World Environment Day | Ceiling fans are used almost everyday; their power consumption can be cut by half by switching to BLDC tech

A ceiling fan is used at homes almost throughout the year. The amount of electricity needed to run it and the money spent on the bill can be cut by more than a half by switching from a conventional fan to Brushless Direct Current (BLDC) fan.

A 75 Watt conventional fan when used for 16 hours a day consumes 1.2 Kilowatts per hour (kWh). At a unit (kWh) cost of ₹6.50, the electricity bill per annum only for a fan comes up to ₹2857. 

A 32 Watt Brushless Direct Current (BLDC) fan rotates around the same speed. It needs only 0.51 kWh when used for 16 hours. The per annum bill for a BLDC fan is — at the same tariff — is ₹1,208 per annum, which is a more than half the bill for conventional fan, according to information from Southern Power Distribution Company of Telangana Limited (TGSPDCL).

This is one of the methods to reduce demand for power which helps in conserving the environment and saving money as well. The various methods are in focus ahead of the World Environment Day. 

A BLDC fan — which runs on Direct Current — consumes less energy. A BLDC fan costs around double of what a conventional fan does. However, the overall money saved is more by buying a BLDC fan, as per information from TGSPDCL.

Similarly, a conventional tube light of 40 Watt consumes 0.4 kWh. And, a LED Batten of 20Watt consumes 0.2 kWh, according to the Bureau of Energy Efficiency (BEE). 

“Replace traditional incandescent or CFL bulbs with LED lights, which consume 75-80% less electricity. Choose appliances with 5-star or high-star ratings from BEE, such as refrigerators, ACs, and washing machines, which are designed to consume less electricity,” said Musharraf Faruqui, chairman & managing director of TGSPDCL

The senior official said that use of electricity can be reduced if air conditioners are set at 24-26°C, as recommended by BEE, and if filters are cleaned monthly.
