Like whale blubber, oil as a dominant source of energy will gradually be phased out over the next decades. Here's what that transition may look like.

While the push to reduce carbon dioxide emissions is spurring alternatives to petroleum in other sectors, phasing out plastic, particularly for medical applications, will be very tough.

We may never run out of oil, though known reserves are expected to last for about 50 years, current estimates suggest.
