Meta says it signed a deal for up to 1GW of space solar energy from Overview Energy, which seeks to collect sunlight in satellites and is planning a 2028 demo

Meta just signed a deal that sounds straight out of science fiction. The company has partnered with Overview Energy to secure 1 gigawatt of solar energy collected in space. Yes, space.

Overview Energy is building satellites designed to capture sunlight in orbit. The startup plans to demonstrate the technology in 2028. If it works, the energy would help fuel Meta's increasingly power-hungry AI data centers.

The math problem facing every major AI player right now is simple: training and running massive models requires enormous amounts of electricity. Earthbound renewables can only scale so fast. Space-based solar bypasses weather, nighttime, and land constraints entirely.

It's a massive bet on unproven tech at commercial scale. But 1GW is no small commitment — that's roughly enough to power a mid-sized city. Meta is clearly willing to look beyond the atmosphere to keep its AI ambitions on track.
