Last year, the Department of Energy proposed using amorphous steel. But some electricity providers, power companies and steel plants objected.

Unions are more visible and vocal than they've been in decades. If the labor market remains tight, they'll have negotiating leverage.

The UAW fought for protection if factories shut down. But workers in other carbon-intensive industries could find themselves displaced.

Contracts with Ford, GM and Stellantis all end at the end of Thursday, and the president of the United Auto Workers union has made clear that members are prepared to strike.
