Not necessarily. With oil, more energy is generated than is put into its production. This is known as EROEI (Energy Returned On Energy Invested), which is how many units of energy are produced, for every 1 unit of energy put into its production. Oil is used to produce oil, and in the beginning oil had an EROEI of 100:1, meaning it took 1 unit of energy to produce 100 more. Today, its now like 30:1. If it ever reaches 1:1, it's no longer a resource.
