Every few weeks, John Ord does something unusual for most people living in 2019 — he stops by a local hardware store in rural northeastern Pennsylvania to buy coal to heat his home.
Ord’s coal-burning stove burns 24 hours a day when it’s cold. He likes the constant heat it gives off and says it’s cheaper than his other options — oil and electric.
There are apparently a few people here and there who still use it. I remember reading some article about a guy in the US who preferred it.
