Thus you are forced into having long transmission lines (on the order of the moon's diameter), sharply restricting your building sites, ... If solar energy sufficient for the needs of the dark half could be generated at the poles (which would always recieve sunlight that is not greatly diminshed by atmosphere as it is on the earth), then the farthest transmission lines would have to reach would be to the moon's equator, at most "only" one quarter the diameter of the moon (still a somewhat long distance).
