How does Claude 3.7 Sonnet compare?
Detailed Breakdown
Energy Consumption
Claude 3.7 Sonnet consumes approximately 2.78 Wh per query, placing it in the "standard" tier between efficient small models and heavy reasoning models. Despite this moderate energy figure, Claude scored the highest eco-efficiency rating (0.886) among major models when benchmarked on AWS, balancing performance quality against energy cost.
Power Source & Carbon
Anthropic runs Claude primarily on AWS infrastructure in US East (Virginia) and US West (Oregon), with additional capacity on Google Cloud. AWS's "Project Rainier" cluster for Anthropic spans data centers in Pennsylvania, Indiana, and Mississippi. Amazon claims to be the largest corporate renewable energy purchaser for 5 consecutive years and achieved 100% renewable energy matching. However, Anthropic has not published Scope 1, 2, or 3 emissions in any public filing as of 2026.
Water Usage
At approximately 5.2 mL per query (derived from 2.78 Wh at AWS's WUE of ~1.87 mL/Wh), Claude's water footprint reflects its moderate energy consumption. Anthropic has committed to water-efficient cooling systems but has not disclosed specific water usage metrics. AWS data centers use a mix of evaporative cooling and direct air cooling depending on the climate zone of each facility.
