Renewable energy engineering jobs?

My ambition is to be an engineer in the renewable energy field . I'm sixteen now and once I get my degree I suppose I have to get a job. The question is what job could I get? I want the job where I have to innovate the technology and do projects but I don't know what is that job called. They have all these project engineer, and so on but which is the one where I can innovate and get a fairly high pay ? And plus can I get such a job as a first job with a simple degree? If not , what should I do? Thanks , I appreciate your help . If you are willing to help can you (experienced person) give me your email in the answer so I can ask you more ? :)
