THE NEW INDIAN EXPRESSEnergy Conservation Week to be Observed from December 14ByExpress News Service - HYDERABADPublished:14th December 2013 09:02 AMLast Updated:14th December 2013 09:02 AMEmail0With the state and Central governments keen on promoting solar power and focusing on promotion of energy conservation in a big way, the New and Renewable Energy Development Corporation of Andhra Pradesh (NREDCAP) is organising Energy Conservation Week (ECW) at the Institution of Engineers (India) here from December 14 to 20.During the week, seminars, workshops and competitions will be organised in coordination with the National Productivity Council, Petroleum Conservation Research Associations, Energy Conservation Mission, FAPCCI and OU College of Engineering among others.Addressing a press conference here on Friday, NREDCAP managing director M Kamalakar Babu said that the ECW is aimed to disseminate energy conservation and efficiency measures.Rural energy awareness programme for school and college students will be held from December 14 to 17, Energy Conservation Walk on December 15, followed by awareness campaign at JNTU on Dec 16, workshop on EC measures in domestic sector on December 17, industries sector on December 18), in buildings on Dec 19, and Save Energy calendar cum pocket guide will be released on Dec 20.He said State Energy Conservation Awards-2013 will be presented to various organisations that include government departments, municipalities, corporations, universities, colleges, industries and others on December 20.

CommentsI have had been advocating energy conservation since long. Apart from Energy generation from Renewables, Energy Saving is the need of the hour in India. A Novel Scheme to replace Old and inefficient agricultural pump sets: Out of the 26 Million Agricultural pumpsets in the country many are old and inefficient. The power tariff for farmers is minimal. Electricity is a high grade energy which is needed in industries, domestic purposes, computers etc. A scheme can be chalked out to replace the inefficient motors by efficient ones. The cost of a 5 HP Electric motor because is about Rs 20,000.A subsidy of Rs 15,000 can be provided to replace these inefficient motors. This yields quick results and Energy conservation is better than energy generation. Each Kwh saved is each Kwh generated (1 US$= Rs 60). There must be some contribution from the beneficiary otherwise he wont take care of the system. Giving free leads to misuse. In 80s the then Department of Non-Conventional Energy Sources(Now MNRE) under Demonstration Programme installed over 4000 Water Pumping Mills free of cost. In Andhra Pradesh about 500 were installed. At that time a windmill was costing Rs 20,000. A reliable windmill costs around Rs 80,000 at that time. Infact in our Filelds in Muthukur, Nellore District, Andhra Pradesh 2 Wind mills were installed. None of the windmills worked and vanished in no time. Based on several studies carried out on agricultural pumpset efficiency, it has been found that the pump efficiency varies from 25-35% due to various factors. By adopting BEE star lebelled agricultural pumpsets, the efficiency can be enhanced upto 50-52%. It is estimated that, by replacement of existing pumps with the BEE star labelled pumps, the achievable saving potential is 30-40% and sectoral saving potential works out to be 4.34 BU per year. Instead of huge investment on New Power projects, The Government of India and different state Governments can jointly plan a scheme to replace the existing old and inefficient agricultural pumpsets with efficient ones. This yields quick results. Energy conservation refers to reducing energy consumption through using less of an energy service. Energy conservation differs from efficient energy use, which refers to using less energy for a constant service. For example, driving less is an example of energy conservation. Driving the same amount with a higher mileage vehicle is an example of energy efficiency. Energy conservation and efficiency are both energy reduction techniques. Even though energy conservation reduces energy services, it can result in increased, environmental quality, national security, and personal financial security. It is at the top of the sustainable energy hierarchy. One of the primary ways to improve energy conservation in buildings is to use an energy audit. An energy audit is an inspection and analysis of energy use and flows for energy conservation in a building, process or system to reduce the amount of energy input into the system without negatively affecting the output(s). This is normally accomplished by trained professionals and can be part of some of the national programs discussed above. In addition, recent development of smartphone apps enable homeowners to complete relatively sophisticated energy audits themselves. Building technologies and smart meters can allow energy users, business and residential, to see graphically the impact their energy use can have in their workplace or homes. Advanced real-time energy metering is able to help people save energy by their actions. Elements of passive solar design, shown in a direct gain application. In passive solar building design, windows, walls, and floors are made to collect, store, and distribute solar energy in the form of heat in the winter and reject solar heat in the summer. This is called passive solar design or climatic design because, unlike active solar heating systems, it doesn't involve the use of mechanical and electrical devices. The key to designing a passive solar building is to best take advantage of the local climate. Elements to be considered include window placement and glazing type, thermal insulation, thermal mass, and shading. Passive solar design techniques can be applied most easily to new buildings, but existing buildings can be retrofitted. Energy Saving in Lighting. One innovation that saves enormous power in light is READING SOLAR LIGHT dual powered. Normally in India students read under a 40 Watt Fluorescent bulb. In school and college hostels one Fluorescent bulb for 4 to 6 people. A Fluorescent bulb consumes 40 Watts. Its life time is short. In voltage fluctuations (common in some cases in rural India), it won't glow. There are Reading Solar lights with LED (Best LED from a Company like Nichia corporation, Japan) which can be charged by sunlight or electric including USB. This lasts 8 hours. It costs around Rs 400(about 7 US$) in India. It consumes 0.2 Watts. Moreover by this light one can concentrate on the material reading (especially students) we used to have Reading lights in the past (Table Lights electric). In suggest Schools, NGOs, Government can promote these on a massive scale. Each Kwh saved is each Kwh generated. TODAYS WASTAGE IS TOMORROWS SHORTAGE. Please save the power for the next hour! Save power, energize the future.Dr.A.Jagadeesh Nellore(AP), India
