As the article below says:
‘The tiny contribution of wind and solar to grid electricity cannot make up for the loss of more traditional electricity sources due to low prices.’

One of many problems with renewables unfortunately. And its even more unfortunate when those problems seem to be getting ignored by those in charge of our electricity supplies.

Intermittent Renewables Can’t Favorably Transform Grid Electricity
Our Finite World
Gail Tverberg
31 August 2016

Many people are hoping for wind and solar PV to transform grid electricity in a favorable way. Is this really possible? Is it really feasible for intermittent renewables to generate a large share of grid electricity? The answer increasingly looks as if it is, “No, the costs are too great, and the return on investment would be way too low.” We are already encountering major grid problems, even with low penetrations of intermittent renewable electricity: US, 5.4% of 2015 electricity consumption; China, 3.9%; Germany, 19.5%; Australia, 6.6%.

In fact, I have come to the rather astounding conclusion that even if wind turbines and solar PV could be built at zero cost, it would not make sense to continue to add them to…

America has some perfect examples of what not to do, if it wants to remain an industrial and manufacturing power-house, with a standard of living that much of the World can only envy.

South Australia has set the pace with spot prices that rocket in minutes from $70 per MWh to $2,000 to $4,000 and all the way to the regulated market price cap of $14,000 per MWh, every time wind power output collapses on a total and totally unpredictable basis.

And much of Europe is in the same boat: think Spain, Germany, Denmark and the UK.

From what’s coming out of the USA, Americans don’t seem that keen to follow the path set by countries facing social and economic disaster, thanks to their ludicrous attempts to run on sunshine and breezes.

Donn Dears LLC is among them.

Heard it before? Questions to be addressed include the economics of this type of project and the long-term reliability of the technology in corrosive seawater. Similar previous attempts have not got very far.

Scotland’s First Minister Nicola Sturgeon today launched a 398 MW tidal stream energy project, reports PEI. The MeyGen scheme is owned by Atlantis Resources, backed by £23m of Scottish government investment, and located in Scotland’s Pentland Firth.

A fully assembled 1.5 MW Atlantis tidal power turbine with foundations was unveiled today at a ceremony is Nigg before being loaded onto a jack-up vessel and transported to the MeyGen for installation.

UK electricity supply – approaching the cliff edge? [image credit: Wikipedia]


Utility Week highlights an expert’s view of the dire state of the UK’s electricity network, largely driven by the climate dogmatism of government policies. Urgent action is advised, with Brexit in mind.

UK Business and Energy secretary Greg Clark needs to “reset the balance between the market and the state” and avoid “more patching up of what he has inherited”, [Professor] Dieter Helm has said.

The energy sector is “not in good shape,” and is unable to fulfil the needs of a major industrial economy, “especially for one doing Brexit”.

Growing electricity demand, as heat and energy are electrified, will make the “current capacity margin of roughly zero even more alarming than it is now”, the Oxford economist said in a paper.

Seconds out, round 10 – or so it might seem in the Hinkley nuclear struggle. Who kept who in the dark [pun intended]? PEI’s Diarmaid Williams takes a ringside seat.

Five of the 17 board members who voted to approve a decision by EDF to press ahead with the development of Hinkley Point C nuclear power plant in England are now seeking a court annulment of that decision.

The board members, all union representatives, say they were not provided with information that was crucial to their decision on the day.

Note: for ‘energy’ read ‘electricity supply’ in this report from Utility Week on the UK’s crumbling National Grid.

The UK will need to invest an “eye-watering” £215 billion in its energy system by 2030 in order to replace ageing assets and decarbonise, analysis by Barclays Research has found.

As the country undergoes an “energy revolution” nearly half – £95 billion – will need to be spent on disruptive technologies such as renewables, battery storage and distributed generation.

Solar-Loaf-600-AEAEd Hoskins has sent me a summary of his latest post on ‘green energy’ profligacy, which well worth a click and read.

It seems that the UK with the least performant solar energy environment  in Europe has allowed to be invested about £30 billion with an output of less than 1 GW as and when the sun shines.

This amounted to a total of about   9.6GW nameplate solar installations yielding the equivalent of about 0.9GW of power, but only when the sun shines.  The capacity factor for Solar energy in the UK is only ~9%.  This is the least performant solar power in the whole of Europe.

Even though according to David Mackay DECC well understood that solar energy should never have been considered viable in the UK, the department still oversaw these huge continued expenditures and dispensed with about £19,000,000,000 in 2014 and 2015.  That amounted to more than the full cost of Hinckley Point C:  the wasted expenditure seems never to have been questioned or discussed.

A new paper published today by the Global Warming Policy Foundation (GWPF)  confirms suspicions that previous governments have misled the public about the impact of climate policies on businesses such as Tata Steel.

There are three main faults in government analysis:

 

  1. Instead of showing the impact of climate policies on profitability (Gross Operating Surplus), the government has compared policy costs to the total expenditure of a business, which is misleading. In 2014, for example, the sector had an operating surplus of £169m, yet energy costs were equal to 330% of that sum.

Is the world ready for organic flow batteries using extracts from rhubarb? PEI reports on some new electricity storage ideas hoping to save renewable energy from ultimate failure. ‘Holy Grail’ or wild goose chase – time will tell.

