Vista vs XP Sustainability

I thought this was intresting in light of most campusus be commited to green.   


1. Windows Vista can reduce electricity costs. Universitites can save up to $11 per system, per year by switching to Windows Vista, due to the default power management settings. For a school with 5000 users, this means up to $47,000 of bottom line dollars can be saved annually.


2. The Vista Sleep state is more reliable than XP. Computers resume from Sleep in two seconds, which is about the same time it takes a screen to resume from Idle mode in Windows XP.


3. Power consumption reduction translates into direct CO2 savings. Carbon dioxide emissions are reduced by up to 67 kg of carbon dioxide per desktop PC, per year. For a school with 5000 users, this is 288 tonnes of carbon dioxide emissions reduced.


4. Aero graphics have no effect on overall power consumption. Organizations should take advantage of Aero since it does not have a significant impact on electricity usage.


Here is a link to where you can find the study:


Also please note that the Watts used in laptop scenario for playing music or doing word doc is sub 30watts.
