A study by King's College London suggests that space-based solar power (SBSP) could reduce Europe's ground-based renewable energy needs by 80% by 2050. SBSP systems utilize large satellites in high Earth orbit to collect solar energy and transmit it back to Earth.

A UK government study indicates small-scale SBSP could compete with conventional electricity sources by 2040. However, the technology's deployment will require significant investment in research and development, estimated at €15.8 billion, and faces challenges related to cost, safety, and environmental impact.