The US energy secretary, Ernest Moniz, believes the advances being made in storage technology means that the country will be completely decarbonised by the 2050s.

A global race, seen initially in Europe and the US is leading to a rapid acceleration in innovation that may dispense with the need for nuclear and thermal power by that time according to the technology’s backers, as the Achilles heel of intermittency will no longer impact on the overall effectiveness of renewables.

uk-piggy-bankResidents affected by fracking could be paid a proportion of the proceeds of shale gas projects, the government has suggested.

A shale wealth fund was unveiled in 2014 to set aside up to 10% of the tax proceeds from fracking to benefit communities in the UK hosting wells.

The PM is now considering paying the money directly to individual households instead of councils and local trusts.

The plan is one option due to be outlined in a consultation on Monday.

nuke-powerIn a surprise move, the UK govt has put the brakes on the Hinkley Point nuclear power contract. Yesterday, there was anticipation in the media that the directorate of EDF would approve the scheme. In the event, the vote was 10 to 7 in favour, though one director resigned beforehand.

Maybe the depth of the split on the EDF board has given the new UK government the jitters. In a brief two line statement this morning, the business secretary, Greg Clark, said the government would now examine all components of the deal and decide in the Autumn whether to go ahead, or not.

A judge upheld RSPB Scotland’s challenge to consent for turbines in the Firth of Forth and Firth of Tay.

Brian Wilson said the charity now “hold all the cards” over the schemes, which were to include hundreds of turbines.

Motoring in Norway

Motoring in Norway

Renewable energy has no hope of replacing the 90-odd million barrels of oil used daily around the world.

Robert Lyman looks at some of the inconvenient facts.

Friends of Science Calgary

Contributed by energy economist Robert Lyman @ July 2016

Environmentalists across Europe and North America seem determined to wage war on oil-fueled motor vehicles, including private cars, light trucks and heavier trucks used for freight. The most recent example of this is the announcement that Norway and the Netherlands, heavily influenced by the European Green Party, may ban car manufacturers from selling cars and light trucks fueled by gasoline or diesel fuel by 2025. It wasn’t enough to raise fuel taxes and carbon taxes to punishing levels; an outright ban was called for. The Environment Minister for Germany was quoted as saying that Germany might do the same, but quickly retreated from that after a strong public reaction.

This is all allegedly to “save the planet”, the often repeated mantra of those who believe in the theory that humans are causing catastrophic climate change and that this can be stopped…

Jamie Ashcroft in Proactive Investor explains why declining North Sea gas and a weaker pound make a compelling case for pushing on with UK shale gas developments without further delays.
H/T GWPF

The pending exit from the European Union strengthens the argument for the development of Britain’s currently untapped shale gas resources.

Britain’s energy security should be a concern whether it remains in the EU or not, though the vote to leave makes this an increasingly acute issue. Quite simply Britain doesn’t produce enough gas of its own.

The UK Guardian newspaper is already wringing its hands over the effect of the Brexit vote on its hopes of seeing UK lands and shores smothered with wind turbines.

But Amber Rudd said that the UK remained committed to action on global warming and Whitehall sources have told the Guardian that on Thursday she will approve a world-leading carbon target for 2032.

kites

Wind is an occasional ally in all sorts of recreational pursuits: sailing, kite surfing, puffing on a ready-to-burst dandelion and watching their parasol seeds drift skywards, and the childish delight of sending kites aloft. But it’s taken a special breed of Muppet to turn a source of sporadic fun into a ridiculously expensive, sometime source of electricity.

In our recent post on the comparative debacles of South Australia and the UK we picked up on the line dropped by Britain’s head wind spinner, Hugh McNeal (RenewableUK) who – now that the subsidy trough has been emptied – says there is no chance of any more of these things blighting Blighty as: ‘The wind speeds don’t allow for it.’

After that (stating the bleeding obvious) admission, the few among Britain’s journos that get it had a field day.

After years of being fed a myth about the wind ‘powering’ Britain for…

Booker follows up my story about last week’s interview with Renewable UK’s Chief Exec, Hugh McNeal, which claimed that onshore wind is now the cheapest form of generation:

The interview in last week’s Sunday Telegraph with Hugh McNeal, the new head of RenewableUK, was remarkable in more ways than one. Certainly readers may have been surprised to know how easily he could switch from being a senior official at the Department of Energy and Climate Change (DECC) to running our leading lobby group for wind farms. But even more significant was the way he unwittingly exposed what appears to me to be a massive deceit now at the heart of our national energy policy.

Like DECC, he has bought into the trick of pretending that renewables are now “the cheapest form of new [electricity] generation in Britain”. On the face of it this claim seems…

A major UK trade union echoes what blog critics and others have been saying about the obvious weaknesses of unreliable wind power. Is anyone in political power listening?

There were over 1½ months of low wind days since June 2015 when wind was supplying 10% or less of the installed and connected wind capacity to the grid.

When your electricity supply has “Gone with the Wind” the response of the renewable energy suppliers that “frankly my dear we don’t give a damn” is just not acceptable says GMB.
