“The suggestion that the rise and fall of productivity growth is associated with the availability of physical resources such as energy and minerals is clearly one that merits further attention. The similarity between the rise and fall in labour productivity shown… and some recent studies of the energy return on energy invested (EROI) in fossil fuels is striking.”
EROI is a measure of the amount of energy used to extract energy from a particular resource. The more energy one can get out compared to what is put in, the better, and the higher the ‘net energy’ available to society. Lower EROI, however, means that less and less energy can be extracted despite increasing investments of energy.
Recent economic research previously reported by INSURGE suggests that the maximum EROI levels for global oil and gas production were reached around the middle of last century.
“Most EROI studies across multiple countries show declining EROI in the last two to three decades,” says Jackson. “So the idea that the rise and fall in labour productivity growth has something to do with the underlying physical resources is certainly not fanciful.”
There are strong grounds then to recognise that the long-term decline in the rate of economic growth is partly related to industrial civilisation’s intensifying exploitation of material resources on the planet, and the diminishing returns from doing so.
The economic crisis is not just about ‘economics’, narrowly conceived: it is about the human species’ accelerating breach of planetary boundaries."<br><br><a href="https://medium.com/insurge-intelligence/govt-economic-advisor-warns-british-defence-planners-that-growth-is-ending-abf806f17845">https://medium.com/insurge-intelligence/govt-economic-advisor-warns-british-defence-planners-that-growth-is-ending-abf806f17845</a><br><br>Sent from Pocket - <a href="https://getpocket.com/go?src=email">Get it free!</a></div><br><br><div id="AppleMailSignature"><div>Antony Barry</div><div>antonybbarry at <a href="http://me.com">me.com</a></div><div>Mob +61 433 652 400</div></div></body></html>
