Ok kiddo, let's talk about a big competition where people from all over the world try to guess how much energy we're going to use in the future.
So, you know how we use things like electricity and gas to make our houses warm and bright, and to power things like cars and computers? Well, a lot of really smart people are trying to figure out how much of these things we might use in the future, so that companies and governments can plan for it.
The global energy forecasting competition gives these smart people a chance to show off their predicting skills. They use math and data and fancy computer programs to make their best guess about how much energy we'll need in the future.
Then, all the guesses are compared to see which one was the most accurate. The person who gets closest to the actual amount gets a prize and a lot of recognition for being really good at guessing.
So basically, it's like a big contest to see who can guess the best about how much energy we'll need in the future. And the winner gets to be really famous and maybe even help make important decisions about energy use.
