Economic evaluation of solar power satellite system: A comparison between SPS & other renewable resources

As one of the suggestions and as an outlook in the field of energy generation, it is collecting solar power in space for use on earth within the concept of solar power satellite. Todays, solar power satellite is known as a new stronger renewable energy resource. Because of interest in alternative energy sources, in this paper an economic evaluation comparison have been innovated between solar power satellite and the other renewable resources by means of net present value. Framework for calculation of net present value is described and the results are shown as two statements of present and future.
