Electric vehicles are gaining ground in Nevada, with new cheaper models and federal incentives enticing drivers away from gasoline-dependent transportation.

The U.S. Environmental Protection Agency is expected to soon issue updated pollution limits for new passenger cars and trucks that could slash billions of tons of planet-warming carbon dioxide pollution. 

And in Nevada, the push for widespread electric-car adoption by President Joe Biden could also be a boon for the state economy. 

EV advocates at a press conference Wednesday highlighted how electrification has created high-paying union jobs and billions in infrastructure investments.

Nevada has pulled in $15 billion in private investment in electric vehicle and battery production, creating more than 12,000 jobs, according to a recent analysis by the Environmental Defense Fund, an environmental advocacy group.

Nevada ranks fifth in the country for new investments in electric vehicle and battery manufacturing, according to the Environmental Defense Fund. The state also ranks fifth in terms of electric vehicle adoption per 1,000 vehicles, with about 45,000 registered electric cars on the road.

Investments in infrastructure for electric vehicles have been spurred by $27 billion in federal, states, and local investments nationally.

The International Brotherhood of Electrical Workers Local 1245 in Nevada has trained thousands of union workers to meet those new demands of electric vehicle infrastructure. Hunter Stern, assistant business manager of IBEW Local 1245, said large investments in charging stations in the state have already resulted in good-paying union jobs for Nevada residents.

In 2021, the Nevada Legislature passed a mandate requiring NV Energy to implement a plan to expand infrastructure for charging stations. The utility invested $100 million in an effort to build nearly two thousand electric vehicle chargers over three years.

“That’s now jobs for IBEW members,” Stern said, during the press conference at the Las Vegas Convention Center. “We hope to install more and more charging stations at facilities like the convention center. We’ve gotten charging stations in many of the casinos and hotels here in Las Vegas, and in Reno and Sparks, but we want more.”

A recent analysis by the International Council on Clean Transportation found that the growth of charging infrastructure could create more than 160,000 jobs by 2032, while about 50% of those jobs will be electrical installation, maintenance and repair jobs.

“Those numbers are going to be skewed higher here in Nevada because of the commitment the state has already made, the plans that are being made, and the work that is coming,” Stern said.

Stern said IBEW Local 1245 in Nevada has trained more than 1,000 workers in the state to work on transportation electrification and has increased the training capacity at facilities in the state to train enough workers to meet demand. 

“The state adopted an aggressive, IBEW-endorsed EV charging infrastructure plan that has already met several of its targets. We are meeting the moment,” Stern continued.

Nevada is also on track to receive $38 million from the National Electric Vehicle Infrastructure (NEVI) program, funding that will pay for even more charging stations in the state.

Clark County Commissioner William McCurdy highlighted the county’s plan to achieve net zero emissions by 2050, a goal that will require electric vehicle buy-in, said McCurdy.

“It’s our job as elected officials to address extreme heat and attain air quality standards. Nearly a third of greenhouse gas pollution comes from the transportation sector, and zero emission clean cars will protect the health of Las Vegas and help clean our air,” McCurdy said.

“We’re doing everything we can to improve our electric vehicle infrastructure,” he continued.

Electric vehicles are also becoming more affordable in Nevada, according to the International Council on Clean Transportation.

There are 37 EV models available in Nevada for less than the average new vehicle purchase price of $48,000, with 12 models available for less than $35,000, said David Kieve, president of Environmental Defense Fund Action, the political arm of the group. On average, Nevadans can save up to $27,900 on an electric vehicle compared to a gas-powered vehicle over 10 years, according to the group’s analysis.

Americans are being incentivized more than ever to purchase elective vehicles. Electric vehicle owners can receive as much as a $7,500 federal tax rebate on a new EV or $4,000 for a used one.

“If you’re not sure whether your next car, truck, or SUV should be electric, just ask one of the 45,000 people in the state who own them. Ask them whether they miss spending their hard-earned money at the gas pump, or on costly repairs,” Kieve said.

To understand the stakes of cleaning up the most-polluting vehicles on our roads, look no further than Charlotte.

The largest city in North Carolina, it’s at the crossroads of two major trucking routes, with 17,000 trips per day spewing smog- and soot-forming pollutants that consistently rank the metro area among the nation’s 100 worst for air quality.

