 My name is Carolyn Sloan and I'm the Director of Clean Air and Climate Policy at the Business Council for Sustainable Energy and we are a trade association made up of energy efficiency, natural gas, and renewable energy companies. We're a broad base so we represent everyone from utilities to independent power providers, energy service companies, manufacturers, so a wide range of clean energy services and technologies. We support any policies that drive the deployment of our clean energy technologies, so whether that is appropriations policies, clean energy tax credits, climate policies, anything that drives the use and widespread use of our clean energy technologies. So we love the Expo and we've been here I think every year since it started, one because we really love to support ESI, they're a really strong partner of ours. We also support our members who are also here exhibiting and it's a really great opportunity to network with other clean energy professionals to share the information that we have and that's mainly in the form of our Sustainable Energy in America Fact Book which we produce every year with Bloomberg New Energy Finance and as a broad look at the energy sector in the United States so it's a great opportunity to share that data, to network with other clean energy professionals and just have a good time with ESI.
