Appeal to industry

Would we accept our new car using twice the gas? With PC's we do ...

As THE high tech representative in the home and office, THE progressive industry, ICT should set an example and lead the way. I'd like to see more of a 'hackers' mentality in industry: let us finally make computers behave like they can and should behave!

PC's are idle 90-98% of the time they are switched on. So it is the idle state of a desktop computer where the energy savings must be made. The Energy Star specification draft for 2007 allows for max. 50-60 watt energy use by a idle PC. This must come down to at least 20 watt! And that really is no problem: Using 'of the shelf' laptop-technology, costing only a few dollars/euros, it is quite possible to reach figures well below 20 watt.
