Ethereum's Efficiency Relative to Its Scale. What makes the 7.87 GWh figure genuinely interesting isn't just the raw number — it's the context.

What the Study Doesn't Settle. Cambridge's findings are useful, but they're not the final word.

Ethereum runs on 7.87 gigawatt-hours a year. That's it. For a network handling billions of dollars in transactions daily, that number is pretty striking — and a new study from…

Cambridge assessed multiple PoS networks and ranked them by market-value-adjusted energy intensity.

Before Ethereum switched from proof-of-work to proof-of-stake, its energy consumption was a constant target for critics — regulators, environmentalists, mainstream press.

The Cambridge study's market-value adjustment matters here. A tiny, obscure PoS chain might consume almost no energy — but it also has almost no economic activity running through…

And it's not a small dataset. The study covered a range of PoS networks, not just the top two or three.

The blockchain industry has faced serious pressure over energy use for years. Bitcoin's PoW model remains the loudest target, drawing comparisons to gold mining and small-nation…

Other PoS networks studied by Cambridge sit at varying points on the efficiency curve. Ethereum's position near the bottom — meaning least energy-hungry relative to its market…

Worth noting: Cambridge's methodology focused specifically on market-value-adjusted energy intensity. Networks weren't ranked purely on total consumption.

Broader adoption of PoS across the crypto industry has been slow but steady. Several major networks have either transitioned or are weighing it.
