New Report by Dr Fred Udo - Wind Turbine Build-outs and CO2 emissions in Ireland

Dr Fred Udo, a distinguished engineer from CERN in Geneva, now retired, has published a new analysis on the Irish electricity system. In his previous report (link here), he used CO2 emission data from Eirgrid to show the inefficiencies created in the system by adding more wind.     In this latest report, he uses fuel input data from SEAI to show that the Eirgrid data actually underestimates CO2 emissions by about 6% and therefore the losses referred to in his previous report were too low.

The conclusions are really a damning indictment of the energy policy that resulted in such huge investment in wind and interconnector infrastructure. There is also an added sting in the tail - the investment of billions of Euros in new CCGT plant that could consume fuel more efficiently than before has been pretty much a waste because they have been forced to run inefficiently.

The performance of the system in 2011 shows clearly, that without the extra windmills and without the EDW link, but with the new CCGT gas units operating one does better than with all the new wind turbines and EDW link.

    What the actual hell?

    1. Some technical difficulties, should be working now

  2. According to the International Energy Agency, the use of coal for electricity generation is growing. This raises an interesting question. Take two identical Island countries like Ireland. A and B. Demand is a steady 4 GW. "A" generates all its electricity from coal, no renewables, no gas etc. "B" generates all its fossil fuel component for generation from coal plus 5gw of wind. So; A has 5 gw of coal plant only. B has 5 gw of coal plant + 5 gw of wind totalling of 10gw. The wind never blows at all in a given year. If the amount of coal burned in A is exactly equal to that burned in B, what contribution does coal make? Could it go like this. "A" 4/5x1x100% = 80 then for "B" 4/5x (5/10) x 100 = 40, So the ratio of power to fuel is 80 ; 40 giving the impression that wind is contributing half. . This flawed way of counting, treats wind as a fully operation component when it is not.
    Now increase wind in the above example to 100 gw. 4/5x(5/100)x100 = 4. So the ratio is 80 to 4 giving the impression that wind contributed 96% when it contributed nothing. The traditional way to measure generating capacity was "credit capacity" now they dispense with that and measure according to capacity without the credit.

  3. Note the comments of the ESB (Irish Electricity supplier before their monopoly was broken up) in their report in 2004. Go to page 23 and 24, in particular page 24, paragraph 2.,%20see%20above%29.pdf or google ESB report on wind generation on an all island grid system. In essence, it says that high levels of wind provide no power.
