Evoluzione della domanda elettrica nel 2013

Energia elettrica
di Dario Rossi

Nel corso del 2013 si assiste ad un’ennesima contrazione della domanda di energia elettrica, che segue il calo già registrato nel corso dell’anno precedente. La curva di durata costruita sui soli prelievi fatturati dalle unità di consumo rappresentata in Figura 1 mostra uno spostamento verso il basso. Ad esempio, nel corso del 2012 un prelievo orario di almeno 38 GW è stato registrato in circa 3.000 ore, mentre tale valore viene raggiunto, nel 2013, in meno di 2.900 ore.

Il calo complessivo della domanda nel 2013 è risultato più marcato rispetto all’anno precedente (-3,97% rispetto al -3,3% del 2012), con un prelievo fatturato inferiore ai 290 TWh (302 TWh nel 2012). Dai dati si evince il forte calo dei prelievi nella macrozona sarda, passati da circa 10,5 TWh del 2012 a poco più di 8,5 TWh nel corso del 2013 (-17,68%) per effetto del calo dei consumi industriali, in particolare nel comparto dei metalli non ferrosi. Le flessioni risultano più contenute, sebbene significative, nelle altre macrozone (Sicilia: -4,05%; Continente: -3,44%).

Con riferimento alla Sardegna, i prelievi delle UC si mantengono sensibilmente al di sotto dei valori del 2012, con forti contrazioni nei mesi centrali dell’anno (-23%, in media, nel periodo giugno-agosto 2013 rispetto all’anno precedente).

energia para veículos

Não somente a energia elétrica deveria ser preocupação como também. É preciso pensar em novos combustíveis industriais e para lançamento de carros e a sua participação na poluição e depreciação do nosso planeta. Um dia o petróleo irá acabar. Deveriamos nos concientizar e focar no uso de álcool e outros recursos naturais

FH, as the federation

FH, as the federation overseeing the replica watches uk industry, is understandably bullish about these mostly pessimistic findings that you can view here in the "Swiss Watchmaking in August 2016" report. I won't talk about all the statistics, so I encourage those interested in the numbers of the watch industry to check it out. What I want to focus on is value, and the statement of "the fall in value was explained almost entirely by watches made of precious metals," as found in the report. The overall industry (Swiss watches sent out of Switzerland) was down 8.8% in August 2016, compared with August 2015. A recent report released by the Federation of the Swiss Watch Industry (FH) reveals that exports for precious metal-cased breitling replica watches plummeted during August 2016. It is true that the entire industry is seeing export declines but, interestingly enough, there are some areas of growth or less dramatic declines. The take away message for the people making product decisions in Switzerland is that consumers are fed up with bloated pricing, low value propositions, and products that depreciate faster than an aftermarket-customized G-Wagon. In other words, steel, titanium, and other high-quality, lower-priced timepieces are the rule right now. Precious metal watches which are gold and, to an extent, platinum and some other metals, were overall down over 25%, in a market that isn't exactly growing to begin with. Moreover, the FH reports that the major declines were in watches costing over 3,000 Swiss francs. Actually, omega replica watches priced from 200 - 3,000 Swiss francs have seen some growth, depending on price point, with a high of 11.7% increase in sales of watches with prices at around 500 Swiss francs. The numbers are pretty clear on a few things. First, smartwatches are not right now destroying the entry-level luxury watch market (as I predicted), and that consumers still want cheap replica watches but don't want to spend a lot on them.
