Wisconsin Electric Power Co's green pricing Energy for Tomorrow (EFT) program is helping to fund the installation of small-scale wind and solar projects at the Milwaukee zoo, along with three environmental centres for students. Two Bergey turbines are involved. The exhibits have been installed at Kroehler Homestead Nature Preserve, the Schlitz Audubon Nature Center and the Havenwoods Environmental Awareness Center. EFT has 11,200 customers, who can choose to buy 100%, 50% or 25% of their electricity from renewable resources at a cost of $0.02/kWh, $0.01/ kWh or $0.005/kWh, respectively. Today, those resources include small hydro and biomass, but by June Wisconsin Electric Power will add power from two existing 660 kW Vestsas wind turbines to its mix.
