Some turbines are dismantled as scrap metal while others are refurbished and sold to third world countries.
The site is clean, ready for other uses like agriculture or parks.
Decommissioning a wind farm is as easy as child's play compared to coal or nuclear power plants.
On the other hand, huge problems arise when decommissioning nuclear power plants.
The following is an example taken from the UK situation. Read on folks. This is truly a sad case.
http://en.wikipedia.org/wiki/Nuclear_decommissioning
A wide range of nuclear facilities has been decommissioned so far. This includes nuclear power plants (NPPs), research reactors, isotope production plants, particle accelerators, and uranium mines. The number of decommissioned power plants is small. There are companies specialized in nuclear decommissioning; the practice of decommissioning has turned into a profitable business. Decommissionning is very expensive. The current estimate by the United Kingdom's Nuclear Decommissioning Authority is that it will cost at least £70 billion to decommission the 19 existing United Kingdom nuclear sites; this takes no account of what will happen in the future. Also, due to the radioactivity in the reactor structure, decommissioning is a slow process which takes place in stages. The plans of the Nuclear Decommissioning Authority for decommissioning reactors have an average 50 year time frame. The long time frame makes reliable cost estimates extremely difficult. Excessive cost overruns are not uncommon even for projects done in a much shorter time frame.
Comments, anyone?
Well, we'll need something to produce power on still days...
That's it? Come on Grump! Nuclear is your ... "something"?
Nuclear is the ultimate destruction of the land it sits on. Too expensive to build, lethal fuel, fuel rod waste disposal nearly impossible, decommissioning nightmares and centuries of contaminated waste land hovering all over the UK countryside.
Would you think the UK government is subsidising the nuclear decommissioning?
No, they are not. They are paying the full 70 billion. Your wallet is hurt again!
If you are going to post old wind turbine pictures, think twice.
Decommissioning green energy power plants is definitely not an issue because the technology is clean to begin with.
All the others are just necessary evil.
