Wind Turbines.

29 million homes in the UK times 25 grand and for just seven hundred and 25 billion we can all have a new solar roof .

New HS2 pilot project swaps steel for retired wind turbine blades to reinforce concrete

Innovation believed to be world-first Process cuts carbon production by up to 90%

Adds another layer to the gravy train and ultimately just buries the problem for future generations to deal with , at least steel will eventually degrade returning natural elements to the earth from which it came .

"Worn-out wind turbine blades destined for the incinerator"

Now there's a novel idea. Burning fossil fuels to generate electricity...

Reading the write up not that good to be used for temporary roads siting porta cabins sounds very temporary and what is to be done with what they cannot use not a lot of thought gone into this

I don't pretend to understand it all but if my chimney idea were little more than a pushbike dynamo feeding power to the mainline housed in a plastic box with a spinner on top what would it cost to mass produce , 2 quid per house maybe ?

fourteen hundred and 50 billion to produce 29 hundred billions worth of electricity annually seems a fair investment .

With 7 pages of discussion on wind turbines we have established that the carbon payback is about 3 years and the 2 main objections are that they are an eyesore & the blades are difficult to recycle.
Any modern infrastructure can be seen as unsightly especially in rural areas but the rationale given is that it's essential .This surely is the crux of the matter .
As with HS2 perhaps we should take with a pinch of salt the so called need for these mega projects - massive solar and onshore wind included.
Nuclear seems to be less attractive because of cost , let alone the problem of treating and safely storing the waste & the possibility of a catastrophic accident .
Wind and sun are now the cheapest wat to generate per MW and most of the materiales are recyclable .I wonder what percentage wind turbine blades make up of the total amount of composites scrapped each year ? Given that household waste alone amounts to 25 million tonnes per annum .
Of course the the looming catastrophe of irreversible climate change should be the main factor in this debate not what looks ugly . Scientist and engineers should be leading this debate with data the can be verified.If this is left solely in the hands of politicians and corporations the "solution" will be the outcome that produces the most profit short term , with us , the taxpayers picking up the bill as usual.

While the same 7 pages have me convinced burning the money would be just as good for the planet if not better .

yes burn all the money

This was an interesting analysis of the Australian energy market and how the role of constant output is a problem:

Why coal can't keep up with Australia's electricity jigsaw puzzle

When the early closure of Victoria's second-biggest coal-fired power station was announced last week, something the energy minister said was less than complete, writes Peter Martin.

this sounds interesting .small sacale , locally produced electricity can and should play a part in our needs.

A good article that Paddler.
Australia at least for now is the largest LNG producer in the world, It makes no sense to be burning coal which produces twice the Co2.
The real problem is that mining companies may as well have their hands up the arses of politicains and work them like a sock puppet.
It's different now but at one point the UK had a larger solar power production than Australia … Something is very wrong.
