GREEN LASH

Ancient civilizations routinely relied on shackled human muscle. It took the energy of slaves to plant crops, clothe emperors, and build cities. In the early nineteenth century, the slave trade became one of the most profitable enterprises on the planet, and slaveholders viewed religious critics as hostilely as oil companies now regard environmentalists. Yet when the abolition movement finally triumphed in the 1850s, it had an invisible ally: coal and oil. As the world's most portable and versatile workers, fossil fuels dramatically replenished slavery's ranks with combustion engines and other labour-saving tools. Since then, oil has transformed politics, economics, science, agriculture, gender, and even our concept of happiness. However we still behave like slaveholders in the way we use energy, and that urgently needs to change.

Many North Americans and Europeans today enjoy lifestyles as extravagant as those of Caribbean plantation owners. Like slaveholders, we feel entitled to surplus energy and rationalize inequality, even barbarity, to get it. But endless growth is an illusion, and now that half of the world's oil has been burned, our energy slaves are becoming more expensive by the day. What we need is a radical new emancipation movement.
