Stored energy is created whenever a particle has been moved through a field it interacts with ( requiring a force to do so ), but the energy to accomplish this is stored as a new position of the particles in the field — a configuration that must be " held " or fixed by a different type of force ( otherwise, the new configuration would resolve itself by the field pushing or pulling the particle back toward its previous position ).

Stored energy also affects his physical form-increasing his size, mass, and power, and granting him an indefinite lifespan.

Stored solar thermal energy has the potential to provide cheaper peak-demand power than any other energy source.

For years laserprinters have been the popular choice, however line matrix printers have improved technological aspects and now claim to hold significant benefits over laser printers in terms of energy savings, cost per page, reliability in industrial environments and media flexibility ( multipart forms, oversize media, peel off labels, cloth, or card stock ).

Several lines of printers, such as the Printronix P7000 cartridge series of line matrix printers are ENERGY STAR ® qualified and provide 40 percent operational energy savings compared to laser printers.

In this category one might include the laser printers, barcode readers, image scanning, illuminators, designators, optical data recording, combustion ignition, laser surgery, industrial sorting, industrial machining, and directed energy weaponry.

The label addresses safety issues such as " emissions, ergonomics, ecology, and energy " for computers, monitors and printers, as well as cell phones and furniture.
