In the mid-Atlantic, there has been a lot of move to protest a Liquid Natural Gas exporting facility at Cove Point, MD. It seems to me that the big effort to stop that began right after Putin took over the Crimea and began the rebellion in the Ukraine with threats to cut off their fuel for the winter. The push was especially strong with certain very far left groups there, although they got a little distracted with Ferguson.
