Ground-breaking test bed for new offshore Wind Technologies

Ground-breaking test bed for new offshore Wind Technologies

Clean Technica in an article dated April 10th, 2018 by reported that the world’s most powerful wind turbine, the first of two 8.8 megawatt (MW) turbines, has been successfully installed at Vattenfall’s European Offshore Wind Deployment Centre off the coast of North East Scotland, which is set to be a ground-breaking test bed for new offshore wind technologies.

Vattenfall is a leading European energy company, that for more than 100 years has electrified industries, supplied energy to people’s homes and modernised our way of living through innovation and cooperation.

World’s Most Powerful Wind Turbine Installed At Vattenfall’s European Offshore Wind Deployment Centre


 

The European Offshore Wind Deployment Centre (EOWDC) in Aberdeen Bay, Scotland, was conceived as a 92.4 MW, 11 turbine offshore wind test and demonstration facility. The project was initially caught up in a protracted legal battle with none other than then-real estate magnate Donald Trump — who promptly lost all legal challenges to prevent the construction of an offshore wind farm he considered would be an eyesore for members of his nearby Trump International Golf Club.

Since then, however, progress has proceeded rapidly, and the hopes of many have come to fruition with the creation of a next-generation testbed for new offshore wind technologies, such as the recently demonstrated suction bucket jacket foundations — which I maintain are cooler than they sound. Supported by the massive 25,000 tonne Asian Hercules III floating crane (seen below), the foundations for the EOWDC are being installed using a new method of securing the massive towers to the seafloor that is faster, more environmentally friendly and quiet, and much easier to uninstall if and when necessary.

Now, the next phase of construction has resulted in the installation of one of two wind turbines which have been specifically enhanced to increase their output by modifying their internal power modes. Specifically, the two turbines have been increased from 8.4 MW to 8.8 MW, which in turn increases EOWDC’s output to 93.2 MW, and as such it will generate 70% of Aberdeen’s domestic electricity demand while displacing 134,128 tonnes of CO2 annually. This is the first time an 8.8 MW wind turbine has been installed for commercial application.

It might not sound a lot — an increase of 0.4 MW — but the EOWDC is intended to serve as a demonstration facility, first and foremost, and testing the application of these incremental increases to wind turbine output could yield significant benefits. Two wind turbines modified such may only increase overall output by 0.8 MW, but a wind farm made up of 100 of these turbines would benefit from a 40 MW increase, simply by modifying existing turbines.

“The turbines for the EOWDC, Scotland’s largest offshore wind test and demonstration facility, help secure Vattenfall’s vision to be fossil fuel free within one generation,” said Gunnar Groebler, Vattenfall’s Head of Business Area Wind. “The EOWDC, through its innovative approach to cost reduction and pioneering technologies, leads the industry drive towards generating clean and competitive wind energy power – one that will reinforce Scotland’s global energy status.”

The V164-8.4 MW and V164-8.8 MW wind turbines were manufactured and modified by MHI Vestas, and have an enormous tip height of 191 meters, with 80 meter blades.

“The first turbine installation is a significant achievement and credit to the diligence and engineering know-how of the project team and contractors,” added EOWDC project director at Vattenfall, Adam Ezzamel. “For it to be one of the 8.8MW models makes it an even more momentous moment because it further endorses the EOWDC as a world-class hub of offshore wind innovation.

“We are very excited by the cutting-edge technology deployed on all the turbines and it is remarkable that just one rotation of the blades can power the average UK home for a day.”

The news was unsurprisingly met with appreciation from UK environmental groups as well.

“Scotland is home to approximately 25% of Europe’s offshore wind resource and projects like Vattenfall’s European Offshore Wind Deployment Centre in Aberdeen promise to harness this potential on a massive scale,” said Stephanie Conesa, Policy Manager at Scottish Renewables. “This ground-breaking facility leads Aberdeen’s ongoing transition from fossil fuels to renewables, and reinforces Scotland’s global energy status.

“As the windiest country in Europe with some of the deepest waters, we should be proud of Scotland’s burgeoning offshore wind industry,” Conesa added. “With many more promising offshore wind sites on our doorstep, we hope to see similar facilities deployed in Scottish waters in future so we can fully utilise our country’s natural resources.”

“The installation of the first of these powerful turbines at Aberdeen Bay is another milestone in Scotland’s renewables story,” added Gina Hanrahan, Acting Head of Policy at WWF Scotland. “Offshore wind, which has halved in cost in recent years, is critical in the fight against climate change, helping to reduce emissions, keep the lights on and create thousands of jobs across the Scotland and the UK.

