wallpaper with power consumption

Computer wallpaper like the one shown below lists CPU & RAM but not power usage. Wallpaper should disclose both the ability and liability.

This wallpaper(BgInfo.bmp) is generated using 'BgInfo', a SysInternals tool.

Wall-paper with power consumption.

I measured the power consumption and then inserted those details in 'BgInfo.bmp' using Adobe PS.

Computer manufacturer's like HP, Dell, IBM have the ability to provide bitmaps containing power usage. There is a debate about accuracy of power measurements. I think the accuracy is secondary; goal is to make people set PC to stand-by mode, turn off monitor etc....

When someone logs in to a machine, wall-paper should inform them about power consumption.
