Lack of planning has resulted in the congestion of cities causing extremely low energy efficiencies in urban transport.
The opportunities for conservation differ per means of transport. In case of passenger cars more energy can be conserved by improving the performance of these cars. The possibility of fuel conservation potential has been projected in Table Physical distances and choice of mode of transport determine energy essay energy conservation. The location of facilities in a city for housing, working, shopping, entertainment, etc.
has great effects on energy use. Decrease of traffic congestion by planning of traffic lights, one — way traffic, limited parking, etc. can reduce energy consumption. Transport by ship is very efficient as compared to surface transport and can be an important energy conservation measure. Railways are capital-intensive but considerably more energy efficient than roadways. It is important to rehabilitate, maintain and upgrade railways.
Promotion of use of bicycles is possible through public education, good and cheap bicycles availability. The animal cart design should be improved. Preventive maintenance, tuning of ignition and carburetor, essay energy conservation tyre pressure, etc.
can reduce fuel consumption, essay energy conservation. The commercial vehicles should run on diesel rather than gasoline. The energy efficiency can be improved through optimum routes, less trip frequency, essay energy conservation, location and distribution of freight distribution centres. Essay 3. Energy Conservation in Rural Areas: The major energy consumption in villages is by households followed by agriculture and cottage industries.
The main energy consuming activities are given in Table The main energy sources are wood, dung and agricultural residues. The energy balance of a village Pura in India is given in Table The use of commercial fuels is very low due to high cost and non-availability.
Therefore, conservation of cooking energy is very important. The other areas of interest are lighting, space heating and cottage industries. The oxygen supply for hearths should be controlled. The size and shape of wood logs, essay energy conservation, briquetting of agricultural residues and moisture content of fuels influence the combustion efficiency.
Depending upon the essay energy conservation of food, the method of cooking has influence on energy requirements. The food can be boiled, fried, stewed or baked. Use of pressure cooker can save the energy three fold. Similarly use of pots and pans of high thermal mass and conductivity will save energy. The land should be suitably divided for agriculture, animal grazing and fuel production depending upon the energy requirements.
The use of seeds, fertilizers, water and pesticides should be reduced by better timing as per soil conditions and type of crop. The efficiency of draught animals should be improved by crossbreeding and better feeding. Replacement of tractors by draught animals can save energy. Reduction in requirement of transport, storage, processing of food by optimization can save considerable energy. Energy can be saved through use of alternative techniques of drying, presetting before cooking, recycling of packing material.
Energy requirements for brick making and charcoal production can be reduced by use of modern steel kilns. Simple improvements of tools and implements used for making of handicrafts can save energy and work.
Essay 4. Energy Conservation in Urban Ares: Urban energy includes hot water, cooking, lighting, essay energy conservation, space conditioning and electrical appliances. Use of electricity and LPG with higher essay energy conservation of cooking ranges and hot plates essay energy conservation save energy.
The largest savings are possible in restaurants, hospitals and school hostels where large scale cooking is employed. Hot water is less of a basic need than cooking. If hot water is used only in winter, integration with space heating becomes rational. In poor households same fire is used for cooking and water heating. Fluorescent lights in place of essay energy conservation lights should be used where possible. In large buildings, optimal use of day light, changes in working hours and cogeneration of heat and electricity can result in large energy savings.
Space conditioning including cooling, heating, ventilation and air purification plays an important role in middle and high income group households. The energy consumption for air-conditioning may be ten times that for lighting. Cleaning and maintenance of air-conditioners can save large energy quantities. Large amounts of energy can be saved by controlling the product specifications, quality, taxes and education at Government essay energy conservation. The water temperature must be adjusted as per its use.
Leaking of pipes and taps of hot water should be avoided. In large buildings, cogeneration of heat and electricity and recycling of waste heat from air-conditioning and space heating plants should be used for water heating, essay energy conservation. Properly located and sized windows and cleaning of glass panes can reduce need for electrical lighting. Electric lights are more efficient than kerosene lamps, however electrification leads to use of more lights.
Proper design and construction of buildings and use of vegetation have favourable climatic effects. Proper setting and control of temperatures in air-conditioning and space heating equipment save energy. Insulation of buildings can reduce heat losses in cold countries and inlet of heat in warm countries. Washing of clothes at lower temperature, use of less detergent, proper food preservation outside refrigerator can save energy.
