Humanity is just now beginning to realize that the real problem of running out of oil is not its value as a fuel, but rather, its value in creating plastics. Because of this, we're just now starting to see major research in using bacteria and other life forms to create bioplastics.
Perhaps the aliens came to this conclusion sooner, and use bioplastics almost exclusively.
That is neither truly militarily sensitive nor is it trivial.
