Found a few of these the other day. Might be a bit big though.  |

You can pick up second hand ones of those very cheap ...... although transport can be a problem.
I suspect that soon you could be well paid to actually take them away
Something the green energy enthusiasts have not yet realised is that being resin reinforced fibre construction they require quite a lot of oil/energy and carbon dioxide production in manufacture and are virtually indestructible waste (after only quite a short lifespan)

If they save more fossil fuel burning than is used in the making, then it's worthwhile. Indestructible? Could be crushed up and used for hardcore. My guess would be that they save far more oil than is used in the making of them. Perhaps naughtyfox would like to do some worthwhile research for us, a bit of useful cut and pasting. |

Wind turbines are into profit very quickly they are also carbon free very quickly, they can be turned off when not need unlike coal fired power stations, they are also having their lives extended as time goes on and its realised how strong they are. Concrete creates huge amounts of pollution and any fossil fueled power station continually creats pollution whilst in use and then creates even more pollution in its when its destroyed. Overall Jim like you I believe we need to stop using fossil fuel for making electric and wind turbines do that.

Quite possibly Jim However at the moment it is not something that has really been thought through, Your comment about hardcore is valid as experimentally it is being used as ballast for concrete ..... although to be honest it's not really a total answer as it still leaves the problem of the concrete when that reaches the end of it's life. How many times is it possible to recycle?
Something else they have been talking about is using sections of them to make bridges ..... that sounds a bit fanciful to me and it still leaves the problem of what you do with it when the bridges are clapped out. ...... the quantities are formidable and it's something that people have barely started to look at

They are looking at full recycling for them John as per my link above |

They are looking at full recycling for them John as per my link above That is my point Peter ...... they are looking (and let's be honest also hoping that they find something as a replacement that is not appallingly polluting)
but at the moment it is still (with the possible exception of the concrete) a problem caused by the race to wind power that has not been thought through.
It's something that often happens with big leaps in new technology ..... there are major downsides that often cause massive problems down the line because nobody thought everything through .... it's often Hooray !! we have a solution ..... and everybody jumps in.

But, Shirley, the decommissioning problems are miniscule compared to a nuke plant. |

Trouble is John their is lots of concrete in fossil fuel energy plants. Their is no clean energy their is just cleaner energy, I think we have to live with that for the moment. I was reading that Rolls Royce are getting the go ahead for their small nuclear plants cutting out the Chinese |

I started a degree in renewable energy systems at Loughborough university in 2003. Moored nearby at Bishop Meadow lock moorings.
A subject I really like but I was a bit older than all the students and my maths was a bit rusty having not been in education for several years so I only lasted one term before the lure of boating was too much and I escaped via Leicester over the christmas stoppage break.
That was a nice boat trip actually, in the snow and ice.
The mooring there above the lock is not amazing. Astra Zeneca animal torturing site opposite and a massive shit farm beside the moorings. Less than ideal.
One thing I do like about wind turbines on land is that the land can be used for farming while the turbine itself takes up very little room. Seems rather an efficient way to use land.
Obviously offshore is much more popular but I believe this is to do with the problem of a lot of land being privately owned.

Interesting article.
I never really understood the argument against landfill.
You dig stuff out of the ground make things out of it then chuck it back under the ground when you have finished with it. The net gain/loss is zero.
I suppose in the case of glass the sand is dredged so it would be awkward to get it back where it came from.
It seems logical to use landfill for inert waste.
There's gold in them there hills !

The problem is that waste is not put back into the hole it came out of, and it is all mixed together allowing chemical reactions to create nasties. A local 'recycling' company had to buy a house in a village about 1/2 mile away from an old quarry used as a landfill. Gases produced leached into old mine workings and under the village, or the landfill took away the natural ventilation from the old mines. They bought the house where it was first noticed and installed much monitoring equipment. The argument still rumbles on after 25 years.
