Say Goodbye to the Internal Combustion Engine
By Rory Christian and Larissa Koehler
Electric vehicles (EVs) don't make much noise on the road, but they're generating a lot of buzz about the future of this technology and what it means for business and the environment.
Cars, buses and trucks are the second biggest source of pollution in the U.S. after electricity production. They are responsible for more than 26 percent of emissions that adversely affect the health and well-being of the population, and put communities located close to highways and other major thoroughfares at risk. These communities, typically low-income, are often plagued by elevated asthma rates and other pollution-induced health conditions.
When thinking about ways to reduce pollution, EVs can make a world of difference. And, when charged using renewable energy sources, they produce no emissions and can be much cheaper to operate than traditional, internal combustion vehicles. As such, let's take a look at the global EV market and impacts in the U.S. on the electric grid in two environmentally progressive states—New York and California.

The Global Market—and Future Outlook
More and more automakers are shifting their focus to EVs, a market that is expected to grow faster every year. A few examples:
- Tesla invested $5 billion in its Nevada gigafactory—where they will make batteries for EVs—and is grabbing headlines with the roll-out of its first mass-market EV, the Model 3.
- Volvo made waves by announcing its intent to focus new vehicle production solely on electric and hybrid vehicles. The company is owned by Geely Automotive holdings, a Chinese firm, and many speculate that China's pervasive air pollution problems and a desire to find a long-term solution were a motivating factor behind the announcement.
- Mercedes Benz is investing $740 million in a new battery factory.
These exciting developments all point to a trend where electric cars are much more than just a niche—indeed, they show that global competition is heating up quickly and that companies around the world see EVs as key to the automobile industry. These movements should not be understated, as it gives a hint of a clean energy future that can't come fast enough.
EVs on the Grid
Overall, strategic deployment of charging stations will be essential to EV growth—drivers need convenient places to charge. What's more ...
Here's what we can do now to prepare for a clean car economy:
- Chase innovation: Testing out more nascent technologies, such as vehicle-to-grid capabilities, will ultimately help make EV charging more convenient and ensure the electric grid can cleanly and reliably handle a significant uptick in electrified transport.
- Educate consumers: Utilities must ensure their customers are well-positioned to take advantage of EV benefits by educating them about how their charging behavior can impact the grid and the integration of renewable energy. More specifically, utilities must exercise load management via well-designed rates and other means in order to ensure their customers are charging their vehicles at times when renewables (rather than fossil fuels) are abundant and when the grid can best handle it. By reaching out to their customers through multiple means and languages, utilities can better ensure the robust participation needed in order to bring success.
- Emphasize vulnerable communities: Plans must genuinely consider benefits to and impacts on communities most likely to be harmed by pollution. Environmental Defense Fund (EDF) recommends a minimum percentage of charging stations be placed in these communities where applicable, and that all projects focus on enhancing transportation electrification in areas positioned to benefit them most.
Earlier this year, New York State committed to the purchase of two thousand electric vehicles by 2025, more than doubling its current fleet of government automobiles.
New York is also doing its share to expand electrification to make it easier for customers to buy and use electric vehicles. The State's Reforming the Energy Vision aims to align utility needs with marketplace innovations, and is doing the following:
- Decentralizing the electric grid so customers can make and buy renewable energy, New York is working toward a future where EVs and less pollution are commonplace.
- Developing favorable electricity rates to encourage charging of EVs at times when renewable energy is readily available and affordable. This way, EV adoption will benefit the grid and the environment.
Con Edison's Smart Charge NY program, an early stage effort in New York City, is paving the way for mainstream EV use; the results will be an example for how other cities can adopt the policies and tools necessary to seamlessly integrate EVs.
With more than 300,000 EVs and more than 12,000 charging stations, California leads the nation in clean car sales. Moreover, that number is poised to grow rapidly—California EV sales rose 91 percent in the first quarter of 2017 from the same time last year.
Even in the face of threats from the current U.S. Environmental Protection Agency head Scott Pruitt to take away California's waiver allowing the state to exceed national clean car standards, the Golden State has made clear its progress won't be stalled anytime soon. State legislators, cities and agencies have taken a tremendous amount of initiative on EVs, including:
- The California Air Resources Board has reaffirmed its commitment to maintaining stronger vehicle emissions standards.
- Volkswagen updated its plan for investing $800 million to accelerate electrified transportation in California, with input from the California Air Resources Board.
- Senate Bill 350 prioritizes widespread transportation electrification.
- In Los Angeles, half of all municipal vehicle purchases will be electric starting this year, and that share will increase to 80 percent by 2025. The city is also moving forward with a pilot EV ride share program to extend their benefits to communities with fewer car owners.
Moreover, as part of Senate Bill 350, investor-owned utilities filed applications with the California Public Utilities Commission for investments in light-duty, medium-duty and heavy-duty sectors.
The utility plans in particular represent an exciting new opportunity to accelerate electric transportation in all its forms. With planned projects from placing charging infrastructure for passenger EVs in single family homes, to providing car dealers with incentives and education to sell more EVs, to electrifying buses and ship ports—and everything in between—these plans are well-designed to clean the sector most responsible for harmful emissions.
Still, changes to the utility proposals would further strengthen them. EDF recommended to the California Public Utilities Commission that the plans focus more on load management as well as the other key elements listed above.
Despite obvious benefits, widespread EV adoption around the U.S. faces a number of challenges. For example, some analysts believe that even California will need another 200,000 charging stations to properly serve the number of EVs expected by 2030.
The internal combustion engine has had a long run, but it's about to burn out. As we work to address domestic barriers to EV adoption, it is important to note that even if it is a global effort, this is a race the U.S. may need to catch up on. As the electric vehicle market continues to flourish, EDF will continue to advocate and make sure environmental benefits follow financial rewards.
In 2010, world leaders agreed to 20 targets to protect Earth's biodiversity over the next decade. By 2020, none of them had been met. Now, the question is whether the world can do any better once new targets are set during the meeting of the UN Convention on Biodiversity in Kunming, China later this year.

