The project is described as ‘vital’, which may raise questions about the present state of these two national grid systems. The idea that it will help support increased electric car use – that’s one of its claims – is a bit weak as so few people want them.

A major new project to install an interconnector linking the electricity markets of Britain and France via the Channel Tunnel has just put down its foundations, reports PEI.

The foundation stone of the Folkestone Converter Station was laid on Thursday by Jesse Norman, UK Minister for Industry and Energy. The ElecLink 1 GW Direct Current link is expected to cost around £580m.

The project will generate approximately 300 new jobs during the construction phase together with ongoing jobs needed for the operations and maintenance throughout the life of the project.

For some reason (‘de-carbonisation’) the UK government’s actions on electricity supply are usually opposite to its stated policy of ‘secure, affordable’ energy. Expensive and often unreliable power sources are given priority most of the time, apparently in pursuit of climate illusions.

Interventions in the energy market by successive governments have pushed up prices, but not secured supplies, peers found. A House of Lords committee said the interventions have led to an opaque, complicated and uncompetitive market, reports BBC News.

The peers blame “poorly designed government interventions in pursuit of decarbonisation” that they say have put pressure on energy supply and bills. The government said its priority was ensuring secure, affordable energy.

abracadabra-515x396The biomass problem, or fallacy, is well-known and media like The Times are finally catching up.

Britain is wasting hundreds of millions of pounds subsidising power stations to burn American wood pellets that do more harm to the climate than the coal they replaced, a study has found.

Chopping down trees and transporting wood across the Atlantic Ocean to feed power stations produces more greenhouse gases than much cheaper coal, according to the report.

It blames the rush to meet EU renewable energy targets, which resulted in ministers making the false assumption that burning trees was carbon-neutral.

South Australia has found out the hard way that relying too much on wind turbines is bad news for everyone, including the politicians who ordered it.

STOP THESE THINGS

jay weatherill Jay Weatherill’s political future all but blacked-out.

While the power pricing and supply calamity that is South Australia is down to the subsidies awarded to wind power under the Federal government’s Large-Scale RET, the state Labor government has done plenty to create the unfolding disaster and nothing to mitigate it.

It’s vapid Premier, Jay Weatherill must know that, as a wind power champion, he’s yesterday’s ‘hero’ and, as a so-called political leader, today’s fool.

It would be wrong to give Mike Rann and Jay Weatherill all the credit for turning South Australia into wackadoodle windmill world. We should recognise the contribution of those who egged the premiers on, like Al Gore, auteur of An Inconvenient Truth. When it came to showing leadership on renewable energy, said Gore, South Australia was “one of best examples…

H/T GWPF

Germany’s excess power spills over the border into Polish and Czech territory and threatens their electrical grids with collapse, companies and governments there say.

A battle is raging in Central Europe over the balance of power—the electrical kind. Poland and the Czech Republic see Germany as an aggressor, overproducing electricity and dumping it across the border. Germany sees itself as a green-energy pioneer under unfair attacks from less innovative neighbors.

As part of Chancellor Angela Merkel’s Energiewende, or energy revolution, Germany will shut its nuclear power plants by 2022 and replace them with its rapidly expanding wind and solar power. But the volatile renewables don’t always perform, and the Germans are also relying on coal- and gas-powered plants to keep the lights on.

One claim by the developer is that ‘its devices could increase the revenue of a wind farm by 25 per cent, through increased output and exploiting higher wholesale prices when the wind isn’t blowing’. It has to be said that battery and storage innovations have a poor record of turning into commercial success, but as ever time will tell.

An Adelaide company has developed a silicon storage device that it claims costs a tenth as much as a lithium ion battery to store the same energy and is eyeing a $10 million public float, reports Sott.net.

1414 Degrees had its origins in patented CSIRO research and has built a prototype molten silicon storage device which it is testing at its Tonsley Innovation Precinct site south of Adelaide.

Chairman Kevin Moriarty says 1414 Degrees’ process can store 500 kilowatt hours of energy in a 70-centimetre cube of molten silicon – about 36 times as much energy as Tesla’s 14KWh Powerwall 2 lithium ion home storage battery in about the same space.

The ideologically-driven dash for renewable energy in Germany is heading towards a natural obstacle hiding in its winter weather. Will ‘traditional energy’ always be there to provide security of supply when needed?

Germany has a reputation for being a renewable energy leader – but some believe that the nation’s long, still and dim winters threaten such green aspirations, reports DW.COM.

