(CSRwire) SAN FRANCISCO, CA - April 19, 2007 - The Center for Resource Solutions (CRS) announced today that Alliant Energy’s Second Nature product is Green-e certified and available to customers of Wisconsin Power and Light Company. Wisconsin Power and Light Company is a part of the largest network of renewable energy providers who offer products certified by the nation’s leading certification and verification program. The Second Nature renewable product offered by Alliant Energy through the Interstate Power and Light Company in Iowa and Minnesota has been Green-e certified since 2004.

"The availability of Green-e certified Second Nature to customers of Wisconsin Power and Light Company in addition to customers in Iowa and Minnesota enables even more people to improve the environment by buying renewable energy," said Lars Kvale, an analyst with the Center for Resource Solutions. "To benefit local economic development, the program supports local generation sources of renewable energy."

The renewable energy available to consumers through Alliant Energy's Second Nature program comes from renewable energy sources located in Iowa, Minnesota and Wisconsin. Alliant Energy's Second Nature program allows customers to purchase renewable energy from wind farms, biogas energy from a landfill, and solar energy from a photovoltaic installation. This renewable energy displaces energy produced by more traditional sources such as coal and natural gas, resulting in cleaner air and improving the health of the community.

"We're very pleased to add our Second Nature program in Wisconsin to the Green-e status," said Janice Mathis, product manager, Second Nature. "As the early adopters of renewable energy, all of our Second Nature customers now have the assurance that the renewable energy we purchase on their behalf meets the high standards established by CRS. We hope this achievement motivates more of our customers to join Second Nature and take advantage of the opportunity to reduce their carbon dioxide impact."

The Green-e program is the leading renewable energy certification and verification program in the U.S., with over 150 participating vendors who sold over five million MWhs of renewable energy in 2005. The program provides independent, third party certification to ensure certified renewable energy meets strict environmental and consumer protection standards.

Through the display and recognition of the Green-e logo, the national symbol for renewable energy excellence, a growing number of consumers are able to easily identify high quality, certified renewable energy options, as well as everyday consumer products that are produced by companies who use renewable energy in their operations.

Providers of Green-e certified renewable energy agree to abide by the Green-e Code of Conduct, and meet strict Green-e disclosure and truth-in-advertising requirements. All Green-e marketers undergo an annual verification audit to document that the company purchased or generated enough quantity and type of renewable energy to meet customer demand and marketing claims.
