What's actually driving the bill?
Three forces stack: rates (utility prices have outpaced inflation for a decade — SDG&E peak hours now run $0.55–$0.70/kWh, and even mid-cost states see $0.15–$0.30), when you use power (time-of-use plans make 4–9 PM the most expensive hours of the day), and always-on loads you stopped noticing. Most households can cut 10–25% without spending a dollar — and the biggest lever, solar, attacks the rate itself.
What peak power actually costs — 26 utilities, 6 states
The "why is my bill high" answer starts with your utility's peak rate. These are the current peak-window prices across the 53 markets we track — the number every fix above is fighting against:

Rule of thumb: the higher your peak rate, the more load-shifting (free) and solar-plus-battery (big-swing) pay. At SDG&E's $0.55–$0.70 peaks, both are near no-brainers; at Florida's $0.12–$0.17, efficiency fixes carry more of the load.
The 10 fixes, ranked from free to big-swing
| Cost | Fix | Typical bill impact |
|---|---|---|
| Free | Shift usage off the 4–9 PM peak Dishwasher, laundry, EV charging, pool pump — run them before 3 PM or after 9 PM. On time-of-use plans this alone cuts 10–25%. | 10–25% |
| Free | Audit your rate plan Utilities rarely move you to the cheapest plan automatically. Compare your utility's TOU and tiered options against your actual usage pattern — most allow one switch per year. | 5–15% |
| Free | Thermostat discipline Every degree closer to outside temperature saves ~2–3% on cooling/heating. 78°F summer setpoint with a fan beats 72°F without one. | 5–10% |
| Free | Cold-wash laundry + full loads Water heating is most of a wash cycle's cost. Cold cycles clean fine and cut that energy ~90%. | 1–3% |
| Under $100 | Smart power strips + LED holdouts Kill standby loads on entertainment centers and office setups; swap any remaining incandescent/halogen bulbs. | 3–8% |
| Under $500 | Smart thermostat + weatherstripping Scheduling and occupancy sensing capture the savings that discipline forgets. Sealing leaks compounds it. | 5–12% |
| $500–$2,000 | Heat pump water heater Cuts water heating energy 60–70%. Best done when the old tank dies anyway. | 8–12% |
| $1,000–$3,000 | Variable-speed pool pump The single best dollars-per-kWh upgrade in homes with pools — often pays back in under 2 years. | 5–15% (pool homes) |
| Big swing | Solar (with battery on TOU rates) The only fix that attacks the rate itself, not just usage. On high-rate utilities with bills over ~$150/month, cash paybacks run roughly 7–11 years in 2026 even without the expired federal credit. | 50–90% |
| Big swing | Solar + heat pump electrification Pair solar with electrified heating/water and the same panels offset gas costs too — maximum long-run savings, biggest upfront. | 60–95% |
Do them roughly in order. The free tier funds nothing and saves the most per minute of effort; the paid tiers each stand on their own economics; and the big-swing tier is where a bill problem becomes a long-term asset.

Common questions
Why is my electricity bill suddenly so high?
Four usual suspects, in order of likelihood: rate increases (utility rates have risen faster than inflation — SDG&E peak rates now reach $0.55–$0.70/kWh), seasonal usage jumps from AC or heating, being on the wrong rate plan for your usage pattern (time-of-use plans punish 4–9 PM usage), and always-on 'vampire' loads like old refrigerators, pool pumps, and always-on electronics that quietly add 10–20% to bills.
What uses the most electricity in a typical home?
Air conditioning and heating (40–50% in most climates), water heating (~15%), then refrigeration, laundry, lighting, and electronics. Pool pumps are a hidden giant where present — an older single-speed pump can cost $80–$120/month on California rates.
Do time-of-use rate plans save money?
They can, if you shift usage. Utilities charge the most from roughly 4–9 PM. Running the dishwasher, laundry, EV charging, and pool pump before 3 PM or after 9 PM can cut 10–25% off a bill with zero investment. If you can't shift usage, ask your utility whether a tiered (non-TOU) plan is still offered — sometimes it's cheaper for evening-heavy households.
Is solar the answer to a high electric bill?
It's the biggest lever, but the math depends on your rates and bill size. As a rule of thumb in 2026: monthly bills over about $150 on high-rate utilities (California IOUs, or any utility with peak rates above ~$0.30/kWh) usually justify solar even without the expired federal tax credit — cash paybacks run roughly 7–11 years. Below ~$120/month, do the free fixes first.
How much can I save without spending anything?
Typically 10–20%: shift flexible usage off peak hours, set the thermostat 2–3 degrees closer to outdoor temperature, wash clothes cold, fix the rate plan, and unplug or smart-strip always-on loads. None of it requires buying anything.
Does unplugging things really lower the bill?
Standby power is real but modest — usually 5–10% of a bill. The bigger wins in the 'free' category are rate-plan choice and load shifting. Chase those first, then standby loads.
Which utilities have the highest electricity rates in 2026?
Among major Sun Belt utilities, SDG&E in San Diego County is the standout: $0.55–$0.70/kWh during the 4–9 PM peak. California's other utilities run $0.21–$0.38 at peak. Arizona's SRP peaks at $0.24–$0.34, Nevada and Colorado sit in the teens, and Florida and Texas utilities peak around $0.11–$0.18. The higher your peak rate, the more load-shifting and solar pay back.
