Power vampires
Specialists of Laboratory of Laurence in Berkeley prepared the research devoted to "vampire energy" in 2011 — so in the American power industry call electricity consumed by household appliances in a stanby mode. By estimates of scientists, on average the house there can be about 40 such devices which "eat" from 5 to 10% of the general consumed energy.
Authors of a research made the list of main house "vampires" which looks as follows: the desktop computer (7 dollars/month), the video game console (6 dollars), plasma or the LCD TV (5 dollars), the receiver of cable or satellite television with a digital recorder (3 dollars), an independent digital video recorder (3 dollars), the notebook (1.5 dollars), a DVD player (1 dollars). Everything together these devices annually absorb electricity for the amount from 100 to 160 dollars.
For economy researchers recommend to transfer computers to the energy saving modes, to buy LCD panels with smaller diagonal and to reduce their brightness and contrast and also to purchase the extenders which are automatically powering off on some sockets when falling consumption level below threshold.
