Dont understand the £5.1Bn quoted as coming off Energy Bills. The price of Electricity is geared to Power Generation from ALL sources, infact Energy from Wind Turbines more expensive from wind farms than fossil fuel sources for some ridiculous reason. This is why Wind Turbines can be seen Idle for a lot of the time when the wind window is suitable because it is cheaper for the National Grid to buy power from Fossil Fuel sources rather than wind. National Grid buy their fuel from the lowest cost source, if WInd was cheaper then National grid would ensure Wind Turbines are ALWAY rotating and as such provide the Base Load. At least that is my simple understanding.
It would be ridiculous to purchase fossil fuel generation if wind was cheaper as such WInd Turbines would Always be rotating as long as there was enough wind to drive them and this is not my observation. I see 100's of wind turbines stationary even on days when the wind is in the wind speed window for their use.
If anyone reads the ORIGINAL posting of this thread, that was the basis of the thread and I have not seen a plausible explanation of why the numerous wind turbine are stationary on suitable wind days in all of the 36 pages of responses to this thread. Maybe I have missed a plausible explanation but it still remains that wind Power energy is more expensive than fossil fuels due to the pricing Policy of presumably government otherwise Wind would provide the base load for electric Power.
