[5] MidAmerican Energy Company owns and operates 5 coal plants in the state of Iowa, including units in Salix (near Sioux City), Ottumwa, Louisa, Council Bluffs.

These plants are responsible for one-third of Iowa's industrial CO2 Emissions[6] and have been found to have led to 3,700 premature deaths in the U.S. as a result of particulate matter pollution.

[7] The Clean Up MidAm Coalition was launched in 2022 to shed light on the health and climate change impacts of these coal plants.

In June 2016 MAE signed up for 2 GW in Iowa (Wind XI) supplied by Vestas in Colorado, estimated at $2.2 billion.

On July 26, 2016, MAE agreed to supply power to Facebook, Microsoft and Google datacenters in Iowa from Wind XI.

Wind XII will make MidAmerican the first investor-owned electric utility in the United States to generate renewable energy equal to 100% of its customers usage each year.