It’s also a burgeoning epicenter for electric vehicle manufacturing and research, home to many of the state’s 40-plus businesses that are already playing a role in the medium- and heavy-duty electric vehicle supply chain.

Clean transportation advocates say the air quality and economy in Charlotte and throughout the state stand to benefit from new Biden administration tailpipe emission rules for heavy-duty trucks, which account for an outsized share of the region’s climate emissions and air pollution.

“The Heavy Duty Rules are a critical step forward in establishing a ‘federal floor’ for clean trucks all across the country,” said Aaron Viles, campaigns director with the Electrification Coalition.

But they also say there’s still a need for other policies to usher in a new generation of electric trucks and buses, including a state-based rule scuttled by the GOP-controlled legislature last year. 

Among the leaders? 

The transportation sector is the largest source of global warming pollution and the country. Cleaning it up, experts say, means phasing in new electric vehicles of all shapes and sizes, reducing our use of passenger vehicles overall, and powering the grid with renewable energy. 

The transition is not without hurdles. Would-be electric vehicle owners and fleet managers worry about a lack of charging infrastructure. And while the costs of electric-powered vehicles are falling steadily and the price of operating them is minimal, potential consumers still balk at their relatively high sticker price.

What’s more, many of the vested interests that revolve around gas and diesel vehicles prefer the status quo, and they extend well beyond the oil industry — including dealers who make money from oil changes and other routine repairs, fueling stations, and manufacturers of engine components.

But climate advocates say overcoming these obstacles has rewards beyond just reducing greenhouse gasses and avoiding catastrophic global warming. In North Carolina, that’s especially true when it comes to cleaning up heavy duty vehicles.

Though trucks, buses and the like make up a tiny fraction of all vehicles on the road, they account for over a quarter of the North Carolina transportation sector’s smog-forming pollutants and nearly a third of its soot-forming emissions, per state officials. Zero-emission vehicles would help curb this pollution.

The transition to heavy-duty electric vehicles could also benefit North Carolina’s economy, with dozens of industries across the state already invested in component production, assembly, or other aspects of the supply chain, according to a 2021 database compiled by the Environmental Defense Fund.

“When you look at where the electric vehicle supply chain investments are going, it’s really clustered in a number of leading states,” said Will Scott, Southeast climate and clean energy director with Environmental Defense Fund. “And North Carolina is among those.”

State v. federal action 

Gov. Roy Cooper, a Democrat who is term-limited after this year, had sought first to garner these benefits with the Advanced Clean Truck rule. Initiated with an October 2022 executive order, the measure requires manufacturers to sell increasing numbers of electric trucks, buses, and other large vehicles. California pioneered the standard, and it has been adopted by 10 other states.

But after prodding from the North Carolina Chamber, Republicans who control the General Assembly balked, passing a provision in the state budget to prevent the rule.  

“Government mandates and intervention into the market would stifle… innovation and investment,” the Chamber wrote on its website after the budget language prevailed, “as well as increase costs in new trucks, on which nearly all of our members rely.” 

The new U.S. Environmental Protection Agency measure, issued this spring, is less ambitious than the California one. But with the Advanced Clean Truck rule essentially dead in the state, advocates say the federal regulation is welcome. 

“States that don’t have ACT will now have a federal policy that can support cleaning up our medium- and heavy-duty transportation sectors,” said Stan Cross, transportation director for Southern Alliance for Clean Energy.

In an effort to mollify the industry, Biden officials made their rule “technology neutral,” meaning it would require manufacturers meet a certain tailpipe pollution limit rather than sell a certain percentage of electric vehicles. 

The Electrification Coalition says that means the federal rule will result in lower overall electric sales for most classes of vehicles. For instance, the Biden rule is expected to result in as little as 5% of new tractor cab sales bring electric by 2032, depending on class on weight. The California standard, by contrast, requires 40% of all heavy-duty tractor sales to be zero-emitting – and most likely electric, though other technologies qualify.

Still, when it comes to less air and global warming pollution, cleaning up trucks and buses nationwide has an obvious advantage over a patchwork of states doing so. Overall, the Biden administration expects its rule to avoid 1 billion tons of greenhouse gasses.

