Is ChatGPT Worse for the Environment Than Google Search?

Yes, ChatGPT typically uses 10 to 100 times more energy per query than a standard Google search.
That’s because Google mostly retrieves indexed pages, while ChatGPT generates new responses in real-time using large language models that require intense computational power.
The more complex the model (like GPT-4), the more energy it consumes.
In short: generative AI is powerful, but energy-hungry.
How much energy does ChatGPT use per question?
While OpenAI hasn’t published exact figures, independent researchers estimate that a single ChatGPT query consumes between 2.9 and 9 watt-hours depending on model complexity and infrastructure.
For comparison:
A Google search = ~0.0003 kWh
A ChatGPT query = ~0.005–0.01 kWh
Multiply that by millions of users - and the energy usage adds up fast.
Can AI be carbon neutral?
It can - but it requires active effort.
Most AI tools today don’t offset their carbon footprint. But platforms like ViroAI estimate energy use per query and fund verified clean energy projects to neutralize that impact in real time.
What is sustainable AI?
Sustainable AI refers to artificial intelligence systems that are designed, deployed, and maintained in a way that minimizes environmental harm and often supports climate-positive outcomes.
This includes:
Reducing energy usage during training and inference
Powering servers with renewable energy
Offsetting carbon emissions tied to usage
Creating value beyond performance - like supporting environmental initiatives
What is the carbon footprint of AI in general?
Training large AI models like GPT-4 can produce hundreds of metric tons of CO₂ emissions. Even small-scale usage adds up when millions of people are generating queries daily.
It’s not just about how smart the model is — it’s about how sustainably it's used.
How is ViroAI different from regular AI tools?
ViroAI does everything other AI chat tools do — generate content, answer questions, help you plan, code, or create — but with one major difference:
🟢 Every chat funds clean energy.
We calculate estimated energy usage per query and support climate projects that help offset it - in real time.
