I haven't heard of this sort of proof of work before. Do you have a reference to it?

If you're referring to memory-hard hashing algorithms, I believe those are just resilient to ASICs/GPUs, but still require significant CPU energy. I'm not convinced those would be better for the environment, so if you're referring to those, do you also have an explanation for why they'd draw relatively less power?

Memory-hard hashing algorithms are basically the same idea.

They use less power simply because people are going to spend the same total amount of money in terms of compute hardware + energy, however RAM consumes less energy per per dollar spent on it than ASICs/CPU’s etc.

3W per 8GB of DDR4 is a reasonable baseline. https://www.crucial.com/support/articles-faq-memory/how-much...
