Animali_che_Ridono__006_Muli

Nessuno si stupisce più di tanto che cessati gli incentivi statali le energie alternative in Italia stiano ristagnando.

E poi iniziano a mordere le spese di manutenzione e rinnovo degli impianti, che non son cifre da poco.

Ma ciò che lascia sempre più perplessi è la levità espressiva dei supporter.

«sono circa un milione gli impianti tra elettrici e termici installati»

*

«creazione di 2,7 milioni di posti di lavoro»

* * * * * * *

A parte il fatto che in italiano ‘creare‘ significa trarre dal nulla, prerogativa della Divinità non certo della stirpe umana, 2.7 milioni di nuovi posti di lavori sono più del 10% dell’attuale forza lavoro italiana.

Per promettere di generare 2.7 milioni di posti di lavoro serve un fegato grosso così.

Poi, essendo il numero degli impianti eguale ad un milione, ci sarebbero tre addetti per ogni impianto: un numero fantasmagorico.

Poniamo anche di pagarli una miseria, 1,500 euro al mese, 18,000 euro l’anno.

Ogni impianto dovrebbe sobbarcarsi l’onere di 48,600 euro l’anno per mantenere i nuovi posti di lavoro.

Roba da pazzi.

Poi certa gente si lamenta che non li si stia più a sentire.


Ansa. 2019-05-14. Cala dopo 12 anni la produzione di energia pulita in Italia

ROMA – Cala per la prima volta dopo 12 anni, in Italia, la produzione di energia da fonti rinnovabili – in particolare solare, eolico e bioenergie – e vanno lentissimi gli investimenti nel settore, sia perchè non ci sono più incentivi a sostenerlo, sia per le barriere autorizzative ai progetti nei territori. Lo rileva Legambiente nel rapporto ‘Comuni rinnovabili 2019’, sottolineando che “lo sviluppo delle rinnovabili in Italia è praticamente fermo”, mentre “molto di più dovremo fare per stare dentro l’Accordo di Parigi sul clima”, fra i cui obiettivi c’è la riduzione del 55% delle emissioni di gas serra al 2030. I benefici sarebbero pari a 5,5 miliardi di euro all’anno e alla creazione di 2,7 milioni di posti di lavoro (secondo una ricerca realizzata da Elemens per Legambiente).

Tuttavia, nella nostra Penisola sono circa un milione gli impianti tra elettrici e termici installati in tutti i comuni italiani. Grazie al mix fra fotovoltaico, solare termico, mini idroelettrico, eolico, bioenergie e geotermia distribuiti su tutto il territorio, sono 3.054 i comuni diventati autosufficienti per i fabbisogni elettrici e 50 per quelli termici, mentre sono 41 le realtà già rinnovabili al 100% per tutti i fabbisogni delle famiglie.

Il problema è semplicissimo.

Come si conviene ai liberal socialisti, l’ideologia impone il passaggio dal nucleare e dal carbone alle energie alternative.

Tralasciamo volutamente i problemi di costo, che però per un’economia quasi stagnante potrebbero essere non da poco.

Il sud della Svezia è la zona ad alta concentrazione industriale, e quindi richiede energia nelle ore lavorative. Non a caso le centrali atomiche sono locate nel sud della Svezia, così come quelle a carbone ed a gas naturale.

Ma al sud i venti sono deboli, capricciosi ed incerti: senza vento non si genera corrente elettrica.

Gli svedesi hanno quindi optato per mettere gli impianti eolici nel nord del paese. Le turbine in grado di lavorare a basse temperature sono costose, sicuramente sì, e richiedono anche grandi manutenzioni, ma cosa non si immolerebbe sull’altare delle energie alternative.

Resta il problema, a quanto sembrerebbe alquanto scotomizzato dagli ingegneri progettisti, di come poter portare l’energia prodotta al nord fino al sud industrializzato.

*

Energia. Il problema degli elettrodotti a lunga distanza. Le dissipazioni.

«First, electricity travels on long-distance, high-voltage transmission lines, often miles and miles across country. The voltage in these lines can be hundreds of thousands of volts. You don’t want to mess with these lines.»

