Why super energy efficient ceiling fans?
From Superfan, India’s first super energy efficient ceiling fan
Regular old ceiling fans
Ceiling fans escape one’s mind when thinking about reducing electricity cost. This forgotten appliance contributes significantly to electricity consumption due to its numbers and hours of usage. The following estimation supports this claim. A regular ceiling fan (1200 mm span) consumes about 75 W at the highest speed. There are over 400 million regular ceiling fans in India and each of them creates an electricity demand about 39W* (consumption at medium speed).
Super energy efficient ceiling fans
At present Brushless Direct Current (BLDC) ceiling fan is the popular choice of super energy efficient ceiling fans in India. There are two premier BLDC ceiling fan brands in India – Superfan (Versa Drives Private Limited) and Gorilla fans (Atomberg Technologies)**. These ceiling fans (1200mm span) consume 35W at the highest speed so they save over 50% of electricity consumption.
The higher efficiency comes with no compromise in air delivery. Now consider replacing all the ceiling fans in India with best energy saving ceiling fan. The reduction in electricity demand created by ceiling fans will be:
What are the effects of 10000 MW?
1 tonne of coal is burnt to generate 0.82 units (kWh) of electricity . The burning of 1 tonne of coal produces 1.44 tonnes of carbon dioxide . Therefore, we are burning 1,200 tonnes of coal in vain to meet the extra 10,000MW demand.
Superfan’s mission is to replace the 400+ million ceiling fans in India with super energy efficient ceiling fans and save over 10,000 MW in demand. Join us to be a part of this mission.
As of June 2020, the number of ceiling fans is increased to 500 million (50 Cr) and 3 lakh ton of CO2 is emitted by these 50 Cr regular ceiling fans in a day.
*Typically, the demand is estimated from the energy consumption at medium speed. (Regular fan – 39W, BLDC fans -14W)
**Atomberg Technologies claims that their fan is 28W but it is a marketing gimmick – the fan speed is lowered to showcase the lower power consumption, but at the highest speed their fan consumes 35 W.
