History may judge Cape Cod renewable-energy initiatives sooner than many expected. Although the proposed Nantucket Sound wind farm is the most prominent example of conflict between history and renewable-energy efforts, less well-known projects face scrutiny from historic preservation advocates across the Cape.

In a packed Town Hall auditorium, the continued public hearing on the proposed twin wind turbine project off Route 3A began to give residents a better picture of the breadth and impact of the project. The nearly three-hour meeting was a mix of technical information, questions and answers and airing of resident concerns. The 100-plus audience was well informed and it was clear through many of the comments made residents had done their research on turbines. Dozens spoke on myriad concerns from noise to shadow flicker to the impact on property values.

In yet another congressional maneuver that could kill a wind farm proposed off Cape Cod, a conference committee is considering language that would prohibit wind turbines within 1.5 miles of shipping and ferry lanes.
