A "tracer bullet" is a resource guide to a certain subject, and the Library of Congress website maintains a large number of them. One of their recent offerings is on wind power. It's a lengthy list of recent, reliable, and definitive information sources, from introductory material to technical reports.
The number of topics they have tracer bullets on is impressive. This is the list of those just in the science category. (You do want to take note of the dates of each, however. For example, the 1989 tracer bullet on "Halocarbons and the Stratospheric Ozone Layer" is now outdated.)
