This argument is incredibly tired and inaccurate. The majority of Bitcoin mining happens on renewable power and actually HELPS the renewables industry by making renewables more profitable by buying off-peak and surplus energy.

Additionally, the OP conflates power consumption with emissions.

Home mining of Eth is significantly more harmful because cities are still majority powered by coal and gas. If you want to get mad about cryptocurrency power usage, focus your attention there.
