Those are great examples of what I'm talking about. They may not run on gas or diesel but their existence still required oil.
Oil was used to manufacture them.
Every piece of plastic and rubber contains oil
Hydraulic fluid = oil
They may not pollute but petroleum is still very much required. What do we do with the left over portion of the oil that we used to use for energy?
