Facing Unbearable Heat, Qatar Has Begun To Air-Condition the Outdoors

It was 116 degrees Fahrenheit in the shade outside the new Al Janoub soccer stadium, and the air felt to air-conditioning expert Saud Ghani as if God had pointed “a giant hair dryer” at Qatar. Yet inside the open-air stadium, a cool breeze was blowing. Beneath each of the 40,000 seats, small grates adorned with Arabic-style patterns were pushing out cool air at ankle level. And since cool air sinks, waves of it rolled gently down to the grassy playing field. Vents the size of soccer balls fed more cold air onto the field. Ghani, an engineering professor at Qatar University, designed the system at Al Janoub, one of eight stadiums that the tiny but fabulously rich Qatar must get in shape for the 2022 World Cup. His breakthrough realization was that he had to cool only people, not the upper reaches of the stadium — a graceful structure designed by the famed Zaha Hadid Architects and inspired by traditional boats known as dhows. “I don’t need to cool the birds,” Ghani said.

Qatar, the world’s leading exporter of liquefied natural gas, may be able to cool its stadiums, but it cannot cool the entire country. Fears that the hundreds of thousands of soccer fans might wilt or even die while shuttling between stadiums and metros and hotels in the unforgiving summer heat prompted the decision to delay the World Cup by five months. It is now scheduled for November, during Qatar’s milder winter. The change in the World Cup date is a symptom of a larger problem — climate change. Already one of the hottest places on Earth, Qatar has seen average temperatures rise more than 2 degrees Celsius (3.6 F) above preindustrial times, the current international goal for limiting the damage of global warming. The 2015 Paris climate summit said it would be better to keep temperatures “well below” that, ideally to no more than 1.5 degrees Celsius (2.7 F).

[…] To survive the summer heat, Qatar not only air-conditions its soccer stadiums, but also the outdoors — in markets, along sidewalks, even at outdoor malls so people can window shop with a cool breeze. “If you turn off air conditioners, it will be unbearable. You cannot function effectively,” says Yousef al-Horr, founder of the Gulf Organization for Research and Development. Yet outdoor air conditioning is part of a vicious cycle. Carbon emissions create global warming, which creates the desire for air conditioning, which creates the need for burning fuels that emit more carbon dioxide. In Qatar, total cooling capacity is expected to nearly double from 2016 to 2030, according to the International District Cooling & Heating Conference. And it’s going to get hotter.

Killing tourist destinations for an Instagram photo

Overtourism is taking a toll across the globe, with closures of popular destinations in Thailand and the Philippines, and backlash from residents in cities like Venice and Barcelona. Closer to home, places like Bali, Byron Bay and parts of Tasmania have also been feeling pressure from skyrocketing visitors.

“The problem we’ve got is that we’re all congregating on the same places at the same time of the year,” says Justin Francis, CEO of the UK-based Responsible Travel.

Mr Francis says part of the problem is that the “ethos of travel” is changing: in the social media era, it’s now more about “where you want to be seen”. “Getting the photo and getting it on Instagram or Facebook is becoming the purpose of the trip — it’s the reason for going,” he says.

Travellers have also been drawn to places from their favourite films or TV shows, in a trend known as “set jetting”.

Energy cost of ‘mining’ bitcoin more than twice that of copper or gold

The amount of energy required to “mine” one dollar’s worth of bitcoin is more than twice that required to mine the same value of copper, gold or platinum, according to a new paper, suggesting that the virtual work that underpins bitcoin, ethereum and similar projects is more similar to real mining than anyone intended.

One dollar’s worth of bitcoin takes about 17 megajoules of energy to mine, according to researchers from the Oak Ridge Institute in Cincinnati, Ohio, compared with four, five and seven megajoules for copper, gold and platinum.

Other cryptocurrencies also fair poorly in comparison, the researchers write in the journal Nature Sustainability, ascribing a cost-per-dollar of 7MJ for ethereum and 14MJ for the privacy focused cryptocurrency monero. But all the cryptocurrencies examined come off well compared with aluminium, which takes an astonishing 122MJ to mine one dollar’s worth of ore.

Bitcoin Mining Now Accounts For Almost One Percent of the World’s Energy Consumption

It is well-established established that Bitcoin mining — aka, donating one’s computing power to keep a cryptocurrency network up and running in exchange for a chance to win some free crypto — uses a lot of electricity. Companies involved in large-scale mining operations know that this is a problem, and they’ve tried to employ various solutions for making the process more energy efficient.

But, according to testimony provided by Princeton computer scientist Arvind Narayanan to the Senate Committee on Energy and Natural Resources, no matter what you do to make cryptocurrency mining harware greener, it’s a drop in the bucket compared to the overall network’s flabbergasting energy consumption. Instead, Narayanan told the committee, the only thing that really determines how much energy Bitcoin uses is its price. “If the price of a cryptocurrency goes up, more energy will be used in mining it; if it goes down, less energy will be used,” he told the committee. “Little else matters. In particular, the increasing energy efficiency of mining hardware has essentially no impact on energy consumption.”

In his testimony, Narayanan estimates that Bitcoin mining now uses about five gigawatts of electricity per day (in May, estimates of Bitcoin power consumption were about half of that). He adds that when you’ve got a computer racing with all its might to earn a free Bitcoin, it’s going to be running hot as hell, which means you’re probably using even more electricity to keep the computer cool so it doesn’t die and/or burn down your entire mining center, which probably makes the overall cost associated with mining even higher.

