Artificial intelligence’s growing demand for computing power is pushing data centers to consume massive amounts of electricity. Jeff Bezos, Amazon's founder, has predicted that within 10 to 20 years, gigawatt-scale data centers will be built in space, leveraging constant solar power to meet this surge in demand.
Such facilities could exceed the performance and energy efficiency of terrestrial data centers. Speaking at Italian Tech Week, Bezos highlighted the advantages of space-based solar energy, which operates continuously, unaffected by clouds or weather disruptions.
This solar access makes the space an attractive location for future data centers, especially as AI workloads continue to increase globally.
Why does Bezos see space as ideal for data centers?
Bezos explained that the key benefit of space-based data centers is their uninterrupted access to solar power. On Earth, data centers rely on power grids that are challenged by weather and day-night cycles.
In space, solar power is available 24/7, providing an efficient and sustainable energy supply for AI training clusters.
He described these clusters as massive computing groups that require an enormous amount of energy, far exceeding typical workloads.
Space also eliminates weather risks and allows natural cooling techniques, which can reduce operational costs.
Did you know?
Space-based data centers can use solar power 24/7 without interruption from weather.
What energy challenges do current data centers face?
Data centers on Earth are rapidly increasing their electricity usage, currently consuming 4.4% of US power and projected to reach 9.1% by 2030, due to the growth of AI.
Generative AI models consume seven to eight times more energy than standard workloads, driving demand for sustainable solutions.
The rising consumption strains power grids and increases costs. Traditional data centers face challenges in upgrading their infrastructure quickly enough to keep pace with the energy demands of AI, prompting the exploration of alternative models, such as those in space.
Which companies are pioneering orbital data centers?
Several companies are entering the space data center race. StarCloud plans to launch satellites laden with Nvidia GPUs capable of delivering 100 times more compute power than previous space operations. Their goal is to create extensive orbital AI training clusters.
This builds on trends where space technology supports Earth applications, as seen with satellites for weather and communications. Bezos considers this development to be the next logical step toward fully space-based manufacturing and computing.

What technical hurdles must be overcome?
Bezos acknowledged several challenges, including the high cost of rocket launches, risks of failed launches, and the difficulty of maintaining and upgrading hardware in orbit.
Current rocket launch costs and technical complexity remain barriers. Maintenance in space is cumbersome, and upgrades are limited compared to terrestrial centers.
Addressing these issues will require innovation in spacecraft reliability, remote repair technologies, and cost-efficient launch methods to make space data centers a feasible option.
How will space data centers impact Earth's power grid?
If successful, space data centers could significantly reduce Earth-based data center energy consumption by offloading the most power-hungry AI workloads to orbit. This would ease power grid demands and lower environmental impact.
Bezos predicted that within decades, space centers will be cheaper to run than terrestrial ones, reshaping how computing infrastructure is built and maintained.
This shift could herald new efficiencies and tech breakthroughs driven by space-based resources. The vision of space-based data centers remains ambitious but promising.
As AI and data demands soar, leveraging continuous solar power and orbital infrastructure could redefine the future of computing, ushering in a new era where space technology enriches life on Earth.
