Reblogged from Euan’s excellent site, Energy Matters.

“The Scottish Government’s targets are for renewable sources to generate the equivalent of 100 per cent of Scotland’s gross annual electricity consumption by 2020.” What will the consequences be for the Scottish People?

This post models Scottish electricity production and consumption in 2020 and compares this with 2012. It is assumed that Scotland’s two nuclear power stations remain operational in 2020. The reader is asked to always recall that the numbers are based on models and the conclusions therefore carry uncertainty. The consequences of this energy policy may be:

  • A large electricity surplus of about 15 TWh may be produced in 2020, worth about £2.5 billion at 17p / KWh.
  • There are currently many ideas but no certainty about where this surplus might go. It seems possible that a large part may simply be wasted.
  • Assuming that marine renewables remain negligible and hydro output remains unchanged in 2020 then the bulk of the expansion in renewables to meet the target will most likely be met by wind that will require a 5 fold increase relative to 2012.
  • In an independent Scotland the subsidy payments currently made to renewables companies by 63 million UK citizens would fall pro rata on the shoulders of 5.3 million Scottish citizens. This, combined with the 5 fold increase in wind capacity may mean a 25 fold increase in the level of renewable subsidy born by Scottish electricity consumers. Electricity bills may double.

In summary, the Scottish Government energy plan may result in a large electricity surplus that at present has nowhere to go, the number of wind turbines may increase 5 fold and electricity bills may double.

The question is prompted from reading this report on the BBC website:
‘World’s Fair: Isaac Asimov’s predictions 50 years on’

Tesla’s concept of free wireless electricity never made it to market, but maybe one day…

An obvious one might be the fusion reactor, as Asimov foresaw: “An experimental fusion-power plant or two will already exist.”

Chances must be good (?) if schoolboys can already build their own:

More likely is the commercial development of methane hydrates as an abundant energy source, if or when shale gas has run its course or is politically a no-no:

Or we could all be spurning fuel technology, piling on the thermal clothes and going around on bicycles, hoping the sun shines and the wind blows ;-)

From the too not-funny to be as funny as it should be dept:

Thunder-Bay-OPG-Generating-StationOntario is now the first jurisdiction in North America to fully eliminate coal as a source of electricity generation. The Thunder Bay Generating Station, Ontario’s last remaining coal-fired facility, has burned its last supply of coal. Operated by Ontario Power Generation, Thunder Bay Generating Station was the oldest coal-fired station in the province. The plant is scheduled to be converted to burn advanced biomass, a renewable fuel source.

The province has replaced coal generation with a mix of emission-free electricity sources like nuclear, waterpower, wind and solar, along with lower-emission electricity sources like natural gas and biomass. The move to bio-mass rather than to natural gas has raised concerns in Thunder Bay. NOMA and Common Voice Northwest, and the City of Thunder Bay have all expressed concerns.

If you thought shutting down the railways for Monday morning commute was a poor show, now we find that two of the reactors at Dungemess have been taken offline due to the rainy and windy weather too. This from the Telegraph:

nuke-powerA nuclear power station automatically shut down its reactors after debris blown by hurricane-strength winds fell onto its power lines and led to a loss of supply.

It could be up to a week before the two units at Dungeness B plant in Kent – one of Britain’s nine nuclear power stations – are up and running again.

But a spokeswoman for EDF Energy, which runs the site, said she hoped energy would be restored much sooner and that the public should “absolutely not” be concerned by the shut-down.

Excerpt from a good article on Scriptonite Daily. Read the whole thing, it has a wide perspective.

C40Stupid, Corrupt, or Both

It was announced this week that the government as agreed a strike price for energy produced by EDF Energy’s planned new nuclear power plants.  The strike price is the price the government guarantees EDF will receive per MegaWatt/Hour of energy produced.  The current market rate is£47.50.  The government has promised EDF £92.80.  Yes, you read that correctly – the UK government has guaranteed EDF Energy twice the market rate.

As with Fracking, the government is using recent energy price hikes by the Big 6 energy firms as a case in favour of New Nuclear – implying or explicitly stating that prices will come down.  However, in agreeing this strike price the government has guaranteed that they will not.  They have fixed the price for energy produced by New Nuclear at twice the market rate.

Another bad deal for the taxpayer and the consumer, brokered by a government that consistently delivers for big business.

NowindFrom the Telegraph:

Owen Paterson, the Environment Secretary, has commissioned a consultancy to investigate whether renewable technologies – including wind turbines – lower house prices in the countryside.

Chris Heaton-Harris, the Conservative MP for Daventry, said:

“Wind farms definitely affect house prices and it is highly likely that this report will come to that conclusion…I would expect there to be billions of pounds of planning blight because of wind turbines close to properties…. It’s almost like elements of DECC are acting like a mafia … now you’ve got DECC trying to stick its dirty great footprints all over another department’s work. While this is unsurprising, it will all unravel in the end and I’m sure the evidence will come out soon that proves a number of these points correct.”

He said that one of his constituents had seen the value of their £700,000 property fall by £250,000 because of approved plans for a wind turbine.

earth cross section

I think there are probably quite a lot of ramifications to this news for climateers to consider which I’m too tired to think of. Over to the talkshop massive:

The core of the Earth is nearly 1,000 degrees hotter than previously thought, making it as fiery as the surface of the sun.

Following new experiments, scientists have established that the core temperature is 6,000 C, much higher than the previous estimate of 5,000.

Using X-rays to probe into the behaviour of iron crystals, putting samples of iron under extreme pressure, researchers were able to examine how iron crystals melt and form.

