The APC Back-UPS ES 750 saves energy by cutting off power to the peripherals when a computer is not in use.

Surge suppressors can save the world. Really, they can. Those mundane power strips we use for our computers and our home entertainment systems can help us stave off the effects of global warming.
How exactly? Do they suddenly have carbon dioxide and methane scrubbers in them? Can they sequester carbon within their tiny circuits? Can they recover your paycheck at the gas pump?
No, no and no. But surge suppressors can help us save energy—and lots of it.
That’s because generating electricity produces greenhouse gases. About 40 percent of greenhouse gases come from electrical power plants, many of which burn greenhouse-gas emitting coal to produce energy. That’s one bad thing. Another is that we waste anywhere from 5 to 15 percent of that electricity—depending on the country you’re in—by leaving our electronics in “standby” modes that draw power even when they’re turned off, but remain plugged in. That amounts to an estimated $4 billion in energy costs in the United States alone. And yes, many of our electronics continue to draw power when they’re turned “off.” This is called standby, phantom, or vampire power.
One of the best things you can do, then, is to unplug your precious gadgets when they’re not being used. Let’s face it, though: That’s inconvenient and in many cases, impractical. The next best thing? Plug ‘em into surge suppression strips that have switches, so when you’re done working on your computer or watching a movie, you can switch the whole strip off. All the electronics plugged into it cease drawing power, and they remain protected from electrical spikes. (Switching it off breaks the circuit.)
This is an inexpensive and simple way to save energy and money. The only problem: Most surge suppressors get tucked behind or under computer and entertainment consoles, remaining out of sight and out of reach. (Let’s face it, they aren’t convenient devices - check out my Surge Suppressor Peeve)
Surge suppressor manufacturers are seeing our desire for better energy efficiency, though, and several cool and practical solutions are already available.
Auto Off
APC’s Power-Saving SurgeArrest P7GT, for example, automatically shuts off up to three peripheral devices connected to your computer when it’s turned off or enters sleep or hibernation mode. Plug your computer into the “Master” control outlet and peripherals such as a printer, speakers and monitor in the “Controlled by Master” outlets. Simple relays shut off power to the three peripherals when the computer uses 15 watts or less, then open current to the peripherals when the computer draws 40 or more watts or turns on. This is a great product if you have kids who leave the computer or peripherals on after they’re done.
APC’s Back-UPS ES 750 uninterruptible power supply does the same, along with surge suppression. So if you want some battery backup and energy savings, this may be the way to go.
We expect to see many similar power products that automatically shut down connected peripherals and other devices. Also, look for APC to offer surge suppressors for home theater use.
APC’s new 350, 450, 550 and 650 Back-UPS models due in July also offer surge protection and battery backup, but not the automatic-off feature for peripherals. Like the 750, the units are compliant with the Restriction of Hazardous Substances (RoHS) directive, which prohibits the use of six hazardous materials in the manufacturing of electronics, including lead, mercury, cadmium, hexavalent chromium, PBB, and PBDE. As a final touch, the packaging for the new units is made from recycled material.
Remote Off
Belkin is taking a different tack with its Conserve surge suppressor, coming out in September. This guy offers a radio-frequency remote control to conveniently shut off six of the eight outlets on the strip. The other two outlets remain “hot” for devices you don’t want to shut off, like a cordless phone, cable modem or DVR.

Melody here again from Belkin. To answer your question: Generally speaking, today’s TVs and home theater components retain their memory settings when unplugged, which is effectively all Conserve surge protector is doing when the switch is pressed to eliminate standby. The use of inexpensive “non-volatile memory” allows electronics to keep their settings even when power is removed.

I’m the PR Manager at Belkin, and I want to answer your question as to whether shutting down your devices will reduce their life cycles.
Since eliminating standby with the Conserve surge protector takes place after most electronics have been powered down using normal means (their own remote, for example), Conserve will not unduly stress electronic devices. It’s important to note that unlike the automatic surge protectors, Conserve gives you more convenient control over how and when your devices are completely turned off, and it’s not intended to replace existing on/off switches. But in general, today’s solid state electronics are much less likely to experience that “thump” caused when they’re turned on, and they’re able to deal with many thousands of on/off cycles.
“Green”
How tedious.
Steven the ultra-lib needs to take a serious look at the performance of surge suppressors instead of ASSUMING that global warming even exists, let alone manmade.

Electricity plants do not produce 40% of greenhouse gases. Are you Al Gore just making stuff up? 99.996% of greenhouse gases are produced by mother nature herself through lightning storms (lightning also produces ozone, ooooooh), decomposition of biomatter, volcanic activity, forest fires, etc.
