AGAINST NUCLEAR ENERGY SOURCES: WHO WINS ?

I hope to be able to stimulate your interest and curiosity 'with the challenge of photovoltaics published a few days ago. Let's pretend now many Italians start (actually 'in 2009 there' was already a boom) to install facilities to go-go. All these mini photovoltaic implanted, will help anything? Obviously, our government and all others interested in promoting nuclear power say it is not 'can only achieve energy independence with renewable sources. I refer you to the post below on 'Energy and on wind energy for any of the information in the most' down to this seemingly a comparison of renewable sources.

Now let's do the math for dummies:

1. in Italy are now about 340000GWh (Gigawatt hour) of energy per year (source: Wikipedia ). This number represents all the energy consumed in Italy (including lost for the transport 20000GWh which amounts to approximately 6% of the total. Only to produce energy wasted in transporting nuclear power plants are about 3!)
2. how many rooftops are there in Italy? Let's say at least 15 million of houses, warehouses etc.
3. admit that only 30% of the roofs can be used for various reasons (not 'property' of those who live, not 'correctly exposed oe' shady etc. Etc..) This means that there are about 4.5 million roofs "papabili"
4. surface average user of any roof exceeds 60 square
5. panels with current 8mq need to get a peak power of 1kW. This means that every roof 'average' can have an installed capacity of about 7.5Kwp that in a year generates an average 8000KWh
6. energy potentials if the 30% of available roof and installing an 'then equal 36000GWh energy equal to about 6 nuclear power plants and more than 10% of national demand.
7. do now count in another way. We start from the current situation: the GSE (Energy Services Manager) dichiara che ad oggi (ultimo aggiornamento 29 ottobre 2010) sono installati in Italia quasi 110 mila impianti fotovoltaici per una potenza di oltre 1700MWp. Questo vuol dire che tutti gli impianti attualmente in esercizio producono mediamente 2000 GWh all'anno pari allo 0.6% del fabbisogno netto. Quanti sono in percentuale i tetti attualmente utilizzati? Bhe direi praticamente 0.00% dei tetti disponibili. Immaginiamo di arrivare ad un Milione di impianti cioe' meno del 10% dei tetti disponibili. Questo ci farebbe passare dagli attuali 1700MWp dei 110000 impianti gia' installati a circa 13000MWp con una produzione media di oltre 15000GWh, pari a quasi il 5% dell'intero fabbisogno nazionale.

Questi due diversi calcoli (il former being more 'ambitious from the number of roofs potentially available, the other more' conservative starting from real data of existing production) lead to comparable results. And 'quite realistic to reach a domestic production to cover from 5% to 10% of national demand.

In all these accounts, we have not seen that over the roofs of houses and capannonni, you may install facilities on land.

I would like to complete the picture by adding some data available on the network on the production of energy from renewable sources :

1. Hydroelectric 47000GWh 14.6% of the total requirement
2. Wind 6700GWh
2.1% 0.6%
3. Photovoltaics 2000GWh
4. Biomass 6500GWh 2.0%

============== ========================

The total '62,200 GWh and that' 20% of total energy requirements.

We said before that only the PV could rise from 0.6% to 5%, wind could, according to estimates by some experts to arrive safely at 20000GWh in 2015, which would weighing 6%. Let the current stable biomass 2%.

These estimates then lead to the following values \u200b\u200bfor 2015:

Hydroelectric 47000GWh 14.6% of the total requirement

1. Wind 20000GWh
6.2% 4.7%
2. Photovoltaics 15000GWh
3. Biomass 6500GWh 2.0%

The total energy from renewable sources could easily reach 27% of total needs.

you still believe that nuclear is the answer to energy needs? Until next time ...
