Extremely useful tool By European Environment Agency

RETScreen is a very useful tool, covering all renewable energy types, and energy efficiency. It allows you to quickly interpret the main opportunities, as well as providing LCA and financing information. The textbook is also of an extremely high quality. For a freely available tool it's hard to fault; my only criticism would be that it needs MS Excel in order to work, though I understand that will be addressed in future releases.
