First of all: please don't mix in other mods in this discussion. Yes I know many ppl use RP out there but in the end fixing things by adding another mod does not fix the initial problem it just hides it.
A well placed wind mill does not break and outputs around 1.5 EU average (even more if you build higher). You need about 150 cables to wire the stuff down, which is about 38 iron (not that much) and 450 rubber (which is much but a renewable resource). So the con breaks down to: you need lots of rubber.
On the other comment: I don't think you can count in player death in this one, as for once it is the player's own fault not to press the shift button and for second you don't really loose any resources through dieing unless you do something stupid, in which case it is the player's fault again. I as well don't find it very complicated to place the wire, all you need is jumping and repeatedly pressing the left mouse button.
A solar generator outputs about 0.5 EU/t on average, actually slightly less if you calculate the rain time into that.
Beside that they are currently broken and therefore sometimes just won't work at all, they output 0.5 EU/t (considering that you get 2). Compared to the additional iron cost for wind generators, you get for the cost of a wind mill about 0.75 EU/t through water generators.
In general that means that the wind mill currently has the least disadvantages (you need lots of rubber) while having the highest average EU output (twice as much as water, 3 times as much as solar). If all those green generators are supposed to be about equal, wind mill energy needs to be cut in half.
