Thats one of those things this film gets into, these unconventional energy sources like shale and shit is not efficient or cost effective, like at all, and it wont sustain us for long. I think its only a short matter of time before we have to invest heavily in alternatives, and we need to be sensicle about our power useges because even alternative energy sources have their drawbacks

I have learnt a good amount so far about conserving energy by living off grid, it really is not all that bad and I dont even know how to make the power work yet haha.
