Alliant Energy, corporate parent of Interstate Power and Light in Cedar Rapids, has set a new target for slashing carbon dioxide emissions by 40 percent over a 25-year period, from 2005 levels to 2030.

The Madison, Wis.-based utility holding company details steps it is taking to achieve its goals as well as progress it has made in an annual corporate sustainability report. The full report is available online at

Alliant Energy’s carbon dioxide emissions are declining as the company shifts from coal-fired power plants to natural-gas fired generation and more renewable energy.

“Alliant Energy has been taking actions for many years to reduce emissions and this carbon dioxide target is consistent with the clean energy path we’ve been following,” Patricia Kampling, Alliant Energy chairwoman, president and CEO, said in a news release.

The report shows Alliant Energy plans to reduce emissions of sulfur dioxide and mercury by 90 percent from 2005 levels by 2020 and nitrogen oxide emissions by 80 percent by the same year.

Alliant Energy already has cut sulfur dioxide and nitrogen oxides by 68 percent from 2005 levels, according to the report. Mercury emissions have been reduced by 70 percent and carbon dioxide reductions are at 22 percent.

Through 2015, Alliant Energy had reduced coal-fired generation by 30 percent. The company also has enough wind generation to provide electricity for 300,000 homes.

On July 27, Alliant Energy announced plans to invest $1 billion in wind generation to add 500 megawatts of renewable energy. A majority of the investment will be used to expand the utility’s Whispering Willow Wind Farm in Franklin County.

Alliant Energy plans to add 1,350 of natural-gas fired generation, 1,000 megawatts of wind generation and more than 8 megawatts of solar power generation.

The utility has funded a solar energy system at the Indian Creek Nature Center’s Amazing Space sustainable building that will produce 105 kilowatts of electricity. It will be Alliant Energy’s first solar power system that connects to the power grid.
