Environmental impact of cryptocurrency

Ten years ago, an anonymous cryptographer laid out the principles of an online currency that would operate beyond the reach of governments and central banks. — dpa

BITCOIN was supposed to solve the problems of analogue currencies. Instead, it created a new one: an enormous amount of global energy consumption that rivals the power usage of an entire country like Ireland.

According to findings of a new study, the implementation of this cryptocurrency could lead to enough emissions being produced so that global temperatures rise 2°C by 2033.

The study, which was published in the journal Nature Climate Change, found that the hardware and electricity needs of Bitcoin alone could significantly impact climate change for the worse.

“Currently, the emissions from transportation, housing and food are considered the main contributors to ongoing climate change. This research illustrates that Bitcoin should be added to this list,” said Katie Taladay, one of the paper’s co-authors from the University of Hawaii at Manoa.

The technical design of how transactions are processed causes Bitcoin and many of the growing numbers of rival cryptocurrencies to consume an enormous amount of energy in so-called Bitcoin mining centres around the world.

And yet the digital currency Bitcoin is still enjoying hype as one of the greatest financial phenomenons of our time.

The foundation for Bitcoin was laid out 10 years ago when an anonymous cryptographer using the name “Satoshi Nakamoto” published a paper laying out the principles for autonomous digital money.

The ideas it contained were revolutionary: No control by central banks, no national borders.

Instead, a mechanism called blockchain would provide trust and security in the system. In broad strokes, blockchain is a publicly viewable ledger of transactions, each saved one after the other.

But as the cryptocurrency’s wild fluctuations and electricity needs have attracted a lot of media attention, the ramifications of the latter have only recently been brought to light.

In a different article published in May by financial economist and blockchain specialist Alex de Vries, the electricity consumption of Bitcoin was estimated to be around the same as the electricity use of the Republic of Ireland.

De Vries also predicted that Bitcoin could be using as much as half of a percent of the world’s total electricity consumption by the end of this year.

“To me, half a percent is already quite shocking. It’s an extreme difference compared to the regular financial system, and this increasing electricity demand is definitely not going to help us reach our climate goals,” de Vries said.

“With the ever-growing devastation created by hazardous climate conditions, humanity is coming to terms with the fact that climate change is as real and personal as it can be,” said Camilo Mora, associate professor of geography in the College of Social Sciences at UH Manoa, Hawaii.

“Clearly, any further development of cryptocurrencies should critically aim to reduce electricity demand,” Mora, the lead author of the new study warns.

So as Bitcoin celebrates 10 years since its creation and it gains more and more supporters each year, we should probably take a moment and give this energy-sucking technology a re-think. – dpa By AMY WALKER

Europeans migrate south as continent deepens into crisis

Tens of thousands of Irish, Greek and Portuguese people leave in search of a new life as the eurozone's woes worsen

Since its conception, the European Union has been a haven for those seeking refuge from war, persecution and poverty in other parts of the world. But as the EU faces what Angela Merkel has called its toughest hour since the second world war, the tables appear to be turning. A new stream of migrants is leaving the continent. It threatens to become a torrent if the debt crisis continues to worsen.

Tens of thousands of Portuguese, Greek and Irish people have left their homelands this year, many heading for the southern hemisphere. Anecdotal evidence points to the same happening in Spain and Italy.

The Guardian has spoken to dozens of Europeans who have left, or are planning to leave. Their stories highlight surprising new migration routes – from Lisbon to Luanda, Dublin to Perth, Barcelona to Buenos Aires – as well as more traditional migration patterns.

This year, 2,500 Greek citizens have moved to Australia and another 40,000 have "expressed interest" in moving south. Ireland's central statistics office has projected that 50,000 people will have left the republic by the end of the year, many for Australia and the US.



Portugal's foreign ministry reports that at least 10,000 people have left for oil-rich Angola. On 31 October, there were 97,616 Portuguese people registered in the consulates in Luanda and Benguela, almost double the number in 2005.

The Portuguese are also heading to other former colonies, such as Mozambique and Brazil. According to Brazilian government figures, the number of foreigners legally living in Brazil rose to 1.47 million in June, up more than 50% from 961,877 last December. Not all are Europeans, but the number of Portuguese alone has jumped from 276,000 in 2010 to nearly 330,000.

Gonçalo Pires, a graphic designer who has swapped Lisbon for Rio de Janeiro, said: "It's a pretty depressing environment there [in Portugal]." In Brazil, by contrast, "there are lots of opportunities to find work, to find clients and projects".

Joy Drosis, who left her Greek homeland for a life in Australia, expressed similar motives.  "I had to do something. If I had stayed in Greece, we were all doomed," she said. "I'm lucky that I can speak the language: many others can't."

