Stellar Lumens (XLM) utilizes reliable nodes to authenticate its trades rather than PoW or PoS. This eco-friendly cryptocurrency platform established itself as a feasible choice for financial transactions. The Stellar network’s efficiency makes it an excellent choice for investments in a carbon-neutral cryptocurrency. It also enables the creation of tokens, which enables the formation of sustainability efforts and incentives.

19. Dogecoin

Dogecoin most eco friendly cryptocurrency

Dogecoin, one of the most popular cryptocurrencies, has been regarded as a green crypto substitute for Bitcoin. The use of PoW consensus reduces its efficiency when compared to other green crypto options.

Dogecoin’s estimated energy consumption per transaction is 0.12 kWh, which is far from the most energy-efficient crypto exchange rating currently available. Dogecoin, on the other hand, is working to improve its environmental standing and is one of the leading seeds inside the low-energy bitcoin sector. Dogecoin may have the staying power needed to cement its place as an eco-friendly cryptocurrency with the help of Tesla CEO Elon Musk and other supporters.

20. Avalanche – most eco friendly cryptocurrency


A smart contract platform that uses a PoS algorithm as well as the native token $AVAX. The cryptocurrency is restricted to 720 million AVAX coins in trade. However, It has a structure that enables the deployment of custom publicly or privately blockchains as subnets, and all these subnets can handle around 4,500 times per second at a reduced cost than networks like Ethereum.

Avalanche is scalable, decentralized, secure, and energy-efficient, and it is compatible with Ethereum’s programming language. For such reasons, it is technologically advanced working on DeFi projects, games, NFTs, as well as other projects. 

This is the list of 20 more energy-efficient cryptocurrencies. Most of the cryptocurrencies that use PoS( proof-of-stake) methods need less energy consumption in contrast to the PoW( proof-of-work) method. However, some cryptos have found an even more cost-effective way like the PoC ( proof-of-commitment) method. 

With all these efforts in energy saving and less CO2 emission, the cryptocurrency will soon be completely environmentally friendly as per the hopes.
