How much more energy efficient is the Cardano/ADA blockchain over the Ethereum/ETH blockchain? Stats?
Where can we read more about the exact statistics?
Thank you!
Elliot, 18 days and no replies to your important question. Sadly the environment does not at this time even get mentioned in Cardano’s mission statement. Cardano (according to that) and its users (according to lack of response to your question) do not generally appear to consider the environment a priority. I share your concern, but then I am only here ‘just looking’ to find out whether Cardano can be regarded as a sufficiently ethical system to be involved in yet. Sadly I have been disappointed, as you have probably been too.
Hi @Alan_T_Cooper I don’t think the situation is that negative 
He is looking for “exact statistics”. I guess to answer that it requires some deep research, and those numbers are so unknown that it’s hard to precisely measure them. Operator’s A setup may differ from Operator B’s setup, and so will the energy consumption, etc…
There are many articles on the internet that compare energy consumption between a Proof of Work protocol vs. a Proof of Stake. Some researchers believe that the energy consumption of proof of stake is 99.99 percent lower than proof of work…
Until someone comes up with “exact statistics” best thing would be looking up Google for “Proof of stake vs. proof of work”.
According to pooltool.io there are currently 2875 active pools. Let us say we have an average of 2.5 nodes per pool. That’s about 7187 machines involved in producing blocks that can be as small as a raspberry pi 4 and don’t need huge processing power.

Of course, Cardano is still much smaller in terms of transaction count per day compared to Etherium and Bitcoin.
Please let me know if I missed something.
Thank you Alan! Yes I was hoping for an answer–a ballpark estimate would be great! Let’s see if I can put one together in the next few days!
Thank you MCRIO! Yes I was hoping for an answer–a ballpark estimate would be great! Let’s see if I can put one together in the next few days! Any estimate would be great too!
