There are many to choose from, including:

Pick one of these forms of energy or research another one of your choice. Write a report telling about the advantages and disadvantages for each form of energy. How clean is it? How sustainable is it? What are the risks? What are the side effects?
Write a detailed report and at the end of your report, tell whether or not you think this form of alternative energy is a good source of energy for our future.
