When it finally opens next year, the Green Leaf Inn in  Wisconsin will be the only hotel in the United States that generates as much energy as it uses.

The Inn will use a wind turbine, solar power and geothermal energy to produce electricity, warm and cool air and hot water.

Other sustainable features include a 30,000 gallon underground tank to store rainwater for filling toilets and watering the landscape; a charging station for battery-powered cars; its own waste treatment system and suites with energy systems that shut down automatically when guests leave.

And it leaves no carbon footprint.

Located outside Delavan and near Lake Geneva, the 19-room Inn offers  hot tubs in every suite, wooden furniture and extensive gardens. Couples and groups can come to Green Leaf to relax and if they choose, learn about green living.
