Great (and scary) visualization of 2024 daily temperatures compared to prior years by the BBC today. Evocative of the iconic Joy Division album cover from 1979: https://t.co/o2zLigFV7h

US 20th-century macroeconomic paradigms depended on energy supply. See my paper in Ecological Economics

Statistical tests show that real bituminous coal prices Granger-caused changes to Industrial Production, Money Supply and Income during the Great Depression:

Industrial production fell as real coal prices rose!

[Chris Kennedy @CitiesGuy]

More proof that the Great Depression was caused by an energy transition

Petroleum and farm product prices explain 89% of the decline in commodity prices. Changes to money supply lagged behind.

This paper explaining how the Great Depression was caused by an Energy Transition should interest ecological / biophysical economists too.

Thanks for the tweet Ashlynn @AStillwellPhD
It's been a while since we published this paper - though the conclusions are as relevent as ever.

The US economy added ∼$11 trillion to capital stock from 2004 to 2019 without increasing annual energy use. See the implications for decarbonization in my latest paper: Capital, Energy and Carbon in the United States Economy https://t.co/tXE6RskJZG
