Better Home Networking Could Save $330 Million




When an especially high electricity bill arrives in the mail, it's enough to just adjust the dials on the thermostat and the refrigerator, right? Maybe not.Usb Sticks Promo.com specializes in all usb related products such as branded usb sticks,promotional usb sticks,mini usb sticks and customed usb flash drives according to your needs,welcome! It turns out it's the tangle of electronics near the television that's the fastest growing segment of energy use.

Most of the electronics,We are leading pcb manufacturer and factory offering Buy Metal Core PCB Online wholesale,you can buy Double layers pcb products on our website. including laptops, smart phones and tablets, require an Internet connection. Our networking equipment—primarily modems, routers and cable/DSL gateways—which a majority of American homes now have, are also an energy drain. A new report by the Natural Resources Defense Council (NRDC) and Ecova [PDF] found that residential networking costs Americans more than US $1 billion a year, but could be cut by a third using already existing technology. The cumulative energy use, about 8.3 billion kilowatt-hours of electricity, is the equivalent of three large power plants.

“Small network devices suck roughly the same amount of energy around the clock, whether or not you are sending or receiving any data,” said Noah Horowitz, a NRDC senior scientist, in a statement. “But there are steps that manufacturers can—and should—take to make sure these devices are no longer energy vampires.”

Two existing industry standards can help increase the energy efficiency for modems and routers: IEEE 802.3az Energy Efficient Ethernet (EEE) for Ethernet ports, and IEEE 802.11e, which governs automatic power save delivery (APSD).

The standards allow the devices to enter a low-power sleep state when no data is being moved around the network but then quickly wake them up and send data if necessary—quickly enough that consumers shouldn't notice the difference. Without such as sleep mode, a modem's annual energy use is similar to that of a 32-inch flat screen TV.

The U.S.Here is another network faceplate marketer oriented social network that I joined and am promoting with. Environmental Protection Agency is working on an Energy Star specification, but it does not require modems and routers to meet the EEE standard, according to the NRDC report.We are leading pcb manufacturer and factory offering cheap Double layers pcb wholesale,you can buy Cheap Double layers pcb products on our website. The EEE standard could be also used for increased efficiency in computer, printers and other connected devices.

Ecova and NRDC found that networking devices that were labeled as energy efficient did draw the least power. In nearly all cases, it is more efficient to use a gateway that combines modem and routing functionality rather than to have separate devices.

A small but growing piece of the energy consumption from home networking is Optical Network Terminals (ONTs), which are usually attached to the outside of the home to translate optical signals into electronic signals for customers with high-speed fiber optic service. There are about six million ONTs compared to about 40 million modems in the United States.

The difference in efficiency across all the devices tested was related to variation in capability (such as a device that can send 1 gigabit per second, compared to 100 megabit per second).http://www.chinapay.co.uk/,we are here to help you connect to the Chinese market and its potential buying power. But when the study normalized for feature differences, it found that the top 25 percent of devices used one-third less energy. Some of the devices simply always operated at a lower power, while others went into sleep mode when network traffic was low. If all of the residential networking equipment were replaced with more efficient models, the savings would be $330 million annually.
