Is There Enough Metal to Replace Oil?

The short answer: No, not even close!

The short answer: No, not even close!

Nations of the world are only too aware that fossil fuels need to be phased out for two reasons. First, oil is a finite commodity. It’ll run out in time. Secondly, fossil fuel emissions such as CO2 are destroying the planet’s climate system.

However, a recent study puts a damper on the prospects of phasing out fossil fuels in favor of renewables. More to the point, a phase out of fossil fuels by mid century looks to be a nearly impossible Sisyphean task. It’s all about quantities of minerals/metals contained in Mother Earth. There aren’t enough.

Simon Michaux, PhD, Geological Survey Finland has done a detailed study of what’s required to phase out fossil fuels in favor of renewables, to wit:

“The quantity of metal required to make just one generation of renewable tech units to replace fossil fuels is much larger than first thought. Current mining production of these metals is not even close to meeting demand. Current reported mineral reserves are also not enough in size. Most concerning is copper as one of the flagged shortfalls. Exploration for more at required volumes will be difficult, with this seminar addressing these issues.” (Source: Simon P. Michaux, Associate Research Professor of Geometallurgy Unit Minerals Processing and Materials Research, Geological Survey of Finland, August 18, 2022 – Seminar: What Would It Take To Replace The Existing Fossil Fuel System?)

Metals/minerals required to source gigafactories producing renewables to power the world’s economies when fossil fuels phase out looks to be one of the biggest quandaries of all time. There’s not enough metal.

Michaux researched and analyzed the current status of the internal combustion engine fleet of cars, trucks, rail, maritime shipping, and aviation for the US, Europe, and China, accessing databases to gather information as a starting point for the study.

Michaux’s calculations for what’s required to phase out fossil fuels uses a starting point of 2018 with 84.5% of primary energy still fossil fuel-based and less than 1% of the world’s vehicle fleet electric. Therefore, the first generation of renewable energy is only now coming on stream, meaning there will be no recycling availability of production materials for some time. Production will have to be sourced from mining.

When Michaux presented basic information to EU analysts, it was a shock to them. To his dismay, they had not put together the various mineral/metal data requirements to phase out fossil fuels and replaced by renewables. They assumed, using guesstimates, the metals would be available.

A key issue for the accomplishment of renewables is power storage because of the impact of wind and solar intermittency, both of which are highly intermittent. Most studies assume gas will be the buffer for intermittency. Other than using fossil fuel such as gas as a buffer, an adequate power storage system to handle intermittency will require 30 times more material than what electric vehicles require with current plans, meaning the scope is much larger than the current paradigm allows.

One factor that will influence what materials and systems are used to build out renewables is the fact that EVs require a battery that is 3.2 times the mass of the equivalent of a hydrogen fuel tank. Therefore, an analysis of EVs versus hydrogen fuel cells indicates it’ll be necessary to build out the global fleet with EVs for city traffic and hydrogen fuel cells for all long-range vehicles like semi-trailers, rails, and maritime shipping.

The entire renewable build-out requires 36,000 terawatt hours to operate, meaning 586,000 new non-fossil fuel power stations of average size. The current fleet of power stations is only 46,000, meaning it’ll take 10 times the current number of power stations, yet to be built.

The new annual energy capacity of 36,007.9 terrawatt hours will supply (1) 29 million EV Buses (2) 601.3 million Commercial EV Vans (3) 695.2 million EV Passenger Cars (4) 28.9 million H2-Cell Trucks (5) 62 million EV Motorcycles (6). Hydro will also need to be expanded by 115% by 2050 and nuclear will need to double. Biomass will stay the same. It’s already at limitations. Geothermal triples.

Additionally, buffer systems are crucial to handle intermittency. For example, Hornsdale Power Reserve in Australia, which is an Elon Musk project with a 100-megawatt capacity. The EU is using Hornsdale as the standard buffer system. Globally, 15,635,478 Hornsdale-type stations will need to be built across the planet and connected to the power grid system just to meet a 4-week buffer system. This is 30 times the capacity compared to the entire global vehicle fleet. Therefore the market for batteries is substantially larger than currently understood and accounted for in planning for a renewable economy.

The International Energy Agency (IEA) released a report on how much metal is required per unit to build out a renewable economy. As well as a study of what 2040 market share would look like for batteries for light duty vehicles and heavy duty vehicles and power storage at the level of the global fleet for solar panels in 2040 and hydrogen fuel cells, trucks, freight locomotives, maritime shipping, wind turbines and power storage buffer.

