Think of us today as embarking on a new Thirty Years’ War. It may not result in as much bloodshed as that of the 1600s, though bloodshed there will be, but it will prove no less momentous for the future of the planet. Over the coming decades, we will be embroiled at a global level in a succeed-or-perish contest among the major forms of energy, the corporations which supply them, and the countries that run on them. The question will be: Which will dominate the world’s energy supply in the second half of the twenty-first century? The winners will determine how -- and how badly -- we live, work, and play in those not-so-distant decades, and will profit enormously as a result. The losers will be cast aside and dismembered.
