Indeed, akin to manufacturing Duracell batteries. A useful and profitable process - but lets not be kidding ourselves we can run the world on Duracells.
Absolutely. it can only work so long as the overall EROEI for our society is favourable.

And something that brings EROEI nearer zero:
As of 2009, the Department of Defense emptied 360,000 barrels of oil a day. And that number skyrockets during a war.
…burned largely to 'protect' dwindling resources. Errrmmm….

Is that article correct? It mentions
high octane jet fuel
, well that's not likely to exist. Jet fuel is paraffin, high octane is Avgas (petrol). How many other inaccuracies exist?

The principle is sound though. If defence policy is predicated on safeguarding oil supplies, it makes sense to include the energy used in such defence as part of the "energy invested" in the EROEI calculation.

Indigenous supplies have less need for such defence, and therefore have an inherently higher EROEI! :)

ETA; this over-simplification of course ignores the positive impact on GDP of additional sales of McDonalds burgers as a side-effect of the westernisation of the "protected" oil-producing nations. :wink:
