Energy consumption is a major contributor to network operating expenditure (OPEX) and also has an impact on CO2 emissions. In developing economies, almost a quarter of new cell sites will be beyond the power grid. The implementation of renewable energy and more energy-efficient equipment can bring significant benefits by helping operators to deal with unpredictable fuel prices.
There is much potential for improving the energy efficiency of traditional mobile networks. Just 15 percent of the energy spent on operating a network is used for forwarding bits, which means that 85 percent of the energy does not contribute to generating revenue.
This white paper describes the major opportunities, as well as the principle methods of achieving the energy efficiency target.
