Hyper-efficient computers of alien civilizations may have an energy signature — Phys.org
Advanced extraterrestrial civilizations, if they use extremely efficient computers, may produce a distinctive energy signature that could potentially be detected. Phys.org writes about this possibility, considering computing as one of the possible signs of a technologically advanced civilization.
Growing demand for computing
The publication notes that artificial intelligence is likely to remain a component of modern technology. AI's need for computing power has already overloaded chip manufacturers and energy companies.

At the same time, the author suggests that the current hype around AI may turn out to be a bubble ready to burst. However, in his assessment, this would not mean abandoning computers.
Hypothesis about advanced civilizations
Since their emergence, computers have become more powerful, while human civilization has become increasingly dependent on computing. If computing power is a defining feature of any advanced civilization, then the most advanced civilizations in the Universe would seek to make computing as powerful and efficient as possible. The publication links the possibility of searching for a distinctive energy signature to this hypothesis.
