Certain regions such as the Midwest/Mid-Atlantic, Southwest/Rockies, and Northern Plains—regions that are home to much of U.S. coal production—tend to have greater reliance on coal-fired electricity generation. These regions have among the highest CO2 reduction requirements and are expected to have the largest shifts in their generation mix. In the Midwest/Mid-Atlantic region, a large decline in coal generation is offset by an increase in natural gas generation and relatively modest growth in renewable generation. These projected changes are expected to result in a 26% decline in the Midwest / Mid-Atlantic region's emission rate—from 1,826 to 1,357 pounds of CO2 per megawatthour, the largest drop of any region in both percentage and absolute terms. <a href="http://www.eia.gov/todayinenergy/detail.cfm?id=26712" rel="nofollow">www.eia.gov/todayinenergy/detail.cfm?id=26712</a>
