• ... , lumen/watt and life of only 1000 burning hours for the commonly used incandescent bulb), ASSOCHAM suggests that just one LED used in a household in India can save 54 watt per connection at the consumer end when a 6 watt LED replaces a 60 watt incandescent bulb. The consumer would save 16 paisa for energy hour of lighting use at an average domestic tariff of Rs.3/kwh and recover the cost of even a Rs. 500/- premium, that a consumer may have to pay for using one LED, in about 390 days @ 8 hours per day of lighting use. Since the operating life of one LED is around 50,000 hours, it would over this period substitute some 50 incandescent bulbs, cost the consumer a total of only Rs.1900/- in installation and operating costs and save him Rs. 7600/- as compared to the "business-as-usual" scenario where he continues using only incandescent bulbs. And fortunately, efficient lighting devices like LEOs, CFLs and T-5 'tube lights' are now manufactured in India by a number of reputed firms, like Crompton Greaves and Osram, in a variety of shapes, colour outputs and wattages. Mentioning the leadership role of the Ministry of Power's Bureau of Energy Efficiency, ASSOCHAM has commended its innovative programmes like the Energy Star labelling and the "Bachat Lamp Yojana'. SNIPPETS ON ENERGY CONSERVATION By P. Balasubramanian, Publisher, Energy Friendly Fine tune the energy level The latter provides CFLs to households at the price of incandescent bulbs and plans to utilize the Clean Development Mechanism (COM) of the Kyoto Protocol to recover the cost differential between the market price of the CFLs and the price at which they are sold to households. In national interest, and in the interest of the global environment, ASSOCHAM has recommended an aggressive and widespread expansion of this programme to cover all kinds of efficient lighting devices. Concluding ASSOCHAM has suggested that although governmental leadership would be the first requirement to render legitimacy to a sector like energy-efficiency, it is only with the collective efforts of lighting experts, consumers, civil society, and the CFL/LED industry that this vision can be turned into a national movement. The implementation of the model EDPOSTADIN (Standing for Education, Policy support, Standards, Demonstrations and Industry involvement), suggested in a Ph.D. thesis of liT Delhi, was cited and recommended in this regard . Courtesy: ASSOCHAM India (The Associated Chambers of Commerce and Industry of India), 2011, P1 Big industrial houses would have already done energy auditing by internal and external auditors. What they require is only fine tuning of the energy levels by establishing proper dynamic norms for each and every section and achieve further reduction in energy consumption. There is no use for the energy auditor to take credit for the work he does. The saving he achieves should reflect in the SEC (Specific consumption per tonne of product). A drop in the ocean will not be reflected in SEC. Measurement ofparameters The measurement of plant parameters is very important and helps in the decision making process. For example, in a cement industry measurement of fan flow and calculation of efficiency of the fan at plant operating conditions play a key role. The fans in the cement industry consume around 30 per rent of total energy consumption. A single measurement of the parameters will not be sufficient. Quantity? Or Quality? In Malaysia, one of the energy managers during negotiation asked me about the size of the report I was going to submit. I told him I can even give a 5 kg report if that is what he wants. He then kept quiet. Another typical manager in a nearby country! We also sometimes do add a few pages of catalogue to make the report look big on the pretext of helping the customers with ready information if we do not get sufficient ECO's. " The bigger the size of the report, the better is the output" is the mindset of the majority of people. Courtesy: Energy Friendly, Vol. IV, May 2012, P4. 35