There’s also value in Biden attacking transportation sector pollution nationally, piece by piece, Cross said. The administration has already promulgated similar rules for passenger cars and trucks, and standards for port equipment, off-road vehicles, and more are still forthcoming.

“They’re doing the math, and they’re thinking about these standards in a comprehensive and holistic way,” said Cross. “They can look at all of our ports, all of our marine traffic, all of our airports, all of our plane traffic, all of our off-road construction — and set standards that will get us where we need to be.”

In a state like North Carolina, home to several major interstates and their truck traffic, cleaning up trucks beyond state borders will also help reduce health-threatening air pollution. An American Lung Association analysis of states with major trucking routes, for example, found that if all heavy-duty vehicle sales were electric by 2040, the state could avoid over 1,700 premature deaths and hundreds of thousands of lost work days.

Those benefits would be crucial for Charlotte, which consistently ranks among the 100 most polluted cities in America for smog-and soot-forming pollution in the Lung Association’s annual State of the Air report.

“Charlotte advocates for clean air, which includes using electric transportation,” Charlotte Mayor Vi Lyles said in a written statement praising the new rules.

And for North Carolina businesses in the medium- and heavy-duty electric vehicle supply chain, the prospect of a national market is clearly better than customers in a smattering of states.

Anything that accelerates the trend toward electric vehicles, Scott said, will come back to the state in the form of jobs and economic activity.

“North Carolina has put itself in a good position to capture a lot of those benefits,” he said.

‘Pole position’ 

Still, the nationwide rule has a major downside for fleet managers from North Carolina cities and corporations that have commitments to go all-electric. The supply of heavy-duty electric vehicles is still relatively low, and the states who have adopted the Advanced Clean Trucks Rule will get first dibs on it.  

The problem could be especially acute in the near term, during which manufacturers can satisfy national requirements just by catering to the 11 states with the more advanced rule.  

“ACT puts your state in pole position for the limited amount of zero-emission, trucks and buses that are going to be coming off of assembly lines,” Cross said. 

Indeed, that’s part of why advocates supporting the federal standard say they’ll keep looking for opportunities to pass the Advanced Clean Truck Rule in the state.  

And though it has little chance of passage, Cooper’s budget this year removes last year’s prohibition on the stronger clean truck standard and includes funding for electric vehicle infrastructure. 

“We applaud the governor for taking these steps to end oil’s monopoly on our transportation systems,” said Anne Blair, the Electrification Coalition’s vice president of policy. “But there is still much more that needs to be done to ensure North Carolina and the country are not left behind as the world shifts to electric transportation.”

After setbacks to adopting electric vehicle sales targets in Maine and Connecticut, New England clean transportation advocates are regrouping with a focus on charging infrastructure and consumer education. 

Maine’s Board of Environmental Protection voted 4-2 on March 20 against adopting California’s Advanced Clean Cars II rules, which would have required electric or plug-in hybrids to make up 82% of new vehicle sales in the state by model year 2032.

Board members initially signaled support for the proposal, which came from a citizen petition last spring, before their first planned vote was delayed by a severe storm in December. 

Last November, Connecticut Gov. Ned Lamont, a Democrat, pulled a comparable proposal from legislative consideration after it was not expected to have the votes to pass.

Neither state had opted to consider California’s Advanced Clean Trucks standard, which sets similar targets for heavy-duty vehicle sales. 

Maine and Connecticut are among more than a dozen states that have had earlier versions of California’s clean car standards on the books for years. Both states have also prioritized transportation emissions, the region’s biggest contributor to global warming, in their climate plans. 

Some advocates fear progress in this sector will stall in these states until they adopt the updated California rules. They say debate over the standards was clouded by false and misleading claims, often pushed by fossil fuel industry groups, that have ramped up as part of the 2024 presidential campaign. 

“It was really an attempt to confuse and agitate consumers, and unfortunately it was successful,” said Charles Rothenberger, the climate and energy attorney at the Connecticut nonprofit Save the Sound. 

Fear of ‘losing ground’

Even if Connecticut or Maine successfully revisits adopting the California rules next year, it would likely push implementation out to model year 2029 at the earliest, advocates said. 

