Clean up is sometimes a problem in the real world. A strip mining company, for example. has to clean up after it has removed the minerals it has mined. This involves filling in the hole, disposing of the slag (these two are usually connected) and re-contouring the land.
Green projects shouldn’t have their own set of rules. They need to cover all their costs, including clean up.
In addition to removing these cylinders, the batteries that many of them have need to be carefully disposed or possibly re-cycled.
Oh, the “school solution” when there are clean up costs is to have the company post a bond, equal to the present value of the expected clean up cost.
Don’t get off track here. I think the moral of this story is if wind power is so great why were these wind mills not replaced so they could produce more cheap energy?
