Bitcoin is the only project that is running PoW on a higher scale but even with that higher scale it doesn't come anywhere near in the top list that contributes to environmental damage aka climate change and whatever they claim it to be.
Bitcoin mining energy consumption is for a good cause, it enables the processing of Bitcoin transactions, so in the end the energy used for it is worthwhile cause. Besides it can not be compered to the energy consumed by industries that produces valuable goods. Perhaps countries can increase electric power distribution to carter for it's increasing demand, in this age, practically to get things done requires electricity, so the power consumption need is not perculiar to Bitcoin mining.
