This I understand but not all inputs are equal across the world (electricity cost). Wouldn’t it be more beneficial to reward them based on efficiency as it relates to computational power / energy consumption?

First post. Not super savvy when it comes to coding and all that but I’ve been tinkering in my head around the energy usage that many regulators have with proof of work. I know a lot of this is unfounded but it gave me an idea. Theoretically, would it be possible to either amend the bitcoin code or propose a fork whereas miners would be reward based on the efficiency of their mining rig? Sort or hash/watt