The total metals required for one generation of technology to phase out fossil fuels is listed by Required Production followed by Known Reserves for all metals based upon tonnes, as follows:

Copper 4,575,523,674 vs. 880,000,000 – a serious shortfall -reserves only cover 20% of requirements.

Zinc 35,704,918 vs. 250,000,000 – adequate reserves.

Manganese 227,889,504 vs 1,500,000,000 – adequate reserves

Nickel 940,578,114 vs. 95,000,000 – huge shortfall – reserves 10% of requirements.

Lithium 944,150,293 vs. 95,000,000 = huge shortfall – reserves 10% of requirements.

Cobalt 218,396,990 vs. 7,600,000 – huge shortfall – reserves 3.48% of requirements.

Graphite 8,973,640,257 vs. 320,000,000 = huge shortfall – 3.57% reserves of requirements.

Silicon (metallurgical) 49,571,460 – adequate reserves

Silver 145,579 vs. 530,000 – adequate reserves

Vanadium 681,865,986 vs. 24,000,000= huge shortfall -3.52% reserves of requirement

Zirconium 2,614,126 vs.70, 000,000 – adequate reserves.

Prior to 2020- the global system mined 700 million tons of copper throughout all history. Looking forward, the same 700 million tons will need to be mined over the next 22 years, which is based upon current economic growth rates without giving consideration to what’s needed for one generation of renewables.

Current reserves of copper are 880 million tons. But 4.5 billion tons of copper are required just to manufacture one generation of renewable technology. Hmm.

Moreover, each renewable technology has a life cycle of 8 to 25 years. Thereafter, they need to be decommissioned and replaced. Also, whether renewables are strong enough, and sustainably enough to power the next industrial era is a question that hangs in the air.

THE PAST – “An industrial ecosystem of unprecedented size and complexity, that took more than a century to build with the support of the highest calorifically dense source of cheap energy the world has ever known (oil) in abundant quantities, with easily available credit, and unlimited mineral resources.” (Michaux)

THE PRESENT – “We now seek to build an even more complex system with very expensive energy, a fragile finance system saturated in debt, not enough minerals, with an unprecedented number of the human population, embedded in a deteriorating environment.” (Michaux)

Current mineral reserves are not adequate to resource metal production to manufacture the generation of renewable energy technology, as current mining is not even close to meeting the expected demand for one generation of renewable technology.

Time is Running Out to Upgrade US Immigration Policy


 
 AUGUST 25, 2022
Facebook

Between ludicrously long backlogs and outdated policy, the current state of the American immigration system is a lose-lose. But, if Congress acts quickly, they might be able to change that.

The U.S. currently has a processing backlog of about 1.4 million employment-based green card applications, which — barring extensive reform of immigration policy — is on pace to take almost two centuries to complete. This year’s annual defense bill will likely be Congress’ only chance to resolve this issue for several years to come.

The green card pileup mainly affects skilled workers from countries with the largest populations. At the current rates, about 200,000 skilled Indian immigrants are likely to die before they receive a green card, a process that is expected to take until the year 2216, a whopping 194 years from now. In addition, hundreds of thousands of foreign-born children of H1-B visas will have to switch over to international student visas or self-deport, despite having lived in the country legally for nearly their entire lives. The only way to resolve this issue is to include the original versions of the National Defense Authorization Act (NDAA) and U.S. Innovation and Competitiveness Act (USICA) in this year’s defense bill.

The U.S. economy depends on skilled immigrant labor, now more than ever. In 1990, Congress set an annual limit on employment-based green cards at 140,000 and temporary H1-B visas at 65,000. This limit has failed to keep pace with rapid technological advances which have dramatically accelerated the demand for high-skilled workers. The centuries-long current backlog for green card holders is not only unnecessary — it’s actively harmful.

report from the National Association of Manufacturing and Deloitte found that the United States will have 2 million unfilled STEM jobs by 2025 due to a lack of qualified candidates. These jobs can’t be filled domestically, and the shortage is crippling the United States’ ability to compete on the world stage. China now produces over twice as many engineers per capita as the U.S., as domestic enrollment in programs such as electrical engineering continues to decline.

The original USICA included exemptions for STEM advanced-degree holders from annual limits on green cards, helping high-skilled immigrants from countries like India and China to avoid protracted visa backlogs, and attracting more international students. The Senate version of the bill guts these provisions, and House Minority Leader Kevin McCarthy (R-Calif.) has declared that he will not bring any immigration bills to the floor should Republicans take the majority in the upcoming midterms. The only way to resolve the backlog and put the United States on a trajectory to alleviate the dire STEM worker shortage is to pass the original USICA in this year’s defense bill.

