Relying on runoff from mountain watersheds, its water supply is obviously sensitive to
precipitation, but so is its energy footprint. We analyzed Denver Water's annual energy use
and water use alongside local precipitation over a 20-year period from 1995 to 2014. Energy
use generally trended opposite to precipitation: In dry years the system used more energy
than in wet years, even when the energy use was normalized by water volume. The data …
