I'm going to limit my answer to my area of responsibility, and that is to improve energy efficiency. I do have responsibility for the federal buildings initiative. It uses private sector financing to fund energy efficiency projects in federal buildings, which helps improve energy use and save energy. It's a fairly modest but successful program in terms of helping those projects take place.
I'd like to speak a little bit to the point you made about energy efficient or green ecological buildings costing a lot. We ran a program for eight years for new buildings where we subsidized the cost of the energy efficient design, in fact helping support the capacity in the economy for the LEED building assessments. Our program still does the assessment for LEED. We determined, over thousands of buildings, that the cost premium can be very small--it can be zero--and can be recovered very quickly.
So one of our objectives as the federal government is to try to get the information out there that sometimes to be green is not necessarily to be very much more expensive, and that certainly it will save energy over the life of the building.