The key moment in this southerly migration may have come last month, when the Portuguese prime minister, Pedro Passos Coelho, made a humbling visit to Angola, begging for inbound investment. Just 36 years after the end of Portuguese colonial rule in Angola, its president was ready to show mercy.

"We're aware of the difficulties the Portuguese people have faced recently," said José Eduardo dos Santos. "Angola is open and available to help Portugal face this crisis."

But the Portuguese making this move will not have it easy: life expectancy in Angola is still just 39, compared with 79 in Portugal, and crime is rife.

In Ireland, where 14.5% of the population are jobless, emigration has climbed steadily since 2008, when Lehman Brothers collapsed and the bottom fell out of the Irish housing market. In the 12 months to April this year, 40,200 Irish passport-holders left, up from 27,700 the previous year, according to the central statistics office. Irish nationals were by far the largest constituent group among emigrants, at almost 53%.

The Guardian spoke to one Dublin under-19s football and hurling club that had lost eight out of 15 players in the past 18 months. Most of the nascent sports stars had headed to Australia. Experts believe the exodus will increase, given the £1.4bn tax rises and austerity measures just announced. The thinktank the Economic and Social Research Institute (ESRI) forecast this month that 75,000 people would emigrate from Ireland in 2012 .

For departing Greeks the top destinations over the years, according to the World Bank, have been Germany, Australia, Canada, Albania, Turkey, UK, Cyprus, Israel and Belgium.

Skilled Greeks are particularly likely to leave: as an example of what can happen, 4,886 physicians emigrated in the year 2000 (the last year for which the World Bank's Migration and Remittances Factbook cites data for departing doctors), meaning the country lost 9.4% of its doctors in that single year.

The World Bank gives the number of immigrants living in Greece as about 1.13 million in 2010, around 10% of the population. Most have come, over the years, from poorer countries such as Albania, Bulgaria, Romania and Georgia, it is likely that the majority of new arrivals lack the skills to replace the emigrants.

• This article was amended on 22 December 2011 to delete a sentence reading: "In 2010, 1.21 million people emigrated [from Greece], according to the World Bank, equalling 10.8% of the population." This was actually the total "stock" of Greeks said by the World Bank to be living overseas as of 2010, not the number who emigrated in that year. Also deleted was a reference stating that "1.3 million people arrived [in Greece] in 2011". This was the total "stock" of immigrants said by the World Bank to be living in Greece as of 2010, not the number who arrived in that year. A sentence saying that 4,886 physicians emigrated from Greece in 2010 has been corrected; the year was 2000.

The New Generation Leaving Ireland, now rated to junk by Moody




Some 170,000 jobs vanished last year, and the lack of employment is driving a generation away

http://images.businessweek.com/mz/10/08/600/1008_mz_50ireland.jpg "The lack of jobs is driving people away," says Trinity College senior Simon Phelan Jude Edginton
Dublin - When Simon Phelan started a civil engineering degree at Dublin's Trinity College four years ago, he figured his biggest problem upon graduation would be deciding which job to choose. Ireland's economy was growing at 5.4%, unemployment was a mere 4.4%, and construction was booming.

Today, with graduation fast approaching, only two of Phelan's 100 classmates have even had interviews. Worse, in these recession-scarred times, just two people from the class ahead of him are employed. So Phelan and many contemporaries see emigration as the only option. "The lack of jobs is driving people away," the 20-year-old Dubliner says after trawling through the meager offerings at Trinity's career office, a small building tucked off the school's cobblestoned quadrangle. "Ireland will lose a whole generation of graduates."

It's a scenario most Irish thought had gone the way of the potato famine and two-shilling pints of Guinness. Two decades of prosperity had transformed the island nation of 4.5 million from a European laggard into the so-called Celtic Tiger. After a century and a half in which Ireland's young and energetic routinely fled to South Boston or London's Kilburn, today's twentysomethings grew up expecting to live and work at home. But with one in three males under age 25 out of work, their confidence seems to have been misplaced. "It used to be employers were fighting over graduates," says Shane King, a 22-year-old Trinity senior from County Mayo on Ireland's west coast. "Now graduates are fighting each other for jobs."

The country's budget swung from a surplus in 2007 to a deficit of nearly 12% of gross domestic product last year as the economy shrank by 7.5%. A decade-long property bubble, which saw real estate prices triple, led to a banking crisis that Standard & Poor's estimates could cost taxpayers as much as $34 billion. "Everything we have is being spent on the banks," says David Begg, head of the Irish Congress of Trade Unions.

Drive the 10 miles from central Dublin to Citywest, an industrial park near the border of County Kildare, and you'll see ample evidence of overbuilding. On the banks of the Liffey River, there's the half-finished shell of Anglo Irish Bank's new headquarters. Farther on, "for sale" signs dot posh developments where new homes stand unoccupied.