*

«Why so much voltage? To answer this question, we need to review some high school physics, namely Ohm’s law. Ohm’s law describes how the amount of power in electricity and its characteristics – voltage, current and resistance – are related. It boils down to this: Losses scale with the square of a wire’s current. That square factor means a tiny jump in current can cause a big bump in losses. Keeping voltage high lets us keep current, and losses, low»

*

«Energy lost in transmission and distribution: About 6% – 2% in transmission and 4% in distribution – or 69 trillion Btus in the U.S. in 2013»

*

Non si è infatti “liberi” di poter costruire una centrale elettrica dove si voglia: occorre piazzare gli impianti ove i venti siano persistenti e non troppo veloci. In altri termini, le sedi di produzione sono quindi obbligate.

Questo comporta necessariamente linee di trasmissione anche molto lunghe: in taluni casi si parla di migliaia di kilometri. La dissipazione in questi casi aumenta a dismisura.

Si pensi soltanto al trasferimento di energia dal Mecklenburg-Vorpommern al Bayern: sono circa 700 kilometri.

La dissipazione è enorme: oltre il cinquanta per cento.

*

Siamo estasiati che gli ingegneri svedesi abbiano riscoperto la legge di Ohm.

Ma saremo ancor più esaltati quando avranno studiato un minimo di contabilità dei costi: rifare il grid svedese costerà non uno ma tre occhi delle testa.

Gli svedesi avrebbero un gran bisogno di passare uno dei loro famosi inverni al buio e senza riscaldamento ed acqua calda.


Bloomberg. 2019-05-03. Sweden’s Lack of Electricity Capacity Is Threatening Growth

A shift toward renewables is overwhelming the nation’s grid, leaving a potential Olympic Games in 2026 relying on reserve generators.  

*

Global trade wars and weakening export markets are not the only potential dampers on Sweden’s growth. There’s also a homegrown problem: a lack of power capacity. 

The dire situation stems from the closing of the nation’s oldest reactors and a shift to wind at a time when the grid is already struggling to keep up with demand in major cities. The shortage, which impacts the nation’s main urban areas, is threatening everything from the rollout of a 5G network in the capital to investments in giant data halls and new subway lines. It could even derail Stockholm’s bid for the 2026 Winter Olympics.

It’s a stark change from the decades of cheap, surplus electricity that propelled the Nordic region’s biggest economy into one of the richest and most industrialized nations in the world. Now, electricity supplies in urban areas can’t keep up and that could exacerbate a slowdown already impacted by global uncertainty and Brexit.

“Citizens and companies are worried, irritated and even angry,” said Jonas Kamleh, a strategist for the City of Malmo, the nation’s third biggest. “How could this situation arise in the engineering nation of Sweden?”

The answer is a very ambitious green agenda. Sweden is halfway through a plan to replace the output from four reactors in the industrial south with thousands of wind turbines in the north. But grid connections, some dating back to the 1950s, aren’t up to scratch so the power isn’t shipped to where it’s really needed. And to make matters worse, city demand is surging at a faster-than-expected pace because of the electrification of everything from transport to heating.

The capacity issues could hit an economy already heading south after years of strong growth buoyed by household spending and exports. The Swedish National Institute of Economic Research said last month the economy is slowing and forecast GDP growth of just 1.5 percent this year compared with 2.3 percent in 2018.

The abundance of carbon-free power from hydro, nuclear and wind has attracted billions of dollars in the past decade from some of the world’s biggest companies from Amazon.com Inc. to Facebook Inc. and Microsoft Corp. With the major urban areas out of bounds, it will be harder to attract the same level of investment in the future. 

“A lot of businesses are rather energy-intensive and if we do not have enough capacity there is a potential chance it will impact long-term growth,” said Ake Gustafsson, senior economist at Swedbank AB. “Computer giants such as Amazon are global companies that can place their data centers anywhere.”

Cina. Energie alternative solo se più economiche. Fine delle sovvenzioni.

L’annuncio dato dalla Cina è sobrio, esaustivo e sembrerebbe essere con i piedi bene sulla terra.

China: No Wind Or Solar If It Can’t Beat Coal On Price

«China has said it will not approve wind and solar power projects unless they can compete with coal power prices.

Beijing pulled the plug on support for large solar projects, which had been receiving a per kWh payment, in late May. That news came immediately after the country’s largest solar industry event and caught everyone by surprise.

Officials are understood to have been frustrated at seeing Chinese suppliers and engineering firms building solar projects overseas that delivered electricity at prices far below what was available back home.

