To be a Giffen good, energy consumption would have to rise when the price increases. Inelastic demand is not enough: elasticity must be negative.

Bus tickets should be a Giffen good. As the price of oil increases, demand for bus services goes up, in spite of the increasing bus fuel surcharges.

Peak oil is not an energy crisis. It is a liquid fuel crisis.
