The energy consumption of proof of stake is inherently less of an issue because, unlike proof of work, it does not itself incentivize waste in an escalating vicious feedback loop. In other words, an industry where energy expenditure is an input is categorically different than an industry where energy expenditure is an output, which is the real existential crisis of proof of work.

And proof of stake consumes less energy, but still significant.