“Developments like this have an important role to play in securing the Scottish Government’s target to meet half of all Scotland’s energy demand from renewables by 2030.”

International Students in Britain and the English language requirements

International Students in Britain and the English language requirements

In the United Kingdom, all universities state their English language requirements in writing, speaking, listening and reading and have them checked through various tests with the minimum grade overall, and usually the minimum grades required specifically tailored for each course.  International Students in Britain and the English language requirements are a problematic that is recurrent at every start of a new academic year.

The reasons are various.

The affluence of worldwide candidates coupled with the ever-increasing university costs have over the years been the influencing factors of this seeking higher mastery levels of the English language from each and every one.

We republish this article of Bobby Pathak, Heriot-Watt University not only because of the great majority of the MENA’s youth obvious interest in universities of the United Kingdom but to also try and lend a hand to all. .

Do international students in Britain need better English skills?

File 20170905 13709 bai7ol

The start of the academic year is fast approaching, with new students from across the UK looking forward to starting university with a mix of trepidation and excitement.

The UK is also a popular place for international students to study, given that it has some of the best universities in the world. This means that many UK students studying at a British university will be joined in their lectures by students from around the world.

The latest UK Council for International Student Affairs report shows that Chinese students studying at UK universities have far exceeded any other nationality since 2013. The same report also reveals that China is the only country showing significant increases compared with other non-EU countries where recruitment is virtually stagnant.

For many of these students from China, this may be the first time they are educated in only English. And there is the expectation that these students will be able to fully understand and keep up with other students.

Language ability

Having adequate English language skills is important to international students, as there’s no point in them turning up on their first day only to realise they don’t understand the curriculum. In the same way, this proficiency is also important to native English speakers – given that many courses require an element of group work and seminar discussions. Universities don’t want to accept students who will ultimately fail their course either.

International students are offered a place at UK universities on the condition that they have a certain level of English language proficiency. This is checked through a UK Home Office approved test known as the Secured English Language Test.

International students can sometimes struggle with the language.

In theory, students sit the test, pass and then look forward to starting their new life in a new country. But things get problematic when students do not achieve the required score. In this case, universities may then offer an additional pre-sessional programme of English language study at an extra cost to the student. If completed successfully, this allows these students onto their chosen course.

So far, so good. But the the problem here is that many students do not actually take the Secured English Language Test at the end of their pre-sessional programme. This means that it’s never categorically known if, by the end of the summer course, a student’s language proficiency is at the level originally required by the university.

Testing times

That said, it’s not in the interest of universities to set a student up for failure. But surely if the entry requirement of a university course is a certain grade in the Home Office exam, then the same exam should be given at the end of these programmes. This would help to maintain a level playing field for all students on the course.

As someone who works on these pre-sessional programmes as an assistant professor, I believe there is clearly a value in teaching English for academic purposes. These sessions are also a time when nonnative learners can get a sense of the UK’s academic culture along with the conventions they will be expected to follow – something some UK students would also benefit from, too.

International students need to be made to feel welcome.

But of course, the point of the programmes is about getting students up to a certain standard of English. Perhaps then the answer is for the Home Office approved tests to be changed to better reflect what is being covered in university pre-sessional programmes.

What this all boils down to is that universities must make sure they are doing enough to support international students. And this support is particularly important given the outcome of the EU referendum and the UK’s apparent fixation with immigration. In this way, the numbers speak for themselves – international students wanting to come and study in the UK is no longer something universities can simply take for granted.

7 Must Have Student-Collaboration Apps

7 Must Have Student-Collaboration Apps

An article of The Tech Edvocate written by Matthew Lynch and published on Aug 09, 2017 gives an idea on how education has evolved into increased depth mainly through more reliance on digital computation. This calls on diverse and bespoke application software. In the author’s opinion, these number 7 must have student-collaboration Apps that are the most used ones for the specific capabilities of each.

Would this article apply to the MENA region as well ?

7 Must Have Student-Collaboration Apps, Tools, and Resources

Collaboration in the classroom helps students process and deepen knowledge. Students also develop important real-world skills like problem-solving, communication, teamwork, and leadership.

When you choose the right tools, incorporating technology can further enhance student collaboration and learning outcomes. Here are seven of the best student-collaboration apps, tools, and resources for you to try this school year.

  1. Google Apps for Education

With Google Docs, students can share and collaborate on documents. Color-coded icons show who is typing or editing what in real time.

