Thank you, Mr. Chair. I'd like to thank our witnesses here today for their expertise.
Based on what Mr. Seymour said, one of the challenges that we have to recognize is that when you have an inventory of buildings, some of them are very old. You have programs like the FBI, which has been steadily retrofitting these over a period of time. You'll start to see marginal returns, where it will be more and more difficult to be able to put the same amount of dollars to get the same amount of energy efficiencies, because you've already fixed all the low-hanging fruit. That being said, it's a program that I'm very supportive of and I hope it continues. In fact, I think taxpayers expect us to find reasonable savings where we can.
Mr. Carpenter, you mentioned a wider argument or discussion of energy efficiency. The federal government has a large number of buildings, both leased and owned, throughout this great country. In some cases, some regions rely more on carbon-based fuel or energy production, and some rely more on non-carbon-based energy production. Is that something that should be factored into it? Say you have one building on the west coast utilizing energy derived from hydroelectric generation and you have another building elsewhere in the country utilizing energy from coal-based production, if you have limited resources, is it not wise for us to consider where we can get the best bang for our buck, given limited resources? I'd like your thoughts on that.
