When we buy electronics equipment like refrigerators and air conditioners, we always select BEE 5-Star rated equipment.
The reason is simple. A 5-star rated appliance consumes less energy than a device with a lower rating.
Now, we consider that ACs and refrigerators guzzle electricity. Hence, it is in the fitness of things that we should not mind spending something more to gain in the long run.
However, do we do the same in case we venture to purchase ceiling fans?
Unfortunately, the broad response is in the negative. We generally feel that ceiling fans do not consume much electricity.
Secondly, we have more than one ceiling fan running at all times in our homes.

5-Star Rated Ceiling Fans
The need to conserve electricity brings us to the discussion of using BEE 5-star rated ceiling fans. Yes, the Bureau of Energy Efficiency (BEE) rates ceiling fans as well on the scale of 1 to 5.
Other than this fact, there is nothing to suggest that the regular ceiling fans are better than the 5-star rated fans. Let us look at some of the numbers to get a clear idea.
The regular ceiling fans consume 75 watts whereas the consumption of the 5-star rated fans is 50 watts. It is a definite savings of more than 30%. Some of the latest generation 5-star rated fans have a rating of 45 watts.
Consider that a ceiling fan works for a minimum of 12 hours a day. Let the numbers do the talking now.
|Traditional fan||BEE 5-Star rated fan|
|Wattage||75 Watts||50 Watts|
|Units consumed in a day||0.9||0.6|
|Units consumed in one month||27||18|
|Power consumption cost @ an average cost of ₹ 5 per unit||₹ 1640||₹ 1095|
This table shows that you can save a minimum of ₹ 500 to ₹ 550 when you switch over to the 5-star rated ceiling fans.
The difference in the initial cost of the fans is around ₹ 600. Therefore, you end up recovering the difference in the price within one year.
Usually, people do not replace ceiling fans in the house for a minimum of 5 to 6 years. Under such circumstances, you can save a sizeable amount by way of reduction in power consumption.
How does BEE rate ceiling fans?
Any ratio above 4 entitles the fan to have a 5-star rating. Consider the classification of the fans we have discussed in the example.
- Regular ceiling fan – 250/75 = 3.33
- 5-Star rated fan – 220/50 = 4.4
What is the difference between a traditional fan and the 5-star rated ceiling fan?
Some disadvantages of the 5-star rated fans
Some of the ceiling fan manufacturers have started compromising on the air delivery and the RPM to reduce power consumption.
It results in the reduction of the optimum speed of the fans. It is a disadvantage in a country like India because the fans run at full speed in India at all times. The reduction in the speed reduces the delivery of air thereby not providing the necessary comfort for the consumer.
If the reduction in power consumption is what you are looking for, the 5-star rated ceiling fans are the ideal choice.