- Your gut is home to trillions of bacteria that are vital for keeping you healthy.
- Some of these microbes help to regulate the immune system.
- New research, which has not yet been peer-reviewed, shows the presence of certain bacteria in the gut may reveal which people are more vulnerable to a more severe case of COVID-19.
You may not know it, but you have an army of microbes living inside of you that are essential for fighting off threats, including the virus that causes COVID-19.
How Do Resident Bacteria Keep You Healthy?<p>Our immune defense is part of a complex biological response against harmful pathogens, such as viruses or bacteria. However, because our bodies are inhabited by trillions of mostly beneficial bacteria, virus and fungi, activation of our immune response is tightly regulated to distinguish between harmful and helpful microbes.</p><p>Our bacteria are spectacular companions diligently helping prime our immune system defenses to combat infections. A seminal study found that mice treated with antibiotics that eliminate bacteria in the gut exhibited an impaired immune response.

Chronic Disease and Microbes<p>Patients with chronic illnesses including Type 2 diabetes, obesity and cardiovascular disease exhibit a hyperactive immune system that fails to recognize a harmless stimulus and is linked to an altered gut microbiome.</p><p>In these chronic diseases, the gut microbiome lacks bacteria that activate <a href="https://doi.org/10.1126/science.1198469" target="_blank" rel="noopener noreferrer">immune cells</a> that block the response against harmless bacteria in our guts.

That suggests that half of American adults carry a faulty microbiome army.</p><p>Research in my laboratory focuses on identifying gut bacteria that are critical for creating a balanced immune system, which fights life-threatening bacterial and viral infections, while tolerating the beneficial bacteria in and on us.</p><p>Given that diet affects the diversity of bacteria in the gut, <a href="https://www.umassmed.edu/nutrition/melody-trial-info/" target="_blank" rel="noopener noreferrer">my lab studies show how diet can be used</a> as a therapy for chronic diseases. Using different foods, people can shift their gut microbiome to one that boosts a healthy immune response.</p><p>A fraction of patients infected with SARS-CoV-2, the virus that causes COVID-19 disease, develop severe complications that require hospitalization in intensive care units. What do many of those patients have in common? <a href="https://www.cdc.gov/mmwr/volumes/69/wr/mm6912e2.htm" target="_blank" rel="noopener noreferrer">Old age</a> and chronic diet-related diseases like obesity, Type 2 diabetes and cardiovascular disease.</p><p><a href="http://doi.org/10.1016/j.jada.2008.12.019" target="_blank" rel="noopener noreferrer">Black and Latinx people are disproportionately affected by obesity, Type 2 diabetes and cardiovascular disease</a>, all of which are linked to poor nutrition.

