Detailed Breakdown
Energy Consumption
Sora 2 Pro is the premium tier of Sora 2, priced at $0.30-0.50 per second of video versus $0.10 for standard Sora 2. Using price as a compute proxy — the only public signal, since OpenAI discloses nothing — we estimate ~3.5x standard Sora 2's energy, or ~2,100 Wh (2.1 kWh) per 10-second clip. That makes it the most energy-intensive generation in our dataset: one clip ≈ 7,000 Google searches.
Power Source & Carbon
Runs on the same Azure/multi-cloud fleet as other OpenAI models (~437 gCO2/kWh blended). The consumer Sora app was discontinued in April 2026; the API remains available until September 2026.
Water Usage
At ~7.6 litres per 10-second clip (3.6 L/kWh combined water factor) — more water than a person drinks in two days, for one video.
About Sora 2 Pro
Sora 2 Pro sits at the high end of AI energy consumption at 2.10 kWh per generating one short video clip — over 7000x what a Google search uses. OpenAI's video generation model, released in September 30, 2025, premium sora tier — higher fidelity at 3-5x the compute cost. The extreme energy cost reflects the computational complexity of video generation: generating coherent frames across both space and time.
These figures are estimates derived from hardware specifications and API benchmarks — OpenAI has not published official energy data for Sora 2 Pro. Actual consumption may vary significantly depending on batching, quantisation, and infrastructure optimisations that we cannot observe from outside.
Sora 2 Pro in Context
The efficiency alternative
Stable Video Diffusion performs the same type of task using just 150.0 Wh per query — 93% less energy than Sora 2 Pro. For a user sending 25 queries per day, switching would save 17793.8 kWh per year.
The video generation premium
One Sora 2 Pro generation uses 2.10 kWh — the equivalent of 175 full smartphone charges. Video generation requires running a diffusion model across both spatial and temporal dimensions, making it fundamentally more compute-intensive than text or image tasks. This is not an efficiency problem to be solved; it is an inherent characteristic of the task.

Calculate My ComputeFrequently Asked Questions
How much energy does Sora 2 Pro use per query?
Each Sora 2 Pro query consumes approximately 2.10 kWh of energy. This is 7000x more than a traditional Google search (~0.3 Wh).
What is Sora 2 Pro's carbon footprint?
Based on the carbon intensity of Azure / Multi-cloud, each query produces approximately 918.0 g of CO2. The grid in this region has a carbon intensity of 450 g CO2/kWh with 25% renewable energy.
How much water does Sora 2 Pro use?
Each query consumes approximately 7.56 L of water, primarily used for cooling the data centers that process the request.
How does Sora 2 Pro compare to a Google search?
A Sora 2 Pro query uses 7000x more than a Google search in terms of energy. A Google search uses approximately 0.3 Wh, while Sora 2 Pro uses 2.10 kWh.
