[H]ere’s the thing: the next president won’t need to pass comprehensive legislation, or indeed any legislation, to take a big step toward saving the planet. Dramatic progress in energy technology has put us in a position where executive action — action that relies on existing law — can achieve great things. All we need is an executive willing to take that action, and a Supreme Court that won’t stand in its way. ...
[T]he cost of electricity generated by wind and sun has dropped dramatically, while costs of storage, crucial to making renewables fully competitive with conventional energy, are plunging as we speak.
The result is that we’re only a few years from a world in which carbon-neutral sources of energy could replace much of our consumption of fossil fuels at quite modest cost. True, Republicans still robotically repeat that any attempt to limit emissions would “destroy the economy.” But at this point such assertions are absurd. As both a technical matter and an economic one, drastic reductions in emissions would, in fact, be quite easy to achieve. All it would take to push us across the line would be moderately pro-environment policies.
As a card-carrying economist, I am obliged to say that it would be best if these policies took the form of a comprehensive system like cap and trade or carbon taxes, which would provide incentives to reduce emissions all across the economy. But something like the Obama administration’s Clean Power Plan, which would use flexible regulations imposed by the Environmental Protection Agency on major emitters, should be enough to get us a long way toward the goal.
