OpenAI's internal target of ~250 GW of compute capacity by 2033 would require about as much electricity as the whole of India's current national electricity consumption[0].

My favorite factoid is that the most energetic power production facility on the planet is the Three Gorges Dam, with a nameplate capacity of 22.5GW.

That dam took 10 years to build and cost $30B.

And OpenAI needs more than ten of them in 7 years.
