In the following video, Motley Fool energy analysts Joel South and Taylor Muckerman discuss a theory that has been around for 40 years -- the idea of peak oil. Joel tells investors that this won't mean that we run out of oil completely; rather, it means the end of oil that is cheap to produce, as resources that are easily accessed begin to dwindle. He then gives investors a few possible long-term plays to make to capitalize on this trend.
