Electric vehicles are already considered as an environmentally conscientious alternative to traditional internal combustion engine vehicles, thanks to their zero tailpipe emissions. However, the environmental benefits of EVs can be further enhanced by implementing a home-base charging routine.

This is important not only for individuals looking to cut their household’s carbon footprint, but also for corporations that operate EV fleets and are looking for additional cost and environmental savings as part of their larger sustainability initiatives. What makes home charging the most eco-conscious option?

1. Increased use of renewable energy

More than 4 million homes in the United States support rooftop solar panels that provide renewable energy back to the property or back to the local grid. When EV owners install solar panels or other renewable energy systems at their homes, they can charge their vehicles using this clean energy, effectively reducing the carbon footprint associated with their EV use to nearly zero. This direct use of renewables circumvents the inefficiencies and emissions associated with the broader energy grid which, depending on the location, may still rely on fossil fuels to a significant extent. This synergy between EVs and clean local energy production is exemplified by Tesla’s solar roof program, which promotes the adoption of clean home-based energy production as part of the holistic EV ownership experience offered through their app.

2. Optimizing charging times for lower emissions

Home charging allows for more flexible and strategic charging schedules. EV owners can often take advantage of off-peak electricity rates and lower carbon intensity periods by charging their vehicles overnight or when renewable energy production (such as wind or solar power) is at its peak. This not only leads to cost savings for the consumer, but also contributes to a balanced demand on the electric grid, reducing the need for high-carbon emergency power sources that are sometimes activated during peak demand times. Apps like WhenToPlugIn use a carbon intensity forecasting tool to help consumers pick the best times to charge.

3. Reducing dependency on public charging infrastructure

Public charging stations are crucial for long-distance EV travel. For everyday use, the current public charging landscape is trailing the demand curve. The good news is that the majority of EV drivers can rely almost solely on home charging. This practice ensures public charging spots remain open for those who, due to circumstances such as residing in multi-unit dwellings without charging facilities, cannot charge at home. Consequently, this accessibility supports wider adoption of EVs, leading to a more substantial reduction in overall emissions.

4. Avoiding unnecessary travel to public charging stations

The average driver has to detour 2 miles to refill their gas tank. For electric vehicles, finding an available public charger can add many more miles to a trip. Home charging ensures that EVs can start each day with a “full tank” — which, with new EVs, means hundreds of miles of range before needing to plug in again. This reduction in driven miles not only saves time but also decreases the energy consumption and emissions associated with traveling to and from charging stations unnecessarily. By charging at home, EV owners can ensure their vehicles are ready to go without extra trips, further cutting down on the vehicle's overall environmental impact.

5. Enhancing battery longevity

Charging at home typically involves slower charging speeds compared to rapid chargers found in public stations. These slower, more controlled charging rates are less taxing on an EV's battery, contributing to longer battery life and better overall efficiency. Longer battery lifespans mean fewer replacements over the vehicle's life, significantly reducing the environmental impact associated with battery production and disposal. This not only has clear environmental benefits but also economic ones for the vehicle owner.

Conclusion

The environmental benefits of electric vehicles are well-documented, but by incorporating home charging, these benefits are amplified significantly. Through the increased use of renewable energy, optimizing charging times to utilize green power, and reducing reliance on public charging infrastructure, EV owners can further reduce their environmental footprint. As technology advances and the energy grid becomes cleaner, the potential for home charging to contribute to a more sustainable future only grows, reinforcing the role of electric vehicles in the transition to greener transportation options.

Guest column: Cold weather and electric vehicles — separating fact from fiction

EVs in winter

Winter range loss is fueling this season’s heated debate around the viability of electric vehicles, but some important context is needed. Gasoline cars, just like their electric counterparts, lose a significant amount of range in cold weather too.

According to the Department of Energy, the average internal combustion engine’s fuel economy is 15 percent lower at 20° Fahrenheit than it would be at 77° Fahrenheit, and can drop as much as 24 percent for short drives.

As the world grapples with the implications of climate change and shifts toward sustainable technologies, it's important to put the pros and cons of EVs and traditional gas vehicles in perspective. And while Houston isn't known as the coldest of climates, you still might want to review this information.

