# Neuro-Symbolic AI Cuts Energy Use 100x While Boosting Accuracy

> Researchers at Tufts have built a neuro-symbolic system that pairs a neural network with old-fashioned symbolic reasoning, and the efficiency numbers are eye-catching. Training consumed about 1 percent of the energy a conventional model would need, and running it used roughly 5 percent, while accuracy went up rather than down. On the Tower of Hanoi puzzle, a classic test of step-by-step logic, the hybrid hit 95 percent success against 34 percent for a standard system, and it trained in 34 minutes instead of more than 36 hours. The trick is letting the system reason logically instead of brute-forcing its way through trial and error. Why this matters is the power bill. US data centers and AI already drew 415 terawatt-hours in 2024, more than a tenth of national output, and that figure is expected to double by 2030. If approaches like this generalize beyond puzzles, they hint at a path where better AI does not automatically mean an ever-larger appetite for electricity.
