🧮 How to Calculate Electricity Costs

The formula is simple:

Cost = (Watts × Hours / 1000) × Rate per kWh

You divide by 1000 to convert Watts (W) into Kilowatts (kW), as energy companies bill by Kilowatt-hour (kWh).

📺 Typical Power Usage of Appliances

  • LED Light Bulb: 10 Watts
  • Laptop: 50 - 100 Watts
  • Refrigerator: 150 - 400 Watts (runs intermittently)
  • Space Heater: 1500 Watts (High usage!)
  • Central AC: 3000 - 5000 Watts

🌱 Tips to Save on Energy Bills

  • Unplug Phantoms: Devices like TVs and game consoles draw power even when off.
  • Switch to LED: They use 75% less energy than incandescent bulbs.
  • Wash Cold: Heating water accounts for 90% of the energy used by washing machines.

Frequently Asked Questions

Where do I find power consumption?

Look for a sticker on the back or bottom of the appliance. It will list "W" (Watts) or "Amps" and "Volts" (Watts = Amps × Volts).

Does my rate change?

It might. Some plans have "Time of Use" rates where electricity is more expensive during peak evening hours.
