Reducing Carbon Dioxide emissions is an important global environmental issue. Over the recent years, wireless and mobile communications have increasingly become popular with consumers. Today's typical wireless access network consumes more than 50% of the total power consumption of mobile communications networks. Growth of mobile Internet service usage is expected to drive the growth in wireless access data rates and usage. The current rate of power consumption per unit of data cannot be sustained as one moves towards broadband wireless access networks and anticipated increases in wireless data traffic.
