Why Solar Power Belongs on Earth

Bloomberg Opinion’s Mark Gongloff argued this week that terrestrial solar power is a more practical and advantageous choice than orbital solar farms. Gongloff stated that while space-based solar power has been a concept for decades, its implementation faces significant hurdles that make it less viable than Earth-based solutions. He highlighted the immense cost associated with launching and maintaining solar panels in orbit, a factor that would likely make the energy produced prohibitively expensive. Furthermore, the logistical challenges of transmitting power from space to Earth, including the need for massive receiving stations and potential atmospheric interference, add further complexity and cost. Gongloff emphasized that advancements in terrestrial solar technology, such as increased efficiency and reduced manufacturing costs, continue to make solar power an increasingly competitive and accessible energy source on Earth. He pointed to the rapid deployment of solar farms globally and the ongoing innovation in battery storage as evidence of Earth-based solar's robust and improving capabilities. The argument posits that focusing resources on optimizing and expanding solar energy infrastructure on the planet offers a more immediate, cost-effective, and scalable path to achieving clean energy goals compared to the speculative and technically demanding prospect of space-based solar power.
