A kitchen table at evening covered with a fanned stack of blank statements, a highlighter, a calculator and a phone, with a hand mid-note.

    The Energy and Water Audit

    The quantity half of every usage-billed charge, done with a $30 meter, a flashlight and one Saturday.

    The lessons

    All 4, in the order they are read.

    1. 1. Find the biggest load first
      A handful of appliances account for most of a household's power, and measuring beats guessing every single time.
    2. 2. The running toilet and the leak
      A large water bill is almost never behaviour; it is a leak, and the meter tells you within twenty minutes whether you have one.
    3. 3. Envelope before equipment
      Air sealing and insulation return more per dollar than replacing a working furnace, and almost nobody does them in that order.
    4. 4. The rebate that pays for it
      Utilities and states publish rebate schedules that routinely cover a third to all of the work, and they are claimed before the job, not after.

    The worksheet

    Load and leak audit

    Top half: every plug load you measured, ranked by annual cost. Bottom half: the water tests, with a result and a date. A blank result line is a test you did not run, and the most expensive line in any water bill is the test nobody ran.
