I will start reviewing one of the main open questions in physics: why the expansion of the Universe is accelerating? Making precise maps of the structures of the Universe, as a function of time, can help us answer this question. I will present how we can learn about dark energy from these maps, in particular focusing on the state-of-the-art results from the extended Baryon Oscillation Spectroscopic Survey (eBOSS), published in 2020. I will finish by exposing the goals of next-generation surveys of our cosmic structures.
