Yesterday’s excerpt from Energy & Climate Wars showed why increasing energy consumption in poor nations is essential for any quality of life improvements. In today’s post from Clearing the Air: The Real Story of the War on Air Pollution, Indur Goklany argues that the United States’ economic gains improved not only their wealth, but also their environment, and primarily without government intervention.

Clearing the Air was published in 1999
The real engines for progress on the urban smoke problem in the United States as well as in England were economics and technological change—forces that began in the late 19thcentury and have continued, for one reason or another, to the present day. New, cleaner energy sources such as natural gas, oil, and electricity became increasingly available as substitutes for coal and wood in homes, businesses, and industries. Urbanization, while responsible for many environmental woes, accelerated the process of substitution because higher population densities reduced access to wood and increased cost-effectiveness and economics of distribution systems for natural gas and electricity.
New technologies entered the marketplace that increased the efficiency of all types of combustion equipment, reducing the amount of soot produced and fuel burned for a given amount of usable energy. Those technologies included more efficient and cleaner furnaces and boilers for homes, businesses, industries, and power plants. In some places, underground and street railroads powered by steam were electrified; in others, electrification replaced horse-powered street cars, reducing another, but no less real, form of pollution. The automobile, which would later be viewed as an environmental villain, was still a relatively little-used luxury; in 1910 there were two automobile registrations for every 100 households. In fact, the use of motor vehicles in urban areas served as environmental purpose by reducing the horse population and associated wastes, as did the electrification of street railways.
The realization that smoke signified unburnt fuel led industry, railroads, and even households to make efforts to reduce it. It was thought to be not only good economics but also good citizenship. That notion was clearly incorporated in the Ohio statute, which allowed municipal authorities to “compel the consumption of smoke.” In time, even the Great War would be pressed into service against this foe; as the Pittsburgh Bureau of Smoke Regulation exhorted, “it must never be forgotten that loss of black smoke means loss of heat and that every unit of heat thrown away is so much aid given to the enemy.” On the other hand, the Bureau of Mines, part of the U.S. Department of Interior, suspended its smoke abatement “campaign” during the war years. At the other extreme in Milwaukee, the war was used as justification to go, literally, full steam ahead; as a result, “smoky” days increased from 47 in 1916 to 212 in 1918.
