Icebergs in the North Atlantic [image credit:

H/T Paul Vaughan
Whether admittedly stronger than usual winds have led to more iceberg material and/or some of the ‘normal’ icebergs have broken up into smaller ones, is not clear, perhaps not known. A record 953 icebergs were observed in April 1984.

More than 400 icebergs have drifted into the North Atlantic shipping lanes over the past week in an unusually large swarm for this early in the season, forcing vessels to slow to a crawl or take detours of hundreds of kilometres, reports CTV News (via AP).

Experts are attributing it to uncommonly strong counter-clockwise winds that are drawing the icebergs south, and perhaps also global warming, which is accelerating the process by which chunks of the Greenland ice sheet break off and float away.

As of Monday, there were about 450 icebergs near the Grand Banks of Newfoundland, up from 37 a week earlier, according to the U.S. Coast Guard’s International Ice Patrol in New London, Connecticut. Those kinds of numbers are usually not seen until late May or early June. The average for this time of year is about 80.

View from Titan [artist’s impression]


‘The grains that cover Saturn’s [largest] moon act like clingy packing peanuts.’ An obvious question might be: where is Titan’s electrical charge coming from?

Experiments led by researchers at the Georgia Institute of Technology suggest the particles that cover the surface of Saturn’s largest moon, Titan, are “electrically charged.”

When the wind blows hard enough (approximately 15 mph), Titan’s non-silicate granules get kicked up and start to hop in a motion referred to as saltation. As they collide, they become frictionally charged, like a balloon rubbing against your hair, and clump together in a way not observed for sand dune grains on Earth — they become resistant to further motion.

They maintain that charge for days or months at a time and attach to other hydrocarbon substances, much like packing peanuts used in shipping boxes here on Earth. The findings have just been published in the journal Nature Geoscience.

“If you grabbed piles of grains and built a sand castle on Titan, it would perhaps stay together for weeks due to their electrostatic properties,” said Josef Dufek, the Georgia Tech professor who co-led the study. “Any spacecraft that lands in regions of granular material on Titan is going to have a tough time staying clean. Think of putting a cat in a box of packing peanuts.”

The electrification findings may help explain an odd phenomenon. Prevailing winds on Titan blow from east to west across the moon’s surface, but sandy dunes nearly 300 feet tall seem to form in the opposite direction.

The construction agreement is planned to be signed on 23 March 2017, reports The Independent.

A vast artificial island is to be built at Dogger Bank in the North Sea, complete with a harbour, airstrip and homes, to help provide a vast new supply of renewable energy, under plans drawn up by two companies with the blessing of the European Union.

The North Sea Wind Power Hub would act as a hub for offshore wind turbines and a new place to put solar panels, according to the German and Dutch arms of electricity firm TenneT and Danish company Energinet. The firms will sign a deal creating a consortium to develop the plan further in Brussels on 23 March in the presence of European Energy Union Commissioner, Maos Sefcovic.

Torben Glar Nielsen, Energinet’s Danish technical director, said: “Maybe it sounds a bit crazy and science fiction-like, but an island on Dogger Bank could make the wind power of the future a lot cheaper and more effective.”

We’re on the verge of a new energy revolution. Except it’s the exact opposite of the one the “experts” at places like BP, the International Energy Agency and – ahem – the Guardian are predicting.

For years we’ve been assured by politicians, energy industry specialists and green advocates that renewables such as wind and solar are getting more and more cost-competitive while dirty fossil fuels are so discredited and wrong and evil we’ll soon have to leave them in the ground.

Reality is catching up with wind power dreamers in South Australia as the public wake up to the truth – via power failures.

STOP THESE THINGS

alice_in_wonderland17 Fantastic in theory, but reality is another place.

***

It’s been barely 5 months since South Australia experienced a state wide blackout on 28 September, when a typically vigorous spring storm delivered wind speeds in excess of 90km/h, causing the majority of turbines operating at its 18 wind farms to automatically shutdown to avoid self-destruction. The ensuing collapse in wind power output overloaded the interconnectors with Victoria, which tripped automatically; and thereafter South Australia suffered what is now known as a ‘system black’ (see our post here).

With a string of blackouts during December (see our post here) and mass load shedding during a heat wave when, yet again, wind power output plummeted (see our post here), humour among South Australians is now a rare and treasured commodity.

Inversely related to South Australians’ fury at their power pricing and supply calamity, is the battle that the wind…

Some of the blazes were accidental, and as people travel more the areas at risk are increasing.

A new study blames people for triggering five out of every six wildfires in the United States and tripling the length of the wildfire season, reports the Daily Mail Online.

Even as climate change worsens the nation’s fire season – making it longer and easier to burn more acres – researchers say human activities play an even bigger role.

