Energy Conservation, Essay Sample
Essay 1. Introduction to Energy Conservation: Energy conservation refers to the methods of reduction in energy consumption by way of elimination of wastage and promotion of efficiency. We know that due to the vast gap between demand and supply, lot of efforts is being done to bridge the gap in terms of generation of more electricity which requires lot of capital investment and apart from it creates lot of environmental concerns.
Energy conservation is the key element of energy management. We can reduce the energy consumption by adopting various ways of energy conservation which includes efficient use of technologies and avoiding energy wastages. Essay 2. This is in addition to the energy wasted by running equipment for longer than necessary. Electricity is the most expensive form of energy available — about 8 times the cost of coal and six times the cost of gas — this expensive fuel conservation of energy essay be used wisely.
No organization, whatever its size, can afford to overlook the improvement in profit and competitive position which can be achieved from the careful and thorough application of energy saving initiatives.
When investment opportunities are being assessed and compared by management, energy saving initiatives are too often given a much lower priority than production and development projects. This is despite the fact that energy saving initiatives can reduce revenue expenditure over the whole organization with very low capital investment requirements and can continue to do so over a very long period. Among the reasons given for this has been shortage of capital to invest and short-term company policies and it has been difficult for energy managers to gain the necessary support for energy saving projects.
Identification of energy saving opportunities must be carried out in a systematic manner so that it can be shown that the initiatives proposed are those which will yield the greatest benefits. Major opportunities will arise during the planning of new buildings and plant where the incremental cost of high efficiency equipment will be easy to determine, the lifetime will be longest and there will be no or little, difference in installation costs.
There will be many instances where the installation of more modern equipment will be so beneficial that the replacement of existing equipment before its normal end-of-life will be justified by savings on running costs. Experience gained by monitoring the performance of conservation of energy essay plant and comparing with it older plant will provide useful data.
Careful and systematic monitoring will be required to identify energy saving opportunities. It is essential that the energy demands and costs of every aspect of the business are well understood, so that areas of greatest waste can be identified and tackled and that solutions for one situation can be applied to similar areas. Full records should be maintained so that cost savings can be demonstrated and so that previously identified opportunities can be re-visited as costs and engineering solutions change.
An organised approach will help to show management that the best investments are being selected for further work. Business usually give lower priority to cost reduction from energy savings than they do other business initiatives, conservation of energy essay. Business expansion is usually given higher priority, but conservation of energy essay capital for this has to be provided from the profit from the existing business. Energy saving initiatives reduces operating costs and therefore increase the revenue available for investment and so deserve a very high priority.
Electricity is by far the most expensive form in which an organization buys power. The fact that electricity is the only practical form of energy does not mean that it should be used without proper consideration. While thermal savings are keenly monitored and can readily be measured, much less attention has been paid conservation of energy essay the money that can be saved by attention to the design, specification and installation of electrical plant and power systems.
The efficiency of electrical equipment has always been assumed to be high and the amount of electrical energy that is wasted in commercial and industrial environments is usually greatly underestimated and is often assumed conservation of energy essay be unavoidable, conservation of energy essay.
In fact, the efficiency of electrical equipment can be improved easily at low cost and because of the quantity of electrical energy used, this will yield substantial savings. Once high-efficiency equipment has been selected, it is equally important to ensure that it is correctly rated. On the other hand, cables are least conservation of energy essay when fully loaded, so generous rating of cables can substantially reduce running costs, conservation of energy essay.
Power losses in electrical equipment are due to the electrical resistance in conductors and losses in the magnetic material and occur primarily in motors, transformers and in all cabling. The conductor losses are proportional to the resistance and the square of the current I 2 R losses and can be minimized by using the optimum size of conductor for the application.
Magnetic losses can be reduced by the use of better materials and production methods. The available savings in energy costs are substantial and accrue over the whole conservation of energy essay the life of the installation.
Electrical energy is undisputedly the most vital element for industrial growth of any country. India is one of the many developing countries, which is suffering from acute power shortages. Almost all the states of India are not able to manage the demand from the three main sectors, viz. The recent industrial growth due to economic reforms further worsened the situation. This results in exhaustion of fossil fuels and causes conservation of energy essay imbalance.
Therefore, conservation of energy essay, conservation of energy essay is an ample opportunity of energy conservation in domestic, industrial and agriculture sector. Essay 3. Energy Conservation conservation of energy essay Domestic Sector: There is a wide gap in the supply and demand of power in India and bridging the gap by installing new power stations is not going to take place in near future.
The other alternative is to conserve every watt of energy. Previously the power was subsidized in all the states of India and people mis used power liberally without worrying about efficiency of the appliances. Because of the economic reforms, the subsidy is being withdrawn in power sector in a phased manner throughout India and the power tariff is steadly increasing and the people began to realize the need for energy conservation.
