The delta-v from LEO to the moon is 6.5km/s. However, from the moon to LEO is less because of aerobraking and/or magnetic launch. In fact, if someone in the right situation wants to get from ground on the moon, to earth ground it might take no fuel at all. Something assembled from materials on the moon would be easier to place in orbit above earth than anything made on earth itself. Go Go Space Power Satellites! Click the image for a larger version.
