Thank you, Chair, and thank you to our witnesses for being here today.
Mr. Gilleland, I'd like to start with you because you've posed some very interesting thoughts with respect to where the Bill and Melinda Gates Foundation is going on this, as well as your company.
You indicated the study started in 2006. One of the things you went over very quickly, though, was the idea that renewables, in your conclusion, based on your studies, would be insufficient. What led to your conclusion that straight renewables that we know of today—I assume you mean wind energy and other things—would not be sufficient?
