Type I

A type I civilization has mastered all the energy available to their home planet, available from a neighboring star. It extracts its energy, information, and raw-materials from fusion power, hydrogen, and other "high-density" renewable-resources; is capable of interplanetary spaceflight, interplanetary communication, mega-scale engineering, and colonization, medical and technological singularity, planetary engineering, world government, trade and defense, and stellar system-scale influence; but is still vulnerable to extinction.
