It’s essentially an artificial blowhole according to the company CEO. They say the device uses resonance to make the most energy out of the water that washes into it, by operating at the natural frequency of the waves, and claim it’s ‘120% more efficient than a conventional device’.

Wave Swell Energy plans to install a commercial scale wave energy plant in the Bass Strait, off King Island in Tasmania, reports Tidal Energy Today.

Wave Swell’s series of one-megawatt generators will cost up to $7 million to build, and at peak times will provide up to half the power for King Island’s 1,600 residents, according to the Australian Maritime College (AMC).

The Australian-based wave energy developer said it expects the cost of wave power to be less than 10 cents per kilowatt hour when built at scale.

Is solar power in terminal decline in Europe, as subsidies and public enthusiasm dwindle?

Germany’s SolarWorld, once Europe’s biggest solar power equipment group, said on Wednesday it would file for insolvency, overwhelmed by Chinese rivals who had long been a thorn in the side of founder and CEO Frank Asbeck, once known as “the Sun King”.

SolarWorld was one of the few German solar power companies to survive a major crisis at the turn of the decade, caused by a glut in production of panels that led prices to fall and peers to collapse, including Q-Cells, Solon and Conergy.

Bret Stephens at The New York Times delves into the erroneous ‘climate-friendly’ image of biofuels, and questions the claimed success of renewables in general. Not new criticisms, but new for the NYT at least.

A few extracts from the piece:
“Converting biomass feedstocks to biofuels is an environmentally friendly process. So is using biofuels for transportation. When we use bioethanol instead of gasoline, we help reduce atmospheric CO2.”

These confident assurances come from “Biofuels: A Solution for Climate Change,” a paper published in 1999 by the Clinton administration’s Department of Energy. Feels a little dated in its scientific assumptions, doesn’t it?

The author notes that ‘the rigs are getting roughly twice as productive every three years. No other energy technology is improving that quickly.’

Wind and solar are now experiencing a declining rate of improvement as those technologies start to approach their limits in terms of what physics permits. Shale technology is a long way from its physics limits. In fact, the shale industry is at the beginning of what I’ve earlier termed Shale 2.0.

The Promethean task of supplying energy to the U.S. economy and the rest of the world involves scales that are truly difficult to visualize. Many options appear to make sense until you crunch the numbers. That’s why Bill Gates said that people need to bring “math skills to the problem.”

Consider petroleum alone, which accounts for about one-third of global energy use.

Enthusiasm fading for renewables targets?


This could put a bit of sanity back into UK electricity generation policy, if it happens.

Britain is preparing to scrap EU green energy targets which will add more than £100 to the average energy bill as part of a bonfire of red tape after Brexit, says the GWPF.
 
Government sources told The Daily Telegraph that the target, under the EU Renewable Energy Directive, is likely to be scrapped after Brexit.

The UK is currently committed to getting 15 per cent of all energy from renewable sources such as wind and solar by 2020. Ministers have long been critical of the targets because they exclude nuclear power, carbon capture or gains from energy efficiency.

The UK is currently on course to miss the target and incur millions of pounds in fines from the European Union.

Renewables’ deep-sea mining conundrum

Deep sea mining for rare earth minerals [image credit: BBC News]


To what extent do ‘renewables’ depend on finding sources of non-renewables? Mining is involved – the raw materials have to be found and extracted from the earth.

British scientists exploring an underwater mountain in the Atlantic Ocean have discovered a treasure trove of rare minerals, reports BBC News.

Their investigation of a seamount more than 500km (300 miles) from the Canary Islands has revealed a crust of “astonishingly rich” rock. Samples brought back to the surface contain the scarce substance tellurium in concentrations 50,000 times higher than in deposits on land.

Tellurium is used in a type of advanced solar panel, so the discovery raises a difficult question about whether the push for renewable energy may encourage mining of the seabed. The rocks also contain what are called rare earth elements that are used in wind turbines and electronics.

What could possibly go wrong? Like all pumped storage, every ‘refill’ uses more electricity for the pumping than is generated by its water release. The UK is also looking to develop similar schemes. The motivation is the intermittency of renewables.

The German state of North-Rhine Westphalia is set to turn its Prosper-Haniel hard coal mine in Bottrop into a 200 MW pumped-storage hydroelectric plant reports PEI.

The facility will act like a battery and will have enough capacity to power more than 400,000 homes, according to state governor Hannelore Kraft.

Other mines may also be converted after Prosper-Haniel because the state needs more industrial-scale storage as it seeks to double the share of renewables in its power mix to 30 per cent by 2025, she said. North-Rhine Westphalia generates a third of Germany’s power.

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.”

Why Renewables Are Doomed and Fossil Fuels Are the Future

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…

‘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.

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.

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.

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.

Which way next?

Which way next?


Those trying to make a business case for renewable energy may want to look away now. The assumption that vast numbers of solar panels and wind turbines are good for the environment is questionable.

Poverty, unemployment and zero economic growth are the likely outcome for countries which choose renewable energy sources over fossil fuels, according to a study.

Energy from fossil fuels appears to ignite economies into greater and more sustained growth, whereas energy from wind and solar power not only fails to enhance or promote economic growth, it actually causes economies to flat-line, as Phys.org reports.

The results, from an in-depth study of more than 100 countries over 40 years, pose a serious ethical dilemma, according to the lead author, economist Dr Nikolaos Antonakakis, Visiting Fellow at the University of Portsmouth Business School and Associate Professor at Webster Vienna University.

Dr Antonakakis said: “Put simply, the more energy a country consumes, the more it pollutes the environment, the more its economy grows. And the more the economy grows, the more energy consumption it needs, and so on.

“This poses big questions. Should we choose high economic growth, which brings lower unemployment and wealth for many, but which is unsustainable for the environment? Or should we choose low or zero economic growth, which includes high unemployment and a greater degree of poverty, and save our environment?”

Dr Antonakakis and co-authors, Dr Ioannis Chatziantoniou, at the University of Portsmouth, and Dr George Filis, at Bournemouth University, set out to study whether environmentally friendly forms of energy consumption were more likely to enhance economic growth.

In the light of recent policies designed to promote the use of green energy, including tax credits for the production of renewable energy and reimbursements for the installation of renewable energy systems, the authors predicted that environmentally friendly forms of energy consumption would enhance economic growth. Dr Antonakakis said: “It turned out not to be the case.”

They argue that societies now need to rethink their approach toward environmental sustainability, and strongly question the efficacy of the recent trend in many countries to promote renewable energy resources as a reliable alternative for helping achieve and maintain good economic growth.

‘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.

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.

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.
