'''Myth:''' "Crypto mining is not a problem if it's done with green energy."

'''Fact:''' Green energy is in [[energy#Energy supply|extremely short supply]]. Using it for crypto mining means there's less available for other domains, which end up using fossil fuels instead.
* Note: There ''are'' a handful of exceptions to this, in places where there's an overabundance renewable electricity generated and absolutely no other way to use it{{x|nor store it, nor connect it to some other geographic area that could use it}}. Actual situations like this are quite rare. Even where they exist, we still haven't accounted for the energy needed to manufacture the vast amounts of electronics{{x|many of which are chips that could be used for other purposes}} used for the mining. Also, all forms of crypto mining will increase the mining-difficulty on the global network, which means that in other areas, more fossil fuels are used in mining same amount of currency.
