Nomina Energy Manager 2018

Con la Legge 10 del 1991 l’italia si era data uno strumento straordinariamente potente per introdurre massicciamente il tema dell’efficienza nel sistema economico. In particolare la legge individuava la necessità di avere figure professionali dedicate al tema energetico e poneva in capo alle aziende con consumi elevati (più di 10.000 TEP per le aziende industriali e più di 1.000 TEP per tutte le altre) l’obbligo di nominare il Responsabile per l’Uso Razionale dell’Energia, brevemente chiamato Energy Manager.
Questa impostazione rimane valida anche oggi: le aziende sono tenute alla nomina dell’Energy manager entro il 30 aprile di ogni anno e alla comunicazione della nomina al FIRE, tramite il portale NEMO.
La verifica dell’obbligo va fatta sommando tutti i consumi di ogni ragione sociale per tutte le sedi e filiali presenti sul territorio italiano: i diversi vettori energetici vanno convertiti in Tonnellate Equivalenti di Petrolio (TEP) secondo i fattori di conversione fissati nella circolare MISE del 18/12/2014.
Ve ricordato che le aziende che nominano un energy manager hanno anche alcune facilitazioni nell’ottenimento degli incentivi, come ad esempio la possibilità di presentare direttamente progetti per l’ottenimento dei TEE senza passare per ESCo certificate

About Energy Production

Immagine correlataMany qualify electricity from solar panels or wind mills, in a poetical mode, as free energy. There is no such a thing as free energy. It is renewable, but not free. It requires a large energy investment to produce solar panels or wind mills. It is imperative to use the proper tools to analyze any of the so called renewable sources of energy and dispel the notion that they represent free energy. The objective of those renewable sources is to have a positive future flow of output energy, and that flow of renewable energy should be able to pay the initial investment in non renewable energy in a short period of time, say a maximum of 3 years. This standard indicates that we have a real innovation. Any Government financial support does not change the reality of our objective, fast payback of the energy investment. This is the only objective we should have for a measure of reasonable sustainability and cut our dependency on foreign oil. As you can deduct, this definition of sustainability is independent of the price of oil, as it should be. Let’s check the situation of the three most common projects for renewable sources with the standard mentioned above. 1.Ethanol: The future flow of renewable energy is negative. There is nothing left to pay for the humongous required energy investments-1 Gallon of ethanol, uses 1.85 Gallons of oil- If we do nothing, we will be better off in terms of energy consumption and emissions now and in the future. The government support, with all their financial help, cannot change the negative energy balance and the enormous increase in present emissions. Our goal is not fulfilled. 2.Wind Mills: The future flow of renewable energy is positive. However the very large investments in energy to engineer and build the units, including power lines, have an energy payback beyond 30 years. This investment does not avoid the investment in carbon, gas, or nuclear power plants to cover the ~70% of the time they are not producing electricity. We are increasing dramatically the power consumption and emissions as we build the units now, for a meager yearly renewable volume of power. . Our goal is not fulfilled 2.Solar panels: The future flow of renewable energy is positive. The pay back for the initial energy consumption is beyond 50 years. Solar panels produce energy in average ~20% of the time. Any standard technology, let’s say small generators consuming natural gas, cost 1/30 of the energy cost of a solar panel for an equal total output. We seem to be digging our own grave with gusto. None of those projects comply with the most elementary energy objective we have as a country; on the contrary, they produce a considerable spike of energy usage now, that could be avoided, and I doubt that they will ever have a proper pay back in created energy. There is no wealth creation in these activities, no energy savings, only an immediate transfer of money from the Taxpayers to somebody else, destroying other Industries in the meantime. Due to all kind of government money injected into these projects, and the high price of oil, money could be made. But if the price of oil goes below a certain threshold, boom, the project is no longer viable. See T. Boone Pickens suspending his wind mill project because oil went below US$60. Or the several bankruptcies in ethanol due to the higher price of corn in spite of all the subsidies! Millions of barrels of oil that we cannot afford to loose, thrown to the wind. None of those programs complies with cutting CO2 emissions, a suspected objective anyway. They make our dependence of foreign oil much worst, not better, using considerable high level engineering resources for naught. There are enormous opportunities in energy savings and production in many Industries, with a positive balance of energy consumption and paybacks anywhere from 4 months to one year.

