Button-up and go green. The multi award-winning Eco Button is one of those ideas straight out of the 'now why didn't we think of that' department. Combining an ever-present reminder of the need to save energy (and therefore CO2 emissions), with an easy way of actually doing it, this clever and money-saving device is designed to help you, your colleagues and the whole planet from the scourge of idling PCs.

Imagine how much energy is wasted every time you leave your desk to make a cup of tea. Go out to lunch. Or take, gentlemen, a wee. We know the answer. And it's lots. It seems that, as a species, we're simply rubbish at shutting our computers down for the duration, because, let's face it, they take an age to boot back up again. Easier to leave them on, eh? Easy, yes. But needlessly wasteful.

In one fell swoop, the Eco Button obviates all that shutting down and booting up nonsense. Connected to one's computer by the marvel of USB technology, giving the button a gentle press will automatically activate your computer's deep-level energy-saving 'eco' (or 'sleep') mode.

It will happily doze, using as little as 1.8 watts, with all your programs still open, ready to be reactivated on your return. Simply tap any key (or, in some cases, touch the power on button) and your computer will be instantly restored to life - having saved oodles of watts in the process.

Aggregate all those savings across a whole year, or a whole department, and watts quickly build into valuable Kilowatt Hours. Want to know exactly how much? That's easy. The Ecobutton comes with clever software that carefully records the energy - and money - you've saved.

Then it's over to you and your energy saving finger. Simply press your magic button... and save the planet.
