10 years ago, dark energy was discovered using luminosity
distance measurements of type Ia supernovae. Since then,
multiple programs have refined the cosmological constraints
with the addition of high redshift supernovae.
These observations are now at their systematics limit.
Fortunately, many of the largest systematics are addressable
through improved measurements of nearby supernovae.
In this talk I will describe the basics of using supernovae
for cosmology and the Nearby Supernova Factory,
a program to directly address the limiting systematics
through the observation and analysis of nearby supernovae.
Using this unique dataset, I will present new methods to
calibrate the luminosity distance of supernovae to
improve cosmological constraints.
