Cardano energy consumption

Share this    

Are you interested in how Cardano PoS is different from Bitcoin PoW? There are many significant differences and both projects are different advantages and disadvantages. Let's compare them from energy-efficiency side.

Consumption per device 45W
Unique relays 471
Pools 1,317
Estimated Bitcoin yearly consumption 253,300 GWh
Estimated unique devices * 508
Estimated yearly consumption 0.200 GWh
Cardano versus Bitcoin efficiency 1,266,501x

* Based on our live relay analysis. Some pools have 5 relays, others share some relays together, others run multiple pools on a single device, some have more relays under one DNS name etc. Some run failover infrastructure, some have non-public relays. We have tried to factor in an appropriate average of all of these. Our estimation includes all infrastructure - relays, block producers etc.
