Kalahari Resort installs Wisconsin’s largest solar hot water system

The Kalahari Resort in Wisconsin Dells is the home of a new 104-panel solar hot water system – the largest in the state.

Supplying more than 10 percent of the resort’s hot water needs, the system will offset 69 tons of greenhouse gas carbon dioxide from entering the earth’s atmosphere each year. The new system was completed with the help of a $50,000 Implementation Grant from Focus on Energy’s Renewable Energy Program.

Other steps the resort has taken to reduce energy costs include:

  • Installed Entergize Energy Control Systems in all guest rooms, which control energy use based on guest occupancy.


  • Installed 844 low-flow showerheads in guest rooms, reducing water consumption by 2.46 million gallons per year.


  • Replaced 60-watt incandescent light bulbs with 15-watt compact fluorescent light bulbs in 5,500 fixtures, saving 294,000 kWh per year.
Kalahari management estimates the resort will save $400,000 in energy costs annually as a direct result of these initiatives.
