#Eroei

2025-01-29

Peak Oil never went away. There are no large undiscovered pockets of light sweet crude out there, and the oil produced by fracking is essentially highly contaminated sludge.

The price of gasoline & plastics will continue to go up, as reserves are drawn down & processing costs continue to climb.

Inevitably, ordinary people will be priced out of being able to buy gas for their cars. There's no avoiding it.

Only So Much Oil in the Ground… or Gas for that Matter
Chris Rhodes, originally published by Energy Balance
January 29, 2025

A critical component strategy for creating a viable future energy system and addressing climate change, must surely be energy demand reduction (minimisation), e.g. through relocalisation, retrofitting buildings, local food growing, and reducing waste, to curb the size of resource [very much plural] demands, get us below overshoot & avoid collapse (if we can).

The situation will be worsened by the rapidly declining Energy Return on Investment (EROI) for gas & oil liquids which will result in “energy cannibalism”, with less net energy being available for society, as more is consumed by the production of harder to get, diminishing resources...

Meanwhile, shale gas plays may have begun to decline, even as the U.S. is now the world’s largest producer of natural gas & its greatest LNG exporter.

...One day we will run out of oil, it is not today or tomorrow, but one day we will run out of oil and we have to leave oil before oil leaves us, and we have to prepare ourselves for that day. The earlier we start, the better, because all of our economic & social system is based on oil, so to change from that will take a lot of time & a lot of money and we should take this issue very seriously.

"The implications are staggering. A declining EROEI reveals that extraction of energy will be increasingly expensive and eventually, cost-prohibitive. Hydrocarbons will still be in the ground, but the costs of their extraction will continue to climb. This also means that, barring the development of some new type of energy source, society will have to adapt to a much lower energy future."

@whophd @doomscroller @MarkHoltom @peterdutoit that's the way I read it too. I was thinking more about the fact that once you take into account the energy requires to drive this gadget, the #eroei of the primary source is likely negative (since most #fossilfuels are already circling the drain at just over 1.0 – we burnt the good stuff decades ago)

I haven't seen much yet on the fediverse featuring the work of Mr. Hagens, but I usually enjoy his podcast and guests. He recently did a great ~20 minute short on energy return on energy investment, I found it quite enjoyable. He delves into the challenges and weaknesses of some of the different approaches for measurement, and the show notes are packed with some great references and links as well! Beware, this one is quite dense as far as videos go!

@gubi Il cemento ma anche molto altro, le stime sono complesse.

L'#EROEI è eg quanta energia ti resta da un combustibile dopo l'energia spesa per estrarlo. Esempio classico, il petrolio dalle sabbie canadesi è peggio di quello arabo.

L'uranio va "distillato" con processi chimici e fisici energivori per essere usato, quindi il combustibile per le centrali nucleari richiede sempre piú energia per essere prodotto. Quando finiranno le scorte facili (fra pochi decenni), le emissioni schizzeranno.

@gubi È un peccato che anche i giornalisti critici nei confronti del nucleare ripetano a pappagallo questa favoletta delle "emissioni pari quasi a zero". L'#EROEI del nucleare può anche diventare negativo.

"Si al menguante petróleo disponible se le resta la energía requerida para obtenerlo la cosa pinta crudita...
Haced el ejercicio de restar la curva amarilla (la de energía requerida para obtener el crudo) al crudo disponible. ¿Qué tal se ve la caída?"

@dredmorbius let me make a more specific claim. Gathering-hunting has a better #EROEI than all forms of agriculture, because they all massively reduce the complexity and overall productivity of the ecosystems destroyed to make space for them. They *seem* to have a higher EROEI in the short term, only because they mine the natural capital accumulated by those ecosystems before they were destroyed, or use non-renewable inputs (eg fossil fuels) to boost production.

@chebra I'm sceptical. When you factor in the full energy cost of manufacturing and installing solar panels, I'm not sure they even achieve overunity. Plants manufacture and install themselves and if we're talking about generating biogas locally, for local needs, using waste from plants being grown anyway for other purposes, I suspect the #EROEI would be much greater than PV or any other high tech solution.

2019-05-26

@RandomDamage I'm not sure you're fully considering #EROEI (Energy Returned on Energy Invested). When you say
> 1.5 GW nuclear plant

... I presume you're only talking about gross energy produced. To get a fair apples-with-apples comparison with wind, you have to subtract all the energy used to mine, transport, and refine, the fuel used to generate that 1.5 GW. Plus all the energy used to dispose of the waste created in generating it. None of which happens with wind.