The country also has its own issues with grid logjams. These have caused power from wind and solar projects to be wasted due to a lack of capacity on the network to transmit and distribute it. In 2017 12% of wind generation and 6% of solar was curtailed.

In the plans announced on Thursday, the National Development and Reform Commission (NDRC), the top strategic planning authority, and the National Energy Administration (NEA) set out a series of conditions under which new solar and wind projects would be approved from now till the end of 2020.

Chief among these is that the price matches or undercuts the national coal benchmark, something that happened for the first time ever just last month.

Projects will also have to show that the grid can handle their output. Technical specifications will ensure that the highest standards are met on that front.

Local governments have been told they are free to offer their own subsidies to projects if they wish.

In the past, provincial authorities have spent heavily to bankroll uncompetitive solar manufacturers. Thursday’s announcement warned that any attempt to use project subsidies to invest in “local factories” or to make the use of locally made components a condition of the subsidy.

Also included in the wide-ranging changes is the introduction of a green certificate scheme. A small trial of such a scheme was undertaken in 2017. It would work in a similar way to renewable energy certificates schemes in the U.S. and elsewhere. A certificate is created for each unit of electricity generated. These are then traded among utilities who may have targets to meet as determined by regulators or purchased by an end user to demonstrate their use of “clean” power. Details on the mechanics of the certificate scheme have not yet been released.»

Se è vero che la corrente elettrica è prodotta nelle centrali, sarebbe altrettanto vero ricordare come da queste debba essere portata ai consumatori tramite gli elettrodotti, che dissipano energia.

Il costo deve essere contabilizzato su quanto alla fine arriva al consumatore.

Non solo, ma si deve anche tener conto del costo di impianto, di manutenzione e di rinnovo.

In linea generale, più le centrali sono piccole e sparpagliate e minore è la necessità di disporre di reti a lunga percorrenza: maggiore la lunghezza dell’elettrodotto, maggiore la dispersione

Della corrente eolica prodotta sul Baltico ne arriva in Baviera, luogo di consumo industriale, appena il 50%. Questo vuol dire raddoppiare i costi per kwh.

Infine, e cosa non da poco, l’eolico produce corrente solo quando tira vento ed il solare solo quando c’è il sole.

Queste centrali entrano in produzione a capriccio meteorologico, non dietro esplicita richiesta dei consumatori.

Per ultimo ma non certo per ultimo, quando queste centrali alternative entrano in funzione immettono grandi quantità di energia nel grid, che se ne va regolarmente in sovraccarico.

Eolico. Anche TransAlta chiude i battenti dopo 23 anni di perdite.

Giuseppe Sandro Mela.

2017-06-14__Calgary__001

Alla fine la dura realtà ha ragione su qualsiasi delirio schizofrenico.

La realtà massacra le ideologie: le è sufficiente lasciarle libere di fare. Si suicidano da sole.

Peccato che nel caso delle energie alternative questo Götterdämmerung bruci sulla pira di una montagna di soldi pubblici, di soldi del Contribuente.

Avevamo già annunciato la problematica in un recente articolo:

Energie alternative e sussidi di stato. Fallimenti, manutenzione e ricambi.

In sintesi. Ogni fallimento di una ditta produttrice lascia gli impianti in essere senza manutenzione specializzata e senza pezzi di ricambio: gli impianti di produzione industriale sono così destinati e diventare in breve talmente anti – economici da dover chiudere portando i libri in tribunale. E se poi lo stabilimento di produzione era stato messo in una zona senza vento, il fallimento è garantito.

«The oldest commercial wind power facility in Canada has been shut down and faces demolition after 23 years of transforming brisk southern Alberta breezes into electricity — and its owner says building a replacement depends on the next moves of the provincial NDP government.»

*

«TransAlta Corp. said Tuesday the blades on 57 turbines at its Cowley Ridge facility near Pincher Creek have already been halted and the towers are to be toppled and recycled for scrap metal this spring»

*

«The company inherited the now-obsolete facility, built between 1993 and 1994, as part of its $1.6-billion hostile takeover of Calgary-based Canadian Hydro Developers Inc. in 2009.»

*

«TransAlta is very interested in repowering this site. Unfortunately, right now, it’s not economically feasible»

*

«We’re anxiously waiting to see what incentives might come from our new government. . .»