Discovering Microbes That Predict COVID-19 Severity<p>The COVID-19 pandemic has inspired me to shift my research and explore the role of the gut microbiome in the overly aggressive immune response against SARS-CoV-2 infection.</p><p>My colleagues and I have hypothesized that critically ill SARS-CoV-2 patients with conditions like obesity, Type 2 diabetes and cardiovascular disease exhibit an altered gut microbiome that aggravates <a href="https://theconversation.com/exercise-may-help-reduce-risk-of-deadly-covid-19-complication-ards-136922" target="_blank" rel="noopener noreferrer">acute respiratory distress syndrome</a>.</p><p>Acute respiratory distress syndrome, a life-threatening lung injury, in SARS-CoV-2 patients is thought to develop from a <a href="http://doi.org/10.1016/j.cytogfr.2020.05.003" target="_blank" rel="noopener noreferrer">fatal overreaction of the immune response</a> called a <a href="https://theconversation.com/blocking-the-deadly-cytokine-storm-is-a-vital-weapon-for-treating-covid-19-137690" target="_blank" rel="noopener noreferrer">cytokine storm</a> <a href="http://doi.org/10.1016/S2213-2600(20)30216-2" target="_blank" rel="noopener noreferrer">that causes an uncontrolled flood</a> <a href="http://doi.org/10.1016/S2213-2600(20)30216-2" target="_blank" rel="noopener noreferrer">of immune cells into the lungs</a>.

However, identification of specific bacteria within the microbiome that could predict COVID-19 severity is lacking.</p><p>To address this question, my colleagues and I recruited COVID-19 hospitalized patients with severe and moderate symptoms. We collected stool and saliva samples to determine whether bacteria within the gut and oral microbiome could predict COVID-19 severity. The identification of microbiome markers that can predict the clinical outcomes of COVID-19 disease is key to help prioritize patients needing urgent treatment.</p><p><a href="https://doi.org/10.1101/2021.01.05.20249061" target="_blank" rel="noopener noreferrer">We demonstrated</a>, in a paper which has not yet been peer reviewed, that the composition of the gut microbiome is the strongest predictor of COVID-19 severity compared to patient's clinical characteristics commonly used to do so. Specifically, we identified that the presence of a bacterium in the stool – called <em>Enterococcus faecalis</em>– was a robust predictor of COVID-19 severity. Not surprisingly, <em>Enterococcus faecalis</em> has been associated with <a href="https://doi.org/10.1053/j.gastro.2011.05.035" target="_blank" rel="noopener noreferrer">chronic</a> <a href="https://doi.org/10.1016/S0002-9440(10)61172-8" target="_blank" rel="noopener noreferrer">inflammation</a>.</p><p><em>Enterococcus faecalis</em> collected from feces can be grown outside of the body in clinical laboratories. Thus, an <em>E. faecalis</em> test might be a cost-effective, rapid and relatively easy way to identify patients who are likely to require more supportive care and therapeutic interventions to improve their chances of survival.</p><p>But it is not yet clear from our research what is the contribution of the altered microbiome in the immune response to SARS-CoV-2 infection. A recent study has shown that <a href="https://doi.org/10.1101/2020.12.11.416180" target="_blank" rel="noopener noreferrer">SARS-CoV-2 infection triggers an imbalance in immune cells</a> called <a href="https://doi.org/10.1111/imr.12170" target="_blank" rel="noopener noreferrer">T regulatory cells that are critical to immune balance</a>.</p><p>Bacteria from the gut microbiome are responsible for the <a href="https://doi.org/10.7554/eLife.30916.001" target="_blank" rel="noopener noreferrer">proper activation</a> <a href="https://doi.org/10.1126/science.1198469" target="_blank" rel="noopener noreferrer">of those T-regulatory</a> <a href="https://doi.org/10.1038/nri.2016.36" target="_blank" rel="noopener noreferrer">cells</a>. Thus, researchers like me need to take repeated patient stool, saliva and blood samples over a longer time frame to learn how the altered microbiome observed in COVID-19 patients can modulate COVID-19 disease severity, perhaps by altering the development of the T-regulatory cells.</p><p>As a Latina scientist investigating interactions between diet, microbiome and immunity, I must stress the importance of better policies to improve access to healthy foods, which lead to a healthier microbiome. It is also important to design culturally sensitive dietary interventions for Black and Latinx communities. While a good-quality diet might not prevent SARS-CoV-2 infection, it can treat the underlying conditions related to its severity.</p><p><em><a href="https://theconversation.com/profiles/ana-maldonado-contreras-1152969" target="_blank">Ana Maldonado-Contreras</a> is an assistant professor of Microbiology and Physiological Systems at the University of Massachusetts Medical School.</em></p><p><em>Disclosure statement: Ana Maldonado-Contreras receives funding from The Helmsley Charitable Trust and her work has been supported by the American Gastroenterological Association.
