Second Nature

You'll make a world of difference

Second Nature™ is a voluntary program that allows Alliant Energy residential and business electric customers in Iowa, Minnesota and Wisconsin to support electricity generated from renewable resources. There is no special equipment to buy and no lifestyle changes needed.

Currently nearly 15,000 residential and business customers in Iowa, Minnesota and Wisconsin contribute to the purchase of renewable energy.

Second Nature offers residential electric* customers* three participation levels: 25 percent, 50 percent or 100 percent of their monthly electric usage. Based on the average customer’s use of 1,021 kilowatt-hours of electricity per month, participation at the 25 percent level costs just 17 cents per day, or about $5.10 per month.

Farm, small business or commercial/industrial electric customers of Alliant Energy who join Second Nature pay a monthly contribution which covers the added expense of harvesting the wind, solar and biomass energy used in the program.

To enroll or change your participation level call 1-800-ALLIANT or email secondnature@alliantenergy.com and request an enrollment card.  You may also enroll online by completing the appropriate enrollment form – residential or non-residential.

The Second Nature program is Green-e® Energy certified. Green-e Energy was established by the non-profit Center for Resource Solutions to provide information and an objective standard for consumers to compare renewable energy options, and to verify that consumers get what they pay for. For more information on Green-e Energy certification requirements, call 1-888-63-GREEN or log on to www.green-e.org.