* * * * * * *

Ci sono tutti gli elementi base che alimentano il ‘clima’.

Dapprima vi sono stati enormi risorse impiegate in ricerca e sviluppo per l’eolico. Tutti finanziamenti a fondo perso. Tutti a lanboratori liberal, ovviamente.

Poi ci sono state le sovvenzioni di stato per impiantare la produzione di eolico a Calgary. Altri fiumi di denaro pubblico. Ditta produttrice liberal anche essa.

Poi, l’impianto rilevato per una cifra stroboscopica: milleseicento milioni di dollari. Con sovvenzioni pubbliche. Elargite da un governa liberal democratico, manco a dirlo.

Poi il dramma della manutenzione:

«The lifespan of the original turbines was 20 years, but the company was able to keep them running in part by cannibalizing nine similar towers from TransAlta’s Taylor wind farm near Magrath in southern Alberta, retired in 2012, Oliver said.»

Già: le turbine hanno vita media di venti anni. E se le ditte produttrici falliscono, risulta essere impossibile la manutenzione degli impianti.

Poi, il grottresco:

«when it’s windy is quite low, so there’s just not the return on investment»

Ma chi mai avrebbe potuto immaginarselo che senza il vento le turbine eoliche non producono nulla?

Chi mai avrebbe potuto comprendere un concetto così raffinatamente sofisticato? Non ci si venga a dire che i supporter delle energie alternative siano in buona fede. Al massimo possiamo concedere loro di essere schizofrenici.

Alla fine proprio non ce la si fa più: finite le sovvenzioni.

Ma sono anche recidivi:

«We’re anxiously waiting to see what incentives might

come from our new government. . .»

Vorrebbero ancora baiocchi pubblici per foraggiare i parassiti.

Avete letto bene: 16.9 trilioni Usd, ossia 16,900 miliardi Usd, tutti presi dalle tasche dei Contribuenti.

* * * * * * *

Conclusione.

Nulla da ridire sul fatto che il mito delle energie alternative sia un delirio schizofrenico o, in unica alternativa, il manto sotto il quale si mimetizzano i truffatori.

Non si vede però per quale motivo il Contribuente debba alimentare tale delirio con le tasse che gli sono cavate via dagli stati, per foraggiare poi le tasche dei liberal democratici.


Calgary Herald. 2016-03-15. Oldest commercial wind farm in Canada headed for scrapyard after 23 years

The oldest commercial wind power facility in Canada has been shut down and faces demolition after 23 years of transforming brisk southern Alberta breezes into electricity — and its owner says building a replacement depends on the next moves of the provincial NDP government.

TransAlta Corp. said Tuesday the blades on 57 turbines at its Cowley Ridge facility near Pincher Creek have already been halted and the towers are to be toppled and recycled for scrap metal this spring. The company inherited the now-obsolete facility, built between 1993 and 1994, as part of its $1.6-billion hostile takeover of Calgary-based Canadian Hydro Developers Inc. in 2009.

“TransAlta is very interested in repowering this site. Unfortunately, right now, it’s not economically feasible,” Wayne Oliver, operations supervisor for TransAlta’s wind operations in Pincher Creek and Fort Macleod, said in an interview.

“We’re anxiously waiting to see what incentives might come from our new government. . . . Alberta is an open market and the wholesale price when it’s windy is quite low, so there’s just not the return on investment in today’s situation. So, if there is an incentive, we’d jump all over that.”

In February, TransAlta president and chief executive Dawn Farrell said the company’s plans to invest in hydroelectric, wind, solar and natural gas cogeneration facilities in Alberta were on hold until the details of the province’s climate-change plans are known.

“We cannot make any major investment decisions in this market until we have more clarity around the policy environment and the policy recommendations turn into actual law and we know what the market is actually going to be like,” she said.

Last November, Premier Rachel Notley’s government vowed that coal-fired power plants would be forced to shut down or be emissions-free by 2030. Coal power companies in Alberta, including TransAlta, are looking for compensation.

Jean-François Nolet, vice-president of policy and communications at the Canadian Wind Energy Association, said Tuesday his organization has been included in the NDP government’s consultations and is optimistic that changes will be made to encourage wind power growth.

“What the investors need to see is more certainty in the market,” he said, adding that it “just makes sense” that a wind farm such as Cowley Ridge that is already connected to the grid and has a proven wind resource is rebuilt to continue to provide renewable energy.

