How we're getting more from less

Good news: "The Economy Keeps Growing, but Americans Are Using Less Steel, Paper, Fertilizer, and Energy."

That whole Reason article is worth reading, but here's an excerpt:

Both the weight of goods entering the [UK] economy and the amounts finally ending up as waste probably began to fall from sometime between 2001 and 2003.… [This] suggests that economic growth in a mature economy does not necessarily increase the pressure on the world's reserves of natural resources and on its physical environment. An advanced country may be able to decouple economic growth and increasing volumes of material goods consumed. A sustainable economy does not necessarily have to be a no-growth economy.…

Up to 1970, consumption of metals in America grew just about in lockstep with the overall economy. In the years since 1970, the economy has continued to grow pretty steadily, but consumption of metals has reversed course and is now decreasing. We're now getting more "economy" from less metal year after year. We'll see a similar great reversal in the use of many other resources.…

I was surprised to learn that total American energy use in 2017 was down almost 2 percent from its 2008 peak, especially since our economy grew by more than 15 percent between those two years. I had walked around with the unexamined assumption that growing economies must consume more energy year after year. This turns out not to be the case anymore—a profound change. Energy use went up in lockstep with economic growth in America for more than a century and a half, from 1800 to 1970. Then the increase in energy use slowed down, and then it turned negative—even as the economy kept growing. Over the last decade, we've gotten more economic output from less energy.

Greenhouse gas emissions have gone down even more quickly than has total energy use.…
