Comprehensive Environmental Impact
Google's innovative approach provides the first comprehensive, first-party data on the environmental impact of AI serving at scale. The median Gemini Apps text prompt consumes only 0.24 Wh of energy, generates 0.03 gCO2e, and consumes 0.26 mL of water. These figures are significantly lower than many previous public estimates due to a full-stack measurement boundary and continuous optimization.
Approach Comparison: Energy per Prompt (Wh/prompt)
| Approach | AI Accel. Power | Util. Sample | CPU & DRAM | Idle Machines | Overhead | Gemini Wh/prompt |
|---|---|---|---|---|---|---|
| Existing Approach | 0.10 | Prompts in Top 10% most efficient DCs | 0.04 | 0.02 | 0.01 | 0.10 |
| Comprehensive Approach | 0.14 | Average across fleet | 0.06 | 0.02 | 0.02 | 0.24 |
The "Comprehensive Approach" provides a more accurate and higher figure (0.24 Wh/prompt) because it accounts for a wider range of energy-consuming activities compared to existing, narrower methodologies. This includes host CPU & DRAM, idle machine capacity, and data center overhead, reflecting real-world production environments.
Full-Stack Measurement Methodology
Our methodology addresses a critical gap by proposing a comprehensive, full-stack measurement approach that accounts for all material energy sources. This includes active AI accelerators, host system energy, idle machine capacity, and data center energy overhead (PUE).
Enterprise Process Flow
Identify all LLM models serving the Gemini app
→
Map LLM models to job/machine IDs for PSU energy consumption
→
Measure total user prompt count (Q)
→
Divide each energy component (Ex) by Q to get Ex/prompt
This systematic approach ensures an accurate reflection of energy consumption under diverse real-world conditions, including factors like batch size, latency requirements, and the full energy footprint of data centers.
Driving Efficiency & Sustainability
Google's continuous investment in efficiency across the entire AI serving stack has led to significant environmental impact reductions. Over a year, the median Gemini Apps text prompt has seen a 33x reduction in energy consumption and a remarkable 44x reduction in carbon footprint.
Key Drivers of Efficiency Gains
1. Smarter Model Architectures: Gemini models utilize Transformer architecture with Mixture-of-Experts (MoE) and hybrid reasoning, enabling up to 10-100x efficiency boosts by activating only necessary subsets of a large model.
2. Efficient Algorithms & Quantization: Continuous refinement of algorithms and methods like Accurate Quantized Training (AQT) use narrower data types to reduce energy consumption without compromising quality.
3. Optimized Inference & Serving: Technologies such as Speculative Decoding and distillation (Gemini Flash, Flash-Lite) improve responsiveness and efficiency, allowing for higher batch sizes while meeting latency goals.
4. Custom-Built Hardware & Software Stack: Google's TPUs are co-designed with AI models for high performance per watt. The XLA ML compiler, Pallas kernels, and Pathways systems ensure efficient execution on accelerators.
5. Optimized Idling & Ultra-Efficient Data Centers: Dynamic model movement minimizes accelerator idling, combined with Google's fleet-wide PUE of 1.09 and advancements in cooling systems, further reducing energy and water use.
6. Clean Energy Procurement: Google's commitment to 24/7 carbon-free energy and strategic clean energy procurement has driven a 30% decrease in Scope 2 MB emissions factor from 2023 to 2024, decoupling electricity consumption growth from emissions impact.
