US Steel Production Required For Energy Transition

Let’s do another simple calculation of what it would take to set up an alternative energy base. From Wikipedia we learn that the US produced 88.6 million ton of steel in 2012. We saw earlier that a 5 MW windturbine needs 700 ton of steel in total, price ca. $700/ton. Three days ago we blogged that in order to replace 40% of the US current electricity production by wind, as well as power an EV for every car currently driving on US roads, it would require some 250,000 3 MW wind turbines. Or 150,000 5 MW wind turbines. The rest of the electricity could be generated by 40% solar and 20% hydro. These 150,000 turbines would require 105 million ton of steel, or a little more than one year US steel production. If we assume ASPO to be correct in stating that between now and 2040 global oil production will be reduced by 50%, than it is not difficult to conclude that a transition avoiding collapse is not a priori impossible.
