Worth keeping in mind: blockchain does not necessarily mean energy-intense, there are many blockchains that work based on history. They use proof-of-stake instead of proof-of-work. They are not without problems and there are a lot of proof-of-stake-SomehingElse to address those, but it is possible to make it work.
