Well, here might be another un-forseen problem with wind energy...

As of 2008, wind turbines had compromised almost 40 percent of U.S. long-range radar systems(h/t [URL="http://masterresource.org/"]masterresource.org

The base and a county airport land-use body sought to have the projects delayed until turbines’ effects on radars could be further studied. But when, the following year, a project supporter donated $1 million to the base, Col. Steven Arquiette, commander of the 60th Air Mobility Wing at Travis Air Force Base, “was told by his superiors to accept the money and withdraw his complaints,”according to Masterresource.org blogger Lisa Linowes, despite the fact that nothing about the plans had changed substantially.
Now pilots coming in to Travis are urged to turn on their aircraft’s transponders as a way of announcing their presence, since they still cannot be seen on radar. This poses a sizeable security threat given that it could easily be emulated by terrorists – and has been. As Linowes notes, among the first actions the Sept. 11 perpetrators did was turn off the transponders of the planes they hijacked.
Wind farms have also dramatically slowed the Federal Aviation Administration’s review time for project proposals. While it once took a month for construction of a project to be approved or be declared hazardous, now similar projects stand to wait up to three times that long.
