A pejorative term often used to describe the supermajor non-state owned oil and gas companies. Expressions are often used about “being in the pocket of big oil”.

A vehicle with two separate fuel systems designed to run on either fuel, using only one fuel at a time. A vehicle that employs a combustion engine system together with an electric propulsion system.

Dedicated natural gas vehicles are designed to run on natural gas only, while dual-fuel or bi-fuel vehicles can also run on gasoline or diesel. Dual-fuel vehicles allow users to take advantage of the wide-spread availability of gasoline or diesel but use a cleaner, more economical alternative when natural gas is available. Since natural gas is stored in high-pressure fuel tanks, dual-fuel vehicles require two separate fueling systems, which take up passenger/cargo space.
