Energy use for steel sector, 2010–2050

Tags


Projected reductions in steel demand will reduce the energy required by the industrial sector by 111 trillion BTU/y in 2050.

The U.S. Energy Information Administration predicts steel production in the U.S. will decline after 2020. RMI extrapolates this trend to 2050, but modestly accelerates it to model the effect of switching automaking from steel to advanced-composite structures. Conservatively, we don’t assume that the resulting lower cost of carbon fiber to nonautomotive manufacturing will cause further substitutions displacing more steel.
