Coin Carbon Cap – PoW cryptocurrencies ranked by energy efficiency
It doesn&#x27;t mention any PoS solution (which are, compared to PoW) extremely energy efficient. They do mention in the FAQ that they&#x27;re not included since they still depend on some sort of centralization, but as far as I know this is not true for, for example, avalanche (<a href="https:&#x2F;&#x2F;avax.network" rel="nofollow">https:&#x2F;&#x2F;avax.network</a>)<p>It&#x27;s not really clear who is behind this site and if there&#x27;s some hidden agenda. 
Let&#x27;s assume not (but with crypto you can never be sure) and that they will properly consider PoS blockchains if they are as decentralized (or more) as the listed PoW chains.
