    Energy management as a critical boardroom issue is not overstating the case. This remains true despite the easing of the situation in California. Energy prices are, by their very nature, highly volatile, and ongoing deregulation may begin to expose companies to that volatility. In addition, energy can, and does, have a significant impact on business's financial well being, far beyond its mere cost. For example, a brief power outage caused a South Carolina-based polyester manufacturing facility to shut down for repairs for an extended period of time. During the shutdown, the company lost more than 80 million pounds of production, or about 8% of the site's annual output. The damage was more than material: company officials estimate that lower sales volumes and property damages from the outage will reduce earnings by $12.5 million, or 25 cents a share

    Until that day, it is likely that few in the company considered the deep impact that energy could have on their business. Without a dependable energy flow, business grinds to a halt. Employees can't work. Companies lose critical production time. And profits turn into losses. Energy management, in a new, more strategic definition, would include selecting alternative and redundant energy sources where appropriate, and might have helped avert or at least mitigate such a disaster.

    This redefinition of energy management as part of overall business strategy has already taken hold at companies across the country. For example, a metal processing company on the West Coast made more than $150 million by scaling back production and selling the resulting unused electricity on the wholesale market. The company didn't have generating capacity of its own, but rather had a contract with its electric supplier that allowed it to sell unused demand on the wholesale market. Someone at the company redefined energy management when they saw that price spikes in electricity on wholesale markets meant that the company could make more reselling electricity than it could processing metal-its core business

    What are the properties of energy?


    Energy can be transferred from one object or system to another through the interaction of forces between the objects


    Energy comes in multiple forms: kinetic, potential, thermal (heat), chemical, electromagnetic, and nuclear energy.

    In principle, energy can be converted from any one of these forms into any other, and vice versa, limited in practice only by the Second Law of Thermodynamics

    Energy is always conserved, that is, it is never created anew or destroyed - this is called the First Law of Thermodynamics.

    Energy management
    The phrase energy management refers to The judicious and effective use of energy to maximize profits (minimize costs) and enhance competitive positions

    The primary objective of energy management is to maximize profits
    or minimize costs. Some desirable subobjectives of energy management
    programs include:
    1. Improving energy efficiency and reducing energy use, thereby reducing
    costs
    2. Cultivating good communications on energy matters
    3. Developing and maintaining effective monitoring, reporting, and
    management strategies for wise energy usage
    4. Finding new and better ways to increase returns from energy investments
    through research and development
    5. Developing interest in and dedication to the energy management
    program from all employees
    6. Reducing the impacts of curtailments, brownouts, or any interruption
    in energy supplies

    Considerable cost savings can be realised by applying energy efficiency principles to building design and the multitude of systems needed to sustain its various functions it supports. With regard to building design this could include optimum site orientation, insulation, energy efficient windows, temperature control, lighting and energy saving office equipment. At Antarctica stations substantial energy savings may result from implementing water conservation programs, waste energy recovery techniques, automated building management systems and personnel training on energy conservation.

    Energy and Energy Management became household words again in
    the new millennium, with frequent TV and newspaper stories on electrical
    brownouts, blackouts and price spikes. Natural gas hit the news with
    price spikes over $10 per million Btu.

    The field of
    energy management has always been a dynamic, fast-paced profession
    that has been driven by a combination of technological advances and
    energy and environmental initiatives from our federal and state governments.
    Rapid changes in technology and policy have created the need for
    quick response through both formal and organized education and individual
    self-education.

    years.
    This growth in energy management has brought many newcomers
    into our profession, seeking the same tools and techniques that have
    served us so well for many years. The basic driving function is the availability
    of new, energy efficient technologies for providing our standard
    energy services - light, heat, air conditioning, motors, and process equipment
    for commercial facilities, manufacturing shops and heavy industries. Electronic computers and controls have not only provided new
    technology, but the price for the new technologies is most often significantly
    less than the cost of the older technologies. Learning how to assess
    the applications of these new technologies and how to estimate their
    energy savings and energy cost savings are still the critical skills needed.

    many businesses and industries are adopting a Total Quality
    Management (TQM) strategy for improving their operations. Any TQM
    approach should include an energy management component to reduce
    energy costs.

    Example: With only 5 percent of the world’s population, the United States consumes about 25 percent of its energy and produces about 25 percent
    of the world’s gross national product (GNP). However, some
    nations such as Japan, West Germany, and Sweden produce the same
    or greater GNP per capita with significantly less energy than the
    United States.

    Problems:
    U.S. energy production:
    Domestic crude oil production peaked in 1970 at just over 10 million
    barrels per day (MBD), and has fallen slowly since then to just over 5.8
    MBD in 2000. Domestic gas production peaked in 1973 at just over 24
    trillion cubic feet (TCF) per year. Gas production remained fairly
    steady between 1988 and 1992 at about 21-22 TCF per year.
    Cost of imported oil:
    Annual average prices per barrel for imported crude oil rapidly escalated
    from $3.00 in the early 1970’s to $12 in 1973-1974 and to $37 in
    1981. Since 1981 prices have fallen from this peak, and dropped to
    about $12 in 1986. From 1986 to 1996, prices ranged from about $12 to
    $22 a barrel, with a short spike in prices during the 1989-90 Gulf War.
    Prices dropped to $10 in 1998, and have since risen back to about $26.
    Reliance on imported oil:
    The United States has been a net importer of oil since 1947. In 1970 the
    bill for this importation was only $3 billion; by 1978 it was $42 billion;
    by 1979, $60 billion; and by 1981, $80 billion, even though the volume
    imported was less than in 1979. This imported oil bill has severely
    damaged our trade balance and weakened the dollar in international
    markets. In 1985 the bill for oil imports fell to a low of $37 billion. It
    climbed to almost $64 billion in 1990. In 1996 it was just over $61
    billion, but with lower prices after 1996, it was just over $50 billion in
    1998. But, with higher prices in 2000, it was $119 billion.
    In addition to these discouraging statistics, there are a host of major
    environmental problems, as well as economic and industrial competitiveness
    problems, that came to the forefront of public concern in the late
    1980’s. Reducing energy use can help minimize these problems by:

    Limiting global climate change. Carbon dioxide, the main contributor
    to potential global climate change, is produced by the combustion of
    fossil fuel, primarily to provide transportation and energy services. In
    1992, many countries of the world adopted limitations on carbon
    dioxide emissions.

    Limiting ozone depletion. In the U.S., about half of the CFC’s—which
    have been associated with ozone depletion—are used in providing
    energy services through refrigeration and air conditioning, and in
    manufacturing insulation. Recent international agreements will substantially
    phase out the use of CFC’s in industrialized countries by the
    year 1996.

    Wind energy has technological “noise” and aesthetic problems that
    probably can be overcome, but it too is very expensive. In addition, it
    is only feasible in limited geographic regions.

    Alcohol production from agricultural products raises perplexing
    questions about using food products for energy when large parts of
    the world are starving. Newer processes for producing ethanol from
    wood waste are just being tested, and may offer some significant
    improvements in this limitation.

    I didn't rephrase the texts
    After you start, if you need me to proofread
    it for you or revise the grammar and structure
    of it, let me know

    regards
