How does Imagen 4 compare?
Detailed Breakdown
Energy Consumption
Imagen 4 generates images at up to 2K resolution with significantly improved text rendering. At ~2.8 Wh per image (1024x1024), it is slightly more energy-intensive than Imagen 3 but produces substantially higher quality. Fast variant available at lower cost ($0.02/image).
Power Source & Carbon
Runs on Google's TPU infrastructure with 100% renewable energy matching.
Water Usage
At ~3.0 mL per image, benefiting from Google's efficient cooling.
About Imagen 4
Imagen 4 is a image generation model from Google, released in February 1, 2026. Google's latest image model — up to 2K resolution, improved text rendering. Each query uses 2.8 Wh of energy and produces 0.36 g of CO₂. That's 9x the energy of a Google search — reflecting the computational demands of image generation. It ranks in the top quartile of image generation models for energy efficiency (#2 of 16).
Imagen 4 benefits from running in Google Global Network, one of the cleaner grid regions in our dataset at 300 gCO₂/kWh with 64% renewable energy. The same model running in a coal-heavy region would produce significantly more carbon per query.
These figures are estimates derived from hardware specifications and API benchmarks — Google has not published official energy data for Imagen 4. Actual consumption may vary significantly depending on batching, quantisation, and infrastructure optimisations that we cannot observe from outside.
Imagen 4 in Context
Your yearly Imagen 4 footprint
At 25 queries per day, your annual Imagen 4 usage consumes 25.6 kWh — roughly what a fridge uses in a month. That produces 3.3 kg of CO₂.
Image vs text: the energy gap
Generating one image with Imagen 4 uses 9x more energy than a text conversation with ChatGPT. The diffusion process that creates images requires many iterative passes through the model, each refining the image from noise — far more compute per output than generating text one token at a time.

Calculate My ComputeFrequently Asked Questions
How much energy does Imagen 4 use per query?
Each Imagen 4 query consumes approximately 2.8 Wh of energy. This is 9x more than a traditional Google search (~0.3 Wh).
What is Imagen 4's carbon footprint?
Based on the carbon intensity of Google global network (64% renewable), each query produces approximately 0.36 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 Imagen 4 use?
Each query consumes approximately 3 mL of water, primarily used for cooling the data centers that process the request.
How does Imagen 4 compare to a Google search?
A Imagen 4 query uses 9x more than a Google search in terms of energy. A Google search uses approximately 0.3 Wh, while Imagen 4 uses 2.8 Wh.
