The Things They Never Told Us About Wind Power

An article at the Center of the American Experiment website tells us some of the things the media might not have mentioned about wind power:

An industrial wind facility in Kewaunee County, Wisconsin has been decommissioned after just 20 years of service because the turbines are no longer cost effective to maintain and operate. The decommissioning of the 14 turbines took many people by surprise, even local government officials and the farmer who had five of the turbines on his property.

What’s really surprising about these wind turbines being decommissioned after 20 years is the is the fact that people were surprised by it. You’d be astonished at how many people I talk to that have no idea that wind turbines only last for 20 years, maybe 25. In fact, the National Renewable Energy Laboratory says the useful life of a wind turbine is only 20 years.

The following chart appears in the article:

So what do we do with these things after they have lived their useful life span? Can we dispose of them in a way that is environmentally safe?

The article notes:

The short usable lifespan of a wind turbine is one of the most important, but least-talked about subjects in energy policy.

In contrast to wind, coal, natural gas, and nuclear plants can run for a very long time. Coal and natural gas plants can easily run for 50 years, and nuclear plants can be updated and retrofitted to run for 60 years. This has profound implications for the cost of electricity on a per megawatt hour basis that seemingly no one is talking about.

When the federal government puts out their cost projections for energy, the numbers they produce are called the Levelized Cost of Energy, or LCOE. These numbers are supposed to act as a measuring stick that allows policymakers to determine which energy sources will best serve their needs, but these numbers are wrong because they assume all power plants, whether they are wind, coal, natural gas, or nuclear will have a 30-year payback period.

This does two things, it artificially reduces the cost of wind power by allowing them to spread their costs over 30 years, when 20 would be much more appropriate, and it artificially inflates the cost of coal, natural gas, and nuclear by not calculating the cost over the entirety of their reasonable lifetimes.

The search for totally green energy is not unlike science’s search for a perpetual motion machine. Scientists and engineers may come close, but the perpetual motion machine cannot exist because it contradicts the laws of physics.
