Bitcoin's transaction throughput is independent of its energy consumption. If its block size limit was raised to allow Visa-scale transaction throughput, its per transaction energy cost would be 1/1000ths what it is now.
Bitcoin Cash forks Bitcoin to provide a block size limit that allows these kinds of throughput levels, while Ethereum enables both sophisticated transaction compression methods and layer 2 models, that can achieve Visa-scale throughput without raising layer 1 block sizes.
So attacking the cryptocurrency concept based on Bitcoin's peculiar shortcomings is misguided.