Google Hangouts facilitates small group discussions, and it’s compatible with any device. Students can also create presentations together with Google Slides or collaboratively build diagrams using Google Drawings.

  1. Debate Graph

Students can participate in group debates or build collaborative brainstorms on any complex topic. Subject maps and spider graphs can be saved and presented to the class or scored by the teacher.

  1. TalkBoard

According to Forbes, it’s an “indispensable tool for illustrating collaborative ideas on the fly.” Students can visually express and build on ideas using iPads.

This app can be particularly excellent for language learners, autistic students, and visual learners.

  1. Padlet

Essentially a virtual bulletin board, Padlet is perfect for collaborative discussions. Teachers or students start by posing an open-ended question. Students respond with words, images, audio, or video. All responses appear on the original “wall” in real time, and students can comment on one another’s posts.

  1. Twiddla

Twiddla calls itself a “meeting platform” where students can collaboratively mark-up graphics, photos, webpages, and uploaded documents. Students may opt to brainstorm on a white canvas or create mind maps as well.

  1. TodaysMeet

This very easy-to-use backchannel tool allows teachers to create a chatroom for the class. Students can ask questions, respond to questions, have collaborative discussions, or provide feedback on your lesson. The site also has a polling feature.

  1. Wikispaces Classroom

WikiSpaces Classroom gives you and your students a safe, private network for having discussions, collaboratively editing pages, and completing group projects. There are pre-built templates for a variety of projects, but students can also work from a blank slate.

You can track all student progress in real time and immediately communicate feedback to your students, whether they’re at home or in your classroom.

These apps, tools, and resources can all be quickly and easily implemented to enhance communication and collaboration in your classroom.

General Elections in the United Kingdom and the GCC

General Elections in the United Kingdom and the GCC

This article of Jameel Ahmad, Vice President of Corporate Development and Market Research at FXTM and BA (Hons) degree in Business Studies with Accountancy and Finance from the University of the West of England published on AMEinfo of May 31st, 2017  is pertinently about the General Elections in the United Kingdom and the GCC.  It was the UK Prime Minister who called for these elections for next Thursday, in fact three years earlier than scheduled.
The reasons were to obviously strengthen the hands of the eventual winner who will be deemed to negotiate the Brexit with the European Union.
These elections might however affect all countries, starting of course with those of the EU but also those of the GCC; object of this article of Jameel Ahmad.

Could the upcoming UK election represent a risk to GCC markets?

With the OPEC meeting now in the past, investor attention has shifted towards the United Kingdom and the upcoming General Election scheduled for 8 June. Although the market currently appears calm ahead of the event, this event it does represent a risk for emerging assets and this will include those markets in the UAE and GCC region.

With investors currently positioning in favour of Theresa May being declared victorious next week, there is a risk that investors are heavily under-pricing any other potential outcomes at present. The largest risks to emerging market assets are generally when potential outcomes are heavily underpriced, and recent history from the EU Referendum last June is a kind reminder of what can happen when investors are caught on the wrong side of the trade. If recent history does indeed repeat itself then investors are more likely than not going to divert into “risk-off” mode, where riskier assets like the stock markets and emerging assets suffer from low attraction and safe-haven assets like Gold and the Japanese Yen surge from buying demand.

Politics to continue influencing the Pound’s direction

After suffering its heaviest week of losses so far in 2017, the British Pound is attempting to consolidate around 1.28 against the US Dollar. I personally think that politics will continue to influence the direction of the British Pound and I believe that there is further momentum for the currency to fall with the UK General Election being a little over a week away. In general, the markets do not like uncertainty and this is the recurring theme for the UK at present with another election around the corner and ongoing Brexit uncertainty continuing to dominate news headlines.

My view is that even following the dip lower from the 2017 highs above 1.30 is that the financial markets are still underpricing the risk of an unexpected outcome to the election next week. Investors in general stacked their cards heavily in favour of Theresa May being declared the winner following the unexpected calling of a snap election, but opinion polls are currently showing that the race to win the election is going to be close. I can’t help but think that recent history could be repeating itself with the markets currently underpricing the risk of an outcome that could differ to what the markets expect, which is a Conservative victory on 8 June.

USD JPY – a game of politics vs economics

The British Pound is not alone in being underpinned to political risk, with politics vs. economics being the name of the game when it comes to trading the USDJPY. I believe that politics will continue to dictate the direction of this pair as we head into the second half of 2017, and I am actually favouring towards the Japanese Yen covering further ground against its counterparts on the back of safe-haven buying.

