Replying to Sources help for an analytical report

hey guys, if you're really bored and willing to help out a fellow NS-er i'd appreciate it.   I'm writing a paper on how alternative/renewable forms of energy will lead to lower oil prices and i'm trying to find sources that either directly or indirectly give evidence of that happening if the world uses renewable sources of energy.

and i know its pretty complex so i'm looking for indirect evidence that it would help to lower oil prices...so if you wouldn't mind trying to help me i'll throw you some karma, or some positive vibes or something.

thanks....
