The plunge in oil prices may be good for consumers and the global economy, but it could also hurt efforts to make our planet's energy system more sustainable. Policy makers from around the world can prevent this by taking advantage of cheaper oil to make meaningful changes in the way we price energy.
Perhaps those claiming that the U.S. may one day be energy-independent will be proven right. Perhaps as tight oil production begins to wind down, other alternatives will be found in sufficient quantities (and at an affordable price) to make up the difference, and the U.S. economy will continue growing. Perhaps.
