Gemini 2.0 Flash Environmental Impact

Energy Consumption

Gemini 2.0 Flash is one of the most energy-efficient AI models available, consuming approximately 0.08 Wh per median text prompt. Flash models are optimized for speed and throughput, using aggressive distillation and quantization techniques. Google's 33x efficiency improvement between May 2024 and May 2025 applies across the Gemini family.

Power Source & Carbon

Runs on Google's custom TPU v5e/v6e chips across its global data center network. Google claims 100% renewable energy matching and achieves a PUE of 1.10 — among the most efficient in the industry.

Water Usage

At approximately 0.09 mL per query, Gemini 2.0 Flash has an effectively negligible water footprint — less than a single drop of water per query.

How much energy does Gemini 2.0 Flash use per query?

Each Gemini 2.0 Flash query consumes approximately 0.08 Wh of energy. This is about the same as a traditional Google search (~0.3 Wh).

What is Gemini 2.0 Flash's carbon footprint?

Based on the carbon intensity of Google global network (64% renewable), each query produces approximately 0.01 g of CO2. The grid in this region has a carbon intensity of 300 g CO2/kWh with 64% renewable energy.

How much water does Gemini 2.0 Flash use?

Each query consumes approximately 0.09 mL of water, primarily used for cooling the data centers that process the request.

How does Gemini 2.0 Flash compare to a Google search?

A Gemini 2.0 Flash query uses about the same as a Google search in terms of energy. A Google search uses approximately 0.3 Wh, while Gemini 2.0 Flash uses 0.08 Wh.
