Scrap smelting should use less fuel

...or ore smelting should be more energy-intensive.
In US, average energy consumption for producing a ton of liquid steel is 24.5 GJ, when using blast furnace and basic oxygen furnace. However, steel scrap recycling by electric arc furnace only uses 2.25 GJ per ton, less then 1/10 of BF+BOF's consumption.
Reducing ore to its elemental form is a really energy-intensive process, so it should be represented in a realistic game. It might disturb scrap-to-ore transition to some new players, but I think it's not a big deal.
To be compatible with Arc Furnace II, Direct reduced iron(DRI) and copper should be a thing. Ore
is reduced in DRI plant using coal, fuel gas or hydrogen to be melted on arc furnace II. This process could greatly enhance reality without any major recipe change.