States that don’t use the new California standards will default to federal rules for reducing vehicle emissions. These rules were just overhauled but have a slower timeline than California’s, designed to accommodate states with lower EV sales rates than in much of New England, Rothenberger said.

“Standards that really cater to the laggards when it comes to EV adoption are really not beneficial to states that are well ahead of that curve,” he said. “I fear that it will lead to us losing ground to states that continue with the California standards,” such as Massachusetts and New York, Rothenberger added. 

This could mean less choice and supply for both new and used electric vehicles as carmakers focus on those other states, he said. 

In the meantime, Connecticut EV advocates are backing a bill in the General Assembly to allow state bonds for charging infrastructure and EV incentives and create an Electric Vehicle Infrastructure Coordinating Council to work with utility regulators on system planning, among other provisions. 

Peter LaFond, the Maine program director for the Acadia Center, a regional nonprofit, said the delay in adopting California’s rules provides time for combating misconceptions and for utilizing increasing state and federal funds for charging infrastructure. 

“Every month that goes by, I think there’ll be more and more chargers, and once there are, I think people will see the clear advantages,” LaFond said. “(EVs and plug-in hybrids) lower the carbon footprint and they’re less expensive to operate, and the cold doesn’t present as much of a challenge as the misinformation would have you believe. I think education is going to be a big part of this.” 

A snowball effect in rural areas

Scott Vlaun, the executive director of the Center for an Ecology-Based Economy, a nonprofit in the small western Maine town of Norway, said he sees a snowball effect of EV acceptance in his region.

“It’s happening, it’s just not happening fast enough,” Vlaun said. “This is the future, and if Maine doesn’t get its share, then … we’re going to be kind of stuck — in, especially rural Maine — with people driving beat-up, old, inefficient cars, and it’s not good for anybody.” 

CEBE has led a push for a large public EV charger network in and around Norway, which Vlaun said has helped make EVs and hybrids a more common sight everywhere from Main Street to nearby ski resorts. 

“We do this annual EV expo, and if you get people driving an F-150 Lightning, or a Chevy Bolt, depending on what their needs are, they get it,” he said. “So much of the misinformation — it’s almost comical, because it’s obvious that these people have never gotten behind the wheel of an electric car.” 

Vlaun was speaking from his own EV parked at a public charger outside CEBE’s office, having just driven back from a meeting in Portland, Maine, about an hour away. He said he would have liked to take a train or bus instead of driving, but doesn’t have an easy option for doing so. 

“We don’t see electric cars as a one-to-one replacement for gas cars,” he said. “We see electric vehicles as an interim step and a better solution to individual transportation than gas-powered vehicles — not the answer to the world’s transportation problems by any stretch.” 

Advocates in Connecticut agreed that encouraging cleaner public transit, more walkable cities and less driving overall is as much or more important to reducing transportation emissions as EV adoption. 

Community health impacts

Those emissions are linked to disproportionate asthma rates, low school test scores and other adverse public health ripple effects in Connecticut, said Dr. Mark Mitchell, the co-chair of the Connecticut Equity and Environmental Justice Advisory Council. 

“The people who have the least ability to afford cars and to drive suffer the most from the pollution caused by cars, and so we need to change that — we need to invest in public transportation and making cities walkable and bikeable,” he said. “We’re not going to get rid of cars… but we should make sure that the cars that drive through our communities are as clean as possible, as quickly as possible.” 

Mitchell said he lives in an especially low-income part of Hartford, the state capital — one of the lowest-income cities on the East Coast, with a mostly Black and Latino population. Mitchell said many of his neighbors don’t drive at all and can’t afford new cars, so they don’t yet “see themselves in EVs.” 

“But that’s not the point,” he said. “The point is that they’re very concerned about asthma, they’re very concerned about ADHD, they’re very concerned about school test scores.”

EV adoption across the state is one solution to those problems, he said.  

Jayson Velazquez, the Acadia Center’s Hartford-based climate and energy justice policy associate, used the term “through-emissions” to describe pollution from diesel trucks and other vehicles that traverse low-income neighborhoods and communities of color in Connecticut’s cities en route to nearby highways. 

