The problem with talking about the costs of energy is that we rarely look at all the costs. What about the massive government subsidies for fossil fuels? How much treasure and blood did we spend in the Middle East to ensure access to cheap oil? What about the costs to the environment? The costs for treating asthma and other diseases due to air pollution? 

A well-run company (or country) would also factor in these costs, not simply what is paid at the pump.
