Electricity rates are up 18-40% since 2023 and still climbing. Here are 23 evidence-backed tactics to cut your bill 20-40%—ranked by ROI, with payback periods and links to the gear that does the work.
Change your HVAC filter. It costs $10-25, takes 5 minutes, and a clogged filter forces your system to work 5-15% harder, costing the average household $60-180/year. Do it every 60-90 days during heavy heating or cooling seasons.
Most households can cut 20-40% over 90 days by stacking the right tactics: smart thermostat (8-15% HVAC reduction), phantom load elimination ($80-300/year), shopping the supply rate in deregulated states ($80-400/year), and one or two larger investments like a heat pump water heater or variable-speed pool pump. Expect $500-1,500/year in annual savings on a typical $1,800-3,600 annual bill.
At 2026 rates, solar payback periods are 2-4 years shorter than they were in 2022—typically 7-12 years with the 30% federal tax credit. But economics depend heavily on your state's net metering rules. California (NEM 3.0), Florida, Nevada, and Arizona have less favorable export rates than they used to. Get quotes only after you understand your utility's specific NEM tariff.
Only if you can shift major loads to off-peak hours AND you're typically not home (or actively running AC, dishwasher, dryer) during 4-9pm. For work-from-home households with kids, traditional flat rates usually win. Always ask your utility for a free rate comparison based on your last 12 months of actual usage before switching.
Supply is the cost of the electricity itself (generation). Delivery is what your utility charges to move it from the grid to your house. In deregulated states (TX, PA, OH, IL, MA, NJ, NY, MD, CT, others) you can shop only the supply portion—the delivery portion stays with your local utility. Locking a fixed supply rate for 12-36 months insulates you from fuel adjustment volatility.
Yes for most U.S. households. They cut water-heating cost 60-70% (typical savings $300-550/year) and the 30% federal tax credit plus state and utility rebates often cover 40-60% of the $1,600-2,800 install. Payback is 3-5 years; lifetime savings $4,000-9,000. Best fit: garages, basements, or utility rooms in moderate climates. See our heat pump water heater hub.
Top red flags: estimated meter reads two months in a row, billing period over 33 days, fuel adjustment line item that jumped >30% with no rate-case notification, rate schedule that doesn't match your usage pattern. Verifying a bill once per quarter catches most errors. Upload a bill at utilitycheck.co to run the full check automatically.
