A neural network training session uses 4.8 kilowatts of power per hour. The lab operates the system for 15 hours per day, but energy usage is reduced by 20% during off-peak hours (6 PM to 6 AM). How many kilowatt-hours are consumed in one day?

**How A Neural Network Training Session Uses 4.8 Kilowatts—and What That Means for Energy in AI** With AI systems transforming industries from healthcare to finance, the behind-the-scenes cost of powering neural network training has become a topic of quiet but growing interest in the U.S. demand for efficiency and sustainability. Typically, a single training session runs at 4.8 kilowatts for 15 hours each day. Though that volume might seem straightforward, powerful energy savings are achievable through smart scheduling—especially during off-peak hours from 6 PM to 6 AM, when usage drops by up to 20%. This strategic reduction shapes actual daily consumption in meaningful ways, influencing both operational costs and environmental impact. **Why This Pattern Matters in Today’s Energy Landscape** Across the U.S., data centers and AI labs face rising electricity demands and calls to optimize consumption amid climate and cost concerns. Neural network training sessions require substantial computational power, often generating heat and high energy draw—4.8 kilowatts per hour reflects real-world system load. The 15-hour daily operation underscores consistent demand, but the off-peak energy discount shows how timing affects total consumption. Reducing usage by 20% during overnight hours cuts both expense and carbon footprint, aligning with broader efforts in sustainable AI development.