The Ultra-Pure, Super-Secret Sand That Makes Your Phone Possible

Alex Glover is a recently retired geologist who has spent decades hunting for valuable minerals in the hillsides and hollows of the Appalachian Mountains that surround Spruce Pine, North Carolina. The wooded mountains surrounding it, though, are rich in all kinds of desirable rocks, some valued for their industrial uses, some for their pure prettiness. But it’s the mineral in Glover’s bag — snowy white grains, soft as powdered sugar — that is by far the most important these days. It’s quartz, but not just any quartz. Spruce Pine, it turns out, is the source of the purest natural quartz — a species of pristine sand — ever found on Earth.

This ultra-elite deposit of silicon dioxide particles plays a key role in manufacturing the silicon used to make computer chips. In fact, there’s an excellent chance the chip that makes your laptop or cell phone work was made using sand from this obscure Appalachian backwater. Most of the world’s sand grains are composed of quartz, which is a form of silicon dioxide, also known as silica. High-purity silicon dioxide particles are the essential raw materials from which we make computer chips, fiber-optic cables, and other high-tech hardware — the physical components on which the virtual world runs.

The Hidden Environmental Cost of Amazon Prime’s Free, Fast Shipping

Amazon has changed the way Americans shop. This year, the e-commerce giant said its annual Prime Day sale was “the biggest shopping event in Amazon history.” During the 36-hour event, people bought over 100 million products, crashed the website, and signed up for more Prime memberships than ever before. The behavior is indicative of the buying culture Amazon created. The company’s ease, speed, and savings — underscored by killer perks like free, expedited shipping and simple returns — has encouraged more people to shop online, more often.

But these free benefits come with a hidden environmental cost that doesn’t show up on the checkout page, experts say. Expedited shipping means your packages may not be as consolidated as they could be, leading to more cars and trucks required to deliver them, and an increase in packaging waste, which researchers have found is adding more congestion to our cities, pollutants to our air, and cardboard to our landfills.

“People are consuming more. There’s more demand created by the availability of these cheap products and cheap delivery options.”

Almost 45 million tons of e-waste discarded last year

A new study claims 44.7 million metric tons (49.3 million tons) of TV sets, refrigerators, cellphones and other electrical good were discarded last year, with only a fifth recycled to recover the valuable raw materials inside.

The U.N.-backed study published Wednesday calculates that the amount of e-waste thrown away in 2016 included a million tons of chargers alone.

The U.S. accounted for 6.3 million metric tons, partly due to the fact that the American market for heavy goods is saturated.

The study says all the gold, silver, copper and other valuable materials would have been worth $55 billion had they been recovered.

The authors of the Global E-waste Monitor predict that e-waste, defined as anything with a battery or a cord, will increase to 52.2 million metric tons by 2021.

The “Surprisingly” Large Energy Footprint of the Digital Economy

“Our computers and smartphones might seem “clean,” but the digital economy uses a tenth of the world’s electricity—and that share will only increase, with serious consequences for the economy and the environment.

The global Information-Communications-Technologies (ICT) system now uses approximately 1,500 terawatt-hours of power per year. That’s about 10% of the world’s total electricity generation or roughly the combined power production of Germany and Japan. It’s the same amount of electricity that was used to light the entire planet in 1985. We already use 50% more energy to move bytes than we do to move planes in global aviation.

Reduced to personal terms, although charging up a single tablet or smart phone requires a negligible amount of electricity, using either to watch an hour of video weekly consumes annually more electricity in the remote networks than two new refrigerators use in a year. And as the world continues to electrify, migrating towards one refrigerator per household, it also evolves towards several smartphones and equivalent per person.”

“Does reading an e-book, or watching a streaming video, use more energy than reading it on paper, or buying a DVD? Does playing a video game use more energy than playing Monopoly? Does a doctor using an iPad for diagnostic advice from artificial intelligence in the Cloud use more energy than, what? Traveling for a second opinion?  The answer involves more than knowing how much electricity one iPad, PC or smartphone uses. It requires accounting for all the electricity used in the entire ICT ecosystem needed to make any of that possible, and the energy characteristics of the ICT ecosystem are quite unlike anything else built to date. Turning on a light does not require dozens of lights to turn on elsewhere. However, turn on an iPad to watch a video and iPad-like devices all over the country, even all over the world, simultaneously light up throughout a vast network. Nothing else in society operates that way. Starting a car doesn’t cause dozens of cars elsewhere to fire up.”

A “shocking” amount of e-waste “recycling” is bogus

“Forty percent of all U.S. electronics recyclers testers included in [a study that used GPS trackers to follow e-waste over the course of two years] proved to be complete shams, with e-waste getting shipped wholesale to landfills in Hong Kong, China, and developing nations in Africa and Asia.

Rather than recycle them domestically, the recycling companies sell them to junkyards in developing nations, either through middlemen or directly. These foreign junkyards hire low-wage employees to pick through the few valuable components of often toxic old machines. The toxic machines are then left in the scrapyards or dumped nearby. Using GPS trackers, industry watchdog Basel Action Network found that 40 percent of electronics recyclers it tested in the United States fall into this “scam recycling” category.”
