Water and the Trade-offs That Decide Sites
Power and carbon get the headlines, but water quietly vetoes more sites than either. A community will argue about electricity; it will go to war over its aquifer in a drought. And water does not stand alone — the moment you try to save it by cooling with air, your power bill and your carbon footprint climb. Faraday's read: the whole discipline of sustainable siting comes down to trade-offs between three scarce resources, and water is the one that most often forces the hard choice. Understand how a campus spends water, and you understand the constraint most likely to stop it — or to save it, if you site it well.

Why can water be a more decisive siting constraint than power, and how does it trade off against the other resources?
Show the answer
Water rights are often contested, locally permitted, and politically charged, so a scarce or drought-stressed basin can veto a site outright regardless of its power and carbon strengths. It trades off against the others because saving water with air or closed-loop cooling raises electricity use and therefore the power and carbon burden, forcing a site-specific choice about which scarce resource can most afford to be spent.
