The friend Orsovolante published a great post, I agree fully and republish to add my two cents of vision ..
only add that it would be useful to assess the costs of the alternatives as a whole, and consider that they are not THE solution, but only to support an energy policy that would diversify and be more respectful of the environment and humans.
-----------------------------
Yesterday while returning from Tuscany to Piedmont, I noticed the large number of plants Solar panels are being built on the hills of Asti and of the Alexandrian.
time ago I noticed the same proliferation in Cuneo Langhe.
Now I believe that the solar investment is a worthy thing, but I feel that just as things are taking place in Italy, you are risking do damage, and large, even in this field.
And I think the fundamental reason why this happens, it is the political will to want to ensure large profits in a few subjects rather than to distribute the benefits among all. Let's be clear
well. I do not mean that the big investors do not have to act in this area or that you should come to a kind of community energy, but I think that the success of "alternative" is inseparable from the ability to "produce from below."
My idea, already expressed in very difficult times, is that the production of solar energy (but in some cases, wind power, geothermal etc. ..), goes well with the concept of micro and mini production ".
To be clear I think that it would require legislation that would allow all of the construction of the roof, or just to put a panel in the garden or on the terrace instead of a parabola.
In theory it may be in ... complicated bureaucratic practice is such that everyone I know , lose or give up entirely to completion, or entrusting it to companies that take charge of the implementation and bureaucracy, but also take part in exchange for the proceeds and did retain control on the plant for several years.
Well ... actually we are far from what I saw years ago in a German supermarket where it was sold a kit with 2 solar panels, the special counter for the energy exchange with the line, and the only 2 modules were attached to be completed to fulfill the bureaucratic requirements.
This has also another consequence. It 'clear that a large company has little interest in wasting time with two panels that can be mounted on the roof of the shed in the garden. Much better, from his point of view, to invest in a large facility, maybe covering up the hill to the left of the panels. Only the hill side before producing excellent wine (or fruit, or wheat, etc. ..) now produces energy. With a less rigid bureaucracy
we could probably do the same, or slightly less, paneled i tetti delle case, le pensiline degli autobus ecc... e potremmo ancora gustarci il vino prodotto dalla collina. Insomma avremmo sfruttato quelle tare del territorio già presenti invece di crearne di nuove.
A mio avviso il problema dell'occupazione del terreno agricolo, da parte degli impianti fotovoltaici, non è affatto trascurabile.
Un impianto come quello della foto ( se cliccate accedete all' articolo da cui l'ho tratta ) occupa poco meno di 67.000 metri quadri. L'equivalente di 17 giornate agricole piemontesi e mezza. In questo caso si è trattato del recupero di una cava d'inerti dismessa ( ma ne poteva comunque uscire un frutteto o una vigna), ma è chiaro che col diffondersi plant of this size the risk to the region and for the same food production is high. How then to reconcile
requiring regular produce energy (as clean as possible) with the preservation of agriculture and land?
My idea I mentioned above. While I understand that there will always need large facilities, I believe we should give space to produce their own mini and that this can be done only deburocratizzando procedures. On the other hand it takes legislation to prevent the looting of valuable areas, which are a collective good, by those who have huge amounts of capital.
This can not, however, regardless of the spread of an education savings energetico. Altrimenti nemmeno ricoprire tutta la pianura padana di pannelli fotovoltaici e le Alpi di generatori eolici, risolverà il problema.
