This article on EROI however makes the cardinal error of using 5-6 year old data on PV/wind costs in its analysis. That is equivalent to using 50 year old data for coal/gas plant efficiency. EROI of PV solar and wind is more like 20+ using latest LCOE (eg Lazard 12.0).https://twitter.com/emahlee/status/1162180547369562112 …
Could you spell this out for me Harry? I'm not following. that EROI for solar and wind is 20:1 (or higher) is a good thing, yes? Do I understand that correctly?

The bigger number the better - it’s the value of energy created divided by energy needed to create it -it’s notoriously been misused as oil and gas EROI often ignores costs of extraction, refining etc. In this case they include that - but then use antiquated solar costs

Oh, so fossil fuel EROI is much worse than previously thought (as the study shows), and (as you've pointed out), with more recent data, solar and wind EROI is much better. Though the study shows 6:1 it's actually 20:1 or higher!