Scientists looking at fire data from 1992 to 2012 found that 84 percent of all U.S. wildfires were started by people, either by accident or on purpose.

‘Wind power on steroids’ or another madcap ‘sustainability’ scheme that never gets off the ground? No mention of storage, and typhoons are far from everyday events.

In what could be the ultimate clean energy, Japan is set to start harnessing the energy of typhoons, with wind turbines that are able to withstand intense storms – and turn them into power, reports the IB Times.

Typhoon turbines, also known as the Magnus Vertical Axis Wind Turbine (VAWT), were first thought up by Atsushi Shimizu, chief executive of Challenergy Inc. After seeing the widespread destruction caused by the Fukushima nuclear disaster, he wanted to find a way to provide a safe and sustainable source of energy.

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.

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.

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.

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.

So where does this obvious nonsense come from?

TYV says: ‘Installed capacity is not the same as production. Why is that so incredibly hard to understand for journalists?’

Because such realities would ruin their story perhaps? Either that or they are not up to their jobs. Maybe they aren’t up to the job anyway if they are having to resort to distortion of facts.

Trust, yet verify

The journalists of our beloved Flemish media seem to go ballistic lately. Yesterday there was the item in the VTM news about the current “drought” that was “direct result of climate change”. Today the VRT news felt it had to compete with that and went full stupid in an article with the sensational title:

Flemish windmills have almost the same capacity as a nuclear reactor

vrt news 20161228 windmil

Apparently the onshore windmills in Flandres have a total capacity of 920 MW, which is only slightly below the capacity of (some of) our nuclear turbines (at somewhat above 1,000 MW).

Hurraaaah!!!

I am afraid that I have to spoil that party…

If this research is correct, large windfarms could be losing a huge part of their potential output due to inadequate spacing, as Phys.org reports. Quote: “We found these dramatic effects at turbine spacings commonly used in present-day wind farms on land.”

Wind energy has been remarkably successful in providing an increasing share of cheap renewable energy. But can this trend continue to supply more and more renewable energy for decades to come?

A new study published by scientists from the Max Planck Institute for Biogeochemistry in Jena, Germany, lowers the expectations of wind energy when used at large scales.

South Australia’s ludicrous attempt to run on sunshine and breezes hit a ‘black spot’ on 28 September this year, when – yet another – totally unpredictable collapse in wind power output plunged the entire state into Stone Age darkness: ‘GUILTY’: South Australia’s Statewide Blackout Caused by Deliberate Wind Farm Shutdown

Many parts of the State remained without power for days and thousands of businesses together suffered multi-$million losses. The biggest of those losses were suffered by Nyrstar’s lead and zinc smelter at Port Pirie, BHP Billiton’s gold, copper and uranium mine at Olympic Dam, Oz Mineral’s Prominent Hill copper and goldmine and Arrium’s steel works at Whyalla: collectively, the losses suffered by SA’s miners and mineral processors are in the tens of $millions.

With litigators breathing down their necks, nervous wind power outfits are running confused and desperate interference over the (now, well-known) cause.

David Crowe in The Australian reports on the row about renewable energy policies in the wake of the storm that crashed South Australia’s entire state power grid. Phrases like ‘reality check’ and ‘sow the wind, reap the whirlwind’ spring to mind.
H/T GWPF

The Australian government will confront the states over the ­danger of statewide blackouts at an urgent meeting tomorrow to respond to the outage across South Australia last week, amid a furious political fight over ­whether wind farms helped cause the failure.

The states are being warned that their growing use of renewable energy will make their power networks more vulnerable to outages, leaving Australians at risk of blackouts from any repeat of last week’s ferocious storm.

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.

Another climate mystery – this time the QBO – for scientists to get their teeth into, as the Mail Online reports.

For more than 60 years, atmospheric scientists have observed the consistent behaviour of a wind pattern known as the ‘quasi-biennial oscillation’ – a phenomenon that repeats every 28 months. But in late 2015, the long-reliable pattern suddenly changed. 

The winds have since returned to their normal course, and while no immediate effects were detected, astronomers are working to understand if this was just a one-time ‘black swan’ event, or a ‘canary in the coal mine’ signalling unseen conditions.

If Oregon is modelling its electricity supply policy on South Australia, it should know what to expect, as Hot Air reports.

If you live in Oregon and rely on certain fancy, high tech features of the industrial revolution such as having lights in your home and refrigerated food, you might want to start stocking up on candles and non-perishable goods.

The green energy warriors have pretty much taken over the state legislature in the Beaver State for more than the past decade and they’ve managed to pass all sorts of interesting laws. One of them was a rule which says that all coal fired power will be eliminated by 2020… a deadline which is pretty much right around the corner.
