The Performance of Wind Farms in the United Kingdom and Denmark
“The normalised load factor for UK onshore wind farms declines from a peak of about 24% at age 1 to 15% at age 10 and 11% at age 15. The decline in the normalised load factor for Danish onshore wind farms is slower but still significant with a fall from a peak of 22% to 18% at age 15. On the other hand for offshore wind farms in Denmark the normalised load factor falls from 39% at age 0 to 15% at age 10. The reasons for the observed declines in normalised load factors cannot be fully assessed using the data available but outages due to mechanical breakdowns appear to be a contributory factor.“

Already the grouting in the foundations of hundreds of turbines off Kent, Denmark and the Dogger Bank has failed, necessitating costly repairs.”

The Duke of Edinburgh has made a fierce attack on wind farms, describing them as “absolutely useless”.
Wind energy in the Irish power system.
This article describes the influence of wind energy on the CO2 output of the fossil-fired generation of electricity in Ireland. Where most available publications on this subject are based on models, the present study makes use of real-time production data. It is shown, that in absence of hydro energy the CO2 production of the conventional generators increases with wind energy penetration. The data shows that the reduction of CO2 emissions is at most a few percent, if gas fired generation is used for balancing a 30% share of wind energy.
A significant part of this crippling increase, helping to drive more than half Britain’s households into “fuel poverty”, will be the costs involved in covering thousands of square miles of our countryside and seas with wind turbines. The sole beneficiaries will be the energy companies, which are allowed to charge us double or treble the normal cost of our electricity, through the subsidies hidden in our energy bills; and landowners such as Sir Reginald Sheffield, the Prime Minister’s father-in-law, who on his own admission stands to earn nearly £1,000 a day at the expense of the rest of us, for allowing a wind farm to be built on his Lincolnshire estate.”
Why the £250bn wind power industry could be the greatest scam of our age – and here are the three ‘lies’ that prove it
Wind farms inefficient because they’re in “wrong places”
Does money grow in wind farms?
“The wind turbines required in Britain alone, says Prof MacKay, would amount to about double the number of all turbines in the world. Even then, “the maximum plausible production from on-shore windmills is 20 kilowatt hours per day per person”, about a sixth of Britain’s actual consumption.”
Whoa, windfarms in UK operate well below advertised efficiency
“It is clear from this analysis that wind cannot be relied upon to provide any significant level of generation at any defined time in the future.”
UK Government Looks to Scrap Funding of Inefficient Onshore Wind Turbines
The UK Government plans to scrap full subsidies to locate wind turbines in unsuitable locations and provide more democratic accountability for communities affected by wind farm proposals. To policy makers committed to making the current government the greenest ever, the challenge is that one-third of Britons think that the science on climate change has been exaggerated. Moreover, the hectoring approach has not worked, as castigations have led to more entrenched opposition and a lack of consent for local wind farm developments. The Energy Minister said “At present, too often a community can see what it will lose by having a wind farm in its midst [local impact from the turbines], but it cannot see what it gains [less expensive grid connections].”

Does money grow in wind farms?
Wind turbines are a poor way to harness energy – but a very good way to generate public subsidies, says Andrew Gilligan.

Wind Energy Supply Dips During Cold Snap
Wind power targets unrealistic, say critics
Claims in a Government-commissioned report that wind power can supply a third of Britain’s electricity have been condemned as wildly optimistic by leading experts.
