His argument is that we need to mine more material for "renewables", correct?
>Mining for these raw materials would have to increase by >300%
A ton of coal produces 6 MWh, for 1 TWh that's 166,666 tons
Total mined tons for Solar PV, per his chart: 16,000
Total mined tons for coal power, plus the coal: 167,666 tons
That's ten times more.
