This is the final proof. Sadly the disputation over this issue illustrates the way scientists are not immune from prejudiced and nasty behaviour, a considerable amount of which my efforts to analyse renewables has evoked.
I fully disagree and I have shown in several occasions the reason why: This is what has been generally considered in most of the studies carried out to date and what is proposed by some authors as the recommended methodology.
The first thing is to confirm that no EROI studies can be taken seriously if the range of results varies so wildly. If anything, Prieto ought to be skewing results towards a high solar PV EROI since he built some of the solar plants Singapur como caso de exito essay writes about in the book.
Both his poetry from on and his essays in literary criticism attest to his spiritual independence. It is curious that virtually all manufacturers give a maximum of 25 years of power guarantee of their modules with the corresponding degradation process over the years and 5 years of material guarantee the later superseding or prevailing on the former in case of failure and we find scientists happily granting 30 years for the EROI studies.
It is true that they dared to write our publisher asking him to stop publishing the book when it was in a draft version in a sort of censorship I had not seen since several centuries in medieval Spain.
April 1, update: Our methodology is clear in these conversion units and reflects a quite direct relation between GDP and total primary energy spent in Spain or between active labor and energy spent per laborer or any given and specific related industrial activity or service rendered.
This is exactly what is happening with the energy sources and its properties and qualities: Stealing in Spain, for instance, is not relevant, but in many countries of the world it is a problem.
Esquema de un condensador Si se aplica una diferencia de potencial a ambas placas, estas se cargan, una con cargas positivas y otra con cargas negativas de forma proporcional al voltaje que se aplica.
I would just recommend the IEA tour Spain it is not the worst country in solar PV systems; on the contrary, it is one of the most efficient in terms of MWh produced per Mw installed.
The study, as many of you may already know, was on a real world installed plant in the best irradiated country in Europe Spainwith the official and very accurate energy production records of the Ministry of Industry read by telemetry to more than 40, digital sealed meters in each of the respective individual plants over a period of three complete years At the very least Prieto and Hall should be commended for getting the whole messy issue of boundaries and components, and appropriate energy cost assumptions for the various components, on the agenda.
Then came oil, much more dense and versatile than coal. In that case, an energy system. Datos de United Nations Development Program. Springer, in the bulky references, that occupy almost as much space as the article in itself. Springer appeared, there were already many variances and divergences.
On another occasion, where it took over a year to get through the difficulties, I was presented with a seven page essay disagreeing with elements in my case.
One of the factors, a7 the energy input required for modules, inverters, trackers if any and metallic infrastructures, labor excludedwas precisely the EROI as usually calculated by many authors. I have another case where possibly a c 50 word review from probably the most prestigious individual in the field said the paper was good, but the paper was rejected because a second even shorter review was unfavourable.
After my experiences of several years in the field with different technologies, typologies, topologies, latitudes and state of development countries and confronting with the real world results, Charles Hall and myself, after having had a pint of beer in an Irish Pub in Cork commenting these issues, in the ASPO International Conference held there indecided to embark in a study on solar PV.
With more than GW of installed plants worldwide, and several complete yearly cycles of operation of many of them, it is going to be increasingly difficult for some authors to continue with the academic approach, to verify real behavior of the EROI. For example, ethanol studies using narrow boundaries found higher EROI values than those with the widest boundaries, which often found a negative EROI.
By the end of the conference I was a bit frustrated at the lack of discussion of boundaries. Some more could be found in many places.Este es un caso que nos llegó por recomendación de otro cliente y supimos dar la solución que les pareció más adecuada a su necesidades, esto además de para vivir la experiencia sirvió para que ellos mismos se constituyeran como un equipo de Impulsores de.
