- Company Profile:
Electromagnetic energy transmitted from the sun (solar radiation). The amount that reaches the earth is equal to one billionth of total solar energy generated, or the equivalent of about 420 trillion kilowatt-hours.
Industry:Energy
A chemical element, of atomic number 14, that is semi-metallic, and an excellent semiconductor material used in solar photovoltaic devices; commonly found in sand.
Industry:Energy
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
Any fuel that is in solid form, such as wood, peat, lignite, coal, and manufactured fuels such as pulverized coal, coke, charcoal, briquettes, pellets, etc.
Industry:Energy
Water in vapor form; used as the working fluid in steam turbines and heating systems.
Industry:Energy
A device that converts high-pressure steam, produced in a boiler, into mechanical energy that can then be used to produce electricity by forcing blades in a cylinder to rotate and turn a generator shaft.
Industry:Energy
A type of motor designed to operate precisely at the synchronous speed with no slip in the full-load speeds (rpm).
Industry:Energy
An electrical generator that runs at a constant speed and draws its excitation from a power source external or independent of the load or transmission network it is supplying.
Industry:Energy
A device used to control temperatures; used to control the operation of heating and cooling devices by turning the device on or off when a specified temperature is reached.
Industry:Energy
A device for converting the flow of a fluid (air, steam, water, or hot gases) into mechanical motion.
