Why These Seem Harmless but Add Up
- Individually lower wattage, but multiplied over many devices, many hours, including standby, the total can be surprisingly large.
- Older technologies (plasma screens, older incandescent bulbs, older computer components) draw more power.
Standby / Phantom Load
- Many devices draw power even when off or in sleep/standby mode. Collectively this adds up to 5‑10% (or more) of a home’s electricity usage in many cases.
Improving Efficiency
- Replace incandescent bulbs with LED bulbs; use motion / timer switches.
- Turn off devices fully when not in use rather than leaving them on standby.
- Use smart power strips that cut off power entirely.
- Choose energy‐efficient screens, monitors, and electronics.
- Use lower brightness settings; disable unnecessary features.
Bonus Device: Electric Vehicle (EV) Chargers
While not always present in every household yet, EV chargers can easily become among your top electricity consumers if you have one. Charging a vehicle frequently, especially with fast chargers or higher kW levels (e.g. Level 2), adds a large amount of electricity consumption monthly. If your utility has variable rates, charging at off‑peak times can lower cost.
Comparing Energy Consumption: Example Scenarios
To understand how big these differences can be, consider two households:
| Device | Wattage / Load | Daily Use (hours) | Daily kWh | Monthly kWh |
|---|---|---|---|---|
| Air conditioner, 3.5 kW | 8 hours | 28 kWh | ~840 kWh | |
| Tumble dryer, 3 kW | 1 hour daily | 3 kWh | ~90 kWh | |
| Refrigerator/freezer, 0.6 kW average | 24 hours | ~14.4 kWh | ~432 kWh | |
| Electric oven, 2.5 kW | 1 hour daily | 2.5 kWh | ~75 kWh |
You can see that even though the refrigerator has a lower wattage than an AC, because it runs continuously its total kWh adds up fast.

How to Audit Your Own Consumption
To really know which devices are costing you the most, here are steps to conduct an energy audit:
- List all major devices in your household that draw power: HVAC, heaters, fridge, washer/dryer, electronics, etc.
- Check their wattage (on the device label or manual). If not available, estimate based on similar appliances.
- Estimate hours of operation per day/week for each.
- Compute energy usage: wattage × hours ÷ 1000 = kWh.
- Track your utility bill to see actual kWh billed, compare with your estimates.
- Identify worst offenders and set priorities: devices that use a lot of power and are used often should be targeted first.
Practical Tips to Reduce Electricity Consumption
- Replace old appliances with newer, energy‑rated ones.
- Use timers, smart plugs / smart outlets.
- Unplug or shut off devices fully, not just standby.
- Use heating / cooling only when needed; improve insulation.
- Use cold or warm water washes, avoid over‑drying, avoid heating water beyond what’s necessary.
- Use LED lighting; minimize usage of high‑wattage lamps.
- Solar panels or renewable energy systems can offset usage of high‑power devices.
Summary: What Matters Most
- Devices that combine high wattage + long runtime (HVAC, water heaters, refrigerators) are usually your biggest consumption culprits.
- Devices that operate at large power for short periods (tumble dryers, electric ovens) also matter, especially with frequent use.
- Minor devices and standby loads are sneaky—they might not consume much individually but together they can contribute significantly to your electric bill.
- The biggest savings usually come from changing usage behavior (less run‑time, lower temps, turning off standby), upgrading to efficient models, and ensuring your dwelling is well insulated / sealed.
