Cedar Rapids Gazette: Alliant Energy is seeking to have net-zero carbon emissions by 2050, along with the elimination of coal from its facilities by 2040, the company announced in its corporate responsibility report. It doesn’t necessarily mean Alliant is aiming to stop all use of fossil fuels by 2050, said Jeff Hanson, director of environmental services and corporate sustainability for Alliant. “There still may be some fossil-based generation — natural gas generation most likely,” Hanson said. “But any CO2 emissions that are released by those sites would be offset.”
