Renewable Energy Booming After a Decade of Progress
The sun is rising on a newer, cleaner era of American energy use.
The U.S. generates nearly eight times as much electricity from the sun and the wind than it did in 2007—enough to power more than 25 million homes—and the average American uses 10 percent less energy than he or she did 10 years ago, according to a new report by Environment America Research and Policy Center.
The report, Renewables on the Rise: A Decade of Progress Toward a Clean Energy Future, also cites a 20-fold increase in battery storage of electricity and the meteoric rise in sales of electric cars—from virtually none in 2007 to nearly 160,000 last year—as evidence that despite attempted rollbacks in Washington, a clean energy revolution is under way across the U.S.
"Despite anti-science, anti-clean energy rhetoric coming from the Trump administration and many in Congress, the science is clear—fossil fuels pollute our air, water and land, threatening our health and changing our climate even faster than scientists predicted," said Rob Sargent, energy program director for Environment America Research and Policy Center. "The good news is that the progress we've made in the last decade on renewable energy, energy savings and technologies such as battery storage and electric cars should give us the confidence that renewable energy can be America's energy choice."
The new report, authored by Environment America Research & Policy Center and Frontier Group; analyzes the growth of key technologies needed to power the nation with clean, renewable energy; including wind, solar, energy efficiency, energy storage and electric vehicles. Beyond a national assessment, the report provides state by state rankings on how effectively each state is adopting these crucial technologies.
W/ @FrontierGroupUS, thrilled to release Renewables on the Rise report! Renewables have made huge progress in 10yrs… https://t.co/CU56W5uIKh— Environment America (@Environment America)1501078517.0
"Key clean energy technologies are improving rapidly and getting cheaper seemingly every day," said Gideon Weissman of Frontier Group, report co-author. "These and other advances open up new opportunities to end our dependence on fossil fuels and embrace a future built on clean, renewable energy."
The report describes the factors that have contributed to the rapid growth in each category, including improved technologies and plummeting costs. Citing a survey by the U.S. Department of Energy, the report says that between 2008 to 2015, the cost of land-based wind energy fell by 41 percent; the cost of onsite and rooftop solar photovoltaics (PV) by 54 percent; the cost of utility-scale PV by 64 percent; the cost of home energy storage batteries by 73 percent; and the cost of LED light bulbs fell by 94 percent.
"Every day, we see more evidence that an economy powered by renewable energy is within our reach," said Sargent. "We need to seize the moment and lean into a future powered by clean, renewable energy."
The report comes as a growing number of U.S. cities, states, corporations and institutions consider commitments to 100 percent renewable energy. Currently, 37 cities have committed to that goal. Nearly 100 major companies, including Apple, Walmart and LEGO have as well. Hawaii is committed to 100 percent renewable electricity by 2045. California and Massachusetts are currently considering similar legislation. And, in Washington, bills to commit the nation to 100 percent renewable energy have been introduced in both houses of Congress.

"Given the environmental benefits, clean, renewable energy should be the go-to option for businesses, utilities, governments and households across the country," said Sargent. "It won't be easy. But we have no choice. Every day the urgency of our environmental challenges becomes clearer. That's why we're ready to work to move America to a future powered with clean, renewable energy."

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>
