Why is gas prices going back up?

For the most part, our gas prices do not follow any sort of documented pattern. While it has been great watching prices plummet over these past couple of months, this has less to do with demand, or supply because OPEC is a protected cartel. They set the price and we pay it, or go without gas. The problem, however, is when they keep the price high people start talking about alternative sources of energy ect, like we saw during the election. This is bad for them because they rely on our dependency for oil. Consequently they begin to lower the price, but that's not to say they won't raise it again once they feel our memories have been erased, ect.
