Italian cinema between economic crisis and a desire for change

"Alternative energy will never be able to fully meet the energy needs of Italy." Often you hear phrases like this. Instead Sunday afternoon for two hours, solar, wind and hydroelectric power have produced 100% of the electricity consumed in Italy , bringing the purchase price of electricity, the Pun, to zero in on the whole national territory. A report the news, along with a graph of energy consumption of GME and the portal QualEnergia . "A phenomenon, that of the wholesale price of electricity to zero - writes QualEnergia - which so far occurred only for some zonal prices, but  never for all areas of the country , bringing the Single National Price , ie the Pun , to zero. A similar event had been touched on Sunday, June 2, 2013, when the average minimum time it amounted to 0.46 € / MWh, but with a lower demand than on 16 June.

A recent study showed Althesys as the only PV in 2012 had moved to the values ??of the hourly averages of prices, so that today  the price spike no longer coincides with the peak demand  for electricity. The analysis considered both the lower prices in the solar hours, estimated at 1,420 million euro (of 2011 were 396 million) and higher prices in the non-solar hours, amounting to 586 million:  net peak shaving  in 2012 resulted thus 838 million of euro . For  Gianni Silvestrini , scientific director of QualEnergia, "what happened Sunday, June 16 is a further demonstration of the effects of rapid penetration of renewable energy in Italy, which in May even have covered  more than 50% of the production of electricity . " "In addition to affecting the net savings in terms of electricity prices and the reduction of emissions - said Silvestrini - the diffusion of renewable energy also leads to a  decrease in imports  of fossil fuels, reducing the high negative balance in the national energy balance " .
