This On The Radio segment discusses how Alliant Energy recently added Cedar Rapids to its list of Iowa cities moving away from coal and toward natural gas.
Transcript: Alliant Energy began burning natural gas instead of coal in one of its largest energy units in Cedar Rapids last month.
This is the Iowa Environmental Focus.
Crews converted one of four coal-burning units at Prairie Creek Generation Station so that it could operate using natural gas last month. Upgrades to the more than 100 megawatt unit are expected to reduce the plant’s carbon dioxide emissions by 25 percent and sulfur dioxide, mercury, and particulate matter pollution by 50 percent.
Alliant Energy has also recently transitioned from coal to natural gas at plants in Marshalltown, Dubuque, Council Bluffs, Bettendorf and Clinton. Prairie Creek Generation Station is expected to be coal free by 2025.
While coal still provides 47 percent of Iowa’s energy, that number has decreased significantly in recent years. Wind energy provides the second largest percentage of Iowa’s electricity, making up 36.6 percent of the total energy picture.
