*infoman*, replacing pylons by putting electrical cables underground can be problematic. There are places where the geology, topography and sheer distance make it prohibitively expensive, but it is happening slowly... It happened over a short distance near us a few years back, but the trench for the cable went straight through known archaeology so there had to be an excavation in advance of the cable-laying - so another potential expense.
Another problem with putting electric cables underground is that it is apparently more difficult to find where any fault is in a long line of underground cables. On the other hand, I saw a report somewhere the other day about a dog which can smell out where a fault is, so there may be some hope yet!
I agree with those who say that they find the sight of wind turbines pleasing.
