Located on North Union Street in Alexandria , Virginia , the building is anchored to the edge of the Potomac , taking full advantage of the endless source of energy that the river provides . When a free-ranging electron is accelerated by the electric field of a proton or charged atom ( ion ) , the photons emitted can have a wide range of energies that depends on how fast the electrons are moving and how much they are accelerated . Energy intensity is not a perfect indicator of differences in energy efficiency , because it includes such differences as climate and population density , but it 's not a bad one , and it 's the best that there is to give you a single picture of the efficiency of energy use , how much economic production you get out of every dollar that you spend - - every unit of energy that you must consume , and the economic woes in Hungary and Poland are very tightly bound to their energy waste loss . Extending hope and opportunity depends on a stable supply of energy that keeps America 's economy running and America 's environment clean . Which involves chucking around the kinds of energies that could vaporize the entire atmosphere off the planet , with enough left lying around to rip the crust into tiny pieces , smash the moon into us and quite possibly Mars for an impressive Mortal Kombat style finishing move . " This impossibility is " explained " in the abstract thus : " Magnetic energy is taken directly ex vacua and used to replenish the permanent magnets of the MEG device , which therefore produces a source of energy that , in theory , can be replenished indefinitely from the vacuum . An employer participates in a program approved by the Oregon Department of Energy that reduces vehicle miles traveled through one-on-one contact with participants in a specific geographical area or in a targeted group . But much to their dismay , physicists found the electron had a wide range of energies that could not be explained if the electron was the only particle emitted .
