25% of Australian Homes have gone Solar and other Green Triumphs this Week

by Juan Cole

Juan Cole is the Richard P. Mitchell Professor of History and the director of the Center for South Asian Studies at the University of Michigan. His latest book, Engaging the Muslim World, is just out in a revised paperback edition from Palgrave Macmillan. He runs the Informed Commentwebsite.

Renewables continue to take the world by storm, which is good news for the climate.

Because of less expensive and more efficient technology, about one quarter of all Australian households now have solar panels. This process is uneven, with a rush to put them up recently because of a fall in the price of the panels. The adoption of solar may slow next year. But the technology is such that there will certainly be more periods of rapid adoption. Before you know it, all Australian homes will be run on solar power. Incidentally, if you run an electric car off the solar panels, it causes the payback period to fall for both. Even OPEC and big oil have vastly increased their estimate of the number of electric vehicles on the road in 2040.

Case Western Reserve University scientists have found a way to boost panel output by 10%, and the breakthrough is now being tested for durability. If you follow these things, such reports of improved solar efficiency or fall in costs (which is the same thing) are quite common. The potential for technological breakthroughs is so high given the R&D money being thrown at solar research that all projections about the future are ‘way too conservative.

A new University of Minnesota study finds that solar power plus battery storage is now, in summer 2017, already cheaper than natural gas.

There will be resistance to this march to solar, but it can be overcome. Big Carbon and the utilities had bought up Florida politicians and put in punitive taxes on home solar installations. But as the cost of the panels has fallen in recent years, homeowners began really minding this punitive policy. So they got a pro-solar law on a referendum and it passed. Even governor Rick Scott, who probably gargles with gasoline, felt constrained to sign the law approved in the referendum into law. Popular insistence on cheap energy where it is available will over time undermine the hold that Big Carbon has on our politicians. It is expected that the new legislation will much increase the number of commercial solar installations; businesses with no fuel bill are better positioned to compete. And solar jobs in Florida are soaring.

Scientific and commercial expertise in solar power, of which Trump wants to rob us, will turn into large overseas contracts. An Indian firm has been hired by Japan to install 150 MW of solar-driven electricity.

I have solar panels and my average power bill over the past two months has been $15 a month.

This march to solar is heartening. The 35 billion metric tons of toxic carbon dioxide gas we are spewing into the atmosphere like an open sewer are melting the world’s ice cover and will raise sea levels. We are already locked in to some amount of rising sea level because we’ve raised the parts per million of CO2 in the atmosphere from 270 ppm to over 400 ppm since the Revolutionary War. Carbon Dioxide is a deadly greenhouse gas that prevents the heat striking the earth’s surface from radiating back out into space.

James Hansen, the father of contemporary climate science, worries that since half of the world’s large cities are on the seacoasts, as people flee inland there will be a good deal of social turmoil and countries could become “ungovernable.”

Climate change should be thought of as on a spectrum. We have a choice of going up by 3.6 degrees F. (2 degrees C.) or of going up by 15 degrees F., which would melt all surface ice over several centuries and make the tropics and sub-tropics uninhabitable. How hot it gets depends on how much gasoline/ petrol, natural gas and coal you and I burn, releasing CO2 into the air.

EXTRACT: " The sad reality is that the Mizrahim (Jews of Middle Eastern and North African descent) were discriminated against from the day of Israel’s inception, whose Ashkenazi (European Jewish) leaders viewed them as intellectually inferior, “backward,” and “too Arab,” and treated them as such, largely because the Ashkenazim agenda was to maintain their upper-class status while controlling the levers of power, which remain prevalent to this day." ..... " The greatest heartbreaking outcome is that for yet another generation of Israelis, growing up in these debilitating conditions has a direct effect on their cognitive development. A 2015 study published in Nature Neuroscience found that “family income is significantly correlated with children’s brain size…increases in income were associated with the greatest increases in brain surface area among the poorest children.” "

In a short 24-minute film, The Present, she has exposed the oppressive indecency of the Israeli occupation while telling the deeply moving story of a Palestinian family. What is especially exciting is that after winning awards at a number of international film festivals​, Ms. Nabulsi has been nominated for an Academy Award for this remarkable work of art. "

What I didn’t know was that my brain was sloshing around inside my skull, causing a mild concussion. Nor did I know that I was in for a whole new world of weird and wonderful hallucinations."

EXTRACT: "Overall, our review has found that there isn’t evidence to back up the claims that veganism is good for your heart. But that is partly because there are few studies ....... But veganism may have other health benefits. Vegans have been found to have a healthier weight and lower blood glucose levels than those who consume meat and dairy. They are also less likely to develop cancer, high blood pressure and diabetes. "

EXTRACT: "Pollock’s universe, the universe of Mural, cannot be said to be a rational universe. Nor is it simply devoid of all sense. It is not a purely imaginary world, although in it everything is in a constant state of flux. Mural invokes one of the oldest questions of philosophy, a question going back to the Pre-Socratic philosophers Parmenides and Heraclitus – namely, whether the nature of Reality constitutes unchanging permanence or constant movement and flux. For Pollock, the only thing that is truly unchanging is change itself. The only certainty is that all is uncertain."