Even the Government of India made an act for energy conservation inwhich shows the seriousness of the power situation. Since domestic sector use the power in variety of applications, this is a potential area to be considered for energy optimization.
By reducing the domestic energy consumption, the other sectors will get more power thereby helping the country to prosper further. Energy used at home comprises of energy for cooking and processing food, comforts and luxuries. While an urban home largely depends on cooking gas and electricity for its energy requirements. Most of the energy demand of a rural home is dependent on fire wood or fuel wood. The domestic energy expenditure, with the conservation of energy essay cost conservation of energy essay energy, is gradually assuming a sizable share of the total domestic expenditure.
The per capita electricity consumption in the country is reported to be about units per annum with Gujarat on the top with an average of about units. The average cost of one unit of electricity in the country is in the range of Rs. Cheap and sub-standard gadgets consume more energy as compared to expensive standard gadgets and prove to be costlier on a long run.
Energy consumption in Indian domestic sector mostly comprises of electricity used in homes for lighting, refrigeration and power supply for other gadgets, conservation of energy essay. Other forms of energy used are fuel for cooking etc. So there is an angle opportunity of energy conservation in electrical energy used in domestic sector in India.
So, electrical energy saving potential lies in lighting luminaires, refrigeration equipment and gadgets. Lot of energy can be saved by adopting latest technology in these equipment, conservation of energy essay. As we know that electric lighting burns considerable amount of the average home energy budget. The electricity used over the lifetime conservation of energy essay a single incandescent bulb costs 5 to 10 times the original purchase price of the bulb itself.
Compact Fluorescent Lights CFL and Light Emitting Diode LED bulbs have revolutionized energy-efficient lighting. CFLs are simply miniature versions of full-sized fluorescents. They screw into standard lamp sockets and give off light that looks just like the common incandescent bulbs — not like the fluorescent lighting we associate with factories and schools. LEDs are small, solid light bulbs which are extremely energy-efficient. New LED bulbs are conservation of energy essay in clusters with diffuser lenses which have broadened the applications for LED use in the home.
Lot of electrical energy can be saved in the domestic sector by adopting the suitable energy conservation techniques in the following equipment used in household:. Despite their inefficiency, they are still preferred in lower income groups just because of their very low initial cost.
Fluorescent lamps are also popular and are used mainly in the utility areas like reading rooms, bedrooms and living rooms, though they are costlier by more than 10 to 15 times than incandescent lamps. Even in the fluorescent lamps, aluminium chokes are predominant, which cost much less compared to copper choke. Hence it is one area that should be concentrated most for conservation of energy. Now-a-days use of CFLs Compact Fluorescent Lamp is steadily increasing because of their very low power consumption, long life and better illumination over incandescent lamps.
However, CFLs may not be a replacement when illumination is required for precision work. Table 3. From table one can observe that the incandescent lamp is a source for energy wastage because of its low luminous efficiency. Following calculation shows how economic to replace incandescent with fluorescent Tube Light FTL and with CFL, conservation of energy essay.
For calculations it is assumed that the operation hours are 5 hours per day and the cost of energy as Rs. In both the cases, conservation of energy essay, it can be observed that the savings are very impressive and hence replacement of incandescent lamps is highly recommended.
The payback period is inversely proportional to the period of usage, conservation of energy essay. Another method to conserve energy in this area is to use the natural light effectively so that the period of usage of lamps may be minimized.
Apart from it, energy efficient LED lamps can also be used in place of incandescent lamps. Fans, once a luxury, conservation of energy essay, became essential now for Indian climatic conditions where temperatures rise to as high as 45°C in summer. In India, fans available at varying cost ranging from as low as Rs.
Cheap fans normally use substandard core laminations and aluminium windings. Standard fans are made with quality material but cost two to three times. The power consumption varies from 60 Watts to 90 Watts depending on the quality of the fan, conservation of energy essay. Though electronic regulators are available in the market at costs ranging from Rs.
The user has no choice for opting for an electronic regulator. At medium speeds, a saving of about 14 Watts was observed with the use of electronic regulator. Replacement of low efficient fan with series regulator with high efficient fan with electronic regulator is highly recommended. Following is a comparison of economics of a High Cost Fan HCF and Low Cost Fan LCFat a nominal 8 hours a day.
Refrigerator is another common appliance in middle and upper classes in India. These are available in variety of capacities and models, but the most popular among them is the single door liters capacity. Almost all the refrigerators have right hinged doors operated with right hand. Operation of the refrigerator with right hand takes longer time since door opening and handing the contents is to be done by right hand only.
This conservation of energy essay particularly true with cooking items since they are normally touched with right hand only in India. This leads to loss of cooling and can be saved to some extent if a left hinged door is provided. Refrigerators in India are mostly used for preservation of food items and for cold water.
