I proposed this at my work, a little over 10,000 pc's, and they decided to go the shutdown the pc at night way instead. They are spending $40.00 initially, PER PC, for a program that shuts down the pc at night and then restarts it in the morning! Each pc is projected to save about $3.00 per month and the program costs $40.00 per year! The license is only good for that one pc and the pc's are replaced every 4 to 5 years. There is an ongoing license fee per year too! The 'company', NO not THAT company, thinks they will save the money in power generation, not electricity costs per pc. I really tried guys, they just said no!
