here’s a better photo of #callide unit 4... the QLD “HELE” coal generator that shat itself last week, reportedly embedding a 300kg piece of shrapnel in the roof.
🤓 heard the one that there are few ongoing jobs in renewables?
turns out it's nonsense.
@UTSISF's detailed 2020 report, based on AEMO projections, shows the renewables sector provides a good and growing number of good, secure & regional jobs… 🧵
RE sector has 2 arms — construction and operations.
construction jobs will continue for decades. currently construction outnumbers operations, but as fleet grows operations becomes the majority.
i added the red line, coal power jobs.
RE already employs more than coal power.
(this chart does not include jobs in building new 'poles and wires', bioenergy, professional services, renewable hydrogen, mining inputs for RE [e.g. nickel, lithium, cobalt, rare earths] or industrial expansion arising from comparative advantage in energy-intensive industries.)
while there's an immense amount of energy in all matter — E=mc² and all that — we *don't* have technology to get a lifetime's energy for a person out of a golfball sized lump of uranium.
if you did want to power an average australian's lifetime energy needs from uranium, what would it take? 🧐
…by a couple of different methods (link at end), i estimate that 2.1GWh would cover all the energy needs of an average australian lifetime, assuming full electrification.
working back from this handy chart from @WorldNuclear, in the best case you'd need 417cc of nuclear fuel (mainly UO₂) for a single australian's lifetime.