AUSTRALIA BOUND?

Many would-be emigrants have made the same trip. On a chilly Sunday, hundreds of people gather in a conference room at the Citywest Hotel for a seminar on emigrating Down Under. Representatives of several Aussie states sit behind foldable tables stacked with pamphlets extolling Australia's low unemployment and "no worries" outlook. Carpenter Michael McGerr, 38, drove more than 100 miles with his wife and toddler to attend. "Our goal is to go away for good," he says.

Last year emigration exceeded immigration for the first time in 15 years as 65,100 people left, outpacing arrivals by nearly 8,000. Almost half of those who decamped were recent immigrants from Eastern Europe. But with few opportunities at home, growing numbers of native Irish are also headed for the exit. "There was loads of work three years ago, then it just dried up," says Patrick Maye, an unemployed bricklayer who traveled to the Aussie seminar from Carlow, some 50 miles south of Dublin. The 22-year-old hopes to move to Australia once he finishes retraining as a fitness instructor.

With unemployment set to hit 13.8% this year, things are sure to get worse. The Economic & Social Research Institute (ESRI), an independent think tank in Dublin, predicts net outward migration of 40,000 for the year ending in April, the highest level in more than 20 years. "We are right back to the 1980s," says Piaras Mac Éinrí, a lecturer at University College Cork.

Back then, unemployment soared to 18% as the economy took a dive. Then in the 1990s, a wave of foreign investment swept Ireland, lured by low corporate taxes and inexpensive workers. Now the blue chips are scaling way back. In the past year, Intel (INTC), Royal Bank of Scotland (RBS), and Waterford Wedgwood have downsized; Dell (DELL) moved PC production from Limerick to lower-wage Poland; and some 1,500 smaller companies have folded. Last year 170,000 Irish jobs vanished, and ESRI predicts 76,000 more will be lost in 2010.

One problem is that Ireland got too pricey. The American Chamber of Commerce Ireland estimates that from 2004 to 2008, Irish wages rose 50% faster than the average of advanced European economies. Former Intel Chairman Craig R. Barrett says that of the 14 reasons Intel came to Ireland two decades ago, only one remained: a low corporate tax rate of 12.5%. "Ireland needs a new game plan," he said at a Dublin conference in September.

In the past, the state has been a big creator of jobs by hiring civil servants and promoting investment. But to plug a yawning gap in public finances, Dublin in December announced spending cuts of $5.6 billion, including $1.4 billion from public sector pay and $1.1 billion from social welfare benefits. The tough measures have helped restore Ireland's standing among global investors, but the cuts make it difficult for the government to launch the policies that might enable people to ride out the recession, either in on-the-job training or higher education.

The biggest job casualties have been in construction. At its peak in 2007, the building trade employed 1 in 7 Irish workers. But over the past two years, the sector has shed 200,000 jobs, according to Ireland's Construction Industry Federation. "We went from being in high demand to no demand," says Gordon Cobbe, a construction manager from Cork. Out of work for a year, he plans on moving to Perth, Australia.

Many Irish aiming to get out face problems similar to workers in, say, Detroit or Toledo: They can't afford to leave their homes. John McKenna is eager to join more than a dozen friends who have moved to Australia. With business slow at the plumbing supply store where he works, "I don't know how much longer I'll have a job," the 39-year-old says. But the house he bought for $306,000 in 2006 has halved in value, so it'll be tough to depart anytime soon.

The emigration surge comes as Dublin tries to implement a program called "Smart Economy." The plan is to boost innovation through tax breaks for research, expedited visa processing for skilled workers, a $689 million fund to back promising tech startups, and other incentives. The glue holding it all together, the government says, is "the knowledge, skills, and creativity" of the Irish—a problem with so many people leaving. "There is a risk that many of the talented individuals envisioned as the foundation of the innovation economy will make their careers elsewhere," says John McHale, an economics professor at the National University of Ireland, Galway.

Other economists are more optimistic. Alan Barrett, a research professor at ESRI, says the current exodus is likely to be benign. As part of the EU, Ireland will again lure immigrants from across Europe as growth picks up. And he points out that many who left in the '80s returned with better skills. "As soon as the economy recovered, people came back in droves," he says.

Kevin Carey, CEO of moving company Careline International, can attest to that. His firm helped relocate emigrants in the 1980s before bringing many back a decade later. Now most of his work is again outbound, and business was up 23% last year. His customers weren't so lucky. "They're all leaving; the cost of living here is too high," says Carey, who was manning a table at the Australian emigration event at the Citywest Hotel. For him, at least, business was good.

Moody's cuts Ireland to junk, warns of second bailout

NEW YORK/DUBLIN | Tue Jul 12, 2011 7:29pm EDT

Reuters) - Moody's cut Ireland's credit rating to junk on Tuesday, warning that the debt-laden country would likely need a second bailout -- just the latest move amid heightening concerns about Europe's ability to address its debt crisis and prevent it from spreading.

