How energy used in communication?

Energy used in communication primarily comes from the devices and infrastructure that transmit, process, and store information. This includes the electricity consumed by servers, data centers, networking equipment, and end-user devices like smartphones and computers. Additionally, wireless communication relies on energy-intensive technologies such as cellular towers and satellites. As digital communication continues to grow, the energy consumption associated with it is becoming a significant concern, prompting efforts to improve efficiency and explore renewable energy sources.
