I suppose it all comes down to what Neil considers to be "next generation of solar panels and wind turbines". If whatever is out 50 years from now is next gen, then that may be correct.
A few examples of electric heavy equipment and the stationary machinery that has been electric for a long time does not represent the bulk of the work done to mine, refine, and transport raw materials into finished goods. It all relies on fossil fuels even if parts of the process are electric, or diesel electric (which is diesel then).