The “dark doldrums” conjures images of the deep Middle Ages, when the only light to be had flickered from a tallow candle. In fact, it is the loose translation for the German word Dunkelflaute, which describes this time of year, when neither sun nor wind are to be found in great abundance.

And this is the very scenario some are suggesting could plunge the nation into, if not quite a re-enactment of its medieval past, then energy uncertainty. An article published recently in the German daily “Die Welt” warned that the Dunkelflaute could be pushing Germany’s power supply to its limits.

Viewing and filming ‘exotic’ electrical events from space sounds like interesting work if you can get it.

For years, scientists have been piecing together evidence of peculiar phenomena known as red sprites, blue jets, pixies and elves – exotic types of electrical discharges that emanate from thunderstorms.

Just one week after his arrival on the International Space Station, Danish astronaut Andreas Mogensen captured the best evidence that blue jets exist, reports Sott.net.

Mogensen’s 160-second video documented 245 blue flashes as the space station flew 250 miles above the Bay of Bengal.

Now the findings have been published in Geophysical Research Letters. “According to the researchers, this is the first time they’ve ever seen this blue lightning shoot up like that,” Mogensen said.

turnbull-frydenberg Yes, boy wonder, it’s a place called ‘Queensland’.

***

In 2016 no two words struck more fear into the hearts of the city-bound, political elite than ‘Trump’ and ‘Brexit’.

In both instances, ignorance amongst the media and political class meant that – for them – what were predictable, if not inevitable, results came as visceral, gut-wrenching, bewildering shocks.

If there is a single issue that has the potential to destroy political incumbents, it has to be energy.

South Australia has proved, without doubt, that skyrocketing power prices and unreliable supply are part and parcel of attempting to run economies on sunshine and breezes. Dutifully ignoring the effect of rolling blackouts and punishing power bills on the businesses and people who grow, build and create things (other than whipping up fair-trade, skinny-soy lattes and smashed avocado on toast at hipster cafés) is a recipe for political disaster.

Windfarm objection in Galloway

Windfarm objection in Galloway


Galloway has some great landscapes and doesn’t need to be disfigured any further by such intrusive monstrosities.

A Scottish government reporter has refused planning permission for a 12-turbine wind farm in Galloway, reports BBC News. He ruled the Shennanton project north of Kirkcowan would have a “significant adverse impact” on the landscape.

Brookfield Renewable had appealed over Dumfries and Galloway Council’s failure to determine its application. The reporter said the significant local support and boost for renewable energy targets did not outweigh the harm to the character of the area.

Roger Harrabin, who is apparently now an energy analyst as well as an environmental one, writes:

The UK has enough energy capacity to meet demand – even on the coldest days when demand is highest, says Steve Holliday, the man who ran National Grid for a decade.

He said news stories raising fears about blackouts should stop.

His optimism is based on the government’s latest auction of capacity for power generation, which starts later today.

‘The donkey goes on to the ice until it breaks’ – German proverb [image credit: evwind.es]


Grasping the nettle of reporting the views of leading German climate sceptic Professor Fritz Vahrenholt, PEI magazine airs several awkward issues arising from Germany’s ambitious – he says reckless – energy policies.

At a mid-January meeting in parliament buildings in London, Professor Fritz Vahrenholt provided a very detailed monologue on the motivations behind Germany’s energy transition, and why he feels it’s misguided and potentially disastrous, writes Diarmid Williams.

Had the lecture been delivered by somebody from the coal power sector, they might have been written off as a ‘climate denier’, but given Vahrenholt’s background and pedigree as a backer of renewable energy, he is not so easily dismissed and his position must cause some unease for those so adamant that climate change is man-made.

Tidal lagoons are uneconomic

That’s the view of the GWPF, as explained below. Whether the UK government will be put off by the huge cost of the subsidies remains to be seen.

Mr Hendry’s report implicitly recommending that the UK government support the £1.3 billion Swansea Tidal Lagoon project presumably moves the scheme one step closer to realisation.

However, the headline facts show that there is no justification for compelling UK consumers to de-risk the scheme for its projectors.

The principal and overwhelming disadvantage of most renewable electricity technologies is that they are of low energy productivity in themselves and reduce the productivity of the electricity system of which they are a part.

Ouch – embarrassing for the builders and a hefty bill for somebody. No reports of any injuries.

A wind turbine has collapsed in the south-west of Scotland, BBC Scotland understands.

The incident happened at Kilgallioch wind farm, which straddles the border between Dumfries and Galloway and South Ayrshire, early last Friday.

An investigation has been launched by developer Scottish Power Renewables and turbine manufacturer Gamesa.

