“How are these wonderful renewables are going to be made, once his coal mines and Coal fired generation plants are shut down.”
  
The answer is that the  energy will come from hydrogen generated from wind and solar electricity and excess electrical energy  stored in pumped hydro or fuel cells. Australia  has a unique opportunity through its vast solar and wind resources to become a major player or exporter in  the new hydrogen economy just as Ross Garnaut   says  in his 2008 report.  Coal  fired power stations have no long term future in  Australia which the market is already telling us!

YF-“How will you make steel and other products, without burning or mining coal?”
Answer-Using wind, or solar to generate hydrogen which can then be stored and used as required   for steel making or electricity for other purposes/products!

Yf claims that using hydrogen for steel making is not yet viable which may be true but it can and will be used in future steel making as the following show.
The growth of hydrogen within steel production demonstrates the viability of the technology outside of direct energy production. Incorporating hydrogen into industrial processes is necessary to wide scale decarbonization and worldwide emissions reduction. As hydrogen continues to become readily available, so will the opportunities to make industries green.

Another nail in coal’s coffin? German steel furnace runs on renewable hydrogen in world first
German manufacturing giant Thyssenkrupp has completed a successful, first-of-its-kind demonstration of running a steel furnace completely on hydrogen, a development that is likely to further dent the future prospects for the global coal industry.
The company successfully demonstrated the ability for hydrogen to be used to fuel a steel blast furnace, and Thyssenkrupp sees the achievement as the first step towards transitioning the manufacturing industry towards zero-emissions steel production.
The use of hydrogen to fuel the blast furnaces in steel production also provides a pathway for using renewable hydrogen, potentially eliminating the dependence of the industry on coal.

How Hydrogen Could Solve Steel’s Climate Test and Hobble Coal
Steel could shed its reputation as a climate threat by using hydrogen instead of fossil fuels for as much as half of global output by 2050, according to BloombergNEF.

In future more steel and other products will be recycled rather than produced from raw ore.
We can use H2 for steel making and to power our economy-it just requires the will, and the planning and we can use the H2  power to also recycle and reuse many more plastics and other  materials like glass etc.

How hydrogen could change the face of steel production as we know it
In order to reduce its emissions, the steel industry needs technical innovation. Sweden has one possible solution
  
  
  
YF: we can and we must reduce the use of coal in steel making by using  hydrogen!If we can develop the technology to detect gravitational waves then we can develop the technology to make steel  using much less coal by using H2 produced by renewable energy sources .

Power-to-Steel: Reducing CO2 through the Integration of Renewable Energy and Hydrogen into the German Steel Industry
Alexander Otto 1,2, Martin Robinius 1,2,*, Thomas Grube 1,2, Sebastian Schiebahn 1,2,
Aaron Praktiknjo 3,4 and Detlef Stolten 1,2,5
Abstract: This paper analyses some possible means by which renewable power could be integrated into the steel manufacturing process, with techniques such as blast furnace gas recirculation (BF-GR), furnaces that utilize carbon capture, a higher share of electrical arc furnaces (EAFs) and the use of direct reduced iron with hydrogen as reduction agent (H-DR). It is demonstrated that these processes could lead to less dependence on—and ultimately complete independence from—coal. This opens the possibility of providing the steel industry with power and heat by coupling to renewable power generation (sector coupling). In this context, it is shown using the example of Germany that with these technologies, reductions of 47–95% of CO2 emissions against 1990 levels and 27–95% of primary energy demand against 2008 can be achieved through the integration of 12–274 TWh of renewable electrical power into the steel industry. Thereby, a substantial contribution to reducing CO2 emissions and fuel demand could be made (although it would fall short of realizing the German government’s target of a 50% reduction in power consumption by 2050)

“This study demonstrates that it is possible to reduce CO2 emissions by up to 95% through the integration of renewable electrical power into the currently coal-based steel industry by using alternative technologies. Both the possibility to integrate renewable power and CO2 reduction is mainly achieved by an increase or complete discontinuation of coal or the resulting BF gas, which is usually burned for power and heat production in order to avoid release into the atmosphere"

 YF it is clear from my research that it is technically feasible to make low C steel without using coal .The other products you mention can be made from natural gas which although a fossil fuel  will produce less C02 when burned than coal.Many of these products can also be recycled which will and must become part of a low carbon future.It also clear that Australia can power its future economy without coal using renewable generated electricity and hydrogen.  In the long term coal has no future in Australia! The bottom line is this:  to avoid the potentially catastrophic global warming the world must reduce its emissions of C02 from all fossil fuels and this means means drastically reducing the consumption of coal, oil and natural gas.
Its possible to produce high quality steel without using either coal or hydrogen by a process called molten oxide electrolysis a  method developed at MIT and some other methods.

From YF
How do you intend to make the following products without coal?
Tyres, Carbon film resistors, Baking powder, plastics, synthetic clothing, Graphene, carbon fibre, carbon rods, paints, aluminium.
I could fill a decent sized book with all the products that are directly made from coal, or from it’s by products, and most of them require burning the stuff.


Answer
Its been shown that its possible to convert C02 into carbon (including graphene!) using  electrical energy energy and a special catalyst. This work has been done here in Australia. So if this can be up sized then there is no need for coal! Clap Hands
doug smile
Ps you can make baking powder by bubbling c02 through an alkaline solution :you do not need coal! You do not  need coal to make Aluminium( you could produce the C from atmospheric C02- don't you bother reading  YF!!!) . You also do not have to use carbon anodes in Al production other high temperature  metal alloys can be used as well as ceramics and doped cements.Alcoa  is scheduled to change from C anodes to these new materials in 2024!!
 In fact most of the things in your list can be obtained by recycling what we already have! Electricity from renewable sources is already far cheaper than that from any coal fired power station and the cost of  electricity from renewable sources will continue to fall. The market will dictate what  happens in future and i doubt very much  that it will support new coal fired power stations either now or certainly not in 100  years!Your post suggest to me that you have some association with the coal industry which is why you seem blind to  reality.
