In 2008 I paid $1800 and recently paid $900 for latest Samsung 55" TV. Your point that you paid $7000 sums up your whole post. You ventured into a new industry too soon and paid the price, some of waited a bit longer and got better performance at a lower price, in this case it was your wallet that was affected, but in the power sector, now its everyones wallet that is affected.
Yes, it took 50 years to go from the moon to Mars Rovers and likely another 20 to get humans. It wasn't done overnight and only done once the technology was feasible. The Power Generation Sector is no different. Replace The aging coal capacity (yes Hazellwood had to go) with new coal and then lets move towards a 100% RE grid at a practical pace, not the brain dead approach that is occurring now.Side comment
Was at a conference recently for Aluminium Production. Since 2005, aluminium production using hydro and nuclear power topped out. The growth is now all gas and mostly coal due to capacity growth in Middle East, India and China. In the aluminium sector alone, China has added 2-3 x the amount of coal power to feed the aluminium sector than the Australian power sector in total. Ironically some of this burning Australian coal. I hope seeing a few wind turbines makes people feel good, because the reality is an eye opener.
