This page contains data entry 37774 from the Axioma AXP content repository. The structured data below represents the complete record for this entry.

>To analyze useful-stage EROIs, the researchers built on a previous publication that calculated what it termed final-stage EROIs, which tracked the energy used to get a unit of energy to where it's ready for use—so, all the energetic costs of extraction, processing, and delivery. This information let them track this statistic for the 50-year period from 1970–2020. Then, they built their own country-level energy use database. Since typical efficiencies of various uses are available, that lets them track the useful-stage EROI in each country they have data for.

They went beyond just measuring the fuel itself. They included the energy used by infrastructure to transport that energy and put it to use.

If you go purely by point of acquisition, fossil fuels make a lot of sense. It isn't until you start including the cost in energy of carting around those fossil fuels to the point of use that the inefficiencies really stand out.
