Musk Abandons Solar Energy: xAI Switches to Natural Gas

Elon Musk's energy strategy has undergone a significant shift. Instead of developing solar energy on Earth, his companies are betting on natural gas and speculative orbital data centers — a completely opposite course from the "solar-electric economy" he promised.

Natural Gas for xAI

xAI, which develops large language models, will transition primarily to natural gas to power its data centers. This solution allows faster deployment of capacity and minimizes costs compared to waiting for solar panels and battery systems to be installed. Natural gas provides reliable power and allows infrastructure scaling without delays associated with purchasing, delivering, and installing renewable energy sources. For a company racing to compete with OpenAI and other AI leaders, this is an optimal choice.

The choice of gas reflects practical necessity: training modern AI models requires enormous amounts of electricity. Data centers consume megawatts around the clock, and the company cannot afford to wait until solar systems are ready.

SpaceX's Orbital Data Centers

SpaceX, meanwhile, is going in a completely different direction: the company is developing the concept of orbital data centers — servers located in space. The idea is that satellite data centers could operate with minimal cooling costs, since heat in the vacuum of space radiates directly into the environment. Although the project sounds futuristic and ambitious, it remains a costly and speculative idea, far from commercial realization.

Theoretically, orbital centers could serve global networks with ultra-low latency and significantly save electricity on cooling. However, the technology is still in very early stages of development.

Where Did Solar Energy Go?

Musk has publicly spoken for many years about a "solar-electric economy" of the future. In this vision, solar panels installed on the roofs of homes and buildings would provide humanity with clean electricity. Tesla, Musk's renewable energy company, actively sells solutions for residential and industrial solar generation. This is a logical part of his environmental philosophy.

However, the current solutions of his own AI companies are going in a completely different direction. This inconsistency raises a number of questions:

• Did Musk realize that solar energy doesn't scale fast enough for growing AI demands?
• Is natural gas only a temporary solution until renewable sources mature?
• Are orbital data centers a serious plan or a marketing move?
• Will interest in clean energy return once it becomes cheaper and more efficient?

What This Means

Practically, this means that the early stages of the AI revolution will be powered by fossil fuels. The question is only how quickly the industry will transition to cleaner solutions when they become price and reliability competitive. For now, Musk's practical interests have proven more important than his public climate commitments.