EXTRACT: "Many present day politicians appear to have psychopathic and narcissistic traits too. It’s easy to spot such leaders, because they are always authoritarian, following hardline policies. They try to subvert democracy, to reduce the freedom of the press and clamp down on dissent. They are obsessed with national prestige, and often persecute minority groups. And they are always corrupt and lacking in moral principles."

EXTRACT: "This has led some to claim that not just half, but perhaps nearly all advertising money is wasted, at least online. There are similar results outside of commerce. One review of field experiments in political campaigning argued “the best estimate of the effects of campaign contact and advertising on Americans’ candidates choices in general elections is zero”. Zero!"

EXTRACT: "Picasso was 26 in 1907, when he completed the Demoiselles; de Kooning was 48 in 1952, when he finished Woman I.  The difference in their ages was not an accident, for studies of hundreds of painters have revealed a striking regularity - the conceptual painters who preconceive their paintings, from Raphael to Warhol, consistently make their greatest contributions earlier in their careers than experimental painters, from Rembrandt to Pollock, who paint directly, without preparatory studies."

EXTRACT: "There are two main rival models of ethics: one is based on rights, the other on duties. The rights-based model, which traces its philosophical origins to the work of John Locke in the 17th century, starts from the assumption that individuals have rights ....... According to this approach, duties are related to rights, but only in a subordinate role. My right to health implies a duty on my country to provide some healthcare services, to the best of its abilities. This is arguably the dominant interpretation when philosophers talk about rights, including human rights." ........ "Your right to get sick, or to risk getting sick, could imply a duty on others to look after you during your illness." ..... "The pre-eminence of rights in our moral compass has vindicated unacceptable levels of selfishness. It is imperative to undertake a fundamental duty not to get sick, and to do everything in our means to avoid causing others to get sick. Morally speaking, duties should come first and should not be subordinated to rights." ..... "Putting duties before rights is not a new, revolutionary idea. In fact it is one of the oldest rules in the book of ethics. Primum non nocere, or first do no harm, is the core principle in the Hippocratic Oath historically taken by doctors, widely attributed to the ancient Greek philosopher and physician Hippocrates. It is also a fundamental principle in the moral philosophy of the Roman statesman Marcus Tullius Cicero, who in De Officiis (On Duties) argues that the first task of justice is to prevent men and women from causing harm to others."

EXTRACT: "Several studies have recently compared the difference between antibodies produced straight after a coronavirus infection and those that can be detected six months later. The findings have been both impressive and reassuring. Although there are fewer coronavirus-specific antibodies detectable in the blood six months after infection, the antibodies that remain have undergone significant changes. …….. the “mature” antibodies were better at recognising the variants."

EXTRACT: "Like Shakespeare, Goya sees evil as something existing in itself – indeed, the horror of evil arises precisely from its excess. It overflows and refuses to be contained by or integrated into our categories of reason or comprehension. By its very nature, evil refuses to remain within prescribed bounds – to remain fixed, say, within an economy where evil is counterbalanced by good. Evil is always excess of evil." ....... "Nowhere is this more evident than in war. Goya offers us a profound and sustained meditation on the nature of war ........ The image of a Napoleonic soldier gazing indifferently on a man who has been summarily hanged, probably by his own belt, expresses the tragedy of war – its dehumanization of both war’s victims and victors."

EXTRACT: "A blockchain company has bought a piece of Banksy artwork and burnt it. But instead of destroying the value of the art, they claim to have made it more valuable, because it was sold as a piece of blockchain art. The company behind the stunt, called Injective Protocol, bought the screen print from a New York gallery. They then live-streamed its burning on the Twitter account BurntBanksy. But why would anyone buy a piece of art just to burn it? Understanding the answer requires us to delve into the tricky world of blockchain or “NFT” art."

EXTRACT: "Exercise is good for your health at every age – and you can reap the benefits no matter how late in life you start. But our latest research has shown another benefit of being physically active throughout life. We found that in the US, people who were more physically active as teenagers and throughout adulthood had lower healthcare costs."

EXTRACT: "Although around one in 14 people over 65 have Alzheimer’s disease, there’s still no cure, and no way to prevent the disease from progressing. But a recent study may bring us one step closer to preventing Alzheimer’s. The trial, which was conducted on animals, has found a specific molecule can prevent the buildup of a toxic protein known to cause Alzheimer’s in the brain."

EXTRACT: "The art historian George Kubler observed that scholars in the humanities “pretend to despise measurement because of its ‘scientific’ nature.” As if to illustrate his point Robert Storr, former dean of Yale’s School of Art, declared that artistic success is “completely unquantifiable.” In fact, however, artistic success can be quantified, in several ways. One of these is based on the analysis of texts produced by art scholars, and this measure can give us a systematic understanding of how changes in recent art have produced changes in the canon of art history."

EXTRACT: ".... these men were completely unaware that they had put their lives in the hands of doctors who not only had no intention of healing them but were committed to observing them until the final autopsy – since it was believed that an autopsy alone could scientifically confirm the study’s findings. As one researcher wrote in a 1933 letter to a colleague, “As I see, we have no further interest in these patients until they die.” ...... The unquestionable ethical failure of Tuskegee is one with which we must grapple, and of which we must never lose sight, lest we allow such moral disasters to repeat themselves. "
