1. RENEWABLE ENERGY
A Texas-sized debate over wind farms and military readiness
Since the mid-1960s, pilots at Sheppard Air Force Base have made supersonic training flights over the Texas Red River Valley, a region sufficiently remote that mostly cattle ranchers and oil riggers caught sight of the small planes known as "white rockets" as they streaked across the horizon. But as wind energy gains a larger foothold in North Texas, some say the region's long association with military training is being compromised.
