Energy Efficiency Services Limited
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.
Energy conservation in the United States
As furnace efficiency gets higher, appropriate matching of equipment size to distribution system capacity and building load becomes more critical to optimizing equipment ability to maximize efficient operation. Installing much lower output high-efficiency replacement equipment offers opportunity for comfort and savings gains, but improving the building envelope through air sealing and adding more insulation, advanced windows, etc., should be explored concurrently or before replacement equipment design stage. The passive house approach produces superinsulated buildings that approach zero net energy consumption. Improving the building envelope can also be cheaper than replacing a furnace or air conditioner.