In addition to green card backlogs, there are about 200,000 foreign-born children of H1-B workers facing deportation when they turn 21, colloquially referred to as “documented dreamers.” Dr. Dinsha Mistree, a Research Fellow at the Hoover Institution, explains, “We’ve got a lot of people who have come here as children of H-1Bs at the age of six months. Because of the current process, their parents won’t be eligible for green cards until those kids are twenty or thirty. When you’re 21, you are no longer eligible to be sponsored by your parents. So we’re going to have a number of kids here legally who are going to come of age, and then at 21, they’re going to have to get a university or employer to sponsor them, or they’re going to have to go to their home countries, which they haven’t lived in their entire lives.” The documented dreamer problem, in addition to creating chaos and uncertainty for so many children, has severe negative ramifications for the country at large.

Aside from the humanitarian challenges posed by the mass deportation of children who have been legally raised in America,  the situation also raises economic concerns. Taxpayers invest hundreds of thousands of dollars to educate each child. Deporting them would render that investment wasted. The NDAA includes a bipartisan provision to protect the children of green card applicants who face deportation when they age out of eligibility to remain on their parents’ visas. Failure to pass this act as part of this year’s defense bill could have catastrophic impacts.

All in all, U.S. immigration policy has failed to keep pace with the changing economic landscape, creating chaos in the lives of millions of immigrants, worsening the STEM worker shortage, and threatening future economic prosperity. Given the likely Republican midterm victory, and the subsequent moratorium on immigration bills being brought to the floor as a result, this year’s defense bill marks the last opportunity to resolve these issues for the foreseeable future.

Policymakers need to act now.

The Tight Connections Between Slavery and War

 

AUGUST 24, 2022

Some 40 million people are enslaved around the world today, though estimates vary. Modern slavery takes many different forms, including child soldiers, sex trafficking and forced labor, and no country is immune. From cases of family controlled sex trafficking in the United States to the enslavement of fishermen in Southeast Asia’s seafood industry and forced labor in the global electronics supply chain, enslavement knows no bounds.

As scholars of modern slavery, we seek to understand how and why human beings are still bought, owned and sold in the 21st century, in hopes of shaping policies to eradicate these crimes.

Many of the answers trace back to causes like poverty, corruption and inequality. But they also stem from something less discussed: war.

In 2016, the United Nations Security Council named modern slavery a serious concern in areas affected by armed conflict. But researchers still know little about the specifics of how slavery and war are intertwined.

We recently published research analyzing data on armed conflicts around the world to better understand this relationship.

What we found was staggering: The vast majority of armed conflict between 1989 and 2016 used some kind of slavery.

Coding conflict

We used data from an established database about war, the Uppsala Conflict Data Program (UCDP), to look at how much, and in what ways, armed conflict intersects with different forms of contemporary slavery.

Our project was inspired by two leading scholars of sexual violence, Dara Kay Cohen and Ragnhild Nordås. These political scientists used that database to produce their own pioneering database about how rape is used as a weapon of war.

The Uppsala database breaks each conflict into two sides. Side A represents a nation state, and Side B is typically one or more nonstate actors, such as rebel groups or insurgents.

Using that data, our research team examined instances of different forms of slavery, including sex trafficking and forced marriage, child soldiers, forced labor and general human trafficking. This analysis included information from 171 different armed conflicts. Because the use of slavery changes over time, we broke multiyear conflicts into separate “conflict-years” to study them one year at a time, for a total of 1,113 separate cases.

Coding each case to determine what forms of slavery were used, if any, was a challenge. We compared information from a variety of sources, including human rights organizations like Amnesty International and Human Rights Watch, scholarly accounts, journalists’ reporting and documents from governmental and intergovernmental organizations.

Alarming numbers

In our recently published analysis, we found that contemporary slavery is a regular feature of armed conflict. Among the 1,113 cases we analyzed, 87% contained child soldiers – meaning fighters age 15 and younger – 34% included sexual exploitation and forced marriage, about 24% included forced labor and almost 17% included human trafficking.

A global heat map of the frequency of these armed conflicts over time paints a sobering picture. Most conflicts involving enslavement take place in low-income countries, often referred to as the Global South.

