The NY Times has a story about federal approval of some Midwestern wind-power transmission lines, which shows how long and powerful they are – think Northern Pass times three or four. I’ve swiped their map above, which makes our massive proposal look kind of small.
Of course, if the towers are near your house, they don’t look terribly small. They’ll be about the size of the Midwestern towers, so the individual components won’t be much different.
