Powering a Clean Energy Future

More than 10% of our energy comes from renewable sources.

Wind
We own and purchase enough wind power for more than 155,000 homes. In July 2016, we announced our plans to invest approximately $1 billion to expand our Whispering Willow Wind Farm in Franklin County, Iowa, and to potentially develop other sites. The five-year project will add up to 500 megawatts of clean energy to meet our customers' needs.

Solar
We are building two solar learning and demonstration projects and as well as new solar generating facilities.

Carbon dioxide reduction
Since 2005, we’ve reduced carbon dioxide emissions by 22%. We are targeting reducing carbon dioxide emissions by 40% by 2030. View our Corporate Sustainability Report for additional information.

Customer-owned generation
Alliant Energy has helped more than 1,650 customers connect their renewable (often solar) systems to the electric system.

Second Nature (TM)
More than 13,000 customers use our Second Nature program to offset their energy usage with renewable energy sources.

Hydro (Water)
Alliant Energy owns and/or operates hydroelectric facilities that can power roughly 42,000 homes.

Anaerobic Digesters
Six dairy operations in our service area have 4.7 megawatts of generating capacity.
