The Arizona Solar Center is not currently hiring. However, I suggest you consult the following internet site: http://wire0.ises.org/. They have jobs posted in the solar energy area. Our own internet site has many links to sources of information on renewable energy. Internships are possibly available from individual companies. I suggest you contact them directly. There are many internship programs that you should be able to find on the internet. Among them is the Environment and Energy Study Institute in Washington, D.C. Their telephone number is 202-628-1400.
Good luck.
