Dablink For a similar but not so broad sense, see Power engineering . Energyengineering is a broad field of engineering dealing with efficient energy use energy efficiency , energy services , facility management , plant engineering , environmental compliance and alternative energy technologies. Domain of EnergyEngineering expertise combines selective subjects from the fields Chemical, Mechanical and Electrical Engineering. It is an interdisciplinary program which has relativity with electrical, mechanical and chemical engineeringEnergy minimization is the purpose of this growing discipline. Often applied to building design, heavy consideration is given to HVAC , lighting, refrigeration, to both reduce energy loads and increase efficiency of current systems. EnergyEngineering is increasingly seen as a major step forward in meeting carbon reduction targets. Energy Technology refers to the knowledge of and usage skills required for conversion, production, transfer, distribution and use of energy. This leads to the mastering of technology based on the laws of nature, as a result of which different forms of energy can be used to serve the needs of mankind in such a way that nature is spared and the economic resources of society are taken into consideration. Energy and its relation to the environment is a new and rapidly growing field of sustainability .

The optical optics term encircled energy refers to a measure of concentration of energy in an optical image , or projected laser beam laser at a given range. If a single star is brought to its sharpest Focus optics focus by a lens optics lens giving the smallest image possible with that given lens called a point spread function or PSF , calculation of the encircled energy of the resulting image gives the distribution of energy in that PSF. Encircled energy is calculated by first determining the total energy of the PSF over the full image plane, then determining the centroid of the PSF. Circles of increasing radius are then created at that centroid and the PSF energy within each circle is calculated and divided by the total energy. As the circle increases in radius, more of the PSF energy is enclosed, until the circle is sufficiently large to completely contain all the PSF energy. The encircled energy curve thus ranges from zero to one. A typical criterion for encircled energy EE is the radius of the PSF at which either 50 or 80 of the energy is encircled. This is a linear dimension, typically in micrometre micrometer s. When divided by the lens or mirror focal length, this gives the angular size of the PSF, typically expressed in Minute of arc arc seconds when specifying astronomical optical system performance. Encircled energy is also used to quantify the spreading of a laser beam ... energy is divided by the projection distance to give the angular spreading.

Beyond simply identifying the sources of energy use, an energy audit seeks to prioritize the energy uses according to the greatest to least cost effective opportunities for energy savings. Home energy audit A home energy audit is a service where the energy efficiency ... red cameras , with the aim to suggest the best ways to improve energy efficiency in heating and cooling the house. An energy audit of a home may involve recording various characteristics of the building ... the efficient energy use efficiency , physical condition, and programming of HVAC mechanical systems such as the heating, ventilation, air conditioning equipment, and thermostat. A home energy audit may include a written report estimating energy use given local climate zone climate criteria, thermostat settings, roof overhang, and sun path solar orientation . This could show energy use for a given time period, say a year, and the impact of any suggested improvements per year. The accuracy of energy ... of electricity, natural gas, fuel oil, or other energy sources consumed over a one or two year period. Some of the greatest effects on energy use are user behavior, climate, and age of the home. An energy audit may therefore include an interview of the homeowners to understand their patterns of use over time. The energy billing history from the local utility company can be calibrated using ... with the thermal energy model of the building. Advances in computer based thermal modeling can take into account many variables affecting energy use. A home energy audit is often used to identify ... more details

This force ... of stretching the spring or lifting the mass requires energy to perform. The energy that went into lifting up the mass is stored in its position in the gravitational field , while similarly, the energy it took to stretch the spring is stored in the metal. According to the law of conservation of energy , energy cannot be created or destroyed hence this energy cannot disappear. Instead, it is stored as potential energy. If the spring is released or the mass is dropped, this stored energy will be converted into kinetic energy by the restoring force , which is Elasticity physics elasticity in the case ... climbs a hill it has potential energy. At the very top of the hill is its maximum potential energy. When the car speeds down the hill potential energy turns into kinetic. Kinetic energy is greatest at the bottom. The more formal definition is that potential energy is the energy difference between the energy of an object in a given position and its energy at a reference position. There are various types of potential energy, each associated with a particular type of force . More specifically, every conservative force gives rise to potential energy. For example, the work of an Elasticity physics ... more details

Internal energy has two major components, kinetic energy and potential energy . The kinetic energy is due ... vibrations , and the potential energy is associated with the static constituents of matter, electricity static electric energy of atom s within molecules or crystal s, and the static energy of chemical bond s. The internal energy of a system can be changed by heating the system or by doing Work thermodynamics ... energy is equal to the total heat added and work done. If the system is isolated, its internal energy cannot change. For practical considerations in thermodynamics or engineering it is rarely necessary, nor convenient, to consider all energies belonging to the total intrinsic energy of a sample system, such as the energy given by the equivalence of mass. Typically, descriptions only include ... of the internal energy. The internal energy is a state function of a system , because its value ... at this state. It is an extensive quantity . The SI unit of energy is the joule J . Sometimes a corresponding ... energy is defined, which is internal energy per a unit of mass of the system in question. As such, the SI unit of specific internal energy is joules kilogram J kg . If intensive internal energy is expressed on a per Mole unit mole basis, then it is referred to as molar internal energy and the unit is joule mole J mol . From the standpoint of statistical mechanics , the internal energy is equal to the ensemble average of the total energy of the system. It is also called intrinsic energy. Description ... more details
