Bill by bill
Thermostat schedule, LED swaps, cold wash, phantom-load strip. Full guide with DOE-sourced numbers: How to lower your electric bill.
Heating dominates: setback schedule, a serviced furnace, sealed drafts and a water heater at 120°F.
Call retention yearly for the promo rate; downgrade speed tiers you don't use; buy your own modem instead of renting ($10-$15/month back).
Prepaid carriers on the same networks at half the price; family plans split further. Autopay discounts are free money.
Fix running toilets (silent $20-$50/month leaks), shorter showers, full loads only; check municipal senior/income discounts.

When the bill is unpayable
Payment plans exist at nearly every utility, and shutoff protections are stronger for people who called early.
Federal energy assistance through your state — heating, cooling, and crisis help for qualifying households. Funds are seasonal; apply early.
The FCC's phone/internet discount for qualifying households — a working number is job infrastructure.
Local utility funds (churches, community action, the utility's own charity arm) that no national website lists.
