The reliance on renewable energy for profitable mining farms actually makes POW mining more sustainable and reliable than stake mining

Just an idea I posit. POS has lots of potential but the actual worldly benefits of POW might make it more sustainable in the long haul. The only thing that still has to be taken into consideration is the high barrier for entry to mining versus the cheaper and easier staking.

Stake mining is far more reliable since it doesn't require a significant amount of fixed costs in the form of mining rigs. The energy usage in Proof of Stake is far lower than Proof of Work, even if renewable energy is utilized in Proof of Work.
