Energy per Query

A typical ChatGPT query is about 0.8 Wh. A median Gemini text prompt is about 0.24 Wh. Reasoning and long-context calls, such as GPT-5.5 thinking or Claude Opus on a long document, can use roughly 10–20 times more.

Tree Absorption

A mature tree absorbs approximately 21 kg (48 lbs) of CO₂ per year, helping offset carbon emissions.

Waste Impact

Removing 1 kg of plastic from the ocean prevents ~3 kg of CO₂ equivalent emissions over its lifecycle.

Global Scale

Global data center electricity consumption is projected to reach 1,050 TWh by 2026, with AI as a primary driver of growth.

How We Calculate

Our methodology is based on peer-reviewed research on AI energy consumption

1

Energy Consumption

We estimate energy per query from published figures: Google's Gemini measurement, OpenAI's 2025 ChatGPT average, and independent estimates for GPT-5.5, Claude, and reasoning models. A long prompt or a thinking trace uses more than a short chat.

2

Carbon Intensity

We apply average global grid carbon intensity (~0.4 kg CO₂/kWh) to convert energy usage to carbon emissions.

3

Offset Calculation

We calculate equivalent trees needed (21 kg CO₂/tree/year) or trash collection impact (3 kg CO₂ prevented per kg plastic).

These calculations are estimates based on publicly available research. Actual energy consumption varies based on data center efficiency, renewable energy usage, and specific model implementations.
