This leads to a longer-term question, but I have a little tiny bit, so I'll try to get some answers to this and maybe come back to it after.
I heard you talk about innovation and technology innovation, so we talked a little bit about research and development. We all know we have to get greener. How does the gas and oil world think about getting greener? How are we going to start doing that? Is there research and technology being put into that?
