By supporting renewable energy through Second Nature, your business can:

  • Demonstrate a leadership role in your industry.
  • Gain a competitive edge.
  • Add value to your brand and generate positive publicity.
  • Promote socially responsible business practices and consumer health.
  • Join Alliant Energy's other business green energy buyers.

How does Second Nature work?

  • 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.
