As the summer heat sets in, many households turn to fans, coolers, or ACs for relief.
Each of these cooling options consumes varying amounts of electricity, impacting your monthly bill.
Electricity Consumption Calculation
To understand the cost implications, let’s calculate the electricity consumption and monthly bill for each cooling option,
assuming 12 hours of daily usage (4 hours during the day and 8 hours at night) at an electricity rate of Rs. 6 per unit.
Power Consumption per Hour
Below is the consumption per hour (approx):
- Fan: 60 watts
- Cooler: 200 watts
- AC: 1500 watts
You can see difference in per hour consumption.
Daily Electricity Consumption
Daily Electricity requirement as per hourly consumption:
- Fan: 12 hours/day x 60 watts = 720 watts or 0.72 units
- Cooler: 12 hours/day x 200 watts = 2400 watts or 2.4 units
- AC: 12 hours/day x 1500 watts = 18000 watts or 18 units
Above is calculated on 12 hours basis.
Monthly Electricity Bill Calculation
So the total cost per month comes out to be:
- Fan: 0.72 units/day x 30 days x Rs 6 = Rs 129.6 per month
- Cooler: 2.4 units/day x 30 days x Rs 6 = Rs 432 per month
- AC: 18 units/day x 30 days x Rs 6 = Rs 3240 per month
Clearly, AC consumes more Electricity.
This breakdown helps you understand the financial impact of choosing between a fan, cooler,
or AC based on your cooling needs and budget.
