Under the National Energy Efficient Fan Programme, EESL provides BEE 5 Star rated ceiling fans which are 30% more energy efficient than conventional fans. Fans will be sold for Rs. 1,150 per fan. EESL has distributed 6.2 lakh energy efficient fans under this scheme which will save 2.4 lakh kWh and Rs 8.2 lakh per day to the consumers. The price difference is Rs. 500 which is the primary reason for its low penetration, along with the lack of awareness. With the usage of these energy efficient fans it is estimated that consumer’s electricity bills will reduce by about Rs. 700-730 per year, and recover the extra cost in less than 2 years.
Air conditioned clothing
One advantage of air-cooled clothing is that it requires much less energy to cool people down than to cool down their entire environment. For instance, an air cooled shirt uses 4,400 mAh of power for 8.5 hours on the fastest fan setting, while an average central air conditioning unit uses 3000 to 5000 watts of power. In some cases, the purpose of air-conditioning is not to cool down the objects in the room, but the people. Directly ventilating clothing is therefore far more efficient. A 2012 New York Times article reported that gases commonly used in air conditioning absorb some 2,100 times more infrared radiation per ton than carbon dioxide, and due partly to increasing use of air conditioning in the developing world (particularly in tropical areas like India, Malaysia, Indonesia, Brazil, and southern China), air conditioning is projected to contribute to some 27% of the overall greenhouse gas emissions by 2050. Although there are some ideas for room air conditioning units that do not significantly contribute to producing greenhouse gases, none of those options are yet on the market.
