Is Proof-of-Stake the Green Future of Crypto?

A new report from the Cambridge Centre for Alternative Finance confirms Ethereum<!-- wp:paragraph --><br><p>Ethereum is a technology for building apps and organizations, holding assets, transacting and communicating without being controlled by a central authority.

That equals roughly 0.90 MW of continuous power.<br>Its annual carbon footprint sits at around 2.37 ktCO₂e . Both figures remain more than 99.9% lower than pre-Merge levels.<br>The Merge in September 2022 delivered the biggest drop. Energy consumption fell over 99.9% almost overnight. The network moved from Proof-of-Work levels comparable to a small country down to something closer to the Eiffel Tower’s power draw.<br>Major upgrades since then have improved data handling and validator organisation. Fresh hardware data and better network visibility helped Cambridge researchers refine their estimates.<br>Alexander Neumüller , Research Lead at CCAF, explained: “The drop at the Merge is well documented. What matters now is keeping the picture accurate as the network...
