What degree should I look into for clean energy?

I want to have a profession in the clean energy field. I have an interest in chemistry and want to research new possibilities or possibly use that knowledge to make alternate energy sources we have now, possibly less expensive, more available, and more popular with most people. I don't know where to start my search though. I'm a senior in high school. It's crunch time, I have to decide what schools I wish to go to and what to study, and finish applying to academic scholarships. Any advice is greatly appreciated.
