Your home theater equipment continues to consume energy even after you've turned it off. HDTVs, DVD/ Blu-ray players, receivers, subwoofers, and more go into sleep or stand-by mode when turned off, and continue to draw power when they're not in use. Monster GreenPower is a revolutionary new way to automatically eliminate energy waste and save money. Simply plug your HDTV or AV receiver into the Monster GreenPower Control outlet. When it's turned off or goes to sleep, the Monster GreenPower outlets switch off, automatically eliminating energy wasted by other components, when you're not using them. When your HDTV or AV receiver switches back on, the GreenPower outlets automatically power up again. The HDP 1850G also has two GreenPower RF Remote Controlled outlets that can easily be turned off with an included remote control, giving you another way to reduce stand-by mode energy waste.
