Today’s state of the art moochers sucking the energy out of your house wiring, instead of blood from your veins, are known as "Energy Vampires". Electronics that are powered by remotes/off buttons, but have an external light glowing actually are in standby mode….continuously using power. Items with external displays, such as clocks, that stay glowing while powered down is another devourer of electricity.
Some of the most common power hungry devices are TVs, DVR or satellite boxes, video game consoles, desktop computers (in sleep mode), and laptops (plugged-in).
