- Company Profile:
A general term for the visible and near visible (ultraviolet and near-infrared) electromagnetic radiation that is emitted by the sun. It has a spectral, or wavelength, distribution that corresponds to different energy levels; short wavelength radiation has a higher energy than long-wavelength radiation.
Industry:Energy
The storage of natural gas in underground reservoirs at a different location from which it was produced.
Industry:Energy
A provision to allow the conditional purchase or sale of a specific quantity of material in addition to the firm quantity in the contract.
Industry:Energy
Self-propelled vehicle that runs on rails and is used for moving railroad cars.
Industry:Energy
The total distribution of electromagnetic radiation emanating from the sun. The different regions of the solar spectrum are described by their wavelength range. The visible region extends from about 390 to 780 nanometers (a nanometer is one billionth of one meter). About 99 percent of solar radiation is contained in a wavelength region from 300 nm (ultraviolet) to 3,000 nm(near-infrared). The combined radiation in the wavelength region from280 nm to 4,000 nm is called the broadband, or total, solar radiation.
Industry:Energy
Gas from extraneous sources put into underground storage reservoirs.
Industry:Energy
A ruling issued by a utility commission granting or denying an application in whole or in part. The order explains the basis for the decision, noting any dispute with the factual assertions of the applicant. Also applied to a final regulation of a utility commission.
Industry:Energy
Sales to railroads for any use, including that used for heating buildings operated by railroads.
Industry:Energy
A device designed to receive solar radiation and convert it to thermal energy. Normally, a solar thermal collector includes a frame, glazing, and an absorber, together with appropriate insulation. The heat collected by the solar collector may be used immediately or stored for later use. Solar collectors are used for space heating; domestic hot water heating; and heating swimming pools, hot tubs, or spas.
