And it is still true, wind will be never be able to compete with nuclear for the simple fact that wind blows when it blows and you need energy when you need it. Unless we develop a technology that is able to cope with the huge spikes that windmills put on the energy grid and store energy in a very efficient way (including gaining the energy back when we need it) wind will not be more than few percentage of the overall energy production with the cost of having gas turbines in the system to just to balance windmills. Solar is obviously far better, there are few things to sort out but the progress we made is definitely promising.
