The energy efficiency (measured in bits-per-Joule) of multiple-access wireless data networks is considered via the behavior of Nash equilibria in non-cooperative power control games. Particular issues considered include the effects of multiuser detection and multiple antennas on energy efficiency, energy efficient carrier loading in multi-carrier CDMA systems, and the effects of delay constraints on energy efficiency. Some open problems of interest are also discussed.
