Cheers to 2019 Energy Efficiency Progress
Reflecting on 2019, it is hard to grapple with the extent of this year's climate tragedies like massive wildfires and flooding. Yet even when things seem as dire as ever, there is continual news of progress, perseverance, and hope. And energy efficiency — the cheapest way to cut our energy waste and stave off climate change — is at the forefront of that progress and continues to be our planet's superhero, improving our health, creating high-quality jobs, and making our energy bills more affordable.
What's more, even as the U.S. builds more homes and commercial space, the amount of electricity needed to power those spaces (and the related pollution) is set to decline thanks to steady gains in efficiency.
States Led (And Continue to Lead) the Way
State Scorecard / ACEEE
With a Trump administration bent on stalling or dismantling efficiency efforts at every turn, states filled an important gap on setting efficiency standards (so our gadgets use less energy) and in delivering building upgrades (to cut energy waste and improve our comfort and health). The annual American Council for an Energy-Efficient Economy (ACEEE) scorecard shows where states are making progress and where more work is needed.
Here Are Just a Few State Examples:
- Washington, Colorado, and Hawaii adopted expanded energy and water efficiency standards, including for faucets, commercial kitchen equipment, computers, and more.
- Illinois is moving forward with the Clean Energy Jobs Act to require 100 percent clean energy by 2050, including a significant increase in gas efficiency, while ensuring that programs help the most vulnerable communities while creating good jobs.
- Missouri recently approved an improved set of efficiency programs that will help renters and owners of affordable multifamily housing cut costs and energy waste while protecting the health of residents.
- Michigan now has its first long-term outlook for how Consumers Energy will serve its customers with clean energy through its "clean and lean" plan, which includes an impressive increase of energy efficiency.
- New Jersey began implementing groundbreaking efficiency legislation to ensure its utilities invest in all cost-effective energy efficiency, positioning itself to become a national leader.
- New York adopted the nation-leading Climate Leadership and Community Protection Act setting a path to net-zero emissions (efficiency playing a major role) while helping to advance equity for disadvantaged communities.
- California adopted a new framework to launch innovative market transformation ideas to get even more efficient products onto store shelves, helping cut energy waste in the state and beyond as those improved technologies become the norm nationally.
Job and Emissions Benefits Were Made Crystal Clear

There is no doubt that with strong policies to ensure high-quality jobs (e.g., those with family-sustaining wages, good benefits, a safe work environment, and a path for advancement), efficiency can help spur significant work for all Americans.
An analysis from the group E2 identified 2.3 million energy efficiency jobs based on 2019 U.S. Energy and Employment Report data. Energy efficiency accounted for half of the energy industry's overall net new jobs in 2018 and employs twice as many U.S. workers as the entire fossil fuel industry. The workers who make buildings and equipment more efficient are earning good salaries in jobs that can't be outsourced. Many are military veterans, just another reason why this summer's passage of the appalling HB 6 bill gutting Ohio energy efficiency programs was such a terrible move for the state and its workers.
National Standards Despite Trump
Several new efficiency standards approved by previous administrations took effect this year. And while the Trump administration's DOE missed more legal deadlines for review of product standards, NRDC and others are holding them to account. A federal appeals court recently ordered the agency to take the final step on four standards, ensuring upward of $8.4 billion in utility bill savings and substantial reductions in carbon pollution.
Even with this great progress, we're still fighting over the rules for setting standards. The U.S. Department of Energy's (DOE) proposed new process would make it far more difficult to advance products that give us the same (or even better) service but use far less energy, which would mean lower energy bills.
We are far from where we need to be in terms of cutting greenhouse gases and serving all communities. As we reflect on 2019, we can learn from our successes and build upon our challenges to make even more progress in 2020.
- Make sure everyone has access to clean energy. Getting sufficient funding to serve the most vulnerable communities has been difficult, but the opportunities are enormous, including cutting energy waste, improving health, and reducing the energy burden. Focusing efforts on these communities will not only help stave off climate change, it will improve their well-being, stimulate investment in their neighborhoods, and ensure that everyone is part of the clean energy transition.
- Fight for our lighting rights. The Trump administration continues its crusade to turn back time on light bulbs. In its latest proposal, DOE would illegally permit energy-wasting versions of the regular pear-shaped bulbs to remain on store shelves indefinitely. California, however, is again leading the way on efficiency by prohibiting the sale of inefficient light bulbs in the state as of January 1, but the federal attacks on energy efficiency must end.
- Keep up the state level work. Given the administration's denial of climate change and focus on advancing industry interests at the expense of everyday Americans, states MUST continue their leadership. Many states have great efficiency policies in place and are poised for exciting progress, such as Virginia's opportunity to adopt an ambitious energy efficiency resource standard, but other states require more work. Governors across the country have stepped up on climate action. It's time to do even more.
There is no doubt that the climate crisis is real. But as we come to the end of a harrowing year for the earth, we have much to look forward to in 2020. Working in collaboration with equity and workforce advocates, industry, and governments, we can create scalable, comprehensive, and effective energy efficiency actions to cut pollution, make energy more affordable for everyone, clean our air, and create high-quality jobs.

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>
