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.
Computer fan
Used to aerate the case of the computer. The components inside the case cannot dissipate heat efficiently if the surrounding air is too hot. Case fans move air through the case, usually drawing cooler outside air in through the front or bottom (where it may also be drawn over the internal hard drive racks) and expelling it through the top or rear. Some ATX tower cases have one or more vents and mounting points in the left side panel where one or more fans may be installed to blow cool air directly onto the motherboard components and expansions cards, which are ones of the largest heat sources.
