ELI5: Why do places like New York City use a steam network to heat buildings where in other parts of the world use boilers and pipes?

It is efficient to use the heat from a power plant to heat buildings. First the the steam is used to spin the turbines for electricity production. The steam is still hot but to  extract more heat from the steam  the turbine blades would have to be enormous. The pressure is below atmospheric pressure. To condense the steam cooling towers are used. Or the heat can be routed to warm buildings. The building have to be close.

The engineers have figured this all out. They are really smart and use a lot of math.
