“Every molecule of fossil fuel produced worldwide will be burned by somebody somewhere, and local efforts to restrict consumption merely relocate the enjoyment of that privilege.”
Prior to the widespread proliferation of the steam engine, mining for coal was back-breaking work. The industry relied on human and animal strength, with laborers using primitive tools, to extract the stuff from hand-dug mineshafts. The work was as dangerous as it was dirty, and fatalities were commonplace. Then, a revolution unfolded. A step-change improvement to existing steam engine design, engineered by James Watt, allowed miners to leverage machinery such as pumps, hoists, and ventilation systems to alleviate significant portions of direct human effort. Pumps that used Watt’s engines were particularly effective at draining water from deep mineshafts, making vast and previously inaccessible coal reserves economically viable. The genius of his invention was in delivering far more work per quanta of fuel.
What did these advances in energy efficiency do to the demand for coal? Did society limit itself to doing the same amount of work as it had done before, just more economically so? Quite the contrary.
This is a good one, worth sharing around. More discussion here.
