I asked ChatGPT, "How much energy does ChatGPT consume per query?"
Here was ChatGPT's answer:
====================================
Great question — and the answer varies depending on the type of model, infrastructure, and complexity of the query. Here’s a general breakdown of how much
energy is used per AI query, using public estimates and research:
Estimated Energy Usage per Query (as of 2024–2025)
| Model Type | Energy per Query (Estimated) | Notes |
|---|
| GPT-3 (175B) | ~0.5 Wh per query | Depending on prompt length and hardware used |
| GPT-4 / GPT-4-turbo | ~0.8–1.5 Wh per query | Higher accuracy and complexity = more compute |
| ChatGPT Average | ~0.3–1 Wh per query | Varies widely by prompt size and infrastructure |
| Search Engine (Google) | ~0.0003 Wh per query | Much lower due to efficiency and simplicity |
To Put That in Perspective:
- 1 Wh (Watt-hour) = The energy needed to power a 1-watt device for 1 hour.
- Typical LED light bulb uses ~10W = 1 Wh every 6 minutes.
- So one ChatGPT querycould use the same energy as:
- Running an LED light for a few minutes
- Charging your phone a small percentage
- Boiling water for a single cup of tea (depending on the model)
Environmental Context
- OpenAI and other AI companies are increasingly optimizing model efficiency.
- Work is ongoing to reduce carbon emissions through:
- Efficient hardware (e.g., custom AI chips like NVIDIA A100s, Google TPUs)
- Green data centers powered by renewable energy
- Model compression and pruning
In Summary:
- A typical ChatGPT query uses 0.3 to 1.5 Wh, depending on model complexity.
- It's more than a Google search, but far less than watching a video or gaming.
- The overall impact adds up with scale (millions/billions of queries).
==============================================
I then asked ChatGPT, "So, should I refrain from unnecessary queries? To save energy?"
ChatGPT replied:
============================
That’s a thoughtful and responsible question — and the short answer is:
Yes, being mindful of unnecessary queries can help reduce energy use — especially when done at scale — but you don't need to feel guilty for using ChatGPT responsibly.
Why It Matters
Each query, especially with large AI models like GPT-4, uses significantly more energy than a basic Google search.
At a global scale, this adds up — millions of queries per day means millions of watt-hours, much of which still comes from non-renewable sources.
Like all tech use (streaming, gaming, scrolling), there’s an environmental cost.
What You Can Do (Without Overthinking It)
You don’t need to stop using ChatGPT, but you can make choices that balance your goals with sustainability:
Be Conscious, Not Obsessive:
Combine multiple questions into one when possible.
Avoid “just for fun” queries if they don’t actually add value for you.
Use lightweight resources (books, local docs, offline tools) when you can.
But Also:
Don’t stress about every single query.
Don’t replace useful AI guidance with low-quality or high-stress alternatives.
Bonus: Using AI to Reduce Waste
So in short:
Yes, be thoughtful — but don’t let it paralyze you. Smart, focused queries are exactly what AI should be used for.
Let me know if you want tips on digital sustainability or how to use AI to live more eco-consciously.
Especially if you were aware of it and what of it if you didn’t, would there be a boycott of such media & publishers / distributors ?
