EROI discussions are as a rule of thumb, very messy. Since it's an hot topic (it is many times used as argument against solar deployments) I find very useful this guy here https://t.co/QQQLdVTp64 which comes with this nice scaling factors for solar EROI
@alexandrosM Though PV + battery electric has edge over corn ethanol, net energy analysis (+ other life cycle considerations) also needed on that side of ledger. Despite this being controversial area, don't fall for hand wavy dismissals: https://t.co/J0hHr
@flexibledragnet @simonahac @AnthonyBriggs @jasonhickel Well, they at least use EPBT as marketing then... I don't see much of a difference between EPBT and EROI... https://t.co/PVUP5JeC0s https://t.co/tQwIiZkY4n
@JuttaPaulusRLP @transenv @Fraunhofer Well Fraunhofer says "even lower" because they neglect many factors. They take the EPBT of PV without considering the needed storage. This meta-analysis https://t.co/tg1N1jy8eV shows that doing that can lead to factors
@chrispydog This is a tough field, see e.g. https://t.co/n5eS9WM2Cx. All I'm sure of is that only a tiny minority will come to grips with the whole subject. I'm in the majority.
@clv101 @KenCaldeira To borrow from the Coen brothers, this is no country for old dabblers (like me). See https://t.co/n5eS9WM2Cx for the full glory of its complexities.
RT @mattrooney11: A very good paper on the topic showing why different studies give different answers to the EROI of solar. https://t.co/gu…

I guess it needed to be said: "#NEA findings in a particular context cannot definitively support general statements about #EROI or EPBT of #PV #electricity in all contexts." @georgejetson762 Great paper! https://t.co/avgWPsFZ1X
