e& establishes climate innovation hub and pilots solutions to lower emissions and energy usage. Since 2020, the cost of energy has risen significantly, increasing telcos’ operating costs, either directly, where they are using generators, or indirectly, where they are using the power grid. At the same time, base stations, which account for most of the energy consumption for a typical mobile network, are increasingly being equipped with 5G radios, which enhance the user experience, but can also consume more power. Against this backdrop, telecoms operators are trying to reduce greenhouse gas emissions, as well as fuel costs. To do that without impacting their customer experience, they need to maximise the use of renewable energy, such as solar and wind power. e&, a leading operator in the Middle East, is aiming to achieve net zero greenhouse gas emissions2 by 2030.
