While being aware of how little energy wind turbines develop, I would have more time for their claims if they would cut the cant about global warming, saving the world through reduction of CO2 etc, and come out into the open and tell us how much profit these machines collect from the subsidy we all pay. Let developers tell us just how much profit they are making and, while developing this theme, perhaps the British Wind Energy Authority would also like to make a statement on this, that is if it can keep off the "we are saving the world" statements and "global warming being a greater threat than terrorism".

The likes of wind farms and other similar ventures have always been seen as more of a headline grabber in the UK rather than a real alternative for the future. The authorities have given minimal tax incentives for companies to get involved and there have even been complications with getting them connected to the national grid. All in all the alternative energy market has been launched and re-launched on many occasions but it is just not working.

In Swansea we have the threat of possibly a massive, useless wind farm being built on Mynydd y Gwair Mountain which will visually pollute this area of outstanding natural beauty from the Gower to Brecon Beacons, Powys and Cardigan Bay, in other words, about a quarter of Wales. Why? Because the Welsh Assembly Government wants to build wind farms to provide intermittent, stuttering electricity supplies which we do not need. How daft and subservient can we Welsh get!

This is the first breeding success at this site in 11 years. The parent eagles must have been pampered with plenty of live rabbits to make sure this would happen. All in all, two million pounds have been spent to produce a "success story" at Beinn an Tuirc. So much money is at stake here: the approval of hundreds of wind farms where eagles fly, in Scotland and in the world, hinge upon this kind of favourable publicity.

Gradually, the message is beginning to sink in. With wind farms already growing in unpopularity, people are now waking up to the gigantic scale of the rip-off being perpetrated. As more and more people begin to understand this, it should only be a matter of time before the whole programme crashes and burns. But, there is one minor problem ... wind energy is an EU-supported obsession. To stop the scam, we have to confront the EU. Is there a politician brave enough to do this?

The total power generated by all the 2,300 turbines so far built in Britain, is less than that contributed by a single medium-size conventional power station. ...Far from being "free", wind is one of the most expensive ways of generating electricity yet devised. Without an almost 100 per cent subsidy, unwittingly paid by all of us through our electricity bills, no one would dream of building giant wind turbines in Britain, because their cost is not remotely competitive.

In the next decade, we are due to lose 40 per cent of the generating capacity that keeps our lights on and our economy running. Within a few years, eight of the nine nuclear plants that supply 20 per cent of our power will come to the end of their life. ... To address our looming energy crisis with the urgency it calls for, we would not only have to ignore the fantasies of Mr Hansen and the green lobby, but also directly confront our government in Brussels, which stands in the way of almost every measure we need to take. In this sense, in terms of what it will cost us, energy looks to become the defining issue of our EU membership.

The land affected by this monumentally inappropriate industrial development is set to dominate and face the central heart of Sutherland. ...This is not just a Brora-Helmsdale issue but one that must be for the individual and is now of national and international importance. Our complex peatlands and wildlands are among some of the finest tracts of singular landscape beauty and rare habitat within Europe. All this is meaningless to the developers and their contractors, whose careless handiwork is already in monumental flailing form, demeaning and dominating sites around the Highlands.

It's probably too much to expect, but, following the country's latest landslide or bog overflow, county councils and An Bord Pleanála should have more regard for people living in susceptible areas. Despite the concerns of people in Derrybrien, Co Galway, regarding a wind farm in their area, planning permission was granted for it by An Bord Pleanála. Residents' worst fears came to pass when a landslide caused devastation in 2003. Fast forward to August, 2008, and a similar landslide involving 20 acres of bog in the Kielduff/Lyrecrompane area of Co Kerry. ...The Irish Peatland Conservation Council (IPCC), which aims to save Irish boglands, is calling on the Government to come up with a policy on the location of wind farms in sensitive habitats.

For many years security of supply has taken a back seat in energy policy. We have been more concerned with price and, latterly, reducing emissions. ...security of energy supply must also be put back on the agenda with an equal priority. That means developing a mix of renewable generating forms including wave, hydro and biomass, which have more predictable output than wind turbines.