A lack of optimism around the likelihood that President Trump will be able to push forward with his legislative reforms will put the spotlight firmly on Washington, and I think that this will result in further pressure on the USD. Any further market uncertainty in the United States will eventually lead to investors being lured back into the safe-haven appeal of the Yen.

EUR USD – facing near-term selling pressure

The likelihood that the ECB will repeat its dovish rhetoric during its Central Bank meeting in June is encouraging traders to enter selling positions on the Eurodollar after the pair reached new 2017 milestone highs above 1.12 last week. Despite economic data around Europe continuing to improve confidence that the economy has turned a corner, the market is swaying towards the belief that the ECB will repeat in June that the economy still requires ECB stimulus and this could result in the Eurodollar slipping further towards 1.10.

The United Kingdom gave up its use of coal

The United Kingdom gave up its use of coal

Following our Earth Day commemoration article Climate Change and Environmental Awareness , where it was mentioned that on that day, the United Kingdom gave up its use of coal for mainly generating its electrical power, today we are happy to republish a World Economic Forum’s article written by Alex Gray, Formative Content on April 26, 2017 on the same subject. It is about the US and Europe abandoning coal generated energy altogether and for the first time for generations, in fact from as it were the launching of this technology.

The media are increasingly reporting that renewable power now accounts for more than 30% of all installed electrical capacity worldwide, exceeding coal, and this whilst some politicians who riding a wave crest of popularity have promised the contrary, that is to dig deep for more coal.

We would take opportunity here to mention that despite the advent of fossil oils, the coal industry never ceased to be sourced for one purpose or another to generate and / or second energy production.
As per this article, Alex is proposing the idea that this is it and there is no looking back.  So, thank you Alex for this piece of good news; wondering however, what’s next?

Coal mining jobs aren’t coming back. But clean energy is already creating millions of new ones

The benefits of renewable energy are obvious: it’s giving us a cleaner, healthier and more sustainable planet to live on.

But clean energy is also a massive contributor to the economy.

recent report says that “advanced energy” is a $1.4 trillion global industry, almost twice the size of the global airline industry, and nearly equal to worldwide apparel revenue. This is a 7% increase compared to the 2015 total of $1.3 trillion.

Image: Advanced Energy Now 2017 Market Report

In fact, the advanced energy industry, which encompasses energy sources, technologies and services that are clean, affordable and secure, is also growing much faster than the world economy overall – 7% versus 3.1%.

And it is creating jobs. The industry now supports 3.3 million positions in the US alone. That’s equal to the employment provided by retail stores, and twice the jobs in construction.

What is driving its growth?

Globally, advanced energy has grown by nearly a quarter (24%) since 2011, adding $257.7 billion in revenue over six years. The top three performers were electricity generation, transportation and building efficiency, in that order, according to the report, which was prepared by Navigant Research for Advanced Energy Economy (AEE), a trade association representing the advanced energy industry.

Electricity generation remained the largest advanced energy segment globally, with $455.6 billion in revenue (up 5% over 2015).

Transportation was the second largest advanced energy segment, growing 8% last year and reaching $447 billion.

At 15%, building efficiency capped a fifth straight year of double-digit growth with a record increase, reaching $271.6 billion in revenue in 2016.

The picture in the US

In the US, the advanced energy industry generated $200 billion in revenue, nearly double that of beer sales, equal to pharmaceutical manufacturing, and approaching wholesale consumer electronics.

Image: Advanced Energy Now 2017 Market Report

Advanced energy in the United States has grown by an average of 5% annually for a total of 28% compared to 2011.

What is advanced energy?

The report defines advanced energy as “a broad range of technologies, products, and services that constitute the best available technologies for meeting energy needs today and tomorrow”.

That includes things like the transmission, distribution and storage of electricity; vehicles that are powered by fuel other than gasoline or diesel; fuel production including ethanol and biodiesel; advanced industry processes (such as combined heat and power); fuel delivery and electricity generation through renewables.

Another report has reached similar conclusions.

The International Renewable Energy Agency (IRENA) says that, by 2050, renewables will add about $19 trillion to the world economy, and will create about 6 million jobs.

The increase in use of renewable energy, plus improved energy efficiency, will achieve the emissions reductions needed to keep global temperature rises to no more than 2C, according to IRENA. The aim of the Paris Agreement on Climate Change is to keep global temperature increase well below 2C and if possible below 1.5C.

IRENA says that while changing the energy landscape requires massive investment – some $29 trillion –
this only represents 0.4% of global GDP.