Moody's move comes a week after it slashed Portugal to junk status with a similar warning about the need for a second round of rescue funds. It reflects the credit rating agency's view that any further financial assistance from Brussels will require private investors to share part of the pain, possibly through a debt rollover or swap.

European finance ministers have acknowledged for the first time that some form of Greek default may be needed to cut Athens' debts, and if that materializes, Ireland's rating, never before in junk territory, could be set for a further round of cuts.

Investors fear a Greece default could ripple through Europe's banking system, putting pressure on stretched public finances in other euro zone countries. Italy, the euro zone's third largest economy, looks especially vulnerable with a debt-to-output ratio second only to Greece, and markets fear political bickering may derail a plan to slash spending and rein in the deficit.

Moody's one-notch downgrade on Ireland weighed on stocks and the euro, which hit its lowest level against the dollar in four months.

The Irish government, which wants to return to debt markets in 2013 when its current EU-IMF bailout runs out, offered a vexed response.

"This is a disappointing development and it is completely at odds with the recent views of other rating agencies," the finance ministry said in a statement. "We are doing all that we can to put our house in order and the progress that we are making is there for all to see."

Moody's now rates Ireland Ba1, one notch below former financial market pariah Colombia and two notches below Brazil, and has kept a negative outlook, meaning further downgrades are likely in the next 12 to 18 months.

Ireland's rating is still one notch above Portugal and six above Greece. Both Standard & Poor's and Fitch Ratings have Ireland at BBB-plus, three notches above junk status, with S&P's outlook stable and Fitch on outlook negative meaning it does not expect a downgrade in the short-term.

Moody's move, however, will likely put pressure on the other ratings as the downgrade forces some investors to dump Irish bonds because they no longer enjoy a clean investment-grade sweep of the three major ratings agencies.

"It's amazing to me that Ireland was still investment grade," said Suvrat Prakash, interest rate strategist at BNP Paribas in New York.

"A lot of people assume that these rating agencies tend to move with a lag so there could be more downgrades to come.

Ireland's borrowing costs are already at levels once thought unimaginable, with five-year paper yielding over 15 percent on the secondary market and 10-year paper close to euro-era highs of 13.86 percent.

When Ireland agreed an 85 billion euros ($119 billion) bailout package with the European Union and the International Monetary Fund last November -- a move designed to soothe market fears -- its 10-year paper was yielding around 9.5 percent, a level viewed as shocking at the time.

Economic growth in the European region as a whole has been sluggish, as a number of nations have struggled with mounting debt costs and have had to pass harsh austerity plans that have slowed economic growth further, creating a vicious cycle where tax revenues drop, reducing their chances of repaying the debt even more.

But the more investors fear that heavily indebted euro zone governments will be unable to repay their debts, the more the yields on their bonds rise, dragging down their value in banks' balance sheets, erasing their capital, and increasing the need for yet more bank bailout's by stronger euro zone governments.

A CORK BOBBING IN THE OCEAN

Unlike Greece, Ireland is meeting its bailout targets and Irish officials have felt frustrated at how their efforts have been swept aside by events in Athens.

An agreement by the euro zone finance ministers, known as the Eurogroup, late on Monday to cut the interest rate for countries borrowing from their rescue fund and an agreement to make the fund more flexible and extend its loan maturities was hailed by Dublin as helping it return to debt markets.

The finance ministry said Moody's move appeared not to reflect the Eurogroup developments, but Moody's analyst Dietmar Hornung said the risk of private sector participation in any future bailout meant investors would be put off lending fresh funds to Ireland.

Hornung, in an interview with Reuters, warned over the risks even though Moody's is confident the euro zone is "willing to continue to provide liquidity support for peripheral countries and give them time to achieve a sustainable financial position.

"But at the same time we see a growing possibility that, as a precondition of additional rounds of liquidity support here, private-sector creditors participation will be required," he said.

Ireland's debt management agency said on Tuesday the country was fully funded until the end of 2013. Ireland has a financing requirement of nearly 34 billion euros over 2014 and 2015, based on estimated deficits and maturing debts.

Even before Moody's downgrade, Finance Minister Michael Noonan admitted Dublin was at the mercy of the markets.

"Ireland is a cork bobbing on a very turbulent ocean at present," he told state broadcaster RTE on Tuesday.

Officials from the EU, the IMF and the European Central Bank are expected to confirm Dublin is meeting all its bailout targets in their latest quarterly review, expected on Thursday.

But Ireland's weak domestic economy is hitting spending-related tax revenues, and Moody's warned that another downgrade would be considered if the government can't meet its fiscal consolidation goals.
