The beaming angle is the main uncertainty in gamma ray burst energy requirements today. We summarize predictions for the light curves of beamed bursts, and model the R band light curve of GRB 970508 to derive . This yields an irreducible minimum energy requirement of ergs to power the afterglow alone.