Alberta has the third-largest installed wind energy capacity in Canada with 1,500 MW and 958 turbines, CanWEA says.

“Designing Alberta’s first comprehensive energy efficiency program under our climate leadership plan will take time to get right,” Environment and Parks Minister Shannon Phillips said in an emailed statement on Tuesday.

“That work is underway and will continue in the months leading up to the phase-in of an economy wide carbon price beginning in 2017.”

Unlike sleek modern turbines balanced on thick hollow metal stalks, Cowley Ridge’s turbines near Pincher Creek were built on 24.5-metre-tall steel lattice towers. The first phase was commissioned in 1993 and Phase 2 was added the following year. In October 2000, five more similar used towers were acquired and added.

Oliver said safety was a major factor in deciding to decommission.

“When you’re climbing that ladder (inside the newer tubular towers), you’re not exposed to the wind and the rain and the snow,” said Oliver. “But this lattice-style tower, you’re exposed to all of that.”

He estimated that 680,000 kilograms of metal will be recovered and recycled. The teardown crew will have to wait until winds drop below 25 km/h before dismantling can proceed.

Landowners have asked that some of the gravel service roads be left in place to allow new turbines — and new rent and revenue-sharing sources — to be built in the future, he said.

The lifespan of the original turbines was 20 years, but the company was able to keep them running in part by cannibalizing nine similar towers from TransAlta’s Taylor wind farm near Magrath in southern Alberta, retired in 2012, Oliver said.

He said there’s only one other wind farm still in operation in North America using the same technology and it’s becoming impossible to find replacement parts. TransAlta has known for some time that Cowley Ridge would have to close — a decision was made in February.

About six people work on Cowley Ridge from about 30 people in the Pincher Creek office that will continue to operate Cowley North and Summerview wind farms.

“It’s an iconic landmark in the Pincher Creek area, there’s a lot of interest,” said Oliver.

“It’s bittersweet. The fellows who work on the site, you know, they’ve put a lot of energy and heart into keeping the site running. When it was time to pull the plug and pause all the turbines, the guys the week leading up to it had just got a bunch of turbines back on line that had been down for a while.

“So we were making progress.” 

 


Watts Up With That. 2017-06-14. Wind power fails in Canada – a 23 year life span not likely to be replaced

The oldest commercial wind power facility in Canada has been shut down and faces demolition after 23 years of transforming brisk southern Alberta breezes into electricity — and its owner says building a replacement depends on the next moves of the provincial NDP government.

TransAlta Corp. said Tuesday the blades on 57 turbines at its Cowley Ridge facility near Pincher Creek have already been halted and the towers are to be toppled and recycled for scrap metal this spring. The company inherited the now-obsolete facility, built between 1993 and 1994, as part of its $1.6-billion hostile takeover of Calgary-based Canadian Hydro Developers Inc. in 2009.

“TransAlta is very interested in repowering this site. Unfortunately, right now, it’s not economically feasible,” Wayne Oliver, operations supervisor for TransAlta’s wind operations in Pincher Creek and Fort Macleod, said in an interview.

“We’re anxiously waiting to see what incentives might come from our new government. . . . Alberta is an open market and the wholesale price when it’s windy is quite low, so there’s just not the return on investment in today’s situation. So, if there is an incentive, we’d jump all over that.”

I’ll bet they would. Does anyone need any more proof that wind power just isn’t economically feasible on large scales without subsidies?

Coal and nuclear plants last longer and provide far more power…and production isn’t tied to the vagaries of wind and weather.

Riassumiamo in sintesi il problema.

Il nodo è il rapporto prestazioni/costo.

– I paesi dell’Unione Europea hanno investito nell’eolico denaro pubblico con cui si sarebbero potute costruire un po’ più di cento centrali nucleari, che possono produrre corrente elettrica anche senza luce e senza vento.

– L’energia alternativa senza i continui finanziamenti pubblici a fondo perso costerebbe circa quattro volte quella generata da centrali termiche od atomiche, tenendo conto anche delle dissipazioni lungo le linee.

Ci si rende conto dell’enormità degli investimenti effettuati per ottenere un risultato così antieconomico: un evento che non si era mai visto nemmeno nella vecchia Unione Sovietica che, lo si dica apertamente, non brillava certo per razionalità produttiva, ed infatti è implosa.

