The boom in natural gas production has undeniable benefits for the United States. But two policy analysts argue that embracing a monolithic energy future dominated by gas will mean the loss of a golden opportunity: Leveraging cheap, abundant gas to create a sustainable future based on renewable power. The United States has won the lottery on natural gas. According to the most recent estimates by the Energy Information Administration, the U.S. has some 2.2 trillion cubic feet of technically recoverable natural gas — enough to satisfy all of our natural gas demands for the next century at current consumption levels. The extraction of shale gas, enabled by technological advances such as hydrofracturing and horizontal drilling, has led the way in creating this largely unforeseen cornucopia. Domestic natural gas is now a cheaper fuel for electricity generation than coal — long our go-to fuel for power around the clock — and emits roughly half the greenhouse gas emissions. It appears that our energy problems are over — or are they?
