The energy required for delivery and treatment of fresh water often constitutes a significant percentage of a region's electricity and natural gas usage (an estimated 20 of California's total energy use is water-related. 6 ) In light of this, some local governments have worked toward a more integrated approach to energy and water conservation efforts. Unlike the other sectors, total energy use in the industrial sector has declined in the last decade. While this is partly due to conservation efforts, it's also a reflection of the growing trend for. Companies to move manufacturing operations offshore. The usage of telecommuting by major corporations is a significant opportunity to conserve energy, as many Americans now work in service jobs that enable them to work from home instead of commuting to work each day.

5 Lighting is also generally the most wasteful component of commercial use. A number of case studies indicate that more efficient lighting and elimination of over-illumination can reduce lighting energy by approximately fifty percent in many commercial buildings. Commercial buildings operations can greatly increase energy efficiency by thoughtful design, with today's building stock being very poor examples of the potential of systematic (not expensive) energy efficient design (Steffy, 1997). Commercial buildings often have professional management, allowing centralized control and coordination of energy conservation efforts. Solar heat loading through standard window designs usually leads to high demand for air conditioning in summer months. An example of building design overcoming this excessive heat loading is the dakin building in Brisbane, california, where fenestration was designed to achieve an angle with respect to sun incidence to allow maximum reflection of solar heat; this design also assisted in reducing interior over-illumination. Industrial sector change change source the industrial sector represents all production and processing of goods, including manufacturing, construction, farming, water management and mining. Increasing costs have forced energy -intensive industries to make substantial efficiency improvements in the past 30 years. For example, the energy used to produce steel and paper products has been cut 40 in that time frame, while petroleum/aluminum refining and cement production have reduced their usage by about. These reductions are largely the result of recycling waste material and the use of cogeneration equipment for electricity and heating.

However, Ground source heat Pump systems are the more energy efficient, environmentally clean, and cost-effective space conditioning systems available (Environmental Protection Agency and can achieve reductions in energy consumptions of up. Best building practices change change source current best practices in building design long and construction result in homes that are much more energy conserving than average new homes. See passive house, superinsulation, self-sufficient homes, zero_ energy _building, earthship, straw-bale construction, mit design Advisor, energy conservation Code for Indian Commercial buildings. Smart ways to construct homes such that minimal resources are used to cooling and heating the house in summer and winter respectively can significantly reduce energy costs! Commercial sector change change source the commercial sector consists of retail stores, offices (business and government restaurants, schools and other workplaces. Energy in this sector has the same basic end uses as the residential sector, in slightly different proportions. Space conditioning is again the single biggest consumption area, but it represents only about 30 of the energy use of commercial buildings. Lighting, at 25, plays a much larger role than it does in the residential sector.

Despite technological improvements, many American lifestyle changes have put higher demands on heating and cooling resources. The average size of homes built in the United States has increased significantly, from 15 to 23The single-person household has become more common, as has central air conditioning: 23 of households had central air conditioning in 1978, that figure rose to 55 by 2001. As a cheaper alternative to the purchase of a new furnace or air conditioner, most public utilities encourage smaller changes the consumer can make to lessen space conditioning usage. Consumers have also been asked to adopt a wider indoor temperature range (e.g. 65 f in the winter, legs 80 f in the summer). Home energy consumption averages: 4 change change source space conditioning, 44 water heating, 13 lighting, 12 refrigeration, 8 home electronics, 6 laundry appliances, 5 kitchen appliances, 4 other uses, 8 Energy usage in some homes may vary widely from these averages. In most residences no single appliance dominates, and any conservation efforts must be directed to numerous areas in order to achieve substantial energy savings.

A car or truck moving at 55 miles an hour can get about 15 percent better fuel economy than the same car going 65 mph. According to the. Department of Energy (doe as a rule of thumb, each 5 mph you drive over 60 mph is similar to paying an additional.20 per gallon for gas (at.10 per gallon). 3 Residential sector change change source the residential sector refers to all private residences, including single-family homes, apartments, manufactured homes and dormitories. Energy use in this sector varies significantly across the country, due to regional climate differences and different regulation. On average, about half of the energy used in the. Homes is expended on space conditioning (i.e. The efficiency of furnaces and air conditioners has increased steadily since the energy crises of the 1970s. The 1987 National Appliance Energy conservation Act authorized the department of Energy to set minimum efficiency standards for space conditioning equipment and other appliances each year, based on what is "technologically feasible and economically justified".

