*Right-Sizing:* Using appropriately sized models for each task, rather than always deploying the largest available.
*Lifecycle Consideration:* Considering the full lifecycle impact of AI systems, including hardware manufacturing.
Net Impact Assessment
The key question isn’t whether AI uses energy but whether its climate benefits exceed its climate costs. For well-designed climate applications, this balance is positive—often dramatically so.
A model using 100 MWh to train might enable grid optimizations saving millions of MWh. An emissions monitoring system might enable reductions far exceeding its operational footprint.
Careful application selection and efficient implementation maximize net climate benefit.
Challenges and Opportunities
AI’s climate applications face various challenges.
