Summary
The greatest energy source for civilization before the steam engine was wind. It powered the global economy in the Age of Sail. Wind-powered sail ships made global shipping fast and cheap by harnessing free, reliable ocean winds to propel large cargo loads over vast distances without needing fuel or frequent stops. It also powered windmills, the factories of the Middle Ages and Renaissance. Windmills allowed for abundant bread by milling flour by turning heavy grindstones with wind-driven sails. They also powered trip hammers to forge iron and steel by lifting and dropping massive weights. We can credit them as well for pumped water, sawed timber, and processed oils, spices, and paper.
Wind is one of most elemental yet overlooked forces shaping our world today, and it is at the center of the human story. Many times it changed history – such as “Protestant Wind” saving England from the Spanish Armada, kamikaze winds halting the Mongol invasions of Japan, and easterlies carrying Chernobyl’s fallout. Wind also powers massive turbines today, but there was a forgotten moment in the 1880s when we could’ve chosen wind power over fossil fuels. It even creates certain types of civilizations. Some historians believe the cleverest and most civilized people lived in places where weather was varied and posed constant challenges.
Today’s guest is Simon Winchester, author of “The Breath of the Gods: The History and Future of the Wind.” We look at how wind—life‐giving and destructive, chaotic and harnessable — has shaped civilization from antiquity to today.
