Yes, it takes quite a bit of energy to make steel. To make one kilogram of steel from iron it takes 20-50MJ (5,550 to 13,900 watt-hours) of energy.
To make this same amount of steel from recycled steel it would only take 6-15MJ (1,665 to 4,170 watt-hours) of energy.By recycling we would save 2500 pounds of iron ore and 1,000 pounds of coal, not to mention we would be reducing our carbon footprint significantly.
For comparison, the average household uses 1500Kw hours per month.
