Green energy use and tablet computing

There’s been some talk lately about how the internet is moving towards being mobile. This means big change in terms of the way we interact with the net. Where once it was a matter of sitting in front of a big screen, with a PC plugged into the mains, people are – in greater numbers all the time – accessing web pages via a wide range of portable and mobile devices.

Just look at the travellers on any commuter train. Half of them will be staring into the small screen of their Android, Symbian or Apple OS phone. Some will be catching up with the latest news from the website of their newspaper of choice, others (including me) will be trying to figure out how to get three stars on every level of Angry Birds (then giving up and seeking assistance from a YouTube video) and then there will be the people who only ever seem to do the facebook thing on their smartphone. It’s a whole new world…

And it’s a whole new world that’s just gotten newer with the proliferation of tablet computers. Small enough to take on the bus, big enough to use the internet without squinting and magnifying the page.

Unsurprisingly, tablet devices don’t use as much juice as a PC with a disk drive, screen, fans, optical drive and so on. But how green are they?

Well, a quick swatch at the Apple site for the new ipad brings up this information:

  • Arsenic-free display glass
  • BFR-free
  • Mercury-free LED-backlit display
  • PVC-free
  • Recyclable aluminium and glass enclosure
(BFR = brominated flame retardant, since you ask)
The glass and aluminium make up a fair percentage of the machine’s weight, so I’d rate this one pretty high on sustainability and energy use. Apples (well most of the ones I eat anyway) are green. Glad to see that this one is too.
