AI vs Netflix: which uses more water and energy?

An hour of streaming uses about 0.08 kWh across devices, network and data center; at Mid water terms, roughly 0.4 liters. That equals about 55 ChatGPT prompts. A nightly episode habit out-consumes a daily chat habit; your TV is the bigger pipe.

Prompt: one typical ChatGPT exchange at the Mid scenario (cooling plus the water behind the electricity). Item: its full water footprint, as published by the source.

Streaming had its own scare cycle in 2019 ('one hour = two fridges!') before careful work by the IEA and Carbon Trust landed near 0.08 kWh per viewing hour, most of it in the viewing device. AI is living the same cycle with the boundaries drawn even less consistently, which is precisely what our scenario toggle is for.

Per hour of attention, chat is light: you'd need to fire off a prompt every minute of the show to match the show. Video generation flips the comparison: a single 5-second AI clip at our mid value (150 Wh) costs the same energy as roughly two hours of streaming, and the only public measurement of a current-quality open model (~940 Wh, MIT Technology Review 2025) costs more than an entire evening. The interesting line isn't AI vs Netflix; it's text vs video, in both directions.
