A story from WEAU News:

A western Wisconsin hospital wants to harness some of the mighty Mississippi’s power for its own energy needs.

Gundersen Lutheran Hospital is hoping to get approved to build seven hydrokinetic turbines at a Mississippi River dam, which the hospital says would provide about 90% of its energy needs. The hospital says it would take millions of dollars to create, and would use a local power company to convert the power. It’s in the permit stages now, which the hospital says could take three years.

“Versus wind which you never know whether the wind is going to be blowing or the sun is going to be shining so we think that this is a really good alternative as a renewable energy source,” says Jeff Rich with Gundersen Lutheran.

Rich says the hospital could recoup the cost of the project in about ten years.
