Frequently Asked Questions
How do I calculate electricity cost?
Cost = (Watts × Hours per day × Days) ÷ 1000 × Rate per kWh. Example: a 1000W air conditioner running 8 hours/day at $0.12/kWh costs 1000 × 8 × 30 ÷ 1000 × 0.12 = $28.80/month.
What are the most expensive appliances to run?
Electric water heater: 4000-5000W. Electric dryer: 5000W. Air conditioner: 900-5000W. Electric oven: 2000-5000W. Refrigerator: 100-400W (runs 24/7). Space heater: 750-1500W.
How can I reduce electricity bills?
Replace incandescent bulbs with LEDs (saves 75%). Unplug devices on standby — they still use power. Use cold water for laundry. Set AC 2-3°C higher in summer. Run dishwasher and washing machine on off-peak hours.