Workshop “Vendere il valore”

Il giorno 23 maggio si è svolta a Stezzano presso il polo Schneider il Workshop “Vendere il valore”: una lezione introduttiva tenuta dal dott. Restori sulle nuove figure e nuove opportunità nel campo dell’efficienza energetica.

L’Ecobonus 2017

La Legge di Bilancio, approvata in Parlamento a fine 2016, anche quest’anno punta a sostenere economicamente modalità produttive o forme di consumo che riducono l’impatto ambientale. Il cosidetto “ecobonus” contiene delle interessanti opportunità nel campo dell’efficientamento energetico per privati e imprenditori.

Ecobonus nella Finanziaria 2017

Viene prorogato l’Ecobonus, detrazione fiscale per la riqualificazione energetica, e la proroga vale fino a 2021, con delle percentuali di detrazione tra al 70% e al 75% per i condomini. Per le abitazioni private la detrazione al 65% viene estesa al 2017.

Bonus ristrutturazione edilizia nella Finanziaria 2017

Il Bonus concesso alle ristrutturazioni è prorogato fino al 2017 con una detrazione del 50%. Rimane valido per il 2017 il Bonus Mobili con la possibilità di detrarre le spese di acquisto di mobili al 50%.

Bonus Alberghi nella Finanziaria 2017

Il Bonus Alberghi, prorogato fino al 2018 permette di detrarre le spese per il 65% della spesa.

Sisma Bonus nella Finanziaria 2017

Per il Sima Bonus vengono confermate le “scale” di detrazione che si applicano a seconda della classe antisismica raggiunta dopo l’intervento: i parametri da rispettare sono 50, 70, 80% per le case e 50, 75, 80% per i condomìni.

 

Non sono state approvate alcune detrazioni che erano state inizialmente ventilate:

– credito d’imposta 65% per le spese di classificazione sismica,

– bonus 65% per la bonifica amianto,

– possibilità della cessione del credito d’imposta anche per le opere in singole unità abitative,

– detrazione 50% per la sistemazione a verde di aree scoperte di pertinenza,

– ampliamento del perimetro della cessione del credito di imposta dai soli fornitori alle banche, per l’ecobonus e il sisma bonus.

 

Il grafico più importante

6Whenever I show up at a new client’s, the first thing they pass in front of me is their “Energy Profile,” or “Energy Report,” or (and this is the most accurate title) “Energy History.” These plots show some form of energy consumption over some time period, usually electricity and natural gas over the course of a year. This is a logical place to start, and you can acquire some real insights.

Take a look at the chart on the left here. (This is all fabricated data by the way.) This chart shows energy consumed through a typical week for an injection mold machine making plastic chairs. So what do we learn? Well, clearly something different happened on Friday. Maybe there was an early shut down, maybe operators were just paying less attention. Something seems to have been happening on Wednesday as well. These definitely call for some investigation. If nothing else, we’ll understand the weekly cycle better.

But, really, this chart doesn’t give us any sense of how our production rate drives our energy consumption. In ISO 50001 parlance, we would say that Time is NOT a Relevant Variable. Our energy consumption does not change because Time is passing! Our energy consumption changes because OTHER THINGS are changing. In this case, it is Production.

Take a look at the second chart. Oh my! Now we seem to be getting some useful information! We can see now, not only that energy consumption is proportional to Production, but we can see HOW it is related to Production. We can actually determine the mathematical relationship between the two. That means that given Production projections, we can compute Energy Consumption projections! Isn’t that a grand piece of information to pass to your CFO? You can also now deliver an estimate of marginal energy intensity per chair produced. Be careful now! You are making yourself profoundly useful to your top management!

Finally, you can identify a key insight for your own energy improvement efforts. This relationship tells you how much of your energy consumption is related to Production, and how much is Baseload. I’ve seen places where a simple analysis such as this revealed that the Baseload was over half of their monthly energy consumption! They had been working diligently on reducing energy consumption in their Production processes, but it turned out that the Baseload was the elephant in the room.

They asked me, “Why is it so much?” I said that I surely didn’t know, but that they had better find out.

(And if you’d like to see what this feels like from the elephant’s point of view, click here: https://twitter.com/PaulBirkeland/status/240609468910563328/photo/1)
