    If you want to have rather green cryptos, you need to exclude those who rely on proof-of-work to secure the network.
    Btw. Ethereum showed that a transition from proof-of-work to proof-of-stake is possible.
    If you’re not interested in the complexities that a lot of cryptos have, because you just want to transfer value efficiently, have a look at Nano (https://nano.org)

      I have heard nano uses a lot less energy compared to Crypto. Though how does it compare to visa/traditional payment systems?

          Nano has alwas has a computational part associated with transactions. It once was used to prioritize transactions. Nano has evolved to a different prioritization scheme. That computational part will be phased out.
          The lightning network is a silly attempt to merge bad parts of cryptocurrencies with bad parts of traditional finance: you need the electric energy guzzling Bitcoin and middlemen just like in traditional finance - or would you care to open and close your own channels, pay watchtowers etc. or “simply” use the channels of middlemen?
          And how would you have cheap transactions without those middlemen, if operating your own channels requires transactions on layer 1?

              I stated the reason for it being phased in: prioritizing transactions.

              Tell me how to keep a channel open without risking loss of funds through flood and loot attacks.

        Indeed it does use little energy, because its consensus is in some ways similar to PoS, so there’s no mining involved. If you want to know more about it, have a look here: https://docs.nano.org/protocol-design/orv-consensus/
        I believe that the Nano network can process around 100 transactions per second; at least that’s a result from throughput tests I remember. That’s way less than VISA can do, but a lot more than most other cryptocurrencies can process.
        And in difference to the vast majority of cryptocurrencies, Nano has no built-in limits of transactions per second. As soon as hardware gets more powerful (faster CPUs, faster network connection, faster SSDs), Nano gets faster!
