  • I completely agree on the wind towers, but I find this but strange:

    The energy market operator says the surge in renewable energy generation expected by 2050 needs to be connected by more than 10,000km of new transmission lines and 25,000 transmission towers – each needing up to 60 tonnes of steel.

    Australia has plenty of local cable manufacturing capacity, between Nexans Olex, APEC, Physmian and Elcon. We also have plenty of bauxite and most states have an aluminium refinery and smelter.

    We also have plenty of capability to manufacture towers. But most Australian tower manufacturers are now fabricating them in pieces in Thailand/Phillipines and then assembling here, because boilermakers and coded welders are $60/hr in Australia but $6/hr in south east Asia.
