IT directors have estimated that they could save hundreds of
thousands of pounds through energy saving by using the green
features in Windows
Vista.
Adrian Davey, head of IT at Tube Lines, said, "Our planned
upgrade onto Windows Vista had to be economically efficient. With
2,500 seats, we estimate we would save £40 to £50 in terms of power
savings." Over the life of PCs, Davey said this would equate to
savings worth half a million pounds.
Davey said the energy savings would help Tube Lines meet its
targets to reduce its carbon footprint. Tube Lines is due to roll
out Vista in September 2007.
Geoff Connell, chief information office at the London Borough of
Newham, estimated the council would save £50 per PC across the
5,000 PCs the councils has. "Even with all the internal PR efforts
and green initiates, we found that 1,200 people were still leaving
their PCs on overnight," he said. Connell said he expected he would
save £50 per PC in energy costs by making use of the power-savings
features in Vista.
Energy saving would vary depending on how the PC is used. "if
someone is running a screen saver picture of their family on their
desktop PC, this will consume power from the graphics processor,"
Connell said.
Connell said Newham would upgrade to Vista in 2009.
