In a surprising turnaround, the amount of carbon dioxide being released into the atmosphere in the United States has fallen dramatically, to its lowest level in 20 years.There's more at the link. One of the interesting aspects of the story is how surprised almost everyone was that so many companies have switched over to natural gas so quickly and how much of a difference it has made in our air quality. I think there's a lesson in this. Business responds to the market. Fracking technology enabled gas to be produced abundantly and cheaply and business has responded without government having to obtrude with heavy-handed coercion.
Government officials say the biggest reason is that cheap and plentiful natural gas has led many power plant operators to switch from dirtier-burning coal.
Many of the world's leading climate scientists didn't see the drop coming, in large part because it happened as a result of market forces rather than direct government action against carbon dioxide, a greenhouse gas that traps heat in the atmosphere.
The International Energy Agency said the United States has cut carbon dioxide emissions more than any other country over the last six years. Total U.S. carbon emissions from energy consumption peaked at about 6 billion metric tons in 2007. Projections for this year are around 5.2 billion, and the 1990 figure was about 5 billion.
China's emissions were estimated to be about 9 billion tons in 2011, accounting for about 29 percent of the global total. The U.S. accounted for about 16 percent.
Market solutions to problems may not always be better than government-imposed solutions but they sure were in this case. Meanwhile, the Obama administration, still convinced that government knows best, continues to squander millions of taxpayers' dollars on wind and solar energy companies which are floundering because they can't produce a product cheaply enough to interest consumers.
