Study That Argued EVs Aren’t Cleaner Gets an Update

Published

on

An anonymous reader shares an update to a 2017 study from the IVL Swedish Environmental Research Institute that claimed the manufacturing of big batteries for electric vehicles generates so much emissions that all later savings are canceled out. “Based on the data that it had to work with, the institute’s study put the emissions at 150-200 kilograms of CO2 per kilowatt-hour of lithium-ion battery capacity — one of the highest estimates that has been published,” reports Ars Technica. “But IVL recently took another pass at this effort, incorporating newer data and some slightly different methods. This new study puts the emissions at 61-106kg, depending on the energy sources and efficiencies of different manufacturing plants. That cuts the estimate in half and puts it much more in line with other studies.” From the report: So what accounts for the change, exactly? A few things are going on here. The first is a simple methodological change — this study leaves out emissions associated with recycling the battery, which accounted for 15kg of CO2 in the 2017 estimate. There are different ways to define the boundaries of such a life-cycle analysis, including “cradle-to-grave” methods that cover disposal and “cradle-to-gate” methods that cover up to the point you receive the car. To make apples-to-apples comparisons, you have to know what kind of estimate you’re looking at.

More importantly, the study took advantage of more recent data that measures emissions during critical steps in the manufacturing process. As the battery manufacturing industry matures, plants are running closer to capacity and with efficiency improvements. Battery chemistry, too, is shifting. […] The cathodes and anodes of these batteries are made by mixing materials in a solvent (water or otherwise) and then evaporating the solvent to leave a powder behind. This drying dominates the energy use of the manufacturing process. More recent measurements of this process in operating plants are a major source of the difference between the new study and the 2017 study, which estimated 1.6 time to 3 times greater energy use for drying.

The new version also acknowledges that the electricity used in the manufacturing process is coming from cleaner sources and could potentially come entirely from renewables. That helps bring the low end of the estimated range down. Of the estimated 61-106kg of CO2 emissions per kilowatt-hour of battery capacity, 59kg comes from the raw materials used in the battery. Then, the manufacturing process accounts for 2-47kg, depending on the mix of energy sources used. The 2017 study used a slightly higher number for raw materials — 60-70kg of CO2 — but estimated manufacturing emissions at 70-110kg. Then, it added emissions associated with recycling.

Flybe owners seek £100m government loan

Flybe’s owners are trying to borrow £100m as a short-term loan from the government.

Connect Airways has also agreed to put £20m extra cash into its troubled regional airline, according to sources.

The company confirmed last week it was seeking a loan on “commercial” terms but not how much it wanted to borrow.

At the time Flybe boss Mark Anderson told staff it had had “difficult days” but still had “a great future”. He said the loan would not be a bailout.

That would be on top of the £30m already promised.

News of the amount being sought by Flybe was first reported by the Financial Times newspaper. The airline declined to comment.

If it succeeds, it will be an unusual move by the government, which declined to assist Thomas Cook when it asked for a loan.

British Airways’ owner IAG has filed a complaint to the EU arguing that Flybe’s rescue breaches state aid rules.

EasyJet and Ryanair have said taxpayer funds should not be used to save a rival.

Flybe, which flies to 170 different destinations, has been struggling under the weight of an estimated £106m bill for air passenger duty as well as a slowdown in demand that has hurt the airline’s finances.

It services dozens of UK domestic routes that are not flown by other airlines, making it the largest carrier to fly out of some regional airports, like Newquay.

What parents can do to prevent teens from driving drunk

Published

on

By









Older teens who know that their parents disapprove of drinking are less likely to drive impaired as young adults, a new study finds.

“As kids get older, we tend to step away from them. We think: ‘They’ve got this.’ But if kids think we approve or disapprove of them drinking, that can have a powerful effect,” said lead author Dr Federico Vaca, director of the Yale Developmental Neurocognitive Driving Simulation Research Center in New Haven, Connecticut.

Binge-drinking episodes

The new study included nearly 2 800 American teens who were followed for seven years.

By grade 12, 42% said they’d had alcohol in the past month, and 25% had at least one binge-drinking episode. Binge drinking is defined as four or more drinks in two hours for women, and five or more for men.

Compared to those who did not binge-drink in grade 12, those who did were six times more likely to drive impaired two years later and more than twice as likely to drive impaired four years later.

Teens who binge-drank in grade 12 were also more likely to ride with an impaired driver, to have alcohol-related blackouts, and to indulge in extreme binges in subsequent years, according to the study. Extreme bingeing – 15 or more drinks on a single occasion – is a growing concern.

Great prevention power

However, the study also found that parents could reduce their teens’ future risk of impaired driving.

If teens in the 12th grade knew that their parents disapproved of drinking, it lowered the chances of their driving while impaired by 30% four years later, and of riding with an impaired driver by 20% one year later. It also lowered later odds of blackout by 20%.

“There is great prevention power in intentional parenting, and a strong, reliable, mutual relationship here can make all the difference in the world, including helping to identify the development of youth alcohol/drug use disorder and the need for specialised treatment services for addiction,” Vaca said in a Yale news release.

The study was published in the January issue of the journal Pediatrics.

