According to this PC Energy report, US organizations alone waste $2.8 billion every year powering 108 million unused PCs, responsible for approximately 20 million tons of carbon dioxide emissions, roughly equivalent to the emissions of 4 million cars. PCs and monitors are 39% of total ICT emissions worldwide (that account to 2% of the total emissions), equivalent, according to the PC Energy report, to a full year of CO2 emissions from approximately 43.9 million cars. If all the world’s 1 billion PC’s were powered down for just one night, says the PC Energy report, it would save enough energy to light up New York City’s Empire State Building for more than 30 years.

There’s a very simple action anybody can take to reduce emissions and cut energy costs: turn your PC off at night or when it’s not being used. Our Fonera 2.0 can be really helpful for this purpose: if you usually keep your PC on all night to download/upload content from the Net, the Fonera 2.0 can take care of downloading files from BitTorrent, Megaupload and Rapidshare and uploading your pictures and videos to Flickr, Picasa and Youtube, letting you turn off your PC at night, thus significantly reducing your energy consumption and CO2 emissions. If you believe turning your computer off and on every day will somehow damage it, or won’t help you reduce your energy comsumption, read this article from Microsoft.

But how much money can you save? Say you keep a desktop PC, consuming around 100 W, powered up day and night to download content from the Net. If the average price in Europe for a kilowatt hour is €0,18, your PC will cost you around €157 per year. Using a Fonera 2.0 you could keep your PC on for only 10 hours a day, and the Fonera will do the downloading/uploading for you during the night, using only around 3 watts. You’ll save €89 in one year and pay back the €49 investment to buy your Fonera 2.0 in less then 7 months. Furthermore, every year you’ll avoid producing 355 kilograms of CO2. Your PC left on day and night would otherwise emit 629 kg of CO2 in one year, equivalent to driving a BMW X3 SUV for 3600km. Turning your PC off at night and using your Fonera 2.0 for downloading will bring your CO2 emissions down to 273kg per year.

Down/Uploading using 3W? My 2,5″ hard drive with an USB converter consumes 3W on its own (even more at startup, my hub detects this as violation and shuts the port), and 2,5″ may not be the disk of your choice (low energy consumption, but high price per GB). So 3W might be a bit unrealistic. But reality is still far less than the energy consumption of an ordinary x86 server (based on mini-ITX or similar) which some of us use for this task. Will the Fonera 2.0 send idle USB hard disks to standby?

Martin, I totally agree that it will be great to shut down PC’s that are just used for download and leave only the small fonera for those tasks.

However, as I pointed out in the fon forum, there are still stability problems and other usability issues to adress first.
I started using the fonera as a torrent client, but when I saw that from time to time it hangs, I started again leaving my old dell laptop powered all day.
The bad thing is that when it hangs this way (3 green lights on all the time) there is no other way to restart it than walking to the fon spot and reseting with the power plug.