The next decade saw dramatic improvements in fuel economy, mostly the result of reductions in vehicle size and weight. These gains eroded somewhat after 1990 due to the growing popularity of sport utility vehicles, pickup trucks and minivans, which fall under the more lenient "light truck" cafe standard. In addition to the cafe program, the. Government has tried to encourage better vehicle efficiency through tax policy. Since 2002, taxpayers have been eligible for income tax credits for gas/electric hybrid vehicles. A "gas-guzzler" tax has been assessed on manufacturers since 1978 for cars with exceptionally poor fuel economy. While this tax remains in effect, it currently generates very little revenue as overall fuel economy has improved.

Another focus in gasoline conservation is reducing the number of miles driven. An estimated 40 of American automobile use is associated with daily commuting. Many urban areas offer subsidized public transportation to reduce commuting traffic, and encourage carpooling by providing designated high-occupancy vehicle lanes and lower tolls for cars with multiple riders. In recent years telecommuting has also become a viable alternative to commuting for some jobs, but as of 2003 only.5 of workers were telecommuters. Ironically, hundreds of thousands of American and European workers have been replaced by workers in Asia who telecommute from thousands of miles away. A vehicle's gas mileage normally decreases rapidly at opinion speeds above 55 miles per hour.

Energy Flow Trends - 2002 Contents Energy efficiency trends in the United States change change source the. Is currently the largest consumer of energy, although at current levels of growth, it is possible that in the future China could become the leading energy consumer. Department of Energy categorizes national energy use in four broad sectors: transportation, residential, commercial, and industrial. 1 Energy usage in the transportation and residential sectors (about half. Energy consumption) is largely controlled by individual domestic consumers.

Commercial and industrial energy usage are controlled by businesses. National energy policy has a significant effect on energy usage across all four sectors. Transportation sector change change source the transportation sector includes all vehicles used for personal or freight transportation. Of the energy used in this sector, approximately 65 is consumed by gasoline -powered vehicles, primarily personally owned. Diesel -powered transport (trains, merchant ships, heavy trucks, etc.) consumes about 21, and air traffic consumes most of the remaining. 2 The oil supply crises of the 1970s spurred the creation, in 1975, of the federal Corporate average fuel Economy (cafe) program, which required auto manufacturers to meet progressively higher fleet fuel economy targets.

Individuals and book organizations that are direct consumers of energy may want to conserve energy in order to reduce energy costs and promote economic, political and environmental sustainability. Industrial and commercial users may want to increase efficiency and thus maximize profit. On a larger scale, energy conservation is an important element of energy policy. In general, energy conservation reduces the energy consumption and energy demand per capita. This reduces the rise in energy costs, and can reduce the need for new power plants, and energy imports. The reduced energy demand can provide more flexibility in choosing the most preferred methods of energy production. By reducing emissions, energy conservation is an important method to prevent climate change. Energy conservation makes it easier to replace non-renewable resources with renewable energy. Energy conservation is often the most economical solution to energy shortages.

Energy conservation is a process used to reduce the quantity of energy that is used for different purposes. This practice may result in increase of financial capital, environmental value, national and personal security, and human comfort.

There is a need to resort to energy management. This concept recognizes that no single energy source can possibly provide all the energy required by the source nation. Thus, the basic objective of the integrated energy management is to obtain sustainable energy and which should be realized at the local level. In addition, measures to conserve energy need to be followed. Energy conservation is considered as a quick and economical way to solve the problem of power shortage as also a means of conserving the countrys finite sources of energy. Energy conservation measures are cost effective, require relatively small investments and have short gestation as well as pay back periods. The studies conducted by Energy management Centre, new Delhi have indicated that there is about 25 potential of energy conservation in the industrial sector).

Fossil fuel resources took millions of years to form and are infinite. These resources may be exhausted in a few hundred with years. Historical evidence shows that world energy demand has increased at almost the same rate as gross world product (GWP). People living in industrialized or developed countries are a relatively small percentage of the worlds total population, but they consume a huge share of the total energy produced in the world. The main issues regarding the energy problem in urban areas are: (a) How to utilize the energy from non-renewable sources at their maximum efficiency. Advertisements: (b) How to make use of renewable sources of energy or the alternative energy sources? Energy policy today has two choices (paths). One path leads to the fossil fuels (hard path which means continuing as we have been for a number of years. E., emphasising energy quantity by finding more amount of fossil fuels and building much larger power plants.
