This is simply wrong. We produce vastly more GDP per unit of energy than we did a century ago, and will do the same a century from now.

The size of an economy is a measure of what people will pay for a good. It's not a measure of how big a pile of steel you can make. The most expensive goods nowadays, services and computing, do not take vast piles of resources. In fact, the most expensive computers use the LEAST energy per unit of computation.

While GDP/energy ratios have improved in some countries:

1. Total energy usage has increased.

2. There's been significant increased inequality within those nations. Particularly the US, also major industrial countries (G-7, OECD, etc.).

3. Many of these countries are exporting heavy manufacturing, with energy and other resource utilisation, and pollution generation, particularly to China and India.

"The true raw material footprint of nations ", September 3, 2013. "The study, involving researchers from UNSW, CSIRO, the University of Sydney, and the University of California, Santa Barbara, was published today in the US journal Proceedings of the National Academy of Sciences. It reveals that the decoupling of natural resources from economic growth has been exaggerated."

It's very wrong and often echoed here unfortunately.

Here is a graph is US energy intensity:

The US uses less than half the amount of energy per unit of GDP than it did in 1950.