About 12% of the conflicts involving some form of enslavement took place in India, where there are several conflicts between the government and nonstate actors. Teen militants are involved in conflicts such as the insurgency in Kashmir and the separatist movement in Assam. About 8% of cases took place in Myanmar, 5% in Ethiopia, 5% in the Philippines and about 3% in Afghanistan, Sudan, Turkey, Colombia, Pakistan, Uganda, Algeria and Iraq.

This evidence of enslavement predominately in the Global South may not be surprising, given how poverty and inequality can fuel instability and conflict. However, it helps us reflect upon how these countries’ historic, economic and geopolitical relationships to the Global North also fuel pressure and violence, a theme we hope slavery researchers can study in the future.

Strategic enslavement

Typically, when armed conflict involves slavery, it’s being used for tactical aims: building weapons, for example, or constructing roads and other infrastructure projects to fight a war. But sometimes, slavery is used strategically, as part of an overarching strategy. In the Holocaust, the Nazis used “strategic slavery” in what they called “extermination through labor.” Today, as in the past, strategic slavery is normally part of a larger strategy of genocide.

We found that “strategic enslavement” took place in about 17% of cases. In other words, enslavement was one of the primary objectives of about 17% of the conflicts we examined, and often served the goal of genocide. One example is the Islamic State’s enslavement of the Yazidi minority in the 2014 massacre in Sinjar, Iraq. In addition to killing Yazidis, the Islamic State sought to enslave and impregnate women for systematic ethnic cleansing, attempting to eliminate the ethnic identity of the Yazidi through forced rape.

The connections between slavery and conflict are vicious but still not well understood. Our next steps include coding historic cases of slavery and conflict going back to World War II, such as how Nazi Germany used forced labor and how Imperial Japan’s military used sexual enslavement. We have published a new data set, “Contemporary Slavery in Armed Conflict,” and hope other researchers will also use it to help better understand and prevent future violence.

More Young Americans are Using Cannabis and Hallucinogens. That’s Good News.


  AUGUST 25, 2022

According to a recent National Institutes of Health survey, United Press International reports, “use of marijuana and hallucinogens among young adults in the United States reached an all-time high in 2021.”

According to the survey, 43% of young adults admitted to having used cannabis in the past year, with 8% saying they’ve tried LSD, psilocybin mushrooms, or other “hallucinogens.”

That, believe it or not, is good news.  Both of these “drug” categories have a history of use as long as the history of humanity, with known medical and mental benefits, few negative side effects, and virtually no correlation to violent behaviors.

None of these items should have ever been illegal to use, possess, sell, or grow/manufacture in the first place, and increasing familiarity with them continues to feed  growing opposition to the  “war on drugs.”

They’re all, in three words, “safer than alcohol.”

Which, the same survey says, remains the most popular “drug,” with binge drinking rebounding from a 2020 low and “high-intensity” drinking steadily increasing.

That’s the bad news.

If I knew one of my children (all now thankfully and safely out of their teens) was going out to “party,” and that recreational substances would be involved, I’d much rather they got into a bag of weed or some mushroom caps than into a case of beer or a fifth of bourbon. There’s just less potential for senseless brawls, sexual assault, or driving while impaired.

Don’t get me wrong. I’ve personally got nothing against alcohol, and don’t think it should be illegal. I use it, although these days I drink maybe a six-pack of beer and a few ounces of whiskey a year; it used to be … well, quite a bit more.

Here’s the thing:

People have both self-medicated and recreationally dosed themselves with various things since there have been humans.

They’ll keep doing so, even if politicians get together and decree that they mustn’t.

The choice we face is not between a society of junkies and a “drug-free America.” History has taught us that neither of those things is going to happen.

The choice is between a society where we’re free to choose what we eat, drink, smoke, or otherwise ingest — and are responsible for what follows — or a society where eating, drinking, smoking, or otherwise ingesting the “wrong” substance may mean prison whether we harmed anyone else or not.

We’re moving in the former direction. And should continue to do so.

Yoga Versus Democracy?

As the United States gets less religious, is it also getting more selfish?

Historically, religious Americans have been civically engaged. Through churches and other faith-based organizations, congregants volunteer, engage in local and national civic organizations and pursue political goals.

Today – the rise of a politically potent religious right over the past 50 years notwithstanding – fewer Americans identify with formal religions. Gallup found that 47% of Americans reported church membership in 2020, down from 70% in the 1990s; nearly a quarter of Americans have no religious affiliation.

