Well, I think I probably, if you ask me, which one of those factors is probably the gating item from a project perspective, I would say it's probably PPAs that would be the issue that is driving a project. As you know, Lord knows, there is lots of land, particularly in the Midwest, where the wind resources are strong and certainly, I think, a fair degree of clarity to the permitting guidelines. So it's access to PPAs. In terms of but helping that. So I was hoping the opportunity for PPAs and I guess we are actually on both sides of this analysis is when you look at the ability to have the U.S. treasury effectively subsidize the price of power through the PTCs, it's hard not to think that it would be prudent as a utility, to the extent that you need more energy to satisfy retirements in the coal space or other forms of generation that you should be taking advantage of some of that $20 or $25 power which is available right now from the wind industry. So I think we are hopeful that those forces continue to encourage utilities such as Northern States Power who's the offtaker for Odell, from our perspective or Wolverine, who is the offtaker for Deerfield to take advantage of the full value of the PTCs. As you are aware, Rupert, they kind of stepped down. It's a five-year goodbye to the PTCs, but this year you can harness 100% of those PTCs and so we are seeing lots of activity. People are considering it. We are thinking about it ourselves as we think about Empire. As, you know Empire is bringing 1400 megawatt worth of generation to mix, a lot of it which is coal. And so the question is, should Empire be thinking about taking advantage of this by taking advantage of the ability to get 100% of the PTCs. So we are active in the marketplace. I think the permitting environment, certainly the appetite for yield and therefore cost of capital, t the availability of tax, actually they are all positive contributors which are the basis for my statement, Rupert, that there is a fair number of tailwinds, pardon the pun, to the development environment in the U.S.
