NASA Report Sparks Debate over Cost Effectiveness of Space-Based Solar Power

NASA has released a report on space-based solar power that acknowledges its viability, but questions its cost-effectiveness. 

While NASA grants that the technology could be used as a renewable source of energy by 2050, they raised concerns as to its potential cost vis-a-vis terrestrial generation, which sparked responses focused on whether NASA’s cost assumptions were accurate or overly pessimistic.
