Every SDXL image uses something like 0.5 Watt-hour. That means that 2000 sdxl images uses about 30 cents of electricity. If we multiply that by 30x for video (a fair assumption for models like minimax H3, which take that much longer to make video), that means you get almost 700 5-second videos for a dollar of electricity, which is about a kilo of carbon dioxide. More or less depending on where your electricity comes from.

It takes about 7 minutes for my RTX 5090 to generate a 15 second video with MiniMax H3. At 600 watts, that's 252,000 watt-seconds, or 0.07 kilowatt-hours.
My electricity is 18 cents/kWh, so $0.0126. Just a little over a penny.
No way gpt-image-2 is as cheap as SDXL. (I dont concern about gpt-image-2's consumption either, just pointing out it's not a good comparison)
People always napkin math something low, and then every academic who formally studies it ends up with a much higher estimate.
I await OpenAI's carbon footprint field.
