Also appears to disagree on the electric arc furnace. 300 kWH is apparently close to the theoretical minima for steel melting and arc furnaces are somewhere around 440 kWH. Which frankly, being that close to the minima seems fairly impressive on the scale of industrial steel melting. The general note about blast furnaces using more energy in the form of coal and gas is probably still relevant.
