Characterizing the nature of the dark energy that dominates the matter density of the universe is a profound challenge for observational cosmology. Several approaches to investigate dark energy are in progress, or have been proposed; these include include traditional ground and space-based supernovae surveys, weak lensing surveys, characterization of the galaxy power spectrum on large angular scales and at high redshifts, characterization of galaxy clusters at high redshift, as well as the ongoing role of cosmic microwave background investigations.

The workshop will focus sharply on how the diverse approaches to characterizing dark energy may be best deployed to make progress over the next decade. A portion of the discussion will be concerned with the near term prospects of programs now or soon likely to be underway, followed by an examination of how more long-ranged space probes or large ground-based telescopes may best build on this work.