Unlike those vehicles and their non-local drivers, Velazquez said, “the lasting health effects that come from that pollution don’t just get up and go.” 

Despite concerns about misinformation, advocates acknowledged that they share certain concerns with opponents of the California rules — such as affordability, charging access, the sustainability of minerals mining to build batteries, and strain on the power grid from increasing EV use. 

“There are real issues,” said Mitchell. “We do need to build up the infrastructure, both the charging infrastructure and the electric grid. … But until we set goals, we don’t know how quickly we need to do that. And it’s much easier to put things off if you don’t have a goal.”

One of California’s marquee programs for cleaning up transportation emissions is at a crossroads. Decisions made in the next few months could set the decade-and-a-half-old Low Carbon Fuel Standard on one of two very different paths.

One path, favored by fossil fuel and renewable natural gas interests, would lock in a market scheme that currently extracts billions of dollars per year from Californians at the pump and subsidizes crop-based and cow-manure-derived biofuels.

That would be a disaster, according to environmental advocates, who point to a growing body of scientific evidence showing that this approach, if extended until 2045 as proposed, would cause these biofuels to grow at a scale that would harm the climate and the environment.

The other path, proposed by environmental groups, transportation-decarbonization analysts and climate and energy researchers, would limit the scope of unsustainable biofuels in the program, and instead reorient it to support what experts agree should be California’s primary clean transportation pathway: electric vehicles.

To date, roughly 80 percent of LCFS funding has gone to combustion biofuels rather than electric vehicles. That’s simply incompatible with the state’s EV ambitions and needs, said Adrian Martinez, deputy managing attorney of nonprofit advocacy group Earthjustice — and the imperative to reduce emissions from transportation, which account for nearly 40 percent of the state’s greenhouse gas emissions.

“We’ve got to eliminate our reliance on combustion,” he said, but ​“the program as designed will continue to provide lucrative incentives for combustible fuels well into the future.”

The regulator in charge of the LCFS program — and this high-stakes decision — is the California Air Resources Board. CARB’s board, which comprises 14 voting members, 12 appointed by the governor and two by the state legislature, holds a host of responsibilities around California’s energy transition. Those include shaping the state’s nation-leading EV policy, as well as determining its broad plans for achieving long-term greenhouse-gas reduction goals.

Critics say the LCFS program’s increasing support for biofuels is in direct contrast to both the EV targets and the climate goals also overseen by CARB — and that the program has been captured by deep-pocketed industries trying to greenwash the continued use of combustion fuels.

CARB has a chance to reform the program with an upcoming vote, initially set for this month, but now postponed to an undetermined future date. But its pathway to fixing the problems that plague LCFS is murky and messy at best.

Right now, the staff managing the LCFS program hasn’t given CARB board members an opportunity to pick a climate- and EV-friendly alternative. Instead, a December staff proposal provides only one option for the board to vote on later this year: a set of policies that Earthjustice forecasts would direct $27 billion over the coming decade toward biofuels and worsen effects on the climate, the environment and the prices that Californians pay at the pump.

CARB does have another option, however — an alternative proposal laid out by CARB’s Environmental Justice Advisory Committee, created to advise the board on environmental-justice issues.

That proposal would cap the fast-growing share of crop-based renewable diesel flooding the state. It would also end the unusual structure that now allows biogas produced by dairy farm manure to offset a much higher amount of carbon emissions than any other source of alternative fuels.

And, importantly, it would make the core of the program — its carbon-offset marketplace — function in a much healthier way, proponents say. A torrent of cheap, polluting renewable diesel and dairy farm biogas credits have dragged down the price that LCFS credits can fetch for avoiding emissions, diluting the incentive to deploy new climate technologies and sapping what could be a key funding source for EV infrastructure in the state.

“The stakes are very, very high,” Martinez said. ​“That’s why you see so much attention focused on this — and a very broad and diverse coalition that is pushing for more systemic change to the program, versus more modest tweaks that will really just keep this market owned and dominated by fossil fuel interests.”

A history of the LCFS program

California’s Low Carbon Fuel Standard was born out of AB 32, the 2006 law that created the state’s carbon cap-and-trade market. Much like carbon markets, LCFS is meant to make companies pay for their carbon emissions by buying credits from technologies that reduce carbon emissions.

