Could the concept of proof-of-work be extended to prove that work was done cleanly, ie: using only renewable electricity rather than that produced from fossil fuels?
Perhaps renewable electricity producers could issue some sort of signed token which is then incorporated into the blockchain as proof that renewable electricity was purchased?