The new tests, using one of the world’s most intense sources of X-rays located at the European Synchrotron Radiation Facility, the research team were able to re-create the same pressure at the core.

This article on Spiegel Online is surprising for a German publisher.

Seems to be claiming German is in fiscal trouble and is dumping some holy cows.

“Berlin can’t afford many of its renewable energy programs.”

Then goes on “As prices for carbon emissions continue to languish, Berlin is planning to cancel some key subsidy programs aimed at increasing reliance on renewable energies. Germany and other European countries seem uninterested in fixing the problem.” (my bold)

A new  nuclear plant will be built at Hinkley Point in Somerset after Energy Secretary Ed Davey granted planning permission.

The development of Hinkley Point C by French energy company EDF is a boost for the nuclear industry following a series of setbacks in plans to construct a new fleet of reactors in the UK, which ministers say are needed to cut carbon and keep the lights on.

Hat tip to Paul Vaughan [and A C Osborn on comments], who spotted this interesting new article at NASA’s website:

March 8, 2013: Using data from an aging NASA spacecraft, researchers have found signs of an energy source in the solar wind that has caught the attention of fusion researchers. NASA will be able to test the theory later this decade when it sends a new probe into the sun for a closer look.

The discovery was made by a group of astronomers trying to solve a decades-old mystery: What heats and accelerates the solar wind?

nasa-wind

The solar wind is a hot and fast flow of magnetized gas that streams away from the sun’s upper atmosphere.  It is made of hydrogen and helium ions with a sprinkling of heavier elements.  Researchers liken it to the steam from a pot of water boiling on a stove; the sun is literally boiling itself away.

“But,” says Adam Szabo of the NASA Goddard Space Flight Center, “solar wind does something that steam in your kitchen never does.  As steam rises from a pot, it slows and cools.  As solar wind leaves the sun, it accelerates, tripling in speed as it passes through the corona. Furthermore, something inside the solar wind continues to add heat even as it blows into the cold of space.”

Finding that “something” has been a goal of researchers for decades.  In the 1970s and 80s, observations by two German/US Helios spacecraft set the stage for early theories, which usually included some mixture of plasma instabilities, magnetohydrodynamic waves, and turbulent heating.  Narrowing down the possibilities was a challenge. The answer, it turns out, has been hiding in a dataset from one of NASA’s oldest active spacecraft, a solar probe named Wind.

A few years ago massive Greenland gained some autonomy from it’s tiny owning state Denmark, shortly after that prospecting for Uranium was allowed. Now the problems moves on to allowing exploitation of the world’s (maybe) fifth largest reserve of uranium.

But the Danes are petty, declare what they don’t have is not allowed, so there.

Psst… look… want some?

“Government leaning toward allowing uranium mining in Greenland”

Cracks are appearing in the the Coalition UK government over energy policy. Energy minister Lib-Dem Ed Davey is furious over statements made to the Daily Mail by junior minister John Hayes concerning wind farms:

A furious coalition row erupted today after a junior Tory minister declared that the relentless march of onshore wind farms is at an end.

Insisting ‘enough is enough’, energy minister John Hayes said turbines had been ‘peppered around the country’ with little or no regard for local opinion.

He said existing sites and those in the pipeline would be enough to meet green commitments with no need for more.

‘Even if a minority of what’s in the system is built we are going to reach our 2020 target,’ he said. ‘I’m saying enough is enough.’

But at an early-morning showdown with his boss – Lib Dem Energy Secretary Ed Davey – Mr Hayes was told he does not decide government policy.

Last night the Leeds Sceptical Climateers (Ian, Susan and myself) attended a panel discussion given by the Earth Sciences department at Leeds University’s beautiful Clothworkers Centenary Hall.

Topping the bill was Jonathan Porrit, the veteran alternative energy and environmental campaigner. Also speaking were “the two Andy’s”, as Porrit referred to them, Professor Andrew Gouldson, and Professor Andrew Shepherd. Their three topics were:   ‘innovation in a low carbon future’, ‘should climate change really be a priority in an age of austerity?’ and ‘is global sea level rise the threat we imagine it to be?’.

Europe’s Climate Energy Fixation Moves On

Andrew McKillop

Günther Oettinger in a pensive pose contemplates Europe’s energy future.

Writing in the German daily Handelsblatt, July 16, the European Commissioner for energy, Gunther Oettinger claimed it was now urgent and rational for the Union to add “another 20% target” to the three 20-20-20 energy targets for 2020, enshrined in the December 2008 climate-energy package. This would be a goal of 20% of the European Union’s GDP coming from industrial activities, but due to rampant de-industrialisation, the present industrial share is well below 20%, and falling.

The energy targets are a planned 20% hike in energy efficiency, a 20% cut in CO2 emissions (both of these from variable base years with variable ways of measuring the goals), and attaining a 20% share of renewable energy in European power production by 2020 – which can be interpreted as the upstream primary energy needed to produce electricity, or only the downstream final delivered electricity.

Story from Bloomberg: H/T Andrew McKillop

Electricite de France SA, Europe’s biggest power generator, said it’s seeking partners to help finance new nuclear plants in the U.K. after debt swelled.

“We are considering the possibility of opening a little more the capital of these projects by finding a partner,” Senior Executive Vice President of Finance Thomas Piquemal said today on a conference call. “We are considering a better means to finance them and the best way to attract partners.”

EDF is studying building two new reactors at Hinkley Point in southwest England and a further two at its Sizewell site in eastern England. The decision to seek partners follows a 19 percent jump in debt in the first half and comes four months after German utilities EON AG and RWE AG (RWE) scrapped a British project, saying they couldn’t justify the capital expenditure.
