 My name is Alexandra File. I'm currently with the EPA and we're representing Energy Star today. Energy Star is a government-backed program fortified by the EPA and DOE and we work to certify products to be energy efficient. And energy saving, we work with homes, industries, commercial buildings and we work to just make a more energy efficient sustainable future and protect our environment of course. Well energy efficiency is really important because it's one of the simplest ways that people can save energy and also money and especially with sustainability these days I personally believe that helping people if we can convince them that they can save money then we can all work kind of towards a sustainable future and energy efficiency is a really great way to achieve that.
