AbstractTo meet the future needs of energy on Earth, the transmission of solar power from space is being extensively studied. Since the power station will occupy a position in the geostationary orbit and will use radio frequency spectrum for transmission of energy to Earth, the relative benefits of space solar power and space communications should be considered. The resource allocation of orbit-spectrum to a power station requires a sacrifice from space communications as they both utilize similar limited resources. The power station is to energy what communication is to information. While the cost of energy is going up, the cost of information processing, storage, sharing and transmission is decreasing. Also, increased means of communication are used as a measure of energy conservation. With the advent of computer communication and the Large Scale Integrated (LSI) microprocessors, the technique of multiple access, message switching and satellite switching can be cost-effectively combined. The computer-satellite communication will allow information resource sharing among large numbers of users besides the conventional application of space communications. Since space communication means work effectively in many other areas where ultimate energy use and conservation is possible, the space solar power will not be able to compete or substitute on the basis of equality and social benefits. But, as the transmission technology is similar for both areas, the R & D effort for solar power will certainly increase efficiency and reduce cost for space communications.
