Could a Swarm of Space Mirrors Replace Much of Europe’s Solar and Wind by 2050?

Summary
Despite its embryonic status, a new study suggests space-based solar power could play a part in the energy transition.
Two designs being developed by Nasa could aid the European transition to net zero by 2050, potentially lowering costs by 7% to 15%, says the study in Joule.
Space-based solar power involves solar panels in space that beam energy down to Earth using microwaves or lasers.
The technology could provide round-the-clock power and would not be dependent on weather conditions, simplifying the energy grid.
The study’s authors said the technology is still at an early stage and the challenge of public acceptance and regulatory issues may be significant.
