Wind Turbine Technology – Expensive, noisy, ugly and inefficient

Wind Turbines are the most inefficient of all renewable energy yet everyone in this country is forced to subsidise it in our fuel bills – even pensioners . . .

What we are told about wind turbine technology

Safeguarding the finite resources of the planet and taking effective action against climate change is everyone’s responsibility. Reducing our carbon emissions is the first step.

In the United Kingdom the use of wind power to generate electricity has become a media symbol for “going green”, with public perception being, “we’ve got to have them, haven’t we, if we are to do our bit”?

More and more wind farms are being built and planned. This must mean wind power can be the solution, that it can provide the supply necessary to meet our demand for electricity in the UK. Going green and keeping the lights on. Hurrah!!!! However????

Wind “The Uncomfortable Truth”

  • If the wind doesn’t blow a turbine cannot produce electricity. A wind farm in S.W. England typically operates ONLY on 2.5 – 3 days out of 10 because of the intermittency of windsupport
  • In high winds, wind turbines have to be shut down
  • The National Grid is responsible for ensuring we ALWAYS have electricity. Providing the supply to meet the demand. At peak times, such as viewing popular TV programmes, cooking Sunday lunch and in cold weather, the demand is high. At 3am in the morning, or in the summer, demand is low.
  • The ‘Supply and demand’ equation has to be balanced to a variation factor of less than 0.5% or electrical equipment will not work properly. Too great a supply, the light bulbs burst. Too great a demand, nothing works, the lights go out.
  • To ENSURE the ‘supply and demand’ equation is balanced, electricity is generated from a mix of coal, gas, oil, and nuclear sources to meet the predicted demand. Demand is calculated on a second by second basis for every 30 minute period of every day of the whole year. This is a complex and precise business, taking into account many variables.
  • Because wind is intermittent and cannot be ordered, controlled, or stored; its spasmodic contribution adds a whole range of extra variables for the National Grid to manage.
  • Because wind generation comes and goes, like the weather wind is very unpredictable, it can NEVER eliminate the need for other sources of electricity production.
  • The National Grid will always need a mix of “firm generation” (coal, gas, oil, and nuclear) to meet maximum demand on windless days regardless of how many wind turbines we have.
  • The actual contribution of wind power to the national grid is variable and can be minute. On average, in February 2009 when cold and calm, 0.6%, in June 2009, warm and calm, 0.2%. However many turbines you had built, these figures would not change. You would just have more idle turbines.
  • Power generating plants of other sorts will ALWAYS BE NECESSARY and also they have to be kept running to provide back up for when wind generation varies or disappears. Claimed savings of carbon emissions by wind power are greatly overstated because no mention is made of the “firm generation” providing the back up. Some gas power stations are dedicated to providing back up to wind.
  • On a windless day the same DEMAND for power remains. Where will the SUPPLY come from? Whatever mix of coal, gas, oil and nuclear “firm generation” we have and a similar mix to provide back up when it is wind.

WIND CANNOT REPLACE CONVENTIONAL POWER STATIONS…
