Lower my home energy bills

Help me lower my home energy bills. Home: [e.g. "1980s house, 1,800 sq ft", "apartment on top floor"] Own or rent: [OWN / RENT] Climate: [e.g. "hot summers, mild winters"] Heating, cooling, and water heating: [e.g. "gas furnace, window AC units, electric water heater"] Recent bills: [MONTHLY AMOUNTS or usage, especially the highest months] Habits: [thermostat settings, laundry, who's home during the day, devices left on] Budget for upgrades: [AMOUNT, or "free changes only"] Give me: 1. Where my money is likely going, based on what I've shared (label as estimates; my utility bill or a home energy audit gives the real picture). 2. Free changes this week (thermostat schedule, laundry in cold water, unplugging standby devices, closing curtains at the right times). 3. Low-cost fixes under $100 (weatherstripping, door sweeps, LED bulbs, smart power strips), with renter-friendly options marked. 4. Bigger upgrades worth getting quotes for (insulation, heat pump, water heater) and how to check payback time. 5. Where to look for help: my utility's free or low-cost energy audit, rebates, and government incentive programs. Tell me to confirm current eligibility on official sites; don't invent amounts. 6. A simple monthly tracking table to see what's working. Safety: never use an oven or outdoor heater to heat the home, keep space heaters away from anything flammable and plugged directly into the wall, and keep carbon monoxide alarms working.