A landmark court ruling has ordered that Jane Davis be given a discount on her council tax because her £170,000 home has been rendered worthless by a wind turbine 1,000 yards away. This is effectively an official admission that wind farms, which are accused of 'spoiling countryside views and producing a deafening roar', have a negative effect on house prices. ...One of these impacts is of course safety. In June this year a 16-foot wind turbine blade smashed through a farmhouse roof in Northern Ireland as the farmer and his family slept inside.

I am extremely concerned at the detrimental impact the construction of wind turbines on the land adjacent to High Elms Lane, Benington could have on wildlife. It is well known locally that this site supports a large and varied wildlife and many of the species are of national and international importance. It has taken a long time and sympathetic farming to encourage so many species to thrive in this area. A total of 26 mammal species (not counting bats) and 75 bird species have been recorded around the proposed wind farm, along with various amphibians and reptiles.

A series of events on bats look set to be overshadowed by problems affecting the mammals' chances of survival, according to an expert. Anne Youngman, the Bat Conservation Trust's Scottish officer, said wet weather may have hit the breeding season for a second year running. ...On the agenda is a presentation on wind farms in mountain areas of Portugal. Ms Youngman said: "Wind farms were a hot topic at the last symposium. "In Germany, there are turbines above forests and the mortality rate of bats has been found to be high.

Energy secretary John Hutton yesterday gave the go-ahead to plans to build eighteen 125-metre high turbines, at Middlemoor, near Alnwick. But it cannot be built until energy giant npower comes up with a way of preventing the turbines interfering with RAF radar systems. Nick Blezard - chairman of the Save Northumberland's Environment, which opposed the project - says this is effectively a refusal given the radar issue. We can only hope he is right and that the Government - reluctant to admit defeat - is spinning Middlemoor as a "go-ahead" knowing that the radar caveat will halt the project.

It is bad enough to be told by the First Minister that Scotland's landscapes are to be sacrificed to achieve irrelevant SNP targets for renewables but he now claims that another reason is to help Europe achieve theirs. I refer to the disgraceful announcement that the gateway to Scotland, the A74 at Abington, is to be covered by 152 x 406 foot (that's 90 feet taller than Big Ben) turbines spread over 11,707 acres (18.3 sq miles) of our countryside.

Casting about for the least unpopular "solution" to the problem, politicians find a seductive answer: wind power. The wind power debate is full of cant which the bemused public cannot evaluate. Misrepresentation is inevitable where vested interests have so much to lose. Take away the enormous subsidies, and all the wind generation applications would disappear in a flash. If our politicians claim vision and courage, they should concentrate on strategies to generate real economic and environmental benefits and deliver long-term social advantages.

But what of wind's performance as an energy provider? Wind generation does not provide a reliable supply of power. It must be ‘shadowed' by baseload power stations such as nuclear and coal as it is intermittent. Over-reliance on it could lead to supply interruptions if the wind does not blow, blows too hard or does not blow where the wind farms are located. Importantly, such high-demand periods of cold and hot weather correspond to periods of low wind so overdependence on intermittent wind can actually increase carbon emissions as conventional power stations are required as back-up. Importantly wind farms perform well if their average output reaches as much as 35% of their generating capacity, but this rarely happens. Evidence shows that, throughout Europe, wind turbines have produced on average less than 20% of their capacity in recent years.

Your reporting of the Government's energy policy focuses on the supply problems that make the building of 7,000 wind turbines onshore and offshore by 2020 infeasible (News & Christopher Booker, June 29). But there is worse hidden in the 267-page consultation document. ...It is not until page 228 that the document says: "We will also need to consider the potential environmental impacts such as those on biodiversity, landscapes, air quality, soils and land as well as the marine environment." So much for our landscapes and historical assets.

Power stations cannot be minutely adjusted to suit wind variations and this results in back-up so that there is no fossil generation displacement and consequently no emissions saving. Wind farm operators who claim X thousand tonnes of CO2 savings are being conjectural, and there is no evidence of any saving.
