• Current cosmological observations strongly suggest that the present universe is undergoing a period of accelerated expansion. Many models have been proposed to account for the present cosmic acceleration such as postulating an enigmatic component called dark energy, modifying gravity to behave differently from general relativity on large scales and so on. In this talk, we review some of these models and their current status. Current observational constraints on the nature of dark energy are also briefly discussed.
