With increasing size of solar and wind generation we could also think about adjusting our power consumption.
Luckily aircondtioners alrady are in demand when sun output peaks. No need adjustment here.
In China some biggest solar plants are utilized only at 15 % capacity.Since we don't have always capability to storage this access energy , we could try to convert this cheap electric power into something useful. For example production of aluminium require enormous amount of electric energy.
So any access of available electric energy could be directed into manufacturing, processing something usefull like aluminium.Then this pure aluminium could be used as currency . This conversion brings more benefit then 5-10c per kw hour. To produce 1 kg of aluminium require 13kWh and 1 kg of aluminum is worth $2
^^^ Yep, that's why these type of plants generally have their own power stations in addition to a very secure and reliable grid supply.

It's interesting to see that perhaps the government is still protecting coal in any form that it can.
Yep, in Australia right now, coal/gas fired power is the only reliable bulk electricity supply that can drive these loads. But hopefully sometime soon there will be an alternative.
MM, the real deal happens in Gladstone where it gets refined into alumina at QAL and then turned into aluminium at BSL. And that's why they built a big @rse power station specifically to power these enterprises with the whole deal being underpinned by supply contracts/allocations from the big consumers in town. I'm not sure about BSL, but certainly QAL used to have their own power station on site to keep the process going if their grid supply was interrupted.
But you've hit on one of the big issues, and it is that we locate industry as near as possible to an energy source (in an area we sacrifice to basically become an industrial wasteland) and if we relocate the energy source then the industry is less efficient/secure and may need to be relocated to the new energy source.
For our current big industry demands, the current technology alternative energy probably just isn't viable here yet, but for the rest of us it makes a lot of sense. However Harrow and Bara have opened my eyes to the impact on the price of coal fired generation caused by less demand for coal fired generation.
Well we used to have steel mills, but we mustn't have been able to compete or we'd still have them. It was probably another "protected" industry that was subsidised into not being competitive just like the car industry. I think there's a bloke having a serious crack at restarting the steel mill in SA.
Isn't there a Euro mob having a crack at building home power batteries in the Holden Elizabeth plant? Or did I recall that story incorrectly?
What if the technological jumps necessary to render renewable baseload generation economic never eventuate? Then we find out we've wasted twenty years and countless trillions of dollars when the nuclear solution was available form the time the problem became apparent.
At what point will the mainstream green lobby admit that renewables will probably never be able to replace fossil fuels for baseload generation? It better be soon or we could all be f*cked.
Bwahaha, that's the "countless trillions of dollars question"
I wonder if anyone has worked out an actual date, where an alternative/clean bulk power supply must be found before that date; in order to make the whole of life cost of kicking off a nuclear power plant right now become unviable.
There's always the pump storage option. It's just a matter of whether batteries, hydrogen, or some other alternative displace it.
Yes, but why would those things displace hydro? It's about the energy mix being right isn't it?
They all work at different times, sometimes all at the same time! Happy days.
Solar and wind can be used to pump water upstream.
Hyrdo can be used when the sun's not shining and the wind's not blowing.
Hydrogen can be made using solar PV and wind and hydro...etc
Hydrogen turbines do the lot and emit water vapour!
All works with the grid.
Economy is about scale, integration and delivery to market. Perhaps hydrogen will be the battery of the future, without all the nasty chemicals that go into solid state batteries.
I agree, pumped and hydrogen are the only things that are truly totally sustainable. Unless they can 100% recycle used batteries, they can't be the permanent solution for millennia.
