From the blog formerly known as Green, Inc.:
Even if the United States takes no explicit action to regulate greenhouse gases, emissions of carbon dioxide and other climate-altering substances will grow slowly over the next two decades, not returning to 2005 levels until 2027, according to a new projection from the Energy Information Administration, the research branch of the Energy Department.
Carbon dioxide emissions fell by 3 percent in 2008 and 7 percent in 2009, largely because of the recession. But even as economic activity picks up, emissions will grow at a modest pace because of growing use of renewable technologies and fuels, improved energy efficiency, slower growth in demand for electricity and the growing substitution of natural gas for coal in power production, the agency reports in its annual energy outlook.
