With the rapid emergence of low-altitude wireless networks for the sixth generation (6G), terrestrial networks are extending their coverage into three-dimensional airspace. Different from traditional terrestrial communication, the energy consumption in groundto- air (G2A) coverage increases exponentially with the aerial node's altitude, constraining the scalability and sustainability of the network. In this work, a transformative evolution toward embodied intelligent agent (EIA)-enabled networks is envisioned, where terrestrial base stations are no longer passive communication nodes but intelligent entities capable of sensing, reasoning, and acting upon both wireless and energy environments. By opening interfaces between wireless and energy networks, energy is elevated from a static constraint to a controllable physical resource. This shift enables networks to dynamically redistribute energy, coordinate cooperative actions among agents, and align spatial energy availability with G2A coverage demand through a closed sensing-decision-action loop. An energy-intelligence- communication co-designed architecture is introduced to support this evolution, incorporating cross-layer orchestration, agent-to-agent coordination, and interpretable cooperative mechanisms that prevent agents' self-preserving behaviors under conflicting objectives. By embedding embodiment and energy awareness into network design, this paradigm offers a scalable and low-carbon pathway for sustainable G2A coverage, shaping the long-term development of embodied low-altitude wireless networks.