Ci si rende anche conto che tutto questo fiume di denaro pubblico sia confluito sui conti correnti dei socialisti europei, consentendo loro di vivere in una serena agiatezza.

Se non fossero stati spesi tutti questi fondi pubblici nelle energie alternative, il debito sovrano dei paesi afferenti l’Unione Europea sarebbe stato ridotto di un buon terzo e non sarebbe stato necessario che l’Ecb fosse stata costretta a varare il QE.

Ripetiamo. Con lo stesso investimento si sarebbe potuta garantire la quasi totalità dei consumi elettrici dell’Unione Europea.

Ce lo si ricordi al momento di andare a votare.

Non si trova quindi motivo alcuno per cui questo stato di cose debba proseguire.

Francia. Nucleare. Via i socialisti, via le rinnovabili.

Lo sapevano anche le pantegane di Parigi. Ma non lo si poteva dire a voce alta e chiara.

Chi settant’anni or sono avesse osato dire che gli Ebrei erano brava gente sarebbe finito in campo di sterminio a meditare sul fatto che non è mai prudente dire la verità sotto una dittatura.

Anche se questa verità fosse stata lampante.

Adesso che il partito socialista francese sta andando incontro all’estinzione, la gente inizia a tirare un respiro di sollievo ed a poter di nuovo dire che due più due fa quattro, e non quello che fa guadagnare il partito (socialista).

Riassumiamo.

(1). I tedeschi hanno speso un occhio della testa in aiuti di stato (soldi dei Contribuenti) per installare rinnovabili per una potenza 1.3 volte maggiore quella del nucleare francese, e questi impianti rinnovabili rendono non più del 25% – 30%.

In altri termini, i costi sono quattro volte tanti a parità di energia prodotta.

(2). Grande scoperta, da Premio Nobel per la fisica. Senza vento gli impianti eolici non producono nulla e senza luce gli impianti fotovoltaici diventano meri ornamenti architettonici inerti.

Ma chi mai avrebbe potuto immaginarsi una cosa del genere?? Chi mai??

E così, se non tirasse vento o fosse nuvolo nelle ore di punta, tutti al buio e tutti gli impianti industriali chiusi. Ecologicamente perfetti.

Solo la povera mente dei socialisti e dei verdi non ci sarebbe mai arrivata da sola.

 

Reuters. 2015-05-21. Renewables cannot replace nuclear in France yet : EDF exec

Renewable energy is far from being able to replace nuclear energy in France’s electricity mix, utility EDF’s head of nuclear said on Thursday.

Dominique Miniere said a 2015 study by state energy agency ADEME, which showed France could switch to 100 percent renewable energy by 2050 for the same cost as relying on nuclear for half of its power, was not realistic.

“A certain number of points in that study are not based on technological realities,” EDF executive committee member Miniere told reporters in reply to a question.

Energy minister Segolene Royal delayed publication of the controversial study until after parliament voted last summer for the energy transition law, which pledged more support for renewables but maintained reliance on the atom for about three quarters of French electricity.

“We do not believe in a 100 percent renewables mix by the horizon (ADEME) indicates. However, we want to extend the lifespan of our reactors in order to allow a gradual increase of renewables in the mix,” Miniere added.

He said replacing nuclear with renewables too quickly, citing Germany as an example, ends up boosting carbon emissions from fossil fuel.

He said Germany’s 80 gigawatt installed renewable energy capacity is about 1.3 times installed French nuclear capacity, but produces three to four times less power per year because solar and wind operate only about 15 percent of the time compared to about 80 percent for nuclear.

Miniere said that in 2010 French power production emitted 10 times less carbon than Germany’s, but that as Germany has switched on more coal and lignite plants to compensate for closed nuclear reactors, France now emits 30 times less carbon.

Miniere – whose name was not on a letter of EDF engineers supporting EDF’s project to build nuclear reactors in Hinkley Point, UK – denied he did not back the project.

He said the letter was signed by staff who had worked on Hinkley Point or EDF’s new nuclear plant in Flamanville, France.

“These people had the credibility to sign,” he said, adding there was no internal opposition between managers of the existing fleet and managers in charge of new nuclear projects.

EDF’s unions and some of its senior staff want the company to delay Hinkley Point by several years in order to avoid further stretching EDF’s balance sheet.
