World's Largest Solar Farm Leapfrogs India to Third in Utility-Scale Solar
The Kamuthi solar plant in the southern Indian state of Tamil Nadu has vastly expanded the country's solar capacity. Based on Wiki-Solar's calculations, thanks to the new plant, India now claims the number three spot in terms of utility-scale solar, behind China and the U.S.
World's largest single location power project was commissioned by Adani Group in the town of Kamuthi in Tamil Nadu. Adani Group
The 648-megawatt Kamuthi plant went online this September and is considered the world's largest solar project in a single location. For comparison, the world's second largest solar plant, the Topaz Solar Farm in California, has a capacity of 550 megawatts.

"India has now leap-frogged the UK, as predicted, to become the world's third nation for the deployment of utility-scale solar," Wiki-Solar founder Philip Wolfe stated. "India still has a huge backlog of awarded tenders, which should enable it to close the gap with the USA and China in coming years."

As Alternative Energies writes, "over the next five years, India plans to build a number of 25 extra large solar power plants with a generation capacity between 500 and 1,000 MW."
"The success of India's solar energy policy stems in part from the [Jawaharlal Nehru National Solar Mission] national program, but also the extent to which many states are supporting this effort," Wolfe continued. "The majority of Indian states have now designated one or more 'solar parks' where priority is given both to allocation of land and to provision of high capacity connections."
This push towards clean power cannot come soon enough. Earlier this month, the air pollution in the nation's capital of New Delhi was literally off the charts, earning it the dubious title of "world's most polluted city." Delhi Chief Minister Arvind Kejriwal declared the intense smog levels an "emergency situation," and ordered the shut down of 5,000 schools and halted construction operations for several days.

With the new plant in Kamuthi, India's total installed solar capacity has now crossed the important 10 gigawatt milestone, according to consultancy firm Bridge to India.
"The pace of sector activity has picked up tremendously in the last two years because of strong government support and increasing price competitiveness of solar power. India is expected to become the world's third biggest solar market from next year onwards after China and the US," Bridge to India stated.
In 2014, Indian Prime Minister Narendra Modi announced plans to increase India's solar power capacity to 100 gigawatts by 2022, a target that seems too ambitious for some.
"Many people are going to ask the obvious question—if we have taken more than 5 years to achieve 10 GW, can we reach 100 GW in another 5 years? It is a very steep target in our view," Bridge to India managing director Vinay Rustagi said. "But rather than quibble about the target, the important point is to acknowledge the transformational economic, environmental and social potential of solar technology and to create a conducive environment for its growth."
Aljazeera has published new footage of the Kamuthi facility that's spread across 10 square kilometers—or the equivalent of 60 Taj Mahals. The plant consists of 25,00,000 solar modules and can supply enough energy for 150,000 homes.
Adani Green Energy Ltd, built the impressive structure in only eight months thanks to the around-the-clock dedication of a 8,500-member team. Roughly 11 megawatts were installed in a day on average.
In September, Adani Group chairman Gautam Adani formally dedicated the solar structure to the nation.
"This is a momentous occasion for the state of Tamil Nadu as well as the entire country," he said. "We are extremely happy to dedicate this plant to the nation; a plant of this magnitude reinstates the country's ambitions of becoming one of the leading green energy producers in the world."

Summer and fall are great seasons to enjoy the outdoors. But if you're already spending extra time outside because of the COVID-19 pandemic, you may be out of ideas on how to make fresh-air activities feel special. Here are a few suggestions to keep both adults and children entertained and educated in the months ahead, many of which can be done from the comfort of one's home or backyard.
The coronavirus may linger in the air in crowded indoor spaces, spreading from one person to the next, the World Health Organization acknowledged on Thursday, as The New York Times reported. The announcement came just days after 239 scientists wrote a letter urging the WHO to consider that the novel coronavirus is lingering in indoor spaces and infecting people, as EcoWatch reported.

