Hack 74 · Dominate Your Bills
Audit Your Energy Habits
An energy audit reviews where your electricity, gas, and water actually go, then targets the largest uses with habit changes and small upgrades. Utility bills feel fixed but are substantially behavioural, and monitoring reveals uses that are invisible on a monthly statement. Most households cut $100 to $500 or more a year.
How to do it
- Find your largest energy uses rather than guessing at them.
- Change the few habits behind the biggest ones.
- Make the cheap upgrades that pay back quickly, and skip the rest.
What it typically saves
Typically $100 to $500 or more a year, plus lower emissions.
