The North American steel industry has continually reduced its need for energy, thus minimizing our footprint on the environment. Since 1990, energy intensities to make one ton of steel have been reduced by 28 percent.
Because of these advances, the steelmaking processes we use today are approaching the limits defined by the laws of physics. To make further reductions in energy use and CO2 emissions, new processes are required. The CO2 Breakthrough Program is an international research project striving to meet this challenge.
Steel is also a big part of creating a green energy infrastructure. To learn more about steel and renewable energy, read this WorldSteel case history on Wind Energy.
