Energy and Civilization: A History
Vaclav Smil
Top 10 Best Quotes
“Could such a shift be accomplished without eventually converting to a no-growth economy and reducing the current global population? For individuals, this would mean a no less revolutionary delinking of social status from material consumption.”
“But if today's low-income countries are to move from poverty to an incipient affluence... then none of those factors could make a difference without the rising consumption of fuels and electricity: a decoupling of economic growth and energy consumption during early stages of modern economic development would defy the laws of thermodynamics." (p. 350, italics added)”
“Despite many differences in agronomic practices and in cultivated crops, all traditional agricultures shared the same energetic foundation. They were powered by the photosynthetic conversion of solar radiation, producing food for people, feed for animals, recycled wastes for the replenishment of soil fertility, and fuels for smelting the metals needed to make simple farm tools. Consequently, traditional farming was, in principle, fully renewable.”
“When ranked by the size of their labor force, in 1960 11 out of America’s 15 largest companies (led by GM, Ford, GE, and United States Steel) were producers of goods employing more than 2.1 million workers; by 2010 just two makers of goods, HP and GE, employing about 600,000 people, were among the top 15, and the group is now dominated by retailers and service-providing firms (Walmart, UPS, McDonald’s, Yum, Target).”
“Battle death rates—expressed as fatalities per 1,000 men of armed forces fielded at the beginning of a conflict—were below 200 during the first two modern wars involving major powers (the Crimean War of 1853–1856 and the Franco-Prussian War of 1870–1871); they surpassed 1,500 during World War I and 2,000 during World War II, and were above 4,000 for Russia (Singer and Small 1972). Germany lost about 27,000 combatants per million people during World War I but more than 44,000 during World War II.”
“electronics and software now represent up to 40% of the cost of premium vehicles:”
“The period of very rapid advances after 1700 was ushered in by ingenious practical innovators. But its greatest successes during the nineteenth century were driven by close feedbacks between the growth of scientific knowledge and the design and commercialization of new inventions (Rosenberg and Birdzell 1986; Mokyr 2002; Smil 2005). The energy foundations of nineteenth-century advances included the development of steam engines and their widespread adoption as both stationary and mobile prime movers, iron smelting with coke, the large-scale production of steel, and the introduction of internal combustion engines and of electricity generation. The extent and rapidity of these changes came from a novel combination of these energy innovations with new chemical syntheses and with better modes of organizing factory production.”
“In 1977 GM’s Oldsmobile Toronado was the first production car with an electronic control unit (ECU) to govern spark timing. Four years later GM had about 50,000 lines of engine control software code in its domestic car line (Madden 2015). Now even inexpensive cars have up to 50 ECUs, and some premium brands (including the Mercedes-Benz S class) have up to 100 networked ECUs supported by software containing close to 100 million lines—compared to 5.7 million lines of software needed to operate the F-35, the U.S. Air Force’s joint Strike Fighter, or 6.5 million lines for the Boeing 787, the latest model of the company’s commercial jetliners (Charette 2009).”
“In 1871 about 24% of all workers were in “muscle power” jobs (in agriculture, construction, and industry) and only about 1% were in “caring” professions (in health and teaching, child and home care, and welfare), but by 2011 caring jobs claimed 12% and muscle jobs only 8% of the labor force, and many of today’s muscle jobs, such as cleaning and domestic service and routine factory line jobs, involve mostly mechanized tasks.”
“In 1800 New England farmers (seeding by hand, with ox-drawn wooden plows and brush harrows, sickles, and flails) needed 150–170 hours of labor to produce their wheat harvest. By 1900 in California, horse-drawn gang-plowing, spring-tooth harrowing, and combine harvesting could produce the same amount of wheat in less than nine hours”
