Guided Tour on Wind Energy Welcome to your own guided tour on wind energy. Each one of the tours is a self-contained unit, so you may take the tours in any order. We suggest, however, that after the introduction you start with the first section on Wind Energy Resources, since it makes it much easier to understand the other sections.
