Cardano Consumes The Least Amount of Electricity Per Node
Recently, the Crypto Carbon Ratings Institute (CCRI) has published a research report indicating that Cardano ($ADA) uses the least amount of electricity per node.
The research Institute focused on the environmental impact of cryptoassets and the Proof-of-Stake (PoS) network. In their study, they found that the Cardano consumes the least amount of electricity per node of all proof-of-stake projects included in the study.
The report described, “This metric depends on the amount of transactions taking place on the respective blockchain, also the overall electricity consumption per transaction further depends on the number of nodes connected to the respective network. Generally, these numbers are expected to go down with an increase in the transaction rate, regardless which blockchain is in use.”
The CCRI also reported that Solana ($SOL) uses the least amount of electricity per transaction of PoS networks at 0.166 Wh. The study analyzed six PoS networks where Solana was the only network that ranked lower in energy-per-transaction than payments behemoth Visa with 1.49 Wh. While other projects such as Algorand ranked third behind Visa at 2.7 Wh, followed by Avalanche, Polkadot, Tezos, and Cardano.
The research of CCRI states that there is a need for electricity for blockchain networks to power their hardware and run the software, even in the absence of transactions.
Even though Solana ranked as the lowest network in the energy consumed per transaction, it was responsible for the largest carbon footprint, at 934 tonnes of CO2 per year, compared to 284 tonnes for Cardano.
