Nucor’s $250 million micromill in Sedalia, Missouri, is set to be the first U.S. steel plant to run on wind energy.

A recycled steel plant run by EVRAZ in Colorado is transitioning from coal to solar in a partnership with Xcel Energy and a solar developer half owned by BP.

Although recycled steel plants run by renewables can make a dent in the industry’s carbon footprint, steel contributes as much as 6% to 7% of total greenhouse gas emissions.
