Second Nature™ for your business: How it works

Through Alliant Energy's innovative Second Nature™ program, businesses in Iowa, Minnesota and Wisconsin can support the growth of clean energy from wind, solar and biomass.

Here's how the process works:How Second Nature works

  • Your electric meter measures the kilowatt-hours your business uses each month. We divide this amount by your Second Nature contribution to determine the equivalent of green energy.
  • Next, we combine your usage with other Second Nature participants to get the month's total green requirement.
  • Then we make sure we're bringing enough new green energy into our energy pool to meet the total renewable energy requirement.
  • The additional green energy comes from new Second Nature sources, above and beyond Alliant Energy's standard generation portfolio.
  • That means every Second Nature customer directly increases demand for renewable energy and reduces demand for non-renewable energy.

To help you determine the amount of renewable energy your contribution supports, simply divide the monthly contribution amount of $.02. For example, a $50 monthly contribution allows us to buy 2,500 kilowatt-hours of renewable energy - the annual environmental impact of planting seven acres of trees or not driving more than 65,000 miles!
