My wife and I attended the Newcastle Earthquake as rescue personnel in 1989. And just west of Sydney is the Kurajong Fault. That will slip sometime. We do have significant quakes in Aust. In the next 1000 years we WILL have serious earthquakes where people will die and buildings collapse.

It's just not going to happen.

Renewables aren’t as cheap as what you think when you start getting anywhere near a critical mass of it together - it becomes problematic and expensive to overcome these hurdles - I posted a video about this in Alternate Energies - you should go check that out.

Until the statewide power grid was organised most Qld. country towns had a small power generating plant. Fine if you lived in town. Not good if you lived outside on a farm or grazing property. The stations were typically a slow speed oil engine with an "engineer" who ran it and maintained it. Longreach had a gas engine and they railed coal in to produce gas for the power station. One small town had a private syndicate who owned the power station. To get electricity you had to join the syndicate by buying shares in it. It was rumoured that certain persons were refused shares because they were the wrong old school, religion, or lodge. I don't think our farmers and graziers would want a return to this system. Most in the west only got an electricity mains supply with the fairly recent Homestead Power Initiative using the single wire system.

Edit:- Typically these local power stations often did not provide a 24 hour service (like the manual telephone exchanges) closing for maintenance or overnight due to low demand. Think on this. If the oil engine stuck a leg out of bed the nearest spare parts were often in Manchester or Buffalo. Sorry folks. No power for 6 months.

couple of reasons.

the mines arent always hydrostatically stable and the water pressing down can have interesting effects on seepage, local soil stability and the water table.

mines generally have one big pit which if you fill with water to make a pumped water storage system you then need to make another reservior to pump to or from.

before you think of askingAhh but what if we damn it half way along?

you run out of head height very quickly

Yes please but for base load only. Renewables can do the rest. We are gong to have to charge all those EV's at night when the sun sleeps & when the wind doesn't blow.

I worked on the control system on a plant which is re-packaging nuclear waste & learned that when correctly packaged, the waste is manageable & stored above ground.

Simply yes or no.

Plenty of old underground coal mines around Bundamba to store the waste in and stop the back yards falling in.[bigwhistle]

GEE, Gritty East Express.[biggrin]

solar and wind have massive government subsidies they are very expensive to put up and remove then there is the cost of breaking theses units into there individual parts the life span of a solar farm is about 25 years and over that time the power produced becomes less as the panels age. We all want cheap power for our family and industry the thing is what price are we prepared to pay for this.