In addition to boosting the economy, it will create enough jobs to offset job losses in the fossil fuel industry, and of course, give us a healthier planet to live on.

Renewable energy now accounts for 24% of global power generation and 16% of primary energy supply. To achieve decarbonization, the report states that, by 2050, renewables should be 80% of power generation and 65% of total primary energy supply.

 

After the shock and sorrow come the questions

After the shock and sorrow come the questions

After the shock and sorrow come the questions as put by The Mirror online this morning. The Mirror   goes on :
Were there failings by the security services?

Are we doing enough to detect and monitor those at risk of being radicalised?

Is the Government’s Prevent strategy working?

Why, when it was known the authorities always feared a Mumbai-style attack, was not more done to improve security at Parliament’s carriage gates?

So far we know little about Kent-born Khalid Masood.
Only by learning why he committed the atrocity and how, as seems likely, he was radicalised can we prevent others from following his warped and deadly path.
There are also questions for companies such as Google and why terror manuals, including guides to using cars as weapons of destruction, are so readily available online.
In all cases, and as elaborated on by AMEinfo in an editorial that deserves pondering on, there are always causes to such atrocities but also unfortunately consequences.

London attack: 5 shocking ways terrorism affects economies

As the world watched, an unnamed assailant went on a rampage on London’s streets on Wednesday. Four people lost their lives in the deadly attack near the Houses of Parliament.

Financial impact of the ugly incident is yet to be ascertained but one can assume it will be colossal as the metropolis came to a standstill as events unfurled.

Unfortunately, the world continues to lose more money than it invests as terrorism and violence increase grossly.

The economic impact of violence on the global economy in 2015 was $13.6 trillion in purchasing power parity (PPP) terms, according to the figures from Global Peace Index (GPI).

To put this in macroeconomic perspective, the figure amounted to 13.3 per cent of the world’s GDP and it was nearly 11 times the size of global foreign direct investment.

If the lost money was distributed equally across the globe, every person would have received $1,876.

Destruction of infrastructure

Any terrorist activity begins with physical damage to properties. Numerous buildings, roads, railways and airports have been destructed in such incidents. These take a very huge share of governments’ fiscal budgets. Also, factories, machines, vehicles, skilled labourers and other resources are eliminated during the course of violence. In addition, damages to utility resources will have both short-term and long-term impacts on economy.

Uncertainty in markets

Markets are highly vulnerable to any development that catches the attention of investors. After the globalisation, markets have been responding to news-making events even if they are taking place miles away in a different country or a region. Shares in stock markets worldwide had fallen in response to militant attacks in Paris last year.

Investor confidence

Insurgent attacks have the highest potential to dampen the confidence of investors. As risk appetite of businesses wanes, they would turn away from investing in new markets or expanding in existing geographies.

Last year Syria, Iraq and Afghanistan incurred the largest economic impact as a percentage of their GDP at 54, 54 and 45 per cent of GDP respectively, according to the GPI 2016 report.

Peacebuilding spending

Governments spend billions of dollars after militant attacks in order to avoid such occurrence in future. For stepping up military strength and acquiring new weapons and technology as well as boosting intelligence many of the countries across the world allocate nearly half of their budget.

Following a suspected bombing of a Russian plane in Sinai in 2015, Egypt invested some $50 million in airport security.

Tourism

The most immediate impact of any violence will be felt on a country’s tourism sector, which is the backbone of economy in many parts of the world.

In 2010, 14.7 million tourists visited Egypt’s beaches and ancient sites but five years later the number of travellers plunged to just 9.3m as the country witnessed popular uprising and an array of terrorist attacks.

People tend to cancel or postpone their holidays which directly affects airlines, tour operators, hotels, restaurants and retailers.

 

Between 1970 and January 2016, there have been more than 160 terrorist attacks targeted at hotels worldwide. Over the past five years alone, more than 40 hotel terrorist attacks have occurred, according to figures from security consultancy firm Restrata.

Botan Osman Managing Director of Restrata says that hotels have been seen as a soft target for terrorist attacks because they tend to have large, open spaces and attract a high number of visitors, many of whom are often foreigners.

“Hospitality targeted attacks may rise unless the industry takes a harder stance. This can be done whilst balancing the business needs of the hotel.”

“Examining the growth in hotel attacks demonstrates a worrying statistic, with a quarter of all hotel attacks since 1970 occurring in the past five years. Documented attacks within the hotel industry focus primarily on North African states where terror levels are already high, yet research suggests a number of hospitality premises in these areas are lacking in basic security design features,” Osman adds.
