Where should I post for a very cool internship in renewable energy?

Is it for college students? If so,I’ve had the best luck recruiting interns from the career office of nearby universities. Or, emailing a professor in that field and seeing if s/he has students to recommend. Other good options include posting on Idealist.org and craiglist.org
Word of mouth is how I’ve gotten my best interns…circulate an email asking if anyone knows someone who fits the bill…

Yes, I would say it’s for college students. One wrinkle (benefit, actually) is that it’s in the Bahamas

ooooh, can i do it?

Where would you like for me to send my resume`?
