To put a bit of context on those, 50GWh is a single medium sized power station running for 2 days. To create something that is being used around 10 million times a day all over the world.
At 10 million queries per day that puts the usage per query at 100-500 Wh, about the amount of energy used by leaving an old incandecent lightbulb on for an hour, or playing a demanding video game for about 20 minutes.
As another comparison, In the USA alone around 12,000 GWh of energy is spent in burning gasoline in vehicles every single day. So Americans driving 1% less for a single day would save more energy than creating GPT4 and the world using it for a year.
