Two centuries ago William Blake said with some prescience, “Energy is spirit, and the spirit is within us. ”
You ask: What can history teach us about energy? It can teach us that inattention to its problems contributed to the fall of civilizations. Plato describes in Critias how Attica had already become ”… a mere relic of the original country … all the rich, soft soil has moulted away, leaving a country of skin and bones.” The Greeks (and the Romans, Carthaginians, and so on) cut down their trees for firewood and made barren much of the Mediterranean littoral. In North Africa (the ancient granary of Rome) the Arab is not only the child of the desert but also in part its father.
How did we get into our present troubles? Bit by bit. Beyond absurdity, this is stuff for the theater of the bizarre. It is not so much a question of villainy as of myopia.
