Hmm...maybe you should have started working on it when it was assigned. The reason for this project is to teach you how to study using dictionaries, encyclopedias and the Internet. YA is not here to spoon-feed your answers to your homework! With all the talk about energy sources on the news in the last few years, you should have some inkling of what it's all about. So...take your lumps and admit to the teacher that you didn't do the work.
