How to Calculate Electric Consumption of Appliances in the UAE (Complete Guide for Residents)
Managing your monthly electricity bill in the UAE doesn’t have to be confusing or costly. Whether you live in Dubai, Abu Dhabi, Sharjah, or Ajman, understanding how to calculate electric consumption of appliances can help you control your expenses, identify energy-hungry devices, and make your home more efficient.
At Emirates Appliances, we help UAE residents make smarter appliance choices — from energy-efficient refrigerators to smart air conditioners — so you can save more while living sustainably.
What Is Electric Consumption?
Electric consumption simply means how much electricity your appliances use over time. It’s measured in kilowatt-hours (kWh) — the same unit DEWA, SEWA, and FEWA use on your monthly bills.
For example, when your air conditioner runs for 8 hours, or your fridge stays on 24/7, each uses a different amount of power that contributes to your total electricity cost.
Why Should You Calculate Your Appliance Energy Usage?
Knowing how to calculate electric consumption of appliances gives you control over:
- Cost Savings: Identify high-energy devices and adjust their usage to lower your bills.
- Sustainability: Reduce unnecessary power waste and support a greener UAE.
- Smart Choices: When buying or upgrading, you can choose energy-efficient appliances that save money long-term.
Thinking of upgrading your old refrigerator? You can buy used fridge models or explore our wide range of efficient options at Emirates Appliances.
Step-by-Step: How to Calculate Electricity Consumption
1. Find the Appliance’s Power Rating
Every appliance has a label showing its power usage in watts (W) or kilowatts (kW).
For example:
- Air Conditioner: 2,000W (2kW)
- Refrigerator: 150W (0.15kW)
If you’re planning to buy or sell used fridges, check our detailed guide for UAE residents.
2. Estimate Daily Usage Hours
Note how many hours per day each appliance runs:
- Air Conditioner: 8 hours
- Refrigerator: 24 hours
- Washing Machine: 1 hour
Tracking this helps you estimate how much each device adds to your bill.
3. Use the Formula
The basic formula to calculate energy use is:
Energy Consumption (kWh) = Power Rating (kW) × Usage Time (hours)
So, if your air conditioner is 2kW and you use it for 8 hours daily:
→ 2 × 8 = 16 kWh per day.
To simplify your calculations, you can also use our online energy consumption tools at Emirates Appliances.
Example Energy Calculations
| Appliance | Power (kW) | Daily Hours | Daily Use (kWh) | Monthly (kWh) |
|---|---|---|---|---|
| Air Conditioner | 2.0 | 8 | 16 | 480 |
| Refrigerator | 0.15 | 24 | 3.6 | 108 |
| Washing Machine | 1.5 | 1 | 1.5 | 45 |
Using this table, you can estimate your own appliance energy costs and find ways to reduce them.
