ELECTRICITY !
Coal provides “fuel security” — the assurance that fuel is always available to use. “Baseload resources provide power generation whenever you need it,” says Grooms. “That’s one attribute of a coal plant that we count on, not just for ourselves, but for the grid. So fuel security is about supplying energy to the grid when it needs it, and coal is a very stable, low-cost fuel that’s stored on-site.”
Where does electricity come from?
(rhetorical question)
And steel.
