According to this article, there is a new inflatable "blimp" turbine, which can produce a significant amount of cheap energy - low maintenance, fast setup. They envision it being used in small villages and military camps. I could see it being used by exploration groups - maybe even tethered on ships at sea? Of course they have their own water-driven generators. Of course it seems like a prime target for any attacks from militants and the like...but still!
