I saw this article linked by David Brooks of the New York Times.

There appears to be no paywall, and aside from some quibbles, I found it interesting and well researched.

    They totally forgot about Latent Heat, which gives steam its remarkable heat-moving capacity.

    Rochester NY (about 50 miles from Lockport where Holly was born) has a downtown fire protection loop throughout the center of the city called "The Holly Loop". It maintains 135-140 PSI working pressure. Still in use over 125 years now. I saw an original high pressure pump on display.

    I thought that ConEd used steam from back pressure turbines? Sometimes I try to design thermocompression steam heat. Condensate may make satisfactory make up water for cooling towers. I suspect those giant oil refineries use a form of district steam heat?
