I review the observational evidence for dark energy, arguing that the large-scale structure observed at low redshift and in the cosmic microwave background offers a strong corroboration of the supernova Ia results. The angular scale of the acoustic oscillations in the cosmic microwave background strongly support a nearly flat universe, while many arguments from low-redshift cosmology support a matter density around 25% of the critical density. The observational constraints on the cosmological model have improved dramatically over the past decade. The coming decade will likely bring another two to three orders of magnitude in improvements in the data sets used for the study of dark energy.
