Titolo: Una critica anglosassone al fotovoltaico della Germania

February 4, 2014, Robert Wilson quoting Feynmann:
 
""For a successful technology, reality must take precedence over public
relations, for Nature cannot be fooled."
 
and in it's own words:
 
"Ramping up renewables quickly, building more coal power plants, closing
nuclear power plants, and doing very little to reduce carbon emissions."
 
"Germany's solar build up, instead of being a huge success, was a massive
mis-application of much needed effort."
 
"In 2012 Germany had one third of the world's solar panels, and at one point
these panels generated over half of Germany's electricity demand. This is how
things are normally put. But it as rather like talking about a third rate
golfer and only referring to the time he almost won the US Masters.
Yes, Germany got 50% of its electricity from solar one afternoon.
Throughout the year it only produced 5%. The 5% is what really matters.
The 50% gets all the headlines."
 
"And solar is an awful source of energy in a country as cloudy and as far
north as Germany. Electricity has to be available when we want it."
 
"Germans, like many Europeans, most want the stuff around 6 pm on a cold
Winter evening. This is an incredibly reliable peak in demand."
 
"Yet, the electricity supplied by Germany's solar panels at 6 pm on a
cold December is also incredibly reliable: zero."
 
"Physical realities mean that Germany's solar panels generate a pitiful
amount of electricity for a large part of the year. This is demonstrated
by comparing the output of Germany's solar panels in July 2013, 5.1 TWh,
with that in January 2013, 0.35 TWh. This is a difference of more than an
order of magnitude. Solar is unlikely to be anything other than a marginal
source of energy in Germany ..."
 
 
Mo vediamo come commentano un "blogger" diverso da quelli che continuano
a propinarci.

 massive mis-application of much needed effort."
 
Non ho pensato a leggere i commenti, ecco questa chicca:
 
"If a German chooses PV over nuclear that's a personal choice.
If a democracy chooses to subsidize PV and/or nuclear it's that
country's choice."
 
La questione posta in questi termini, puo' andare. Ma e' una menzogna.
Non e' in alcun modo vero che il PV stia sostituendo il nucleare.
E' vero invece che il carbone sta sostituendo il nucleare.
 
E non e' affatto vero che la scelta del carbone sia una scelta personale
dei tedeschi.
 
E' cosi' falso, che se l'inasprimento del clima, la maggiore
violenza degli eventi naturali causati dalla sempre crescente presenza
di CO2 nell'atmosfera, venisse considerato dagli Stati Uniti l'equivalente
di una guerra meteorologica con mezzi impropri, non sarebbe poi tanto
fantascientifico postulare l'ipotesi di un bombardamento nucleare
sulla Germania per "farli smettere di emettere enormi quantita' di CO2
dalle sempre piu' numerose centrali a carbone" (alla faccia degli impegni
presi a Kyoto), visto che non paiono volere intendere ragioni.
 
Dopotutto non ci sono molti modi ragionevoli per contrastare il fanatismo
ideologico, salvo imbarcarsi in una sanguinosa guerra USA-Europa (visto
che la Germania controlla mezza Unione Europea ... ed i francesi non
sarebbero tanto d'accordo, trovandosi a due passi).
