Energy savings
Cut your electric bill without guessing
Start with the loads that dominate your bill, then work down the list. Every recommendation here comes with the math behind it.
Where your electricity actually goes
Priorities matter more than effort. Fixing a small load perfectly saves less than improving a large one slightly.
| Category | Typical share | What to do first |
|---|---|---|
| Heating & cooling | Largest single category for most US homes | Setbacks, filters, duct sealing, smart thermostat |
| Water heating | Typically the second largest | Lower tank temp, low-flow showerheads, pipe insulation |
| Appliances & electronics | Refrigeration, laundry, entertainment | Full loads, cold washes, metering plugs on idle devices |
| Lighting | Small share but the cheapest to fix | LED swaps in the highest-hour fixtures first |

Estimated annual savings

558.5 kWh of electricity avoided per year
- Current bulbs / year
- $111.69
- 657 kWh
- After LED swap / year
- $16.75
- 98.5 kWh
How this is calculated
Annual kWh = watts ÷ 1,000 × hours per day × 365 × number of bulbs. Cost = kWh × your rate.
(60W − 9W) ÷ 1000 × 1,095 hrs × 10 bulbs × $0.17/kWh = $94.94
Educational estimate only. Real results vary with actual usage, bulb quality, tiered utility rates and seasonal heating or cooling effects. This is not a guarantee of savings.
