Unreferenced stub auto yes date December 2009 In photometry optics photometry , luminous energy is the perceived energy of light . This is sometimes called the quantity of light . Luminous energy is not the same as radiant energy , the corresponding objective physical quantity . This is because the human eye can only see light in the visible spectrum and has different sensitivities to light of different wavelength s within the spectrum. When adapted for bright conditions photopic vision , the eye is most sensitive to light at a wavelength of 555 metre nm . Light with a given amount of radiant energy will have more luminous energy if the wavelength is 555 nm than if the wavelength is longer or shorter. Light whose wavelength is well outside the visible spectrum has a luminous energy of zero, regardless of the amount of radiant energy present. The SI unit of luminous energy is the lumen second , which is unofficially known as the Talbot unit Talbot in honor of William Henry Fox Talbot . In other systems of units , luminous energy may be expressed in basic units of energy.

Dablink For a similar but not so broad sense, see Power engineering . Energy engineering 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 Energy Engineering expertise combines selective subjects from the fields Chemical Engineering Chemical , Mechanical Engineering Mechanical and Electrical Engineering . It is an Interdisciplinarity interdisciplinary program which has relativity with electrical, mechanical and chemical engineering. Energy 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. Energy Engineering is increasingly seen as a major step forward in meeting Carbon neutrality carbon reduction targets . Energy Technology refers to the knowledge, skills, and equipment required for the production, conversion, transference, distribution, and utilization 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 Natural environment environment is a new and rapidly growing field of sustainability .
