John Sununu, writing in the Boston Globe, observes that the free market has improved energy efficiency:
Today, the economy uses 40 percent less energy than in 1980 to produce a dollar of goods. Government did not create the shale gas boom. Government did not turn North Dakota's once languishing Bakken oil fields into one of the country's largest. (North Dakota now produces more oil than Alaska.) Government did not subsidize the rigs, provide tax credits for the refineries, or chant "drill, baby, drill." And with natural gas consumption up and coal consumption down, emissions of carbon dioxide have fallen 15 percent below peak levels of 2007. As a more policy-minded Grinch might say: "It came without taxes, it came without bans . . . it came without protocols, mandates, or plans."
