Yes, I'll tell you what I mean by that.
I'll tell you that the single biggest factor is I truly believe, as many people do from all walks of life, that we waste a huge amount of energy today. I've been guilty of it too until recently. I already indicated one change I've made in my lifestyle. I truly believe I could give you a ballpark number--you can make up your own--but I think the easiest, the most cost-effective, the quickest ways in which we are going to meet our targets is through energy efficiency and energy conservation, not incredibly bold new technologies that replace what we're doing now.
