Local planning boards are crafting regulations for wind turbines, and the company plans to fit other locations with the small-scale devices, pending approval.
Nor is Meijer the only company adopting roof-top wind. Cascade Engineering, which makes the units, expects to install 60 units in the coming months.
Including installation, the 8-foot rotary turbines cost between $10,000 and $12,000. The new stimulus package offers a 30% investment credit for renewable energy, which could offset that cost.
With good wind a turbine can generate up to 2,000 kWh of electricity — about 20 percent of an average house’s annual usage – using wind speeds between 8 and 40 m.p.h. This could translate into a savings of $200 a year, according to a company spokesman.