The program requires all fossil fuels refined and sold in California to meet increasingly stringent carbon-intensity targets. In practice, fossil fuel producers have to buy a bunch of LCFS credits from low-carbon transit sources operating in the state in order to comply. The goal is to create a system that taxes planet-warming fossil fuels to fund cleaner transportation alternatives.

But the LCFS has strayed from its initial focus on vehicle electrification and ​“advanced” non-crop-based biofuels to become ​“a swag bag for venture capitalists, big oil, big agriculture, and big gas, increasingly coming at the expense of low- and moderate-income Californians.” That’s how Jim Duffy, a 13-year veteran of the agency who served as branch chief of the LCFS program from 2019 to 2020 and retired in 2022, described the evolution of the program in comments filed with CARB.

Under the LCFS regulation adopted in 2009, dairy-manure-to-biogas projects did not receive special treatment compared to other sources of methane such as landfills and sewage treatment plants, Duffy wrote. Similarly, diesel fuels made from crops like soybeans were considered ​“only marginally better than fossil diesel.”

But in the years since, ​“the LCFS was revised to provide additional and unnecessary support to landfills and first-generation crop-based biofuels” and ​“to mitigate the methane problem created by the dairy industry itself,” Duffy wrote — despite the fact that evidence increasingly suggests that both sources harm the planet far more than they benefit it.

The result has been an increasing share of LCFS credits being supplied by renewable diesel and dairy-generated biogas. 

CARB has justified these shifts with analysis indicating they will yield net positive climate impacts.

“The proposed amendments now under consideration will directly increase the program benefits in the most burdened communities, by reducing the carbon across the supply chain for fuels sold in California, as well as improving public health for fuels sold in California,” CARB spokesperson Dave Clegern said in an email to Canary Media. He cited data from CARB staff’s analysis of its proposal indicating that, by 2045, its plan will reduce nitrogen oxide emissions by 25,586 tons, cut greenhouse gas emissions by 560 million metric tons and yield public-health cost savings of nearly $5 billion. 

But critics say the agency is failing to account for the full scope of climate harms that will be caused by its continued emphasis on biofuels.

They warn that the sheer scale of California’s program — totaling some $4 billion per year — is driving investment in the wrong transportation alternatives. The consequences are dire, they say — not just within the state, but across the country and around the world.

Why renewable diesel is threatening CARB’s climate and credit goals

Take renewable diesel, a fuel made from fats and oils processed to be identical to fossil diesel fuel. The U.S. increased production of the fuel by 400% between 2019 and 2022, and it is set to double it again this year, according to Jeremy Martin, senior scientist and director of fuels policy for the Union of Concerned Scientists.

Unlike ethanol and biodiesel, which can only partially replace gasoline and diesel, renewable diesel has ​“no limit on how much can be blended,” Martin said. It could theoretically completely replace diesel fuel for trucks, buses and other vehicles. And California’s LCFS offers credits on top of the federal incentives the fuel receives, making the state the primary target of renewable diesel producers across the country.

As a result, the share of renewable diesel as a percentage of total diesel fuel use has skyrocketed in California compared to the rest of the U.S., as the chart below shows.

In a September meeting, Steven Cliff, CARB’s executive officer, highlighted a milestone for the LCFS program: As of mid-2023, California had ​“more than half of our diesel demand being met by non-petroleum-based diesel alternatives. This is a direct result of the LCFS program, and it’s bringing real climate and air-quality benefits to the state.”

In Martin’s view, that milestone is not a win, but a warning. It indicates that renewable diesel is ​“flooding the LCFS, drowning the policy — and it doesn’t make sense” on climate or environmental terms.

Once the demand for renewable diesel outgrows the supply of waste oils and other non-crop feedstocks that can be used to make the fuel in genuinely climate-friendly ways, it becomes highly likely that it will cause more greenhouse gas emissions than it will displace. Critics like Martin argue that demand has now reached this point, though it’s a contested question.

