Green energy for telecommunications

8.2 terawatt hours of electrical energy is consumed per year by NTT group companies. This huge amount of energy is used, for example, for fixed telecommunications, mobile communications, and data centers. As network equipment has become more IP-based, the energy consumption required has steadily increased. We have implemented various energy-saving measures to prevent global warming. We introduce the actions we are taking on the strategy of ″Green integration.″ “Green integration” is not limited to telecommunications, and it is a set of solutions that contributes to the environment in terms of energy and structure.
