>>105664763Why are we measuring environment impact in water consumption when the benchmark is total power consumption and accompanying CO2 emission, in any case? Either way, a dollar bill is a good proxy for the energy intake and carbon emission. There is more or less linear relationship between the cost of something and how its existence ended up emitting the gas. The use of water is a non-issue because like you said it just cycles around, it doesn't disappear or accumulate.
