Ethereum wants to change from Proof of Work due to several reasons. Primarily, Proof of Work consensus mechanism requires intensive computational power, which leads to high energy consumption. Additionally, as Ethereum grows, the scalability issues associated with Proof of Work become more apparent, affecting transaction speed and efficiency. By shifting to a different consensus mechanism, Ethereum aims to improve its scalability, efficiency, and environmental impact.