The Semantics of Energy Consumption Hide the Real Issue: Cost

First, let's talk about the language. When discussing gas vehicles in cold climates, the conversation often centers around "fuel efficiency." It sounds less threatening, doesn't it? But in reality, this is just a euphemism for range loss, something for which EVs are frequently criticized.

Why does that matter? Because for most drivers who travel less than 40 miles a day, what range loss really means is higher fueling costs. When a gas vehicle loses range, it costs a lot more than the same range loss in an EV. For example, at $3.50 a gallon, a car that gets 30 MPG in warm weather and costs $46.67 to go 400 miles suddenly costs $8.24 more to drive the same distance. By contrast, an EV plugging in at $0.13 per kWh usually costs $13 to go 400 miles and bumps up to a piddly $16.25 even if it loses 20 percent efficiency when the temperature drops.

Some EV models lose 40 percent in extreme cold. OK, tack on another $3. That still leaves almost $30 in the driver’s pocket. Over the course of a year, those savings pile up.

Let’s Call It What It Is: Fear Mongering

Any seismic shift in technology comes with consumer hesitancy and media skepticism. Remember when everyone was afraid to stand in front of microwaves and thought the waves would make the food unsafe to eat? Or how, just a decade or so back everyone was talking about how cell phones could spontaneously explode?

Fear of new technology is a natural psychological response and to be expected. But it takes the media machine to turn consumer hesitation into a frenzy. Any way you slice it, 2023 was one big platform for expressing fears around EVs. Headline-grabbing tales of EV woes often lacked context or understanding of the technology. In a highly partisan landscape where EVs have been dubbed liberal leftist technology, what should be seen as a miraculous pro-American, pro-clean-air, pro-energy independence, pro-cost saving advancement is getting a beating in the press. In this environment, every bit of “bad EV news” spirals out into an echo-chamber of confirmation bias.

For example, Tesla’s recent software update was hyped as a 2 million vehicle “recall” even though the software was updated over the air without a single car needing to leave the driveway. Hertz's recent decision to reduce its Tesla fleet was seen by many as a referendum on the cars’ quality but was actually a decision based on Hertz’s miscalculations around repair costs and a mismatch in their projections of consumer demand for EV rentals.

While the cost of repairs might be higher, maintenance and fuel costs are still much lower than gas vehicles. EVs are better daily-use cars than rentals because while our country’s public charging infrastructure is still lagging, home charging is a huge benefit of EV ownership. Instead, the Hertz move and the negative coverage are further spooking the public.

The Truth About EVs

Despite the challenges, it's crucial to acknowledge the environmental advantages of EVs. For instance, EVs produce zero direct emissions, which significantly reduces air pollution and greenhouse gasses. According to the U.S. Environmental Protection Agency, EVs are far more energy efficient than gas-powered cars, converting more than 77 percent of electrical energy from the grid to power, compared to 12-30 percent for gasoline vehicles.

This efficiency translates to a cleaner, more sustainable mode of transportation. And stories of EVs stranded in Chicago aside, generally they perform well in cold weather, as clearly demonstrated in Norway. In Norway, the average temperature hovers a solid 10 degrees lower than in the U.S. Yet 93 percent of new cars sold there are electric. The first-ever drive from the north to the south pole was also completed by an electric vehicle. The success story of EVs in Norway and demonstration projects in harsh winter climates serve as a powerful counterargument to the notion that EVs are ineffective in cold weather.

So where does this leave us? The discourse around EVs and gasoline vehicles in cold weather needs a more balanced and factual approach. The range loss in gasoline vehicles is a significant issue that mirrors the challenges faced by EVs. By acknowledging this and understanding the broader context, we can have a more informed and equitable discussion about the future of automotive technology and its impact on our environment.

Here's a closer look at why Houston should be pushing for a more rapid transition to EVs. Photo via Getty Images

5 reasons Houston should prioritize electric vehicle adoption in 2024

guest column

As urban populations increase and more vehicles hit the roads across the United States, the quality of the air is compromised, directly impacting health, environment, and quality of life ― especially for children, minorities, and other vulnerable populations. A 2023 study by Site Selection Group placed Houston at the vanguard of this trend, projecting the metro area to grow nearly 10 percent by 2028, eclipsing 8 million residents.

According to Evolve Houston, a nonprofit working to accelerate EV adoption by bringing together local public and private organizations, residents, and government, the transportation sector emits 47 percent of all greenhouse gas emissions in the Houston area.

