coal
Black combustible rock
Coal is a black or brownish-black solid fuel formed from ancient plant matter compressed over millions of years.
It burns to produce heat and has powered industrial economies since the 1800s.
To rake someone over the coals is to criticize them harshly.
Coals to Newcastle describes something pointlessly redundant—Newcastle was England's coal-mining center.
