#EROI (Energy Return on Investment) measures the usable energy gained from a source divided by the energy invested to extract, process, and deliver it. Clean energy has superior EROI’s.

What you get back vs what you put in. The ratio always declines.
Luxury fragrance specAd about that feeling.

The old argument “ #renewable #energy #EROI isn’t high enough for modern #civilization” was always at best weak and often just outdated bullcrap, but it is great to have fresh numbers and more evidence. #collapse

17/ 📘 Along the full article doi.org/10.1016/j.sp... Includes extensive supplementary data supporting regional EROI projections and long-term energy transition insights.
Authors welcome #scientificengagement 🧠 on #EROI, #EnergyTransition, and #NetZero systems.

15/ 📊 Main finding: Regional #EROI trends are shaped more by energy transition pathways than by uneven resource distribution. Prioritising low-cost #RenewableEnergy is key for a net-zero, cost-effective transition, while also reducing the risk of a renewable resource curse.

13/ Renouncing finite fuels & prioritising low-cost #Renewables reduces the risk of a #resourcecurse by 2050 & enables cost-effective, carbon-neutral power. In #IEAscenarios, fuel switching (coal → gas/nuclear) poses the highest sustainability risk, affecting regional #EROI.

12/ Regional differences matter 🌍. Hydropower-rich #SouthAmerica achieves the highest #EROI, while regions with rapid #solarPV expansion see sharper short-term declines due to storage needs 🔋.

8/ Regional #EROI trends in #IEAscenarios are mostly stable by 2050, but some regions face critical shifts. #Europe declines early due to coal → gas & nuclear, later rises with renewables. #MENA rises as gas shifts to PV & nuclear. Other regions show minor changes.

7/ As variable renewable energy shares increase, enabling technologies (#batteries🔋, #hydrogen, gas storage, #electrolysis) expand rapidly, leading to a temporary decline 📉 in systemwide #EROI during the transition phase.

6/ ⚡ Low-cost #renewabletechnologies, particularly 🌞 #solarPV and 💨 wind power, consistently dominate the energy mix, whereas other natural energy resources play a secondary role in shaping long-term trends in #EROI.

5/ Results show that no regional #EROI falls below 10 in the power sector, a commonly cited global viability threshold, indicating that regional #EnergyTransitions are techno-economically feasible even under constrained natural resources.

3/ 🆕 The key novelty lies in linking regional #PowerSystemModelling with a systemwide #EROI framework, allowing us to test whether a sustainable #energy transition is feasible regionally under real resource and policy constraints, without encountering RE-based #resourcecurse.

2/ 🔬The study applies a systemwide #EROI methodology (doi.org/10.1038/s414...), integrating #LCA with energy system modelling outputs (doi.org/10.1016/j.ap...), capturing energy investments & net energy supply consistently at the electricity level (doi.org/10.1016/j.se...).

1/ New research from @lut.fi shows how uneven natural resource distribution shapes regional #EROI during the energy transition. doi.org/10.1029/2025.... 🌍 Can regions transition to sustainable #NetZero energy systems without triggering a #RenewableEnergy-based #resourcecurse? 📢
