China is pursuing a bold and massive initiative—constructing a one-kilometer-wide solar power station in space. Engineers have likened the scale of the project to relocating the enormous Three Gorges Dam into orbit. The aim is to capture solar energy more efficiently and beam it back to Earth.
Once deployed, the station will remain in a geostationary orbit 36,000 kilometers above Earth, where it can continuously absorb sunlight, unaffected by weather, clouds, or darkness—unlike ground-based solar panels. The harvested energy will be transmitted to Earth using advanced microwave technology.

Experts believe this space-based solar power system could be up to ten times more efficient than traditional terrestrial panels. It may even generate as much energy as the global annual oil consumption.
Construction began in 2019 in Chongqing, China. To transport components into space, China plans to use its next-generation Long March-9 rocket, currently in development.
If successful, the project could represent a major breakthrough in clean energy and reshape global energy strategies by tapping into space as a significant power source
