• Federal judge signals Defense Department violated law with wind-energy project review freeze.
• Freeze has disrupted project schedules and jeopardized $47 billion in investments.
• Defense Department halted reviews citing national security concerns over radar signal interference.
• Judge to issue written ruling soon.

The Defense Department's freeze on wind-energy project reviews may indicate a shift in national security priorities, which could have significant implications for the renewable energy industry. This move suggests that the department is reevaluating its assessment of risks and review process for such projects, which could lead to changes in the way wind energy projects are approved and implemented.
