Most data centers refusing to say how much water, electricity they use

    Maybe I'm being naive, but the policies needed here feel quite simple.

    First, since data centers likely need some kind of treated (i.e. demineralized) water, and they want to use local municipal supplies, then they can do so only if they pay full market rate for that water. I would push for them to pay 1% to 5% above market rate to help offset other costs, but market rate at minimum. At no point should homeowners and/or residential customers subsidize this usage.

    Second, commercial users (including data centers) should only get water produced by treatment plants in excess of residential needs. Plants can only treat so much, pipes can only carry so much, and priority goes to residential first.

    Third, ground water is off limits for any commercial/industrial evaporative cooling uses. If data centers want to cool that way, then they need a different source of water.

    Did I miss anything?

      The main thing is evaporative cooling is incredibly wasteful. The water should be returned to the system, if it's going to be used, and not sent into the atmosphere. This is especially important in regions with limited access to water, which, ironically, is where many data centers seem to be located.
