The passage around this formula
Water usage effectiveness fills that second gap, introduced by the same organization a few years before this decade’s AI buildout made it urgent: . reported in litres per kilowatt-hour and deliberately built to use “the same value… as the denominator for this new metric” as PUE, “to both ensure the metrics stay linked and speed their adoption” [ 6 ] . WUE exists because the cheapest way to reject a given amount of heat is very often evaporative — cooling towers and adiabatic assistance work against the wet-bulb temperature rather than the dry-bulb temperature, so they can reach a lower effective cooling temperature for less fan and compressor energy than a fully dry system…
Learn the underlying idea
A fraction a/b means a divided by b. The top number is the numerator; the bottom number is the denominator, and it cannot be zero.
