Wind Energy Debate : Who is right - Alex White or Fred Udo ?

Alex White, lawyer and Trotskyite                                             Fred Udo, distinguished Dutch engineer

Ireland's Energy Minister, Alex White, was interviewed by RTE radio yesterday. It can be listened to here :

RTE Radio 1, This Week: Ireland and Wind Power

It was a groundbreaking interview in a way, as it was the first time the technical nuts and bolts of wind energy policy was discussed in the mainstream Irish media :

Richard Crowley, interviewer : What is the ratio of wind energy to CO2 emissions savings ?

Alex White, Energy Minister : We reduced CO2 emissions by 2.6 Megatonnes.

Lo and behold, our energy minister does not know this crucial ratio ! The answer (for 2012) is that for each kWh of wind generated, associated emissions and fossil fuel savings are 0.33 kWh* due to increased ramping and cycling of gas plants (well below 1MW wind to 1MW savings as often claimed). This ratio will get worse with very high penetrations of wind. Recent analysis by Irish Energy Blog shows that wind reduced gas imports by just 2% year on year in 2014.

His lack of technical knowledge was shown once again when the minister referred to two Canadian reports into health effects of wind turbines but could not say what the setback distances were that were used in these reports. If anybody knows which reports he was referring to please do let me know.

These are just a sample of our Energy Minister's lack of in depth knowledge of his brief displayed during the interview (e.g. comparing cost of biomass with wind). Have a listen yourself.

Fred Udo's excellent reports can be read here :

Oh and by the way it's Udo - not U.D.O !



*Correction to original ratio of 54% by Fred Udo

54% is the part calculated within the framework of SEAI.
Additional losses: 
Self energy plus extra HV lines: 10%
The SEAI calculation takes only the static behavior of the generators.
Indication: The CO2 emission calculated by SEAI/Eirgrid is 7% too low.
If one attributes one third of this to wind and the other ⅔ to the daily ramping, one loses another 10%
The total efficiency of wind is then 33%.

Energy Minister shows he is out of his depth


He said Denmark, which generates 140 per cent of its energy needs through wind energy, had 5,000 turbines, compared with the Republic’s 1,450, despite having half the land mass - Minister For Energy, Alex White, September 2015.
Denmark generated 140% during one night. The following morning they were barely getting any of their energy needs from wind, with Denmark reliant on imports from Norway and Sweden :

The implication given by the Energy Minister was that Denmark is generating 140% of its needs from wind all the time. This is an ignorant view and shows he is way too far out of his depth to be deciding energy policy at this time.

Denmark is also unique in that it can easily import and export to Norway, who have large amounts of the most suitable back-up for wind, namely hydro.

The UK do not want our wind. They have said as much. 

And France will not want our wind either. Nuclear plants cannot be ramped up and down like hydro. So Ireland will have to dump all its excess wind. Ireland does not have access to a Nordic type back up system so why is the Minister making comparisons with Denmark at all ?


Maros Sefcovic, vice president of the European Commission in charge of energy union, also spoke about how the integration of Europe’s energy markets, billed as the biggest transformation since the pooling of coal and steel production in the 1950s, had been accelerated by the West’s increasingly fractious relationship with Russia, which supplies most of continent’s natural gas.
While Germany and Italy are dependent on Russian gas, Ireland get's its gas mostly from Norway and the Netherlands.
