Observations of distant supernovae have indicated that the universe in not only expanding, but that the rate of expansion is accelerating. This intriguing result has given birth to the theory that the universe is infused with a mysterious substance known as dark energy. The hunt is on to discover the properties of dark energy and discover amazing new physics in the process. One of the ways in which dark energy imprints its signature on the Universe is through its influence on the formation of structure such as galaxies, groups and clusters.

In this talk I will review the basics of dark energy and present recent results from N-Body simulations studying the effects of dark energy on structure formation.
