What's Happening?
A study conducted by researchers from King's College London and Xi'an Jiaotong University proposes that space-based solar power could significantly contribute to the European Union's goal of achieving net-zero greenhouse gas emissions by 2050. The study analyzed two NASA designs for space-based solar power systems, which involve collecting solar energy in space and transmitting it to Earth via microwaves. These systems could provide consistent power supply, reducing reliance on fossil fuels and cutting battery usage by more than two-thirds. The researchers estimate that space-based solar power could be more cost-effective than terrestrial solar systems, assuming continued reductions in launch costs.
