In response to the departure of Danny Ryan, a core researcher at the Ethereum Foundation, Vitalik, co-founder of Ethereum, wrote on the X platform: "I am very grateful for your hard work for the Ethereum ecosystem. You are an important force in bringing Ethereum to where it is today. I hope you can be proud to help the world cut electricity consumption by 0.23%, and I hope you can rest well." Vitalik's response included an image that read: "Ethereum's total electricity consumption used to account for 0.23% of the world's total electricity consumption."
