Abstract: Recent cosmological data has revealed that around 70% of the universe is made up of some mysterious dark energy, which is causing the rate of expansion to accelerate. But the underlying cause of this acceleration remains unknown. The next generation of cosmological surveys will provide us with far greater constraints on the dark energy parameters and allow us to choose between different possible models. Given the large investment such experiments require, it is important to design such experiments to give the greatest scientific return. In this talk I will outline the methods of probing the dark energy, the next generation of surveys that will do so, and techniques of optimizing such surveys. As an example I will discuss a proposed next generation experiment designed to probe the dark energy through measurements of the Baryon Acoustic Oscillations.
