The same tired old arguments Don, Did you whinge and moan when the railways took over from Cobb&Co, or the Elon Musk of his time Henry Ford started mass production of the horseless carriage, and putting all those farriers, wheelwrights and all the coopers out of work. I think that's the same old tired response I gave you several years ago. You really are stuck in some long distant past, and the world is moving on.
Wobert, really I don't mean to pop people's balloons but I do it all the time for some reason.
Electric will be a large segment but we also have to realise that planet has limited ability to supply lots of those rare(r) minerals that by necessity have to go into things like mobile phones, computers and electric cars et al. It will hit its limits at some stage and they won't be able to accomplish the noble goal of zero-everything.
No free lunches; hydrocarbons are going to prove irreplaceable in some tasks, that's just what will happen. Either we admit that we have to keep burning coal to maintain the luxury of consumer-driven electricity OR we go nuclear. One of the two.
My own state could have an advantage over the eastern seaboard by being close to the uranium industry already. SA could have a big plant and/or reprocessing/storage industry and send G/W down our existing and being built HV lines to the eastern seaboard - we could keep Alcoa and Whyalla going no problem with on-demand electricty whenever they want it AND we could probably even give free electricity to large employers. We have to get something happening in this state to get industry back here, we have the worst unemployment in Australia, not a competition we want to keep winning.
We have a "Liberal" Premier in this state, why won't he admit we're in an energy crisis in this state and announce a response to the Labor Party's (albeit unachievable) hydrogen storage and generation plant? If we really, really wanted to chop our average 75-80% coal dependency then the only way we could conceivably do that is with some large scale nuclear... maybe off the shelf from the United States (Westinghouse) molten salt type of things.
