This is a wonderful benefit of living in a big city. E.g. Con Edison in New York supplies steam to commercial buildings.[1] Back when they generated electricity "locally" in each borough, the steam was almost free for them to generate as a side effect. But now they actually have to pipe steam under the East River.

But I no longer live in NYC. I don't miss the rats or cockroaches or traffic or air pollution. C'est la vie.
