Its been awhile since I watched it, but there are many examples. I'll go through a few below.
1) It tries to make it sound like grid tied solar is bad simply because it doesn't completely eliminate fossil emissions. Just decreasing emissions apparently isn't enough. Renewables have to completely eliminate fossil fuels. That's just not realistic.
2) The solar technology it talks about is probably 20 years old. Modern solar is much more efficient to produce, especially as we start to move towards thin film solar panels. Current solar panels produce over 20x the energy needed to produce them over the course of their advertised life span, after which they are still able to generate lots of energy, just at a slightly reduced rate. So basically, it only takes about a year for a modern solar panel to pay back its production energy.
3) For electric cars, it bases its argument on the worst case scenarios (and old data at that) for grid electricity generation. Michigan has an extremely dirty power supply, but even theirs is getting better. Move that electric car to a state with a cleaner energy grid, and the picture gets much better.
Basically, Moore is trying to argue that since renewables aren't perfect, they just aren't worth doing. I agree with part of the message, that a focus on decreasing consumption is also important, but renewables are a promising way to mitigate our impacts. They aren't going to eliminate fossil fuel emissions immediately, but they can help.