In this context, electric vehicles offer a practical solution to mitigate the challenges posed by tailpipe emissions. Their adoption in urban settings has the potential to significantly improve air quality and enhance public health. It’s no wonder the upcoming Houston Auto Show will feature a dedicated EV Pavilion.

Here's a closer look at why Houston should be pushing for a more rapid transition to EVs:

  1. Children’s development is at stake: Early childhood is a critical period for brain development. However, toxic air pollutants can significantly inhibit this growth during these formative years. The consequences include impairing children’s cognitive capabilities in reading and math, akin to missing an entire month of elementary school.
  2. EVs counteract historical racial inequalities: Beyond being an environmental challenge, air pollution is a glaring racial and social justice issue. Areas with fewer White residents suffer almost triple the nitrogen dioxide levels compared to predominantly White zones, as highlighted by the National Academy of Sciences. Historically marginalized communities, often near major traffic corridors, endure heightened pollution exposure. Transitioning to EVs can help address these deeply ingrained environmental inequities.
  3. The health benefits are monumental: A brighter future awaits if EVs become mainstream. According to the American Lung Association, if all new vehicles sold by 2035 are zero-emission, the U.S. could see up to 89,300 fewer premature deaths by 2050. Additionally, asthma attacks might decline by 2 million, saving 10.7 million workdays and resulting in an incredible $978 billion in public health savings.
  4. Global success stories prove the benefits: The impact of mass EV adoption has already been demonstrated outside the U.S. For instance, Norway has seen a notable reduction in dangerous particle emissions since 87 percent of its new car sales are now fully electric. Likewise, California’s adoption of electric vehicles correlated with a 3.2% decrease in asthma-related ER visits between 2013 and 2019.
  5. Cities have the power and means to lead the way: Many global cities are trailblazers in the electric transition. New York City, with more than 4,000 government-owned EVs, is a prime example. Moreover, by electrifying their take-home fleets, cities can set a precedent for their communities. Seeing neighbors drive electric vehicles daily serves as a powerful endorsement, motivating nearby residents to make the switch. Incentives like public charging stations, free parking for EVs, rebates for home charger installations, reimbursing for charging at home, and reduced tolls, further bolster this movement.

Houstonians stand at a pivotal juncture. The choices made today concerning transportation will profoundly influence the health and well-being of residents tomorrow. The shift to electric vehicles is more than just an eco-friendly choice; it's a commitment to a brighter, cleaner future. By leading with action and vision, cities can create a legacy that upcoming generations will appreciate and thrive in.

Texas-based Tesla gets China's initial approval of self-driving software

global greenlight

Shares of Tesla stock rallied Monday after the electric vehicle maker's CEO, Elon Musk, paid a surprise visit to Beijing over the weekend and reportedly won tentative approval for its driving software.

Musk met with a senior government official in the Chinese capital Sunday, just as the nation’s carmakers are showing off their latest electric vehicle models at the Beijing auto show.

According to The Wall Street Journal, which cited anonymous sources familiar with the matter, Chinese officials told Tesla that Beijing has tentatively approved the automaker's plan to launch its “Full Self-Driving,” or FSD, software feature in the country.

Although it's called FSD, the software still requires human supervision. On Friday the U.S. government’s auto safety agency said it is investigating whether last year’s recall of Tesla’s Autopilot driving system did enough to make sure drivers pay attention to the road. Tesla has reported 20 more crashes involving Autopilot since the recall, according to the National Highway Traffic Safety Administration.

In afternoon trading, shares in Tesla Inc., which is based in Austin, Texas, surged to end Monday up more than 15% — its biggest one-day jump since February 2020. For the year to date, shares are still down 22%.

Tesla has been contending with its stock slide and slowing production. Last week, the company said its first-quarter net income plunged by more than half, but it touted a newer, cheaper car and a fully autonomous robotaxi as catalysts for future growth.

Wedbush analyst Dan Ives called the news about the Chinese approval a “home run” for Tesla and maintained his “Outperform” rating on the stock.

“We note Tesla has stored all data collected by its Chinese fleet in Shanghai since 2021 as required by regulators in Beijing,” Ives wrote in a note to investors. “If Musk is able to obtain approval from Beijing to transfer data collected in China abroad this would be pivotal around the acceleration of training its algorithms for its autonomous technology globally.”
