The "true cost of energy " from the coal example is perfect example of why tax incentives & subsidies hurt us. If it takes more energy to move coal out of a mine than it generates then the mine will go out of business, that is unless the coal is used as an economical store of energy -- i.e. we use fuel to power our cars instead of nuclear because fuel is easy to move etc.
