The Committee on Smoke Abatement did a careful count of coal consumption in 1912. Twenty-one million tons of coal were consumed, or about 10 tons per person, six times the 1854 usage. About 3 million tons were used for trains, 4 million for steel mills, and less than 1 million to produce gas. The remaining 13 million tons were used to produce heat, electricity, and stationary power.
Stationary power included such things as the massive pumps used to provide Chicago’s water supply and 19th-century factories with leather belts from a central steam engine to individual machines.

Coal was also the dominant home heating fuel in Chicago. The 1940 Census shows that there were 949,744 occupied housing units. Of these 625,310 had coal central heating, 182,509 used coal stoves, about 100,000 used fuel oil, and 40,000 used gas heat, along with a few thousand using other fuels. Thus about 85 percent of the households used coal.

A Chicago Housing Survey shows that in 1970, 198,000 or 17 percent of the households used coal. Five years later, only 15,000 or 1.5% still used coal. Natural gas now heated 80 percent of all households.
Many buildings burned garbage with coal to produce heat and hot water. Coal heating was not an automatic process. Large buildings needed employees to move coal and ash, and run the boilers. Residential buildings of even a modest size employed members of the Flat Janitor’s Union to collect garbage. In the 1980s many of these jobs were eliminated. The Municipal Reference Library received calls from angry tenants who now had to haul their own garbage down the stairs.
Although a portion of Chicago’s electricity is still produced from coal, the last two coal-fired electric plants in the city were shut down in 2012. Coal is still used to make steel in Northwest Indiana. Inside the city, the only users seem to be a few coal-fired pizza restaurants.
Like most large cities, Chicago has a history of poor air quality. As it industrialized, Chicago relied on the dirty soft coal of southern Illinois for power and heat. Burned in boiler rooms, locomotives, steel mills, and domestic furnaces, the ubiquitous coal created an equally ubiquitous smoke. Soot soiled everything in the city, ruining furniture, merchandise, and building facades.
