In this paper, we investigate the energy conditions (including null, weak, strong, dominant) in generalized teleparallel gravities including pure F (T ), teleparallel gravity with non-minimally coupled scalar field and F (T ) with non-minimally coupled scalar field models. In particular, we apply them to Friedmann-Robertson-Walker (FRW) cosmology and obtain some corresponding results. Using two specific phenomenological forms of F (T ), we show that some of the energy conditions are violated.