Can politicians put sanity ahead of ideology for Australian electricity generation following recent blackout fiascos?

The Australian Prime Minister Malcolm Turnbull has reinforced his belief in the importance of coal as a pragmatic part of the global energy mix, reports PEI. The Australian online reports Turnbull as saying he had the same opinion while leader of the opposition in 2009.

“We are the biggest coal exporter in the world. If anybody — if any country — has a vested interest in demonstrating that clean coal and cleaner coal with new technologies can make a big contribution to our energy mix — and, at the same time, reduce our emissions in net terms — it’s us.”

“Our approach, and my approach, to energy is absolutely pragmatic and practical. This is not a matter for ideology.” Mr Turnbull said both renewables and fossil fuels would have a role to play in energy production in the future.

Electric vehicles still in the foothills

As the author suggests, the wishful thinking of policy makers in the world’s better-off countries shows little sign of turning into success ‘on the ground’ when it comes to electric vehicles. Public concerns about cost, range, battery life, recharging and so on are not going away.

An article in Power Engineering International magazine in 2013 by Penny Hitchin identified progress in the development of electric vehicles, as well as the barriers to progress, writes PEI’s Diarmaid Williams.

Four years later, despite a relative surge in uptake of these vehicles, much of the same barriers remain. It’s anticipated that the evolution of the electric vehicle will transform the nature of electric power, but this evolution is unfolding at a slower rate than perhaps anticipated, or desired given the political expediency to decarbonise.

When Hitchin penned her piece, Charging ahead: EVs and the grid, there were 130,000 electric vehicles in the US. In December 2016 that figure was 542,000, according to Recode website, so there is an incremental rise, even if it’s not as rapid as hoped. The same problems are besetting countries around the world in moving away from fossil fuels and capitalising on the extraordinary progress of renewable power.

It’s a similar situation for cars.

Bloggers and others have been stating the obvious for years: relying on unreliable electricity generation from renewables like wind and solar energy can’t possibly work. For the hard of thinking, the clue is in the word ‘unreliable’. The penny has to drop with political leaders, or at least their voters, sooner or later – surely?

The End of the Energiewende? – by German economist Heiner Flassbeck

Stable high-pressure winter weather has resulted in a confrontation. An Energiewende that relies mainly on wind and solar energy will not work in the long run. One cannot forgo nuclear power, eliminate fossil fuels, and tell people that electricity supplies will remain secure all the same.

We have attempted unsuccessfully to find Energiewende advocates willing to explain that inconsistency. Their silence is not easy to fathom. But maybe the events themselves have made the outcome inevitable.

With nuclear power no longer available, a capacity of at least 50 gigawatts is required by other means, despite an enormously expanded network of wind turbines and solar systems.

This winter could go down in history as the event that proved the German energy transition to be unsubstantiated and incapable of becoming a success story.

While STT was taking a well earned summer break, South Australians found themselves, yet again, groping around in the dark.

In the lead up to Christmas, South Australians living on its West Coast in places like Ceduna were left powerless for close to 3 days, said to be the result of storm damage to transmission lines and equipment.

Immediately after Christmas, huge swathes of South Australia found themselves without power for days on end.  We’ll start with a roundup from the ABC.

Solar towers in California [image credit: ucsusa.org]


It may sound good but California’s Mojave project showed projects like this are not always exactly what they may seem. Scorched birds brought bad publicity for example.

The world’s tallest solar tower is currently being constructed in Israel’s Negev desert, the latest example of the Jewish state’s newfound emphasis on renewable energy, The Tower reports. The tower, which will be 250 meters (820 feet) tall, is encircled by around 50,000 mirrors, called heliostats.

Unlike the more common photovoltaic solar panels, which convert sunlight directly into power, the heliostats reflect the sunlight into the tower to heat a boiler, which will produce the steam to spin a turbine to generate electricity. With a taller tower, more mirrors can be placed in a smaller area to reflect the necessary amount of sunlight to run the turbine. 

There are only about a dozen solar tower fields around the world, including one in California with three towers, each of which is 140 meters (460 feet) tall, surrounded by 170,000 heliostats.

At the end of the day this still looks like trying to make a silk purse out of a sow’s ear in terms of efficiency.

The amount of energy generated by renewables fluctuates depending on the natural variability of resources at any given time. The sun isn’t always shining, nor is the wind always blowing, so traditional power plants must be kept running, ready to fill the energy gap at a moment’s notice.

Because the grid has no storage, and unlike coal or nuclear, there is no control over the fluctuating production of renewable energy, the energy they produce has to be consumed straight away, or risk collapsing the electrical grid.
