Good for the Planet, Bad for Me? Intended and Unintended Consequences of AI Energy Consumption Disclosure
Authored by: Michael Klesel & Uwe Messer
To address the high energy consumption of artificial intelligence, energy consumption disclosure (ECD) has been proposed to steer users toward more sustainable practices, such as choosing efficient small language models (SLMs) over large language models (LLMs). This presents a performance-sustainability trade-off for users. In an experiment with 365 participants, we explore the impact of ECD and the perceptual and behavioral consequences of choosing an SLM over an LLM. Our findings reveal that ECD is a highly effective measure to nudge individuals toward a pro-environmental choice, increasing the odds of choosing an energy efficient SLM over an LLM by more than 12. Interestingly, this choice did not significantly impact subsequent behavior, as individuals who selected an SLM and those who selected an LLM demonstrated similar prompt behavior. Nevertheless, the choice created a perceptual bias. A placebo effect emerged, with individuals who selected the "eco-friendly" SLM reporting significantly lower satisfaction and perceived quality. These results highlight the double-edged nature of ECD, which holds critical implications for the design of sustainable human-computer interactions.

The Real Cost of Large-Scale AI
Modern AI models, particularly LLMs, demand significant environmental resources. Training a single model like BLOOM can incur over 50 tonnes of CO2 emissions, and GPT-3 training consumes 700,000 liters of freshwater. Increasingly, inference (model operation) accounts for an estimated 60% of AI's total energy consumption, highlighting a critical need for sustainable strategies. The challenge is exacerbated by the exponential increase in queries and computationally intensive prompting techniques, shifting the energy cost from training to continuous user-driven operations.
| Feature | Large Language Model (LLM) | Small Language Model (SLM) |
|---|---|---|
| Energy Efficiency | Energy Inefficient (e.g., F-score) | Energy Efficient (e.g., B-score) |
| Performance | High (e.g., 5-star rating) | Lower (e.g., 3-star rating) |
| Resource Demand | High parameter count, high energy | Fewer parameters, low energy |
| User Perception (without ECD) | Often perceived as higher quality | Often perceived as lower quality |
Nudging for Pro-Environmental Behavior
The study applies Nudge Theory to promote Pro-Environmental Behavior (PEB) in AI model selection. Nudges, subtle changes in choice architecture, can significantly influence behavior without restricting freedom. Providing Energy Consumption Disclosure (ECD) acts as a nudge, expected to encourage users to select more energy-efficient SLMs. Prior research shows nudges can yield a medium effect size in environmental contexts, making this a promising strategy for sustainable AI.
Unintended Consequences: Moral Licensing & Placebo
The research explores potential unintended consequences like Moral Licensing, where performing a 'green' act might subconsciously justify less virtuous behavior later, potentially leading to increased AI usage. It also investigates the Placebo Effect, where user expectations of model performance (framed as lower for SLMs) might negatively influence perceived quality and satisfaction, even if the underlying technology is the same. This highlights the complex psychological impact of disclosure on user experience.

The Double-Edged Sword of Energy Disclosure
While Energy Consumption Disclosure (ECD) effectively nudges users towards energy-efficient SLMs (with over 12x higher odds of selection and a 39.3% preference in the treatment group), it creates an unintended perceptual bias. Users choosing the 'eco-friendly' SLM, framed as lower performance, reported significantly lower satisfaction and perceived quality. This highlights a critical trade-off: promoting pro-environmental behavior via transparency can inadvertently degrade the user experience. Designers must navigate this by exploring alternative framings, co-benefits, or automatic routing to avoid burdening users with this performance-sustainability dilemma.
Designing Sustainable AI Interactions
Designers should leverage ECD by adding simple labels to existing interfaces to foster PEB. To mitigate the placebo effect, they should emphasize SLM co-benefits (e.g., faster response times), add qualitative strengths (e.g., 'concise'), or use objective performance metrics. Personalization with tailored nudges based on Pro-Environmental Attitude (PEA) can further enhance effectiveness. Considering the SLM as the default option or implementing dynamic model routing for queries can reduce user burden while maintaining autonomy and promoting sustainable AI.