Meanwhile, other kinds of meaningful practice are on the rise, from meditation and yoga to new secular rituals like Sunday assemblies “without God.” Between 2012 and 2017, the percentage of American adults who meditated rose from 4.1% to 14.2%, according to a 2018 CDC report. The number of those who practiced yoga jumped from 9.5% to 14.3%. Not everyone considers these practices “spiritual,” but many do pursue them as an alternative to religious engagement.

Some critics question whether this new focus on mindfulness and self-care is making Americans more self-centered. They suggest religiously disengaged Americans are channeling their energies into themselves and their careers rather than into civic pursuits that may benefit the public.

As sociologists who study religion and public life, we wanted to answer that question. We used survey data to compare how these two groups of spiritual and religious Americans vote, volunteer and otherwise get involved in their communities.

Spiritually selfish or religiously alienated?

Our research began with the assumption that moving from organized religious practices to spiritual practices could have one of two effects on greater American society.

Spiritual practice could lead people to focus on more selfish or self-interested pursuits, such as their own personal development and career progress, to the detriment of U.S. society and democracy.

This is the argument sociologist Carolyn Chen pursues in her new book “Work, Pray, Code,” about how meditators in Silicon Valley are re-imagining Buddhist practices as productivity tools. As one employee described a company mindfulness program, it helped her “self-manage” and “not get triggered.” While these skills made her happier and gave her “the clarity to handle the complex problems of the company,” Chen shows how they also teach employees to put work first, sacrificing other kinds of social connection.

Bringing spiritual practice into the office may give workers deeper purpose and meaning, but Chen says it can have some unintended consequences.

When workplaces fulfill workers’ most personal needs – providing not only meals and laundry but also recreational activities, spiritual coaches and mindfulness sessions – skilled workers end up spending most of their time at work. They invest in their company’s social capital rather than building ties with their neighbors, religious congregations and other civic groups. They are less likely to frequent local businesses.

Chen suggests that this disinvestment in community can ultimately lead to cuts in public services and weaken democracy.

Alternatively, our research posited, spiritual practices may serve as a substitute for religion. This explanation may hold especially true among Americans disaffected by the rightward lurch that now divides many congregations, exacerbating cultural fissures around race, gender and sexual orientation.

“They loved to tell me my sexuality doesn’t define me,” one 25-year-old former evangelical, Christian Ethan Stalker, told the Religion News Service in 2021 in describing his former church. “But they shoved a handful of verses down my throat that completely sexualize me as a gay person and … dismissed who I am as a complex human being. That was a huge problem for me.”

Engaged on all fronts

To answer our research question about spirituality and civic engagement, we used a new nationally representative survey of Americans studied in 2020.

We examined the political behaviors of people who engaged in activities such as yoga, meditation, making art, walking in nature, praying and attending religious services. The political activities we measured included voting, volunteering, contacting representatives, protesting and donating to political campaigns.

We then compared those behaviors, distinguishing between people who see these activities as spiritual and those who see the same activities as religious.

Our new study, published in the journal American Sociological Review, finds that spiritual practitioners are just as likely to engage in political activities as the religious.

After we controlled for demographic factors such as age, race and gender, frequent spiritual practitioners were about 30% more likely than nonpractitioners to report doing at least one political activity in the past year. Likewise, devoted religious practitioners were also about 30% more likely to report one of these political behaviors than respondents who do not practice religion.

In other words, we found heightened political engagement among both the religious and spiritual, compared with other people.

Our findings bolster similar conclusions made recently by sociologist Brian Steensland and his colleagues in another studyon spiritual people and civic involvement.

Uncovering the spiritual as a political force

The spiritual practitioners we identified seemed particularly likely to be disaffected by the rightward turn in some congregations in recent years. On average, Democrats, women and people who identified as lesbian, gay and bisexual reported more frequent spiritual practices.

We suspect these groups are engaging in American politics in innovative ways, such as through online groups and retreats that re-imagine spiritual community and democratic engagement.

Our research recognizes progressive spiritual practitioners as a growing but largely unrecognized, underestimated and misunderstood political force.

In his influential book “Bowling Alone,” Harvard political scientist Robert Putnam suggests American religious disaffiliation is part of a larger trend of overall civic decline. Americans have been disengaging for decades from all kinds of civic groups, from bowling leagues and unions to parent-teacher organizations.

Our study gives good reason to reassess what being an “engaged citizen” means in the 21st century. People may change what they do on a Sunday morning, but checking out of church doesn’t necessarily imply checking out of the political process.
