How can we rule out whole classes of dark energy models? And what quantities,
at what redshift, and with what accuracy, should be measured in order to rule
out these classes of models? I present answers to these questions by
discussing an approach that utilizes the principal component parametrization
of dark energy. I show results based on current data, and future forecasted
data from a space-based dark energy mission and Planck. Finally, using the
same basic framework I present a quantitative analysis motivated by recent
claims that the number of high-redshift, high-mass galaxy clusters is in
disagreement with the standard cosmological model predictions.