It is undisputed that vitamin D plays a role everywhere in the body and performs important functions. A severe vitamin D deficiency, which can occur at a level of 12 nanograms per milliliter of blood or less, leads to severe and painful bone deformations known as rickets in infants and young children and osteomalacia in adults. Unfortunately, this is where the scientific consensus ends.
Where Does the Deficiency Begin?<p>Nobody knows exactly how much vitamin D a person actually needs. The question of when a deficiency starts is correspondingly controversial. However, vitamin D is becoming increasingly popular.Not only is the pseudo-scientific literature on the "sun vitamin" experiencing an upswing, but the number of published studies has also increased enormously in recent years. For example, in 2019 <a href="https://academic.oup.com/edrv/article/40/4/1109/5126915" target="_blank">a study found that</a> Vitamin D is responsible for keeping the skeleton functional and is associated with cardiovascular diseases, type 2 diabetes and various types of cancer. <br></p>
An All-Rounder<p>Vitamin D levels in the body rise and fall according to sun exposure. If sufficient UV rays reach the skin, the body is able to produce the vitamin itself. However, the human body only derives an estimated 10 to 20 percent of its daily requirement from food.</p><p>The vitamin D that we synthesize from sunlight or food is not biologically active at first. Before the kidneys can produce the biologically active form of the vitamin, known as calcitriol, and release it into the blood, some metabolic processes must take place beforehand.</p><p>In addition, many organs have receptors to which the precursor of calcitriol binds. Further, this substance is also present in blood.</p><p>From this precursor, the organs then produce calcitriol themselves, which the body then uses for countless other processes in the body. This form of vitamin D thus regulates insulin secretion, inhibits tumor growth, and promotes the formation of red blood cells as well as the survival and activity of macrophages, which are important for the <a href="https://www.mdpi.com/2072-6643/5/7/2502/htm" target="_blank">immune system.</a></p>
Low Vitamin D, Severe COVID-19 Disease?<p>A research study carried out <a href="https://www.sciencedirect.com/science/article/pii/S2352364620300067?via%3Dihub" target="_blank">at the University of Hohenheim</a> has now established a link between vitamin D deficiency, certain previous diseases, and severe cases of COVID-19.</p><p>According to the study, "there is a lot of evidence that several non-communicable diseases (high blood pressure, diabetes, cardiovascular diseases, metabolic syndrome) are associated with low vitamin D plasma levels. These comorbidities, together with the often accompanying vitamin D deficiency, increase the risk of severe COVID-19 events."</p><p>"This statement is completely correct," said Martin Fassnacht, head of endocrinology at the University Hospital of Würzburg. However, he qualifies that it is a pure association, "i.e. a mere observation that these events occur together.</p><p>Dr. Fassnacht is very critical of the hype surrounding vitamin D, but not because he denies the vitamin serves important functions. However, studies on humans have not been able to show that vitamin D has the healing powers many often propagate.</p><p>Fassnacht says, "If you take a closer look, the hopes that the administration of vitamin D has a healing effect have not been confirmed so far."</p>
Association Versus Intervention Studies<p>Many studies on the vitamin are association or observational studies. "By definition, these studies cannot prove the causal relationship, but only point to mere correlations," said Fassnacht. The physician tries to illustrate this with an example:</p><p>"Imagine two groups of 80-year-olds. One group is spry, active and does sports. If you compare them with another group living in nursing homes, the difference in vitamin D levels will be dramatic. Life expectancy would also be extremely different."</p><p>But to try to explain the difference in fitness by vitamin D status alone is far too simplistic. "Vitamin D levels are a good measure of how sick someone is. But not more," says Fassnacht. </p><p>According to Fassnacht, none of the intervention studies carried out to date -- that specifically examined the effect of vitamin D on various diseases -- has been able to confirm the previous association and laboratory studies or the presumed positive effect of vitamin D.</p>
Further Research Is Needed<p>"If a coronavirus infection is suspected, it is therefore absolutely necessary to check the vitamin D status and quickly correct any possible deficit," said the recommendation of the paper published by the University of Hohenheim.</p><p>"Studies are underway to see whether vitamin D helps in COVID-19 infection, but I personally do not believe that this is really the case," says endocrinologist Fassnacht. Nevertheless, he says it is of course useful to carry out these studies.<br></p><p>"I don't want to rule out that there are actually subgroups of people who benefit from an additional vitamin D dose," he says. After all, this has been proven to be the case with a severe deficit.</p><p>In view of the study situation, Fassnacht does not think much of preventive, nationwide vitamin D substitutes. "My belief that the vitamin helps somewhere is very low. But, of course, I can be wrong."</p>
