Costly Broken Wind Turbines Give College Whopping Negative 99.14% Return On Investment

Lake Land College recently announced plans to tear down broken wind turbines on campus, after the school got $987,697.20 in taxpayer support for wind power.

The turbines were funded by a $2.5 million grant from the U.S. Department of Labor, but the turbines lasted for less than four years and were incredibly costly to maintain.

“Since the installation in 2012, the college has spent $240,000 in parts and labor to maintain the turbines,” Kelly Allee, Director of Public Relations at Lake Land College, told The Daily Caller News Foundation.

The college estimates it would take another $100,000 in repairs to make the turbines function again after one of them was struck by lightning and likely suffered electrical damage last summer. School officials’ original estimates found the turbine would save it $44,000 in electricity annually, far more than the $8,500 they actually generated. Under the original optimistic scenario, the turbines would have to last for 22.5 years just to recoup the costs, not accounting for inflation. If viewed as an investment, the turbines had a return of negative 99.14 percent.

“While they have been an excellent teaching tool for students, they have only generated $8,500 in power in their lifetime,” she said. “One of the reasons for the lower than expected energy power is that the turbines often need to be repaired. They are not a good teaching tool if they are not working.”

Even though the college wants to tear down one of the turbines, they are federal assets and “there is a process that has to be followed” according to Allee.

The turbines became operational in 2012 after a 5-year long building campaign intended to reduce the college’s carbon dioxide (CO2) emissions to fight global warming. Even though the turbines cost almost $1 million, but the college repeatedly claimed they’d save money in the long run.