Vardy’s injury not as bad as first feared: Rodgers

Published

on

By

London – Leicester manager Brendan Rodgers says Jamie Vardy’s glute injury is not as bad as first feared and he expects the club’s leading scorer to be back in action soon.

Vardy was forced off during the first half of Wednesday’s Premier League win against West Ham after initially trying to continue playing after he suffered the injury.

Vardy has scored 17 goals for Leicester this term, making him a key figure in the team’s unexpected surge into the top four.

It was feared the 33-year-old could be sidelined for several weeks in a blow to third-placed Leicester’s hopes of securing a spot in next season’s Champions League.

But while Vardy will not be involved in the FA Cup fourth round tie at Brentford on Saturday, Rodgers said there is an outside chance he could feature in Tuesday’s League Cup semi-final second leg against Aston Villa.

“He’s not available for the weekend and there will be a question mark for Tuesday, although it’s certainly not as serious as we first thought,” Rodgers told reporters on Friday.

“It’s not his hamstring, it’s a glute, so we’re hopeful for Tuesday, but there’s a little bit of work to do. He’ll get some work in with the medical team. He’ll stay with them for the weekend.

“He’s much better than directly after the game, when he was tight and sore and struggling to move. But today he was much better.”

Meanwhile, Leicester midfielder Nampalys Mendy was also injured in the first half against West Ham with a knee problem and Rodgers said he will be out for up to six weeks.

Champion Tanak ‘fine’ after spectacular Monte Carlo crash

Published

By

Gap – World champion Ott Tanak and his co-driver escaped unscathed on Friday after their Hyundai somersaulted off an Alpine road at high speed in the Monte Carlo Rally.

WATCH | Tänak crashes out of Monte Carlo Rally

“Precautionary medical checks have confirmed that Ott Tanak and Martin Jarveoja are fine following their crash,” the team said in a statement after the pair had been checked over in hospital where they were due to remain overnight.

“But the Estonians will take no further part in the rally,” it added.

The Korean carmaker added that it had recovered the wrecked car.

Tanak, in his first rally for his new team, flew off an icy road on the fourth stage between Saint-Clement and Freissinieres.

The car’s nose dipped and hit the ground bouncing the vehicle into the air. It spun through a tree before landing 100m down the hillside.

The two Estonians miraculously climbed out of the car unscathed.

“I don’t know what happened,” said Hyundai team manager Andrea Adamo after the stage. “You saw what I saw, I’m waiting for him to come back but I was mostly concerned about his physical health.”

“Our priority in such situations is always the condition of the crew first and foremost,” Adamo later said. “It is customary after such incidents for hospital check-ups, the results of which were clear. They will remain there for monitoring overnight, which is again routine procedure.”

Tanak, 32, has never won the Monte Carlo Rally. He was in fourth place overall when he crashed.

His new team-mate Thierry Neuville was leading going into the stage but finished third.

“I was slowed down so much in that section,” Neuville, a Belgian, said. “I knew there was something when I saw Ott’s lines, so I lost quite a lot of time.”

Frenchman Sebastien Ogier, in a Toyota, finished second in the stage in which Tanak crashed.

“I hope Ott is okay,” the six-time former champion said. “It was a very fast section where he went off with a big compression.”

Welshman Elfyn Evans won the three morning sections to take the overall lead and held it even though Ogier took the first two afternoon stages as conditions changed as rain began to muddy the course.

Overnight temperature was below freezing and while there is not a lot of snow on the roads, there were still the patches of ice that had made the route difficult since the start the previous day.

After the two stages on Thursday evening. Tanak had complained about black ice and said: “I am happy to be alive!”

Several other drivers have been forced to retire after going off the road, including Britain’s Gus Greensmith (M-Sport Ford).

Beware bank using Moneyweb’s logo, warns financial regulator

Published

on

By

The Financial Sector Conduct Authority has warned the public against a business which calls itself Moneyweb Private Bank, saying it is “fraudulently using” the logo of the financial news website to solicit investments. 

In a statement issued on Friday afternoon, the FSCA said it had “reason to believe” that Moneyweb Private Bank Limited was operating unlawfully as a financial services provider by rendering financial services without authorisation. 

The financial publication, Moneyweb itself, has released statements clarifying that it does not offer money transfer services. 

In its statement, the FSCA said operating unlawfully as a financial services provider could attract a hefty penalty.

“Any entities or individuals rendering financial services without a licence or being appointed as representatives are acting in contravention of the FAIS Act. Such a contravention is an offence which carries a fine not exceeding R10m or a period of imprisonment not exceeding 10 years,” the statement said.

The statement said Moneyweb Private Bank was not authorised in terms of the Financial Advisory and Intermediary Services Act of 2002 to render any financial advice and intermediary services.

“According to information received by the FSCA, Moneyweb Private Bank is fraudulently using the logo of Moneyweb – a South African media company, to solicit investments from the public,” the statement said.

The FSCA urged members of the public to check that an entity or individual is registered with the authority to provide financial advisory and intermediary services.

The authority said some businesses registered to provide basic advisory services for a low-risk product offered services of a far more complex and risky nature.
