On our holiday travels, I went through western Iowa on I80.

For those that haven't been there, there are a large number of windmills MidAmerican put in a while ago.

On this trip, my wife was driving and I noticed something. Many if not all of the generators have bene replaced. They are all less than 10 years old.

There are boilers out there making steam for power that were built in the 60s.

When you talk "Green" what you mean is "Disposable."
