If Trump is wrong about American military dominance, then perhaps he’s also wrong about what he calls American energy dominance. His Administration has long promised to “unleash” American oil; last week, his Energy Secretary, the former fracking executive Chris Wright, used the Iran war to explain why BP would be allowed to drill in the deep waters of the Gulf of Mexico. “At a time when Iran and its terrorist proxies attempt to disrupt the global energy supply, the Trump Administration remains committed to strengthening American energy dominance,” Wright said. But America’s fossil-fuel machine should be ready to face an inexpensive upstart technology, too. What if the drone is to warfare as the solar panel is to energy?
