Integrated power management

• Integrate power management in all applications, using e.g. the GNOME Power Management Specification API.

• Use less power intensive code paths when system is reported as running on a discharging battery (e.g. defer more work to the server if possible, minimize I/O etc.).
• Also maybe add one or more special 'green/environmental modes', that would also work on desktop systems, which make applications choose power conserving paths at the expense of graphical detail (bling), speed etc.

• As ranking programming operations in terms of power consumptions could easily become an science in its own right, maybe something like a set of power conservancy guidelines for developers (like the HIG) should be issued.
