This paper attempts direct comparisons between ground-based solar and wind electrical power generation systems and those of Space Solar. Ground solar and wind are the two major popularly proposed replacements for carbon-based energy. Potentially, these could become very large base load electrical power sources due to: 1) their current political recognition as the desired replacement sources and 2) to their widespread availability. However, they have severe physical limitations. For Space Solar, only those aspects that are critical for valid comparisons to the ground based systems are give attention. The focus is primarily on physical comparisons, such as actual areas of land and amounts of equipment required to produce given amounts of base load power.
