Need to consider transportation fuel sector separately
Dr. Mackay has done an excellent job at a high level of assessing the possibilities for the world's future energy availability. In particular, I like his assessment of the limitation of land for biofuels and the need to go to breeder reactors if we are to use nuclear.
He has, however, made one assumption about the fungibility of energy. Until we have batteries which can efficiently and economically store energy for transportation, we need to consider the need for liquid transportation fuel (hydrogen has a need for new infrastractures and storage.and I think is a poor bet.
And so I feel the world should be looking for the interim solution of coal-to-liquid to augment oil and serve to keep price under control. Let's stop using coal for electric generation over the next several decades and use it for transportation - until we either have batteries, the algae process is developed or somebody figures out how to use solar energy, air and water to make liquid fuel.
