RE: [hreg] Trying out an energy conservation program at work.
- Thanks! They are on stand by 24/7. This gives me something to start with. We also have laptops on our desks. We have about 3,000 employees in all. I'm thinking if it goes well I will pass on to the entire company. I appreciate it.

Typical desktop machine draws between 80-120 watts, with a monitor (active,

$.14/kwh, turning them off for 8 hours a day would save about $500/month.
I'm guessing it would actually be more if they are currently left on during

My 17” monitor uses 59 Watts when being used, and 1 Watt when in standby mode.
I have a Sun server that uses 155 Watts, so most PCs are going to use significantly less.
My laptop uses 18 Watts when being used and 7 Watts when turned off.
