91% of Australia's energy comes from fossil fuels. There is nothing wrong in trying to develop alternatives, but acknowledge that it will take many decades to substantially replace fossil fuels. Whatever reason we have for doing it, it will make no difference to our climate, as we contribute only 1% to 1.5% of global emissions, even if you believe these affect climate. The greatest risk to our economy and way of life at present is the self destructive idea of net zero.
