 Michael Cicchetti, I'm with Covanta. Covanta is an energy from waste company, so we take irregular household waste, and instead of it going into a landfill, we take it to our facilities and we can combust it and make electricity for it. So we're a domestic renewable energy source. It's a base load renewable energy. We run 24-7, 7 days a week, 365 days a year. We're also a greenhouse gas mitigation technology. For every ton of waste that we take at our facility, there's a corresponding one ton reduction in greenhouse gas emissions. And that's primarily from the avoidance of methane that would otherwise come from that waste if it was sent to a landfill. So we also recycle metals out of our process. For every ton of waste that we process, we get about 50 pounds of metals out of that process. So we're able to recycle those metals. Last year we recycled enough ferrous metal to build five Golden Gate bridges. So there is a lot of metal and trash that if it goes to a landfill, it's going forever. Whereas we can capture that metal and make sure it's recycled. Well I think from an overall perspective we've got to make sure we're reducing our reliance on foreign fuel sources, reducing our reliance on carbon-emitting fuels. So energy from waste is an important piece of that overall renewable policy. As I said, we're a base load renewable. We're not intermittent. So we are a good complement to other forms of renewables that may be more intermittent and based on weather. Or as I said, we run 24-7.
