The annoying application letter, the school essay, the seminar paper, that and much more can now be done like this: write in a text box on the Internet what it should contain and how long it should be, bang, done. How cool is that! It only took about two months, and by January 2023, 100 million people had already tried out the AI application Chat-GPT from the company Open AI. Never before has a company gained so many users so quickly. Since then, there has been a lot of speculation about what generative artificial intelligence (AI) can do, i.e. AI that can create something new from input. How schools and universities should deal with it. What AI means for the job market. How dangerous an out-of-control AI is. However, one aspect has so far been neglected: energy consumption.
