Space-Based Solar Power

Space-based solar power uses orbital equipment to collect sunlight and transmit energy to receiving systems on Earth, potentially supplying electricity when terrestrial solar panels are not producing.

Overview Energy is developing a proposed system using laser or microwave beams and has an agreement with Meta for up to one gigawatt of capacity, though the transmission technology has not been demonstrated at utility scale. The concept’s prospects depend on engineering and safety, launch and infrastructure costs, grid integration, and whether it can compete with established energy sources. Research also has a strategic dimension, including programs in the United States and China.
