Operational and near-future astronomical surveys of the galaxy distribution will soon put to the test our best ideas as to the nature of the current cosmic acceleration. I will briefly review the status of some of the most interesting proposals and then focus on LSS probes. The perturbative treatment of LSS can well describe the quasi-linear regime of structure formation. This regime is a precious repository of key information on both early and late-time Universe dynamics. I will elaborate on recent progress towards including a dark energy and a modified gravity component in this framework.