This additional demand for crop oils could mostly serve ​“to expand the cultivation of palm oil to replace the soybean and other oils made into fuel,” the Union of Concerned Scientists argued in comments to CARB. That, in turn, is likely to lead to more rapid deforestation in nations that produce large amounts of these crops, such as Brazil and Indonesia — an outcome that would cause far greater climate harms than whatever emissions reductions result from replacing fossil diesel.

To stop this, the Union of Concerned Scientists and other groups want CARB to set a limit on how much renewable diesel can receive LCFS credits. CARB staff’s proposal declines to set such a cap, citing renewable diesel’s climate and health benefits.

But CARB’s methodology is out of step with the latest science, according to multiple groups studying these issues. The Union of Concerned Scientists, for its part, says CARB’s analysis is ​“based on inaccurate claims of climate and air-quality benefits and associated health outcomes.”

In a recent comparison of five different models for evaluating the climate impacts of crop-based biofuels, the U.S. Environmental Protection Agency found that only CARB’s own model shows a positive carbon-reduction impact.

And while the agency has a proposal to limit deforestation harms by setting ​“sustainability guidelines” for crops being used for renewable diesel, it applies only to feedstocks grown in the U.S., Martin noted. That’s a problem: California is on pace to consume 10 percent of global soybean oil supplies for renewable diesel, meaning a significant amount of the crop oil produced for the program will be grown under conditions CARB cannot police, he said.

Given that reality, Martin said, ​“If California declines to act — if they say, ​‘This is evidence of success; look how little fossil diesel we’re using’” by replacing it with renewable diesel, ​“then, in fact, California is giving its support to a fuel that we know is unsustainable at these volumes.”

As a historic 10-day heat wave threatened brownouts across California last summer, a small San Diego County school district did its part to help: It captured excess power from its electric school buses and sent it back to the state’s overwhelmed grid.

The eight school buses provided enough power for 452 homes each day of the heat wave, and the buses were recharged only during off hours when the grid was not strained.

California energy officials have high hopes that this new power source, called bidirectional charging, will boost California’s power supply as it ramps up its ambitious agenda of electrifying its cars, trucks and buses while switching to 100% clean energy.

Gov. Gavin Newsom called two-way charging technology a “game changer,” saying “this is the future” during a speech last September, about a week after the heat wave ended.

This year, a bill already approved by the state Senate in a 29-9 vote would require all new electric cars sold in California to be equipped with bidirectional technology by 2030. In the Assembly, two committees approved the bill earlier this month and it is now under consideration by a third.

This two-way charging has big potential — but also faces big obstacles. By 2035, California expects to have 12.5 million electric cars on the road, but it’s an open question how much California can rely on them to feed the grid. Automakers say the technology would add thousands of dollars to the cost of an electric car, and California’s utilities are still sorting out how to pay ratepayers for selling them the kilowatt hours.

The ability to use electric cars, trucks and buses to feed energy back into the grid would be especially helpful during peak times for energy use, such as heatwaves. But relying on vehicles as a year-round power source may not be practical — at least not yet.

“It’s a great idea conceptually…but we haven’t had the time to flesh out the details of what needs to happen for California to be able to power itself on electric vehicles,” said Orville Thomas, state policy director for CALSTART, a sustainable energy nonprofit.

“It should be on the menu of options that California has. Is it going to be the number one option? Definitely not.”

So far, its use has been limited in California. Pacific Gas and Electric has a pilot program — the first in the nation — that lets up to 1,000 residential customers with bidirectional chargers sell power back to the utility. Some school districts also are experimenting with it.

Only about half a dozen electric car models currently are equipped with bidirectional capabilities, including the Hyundai Ioniq 5, Nissan Leaf and Ford F-150 Lightning. Tesla announced recently that all its models will have it by 2025.

Electric vehicles convert one type of energy, alternating current electricity, into another, direct current, which is stored in a battery. Bidirectional charging means that an electric vehicle can convert the energy it has stored in its battery and send it to other sources, such as home appliances or back to the grid.

Willett M. Kempton, a University of Delaware professor who has studied bidirectional charging for more than two decades, said the vast majority of the time a vehicle is parked and not using electricity.

“Five percent of the time you’re using the car and you want to have enough energy — electricity or gasoline — to get to where you’re going and back. But most of the time, it’s just sitting there and some other use could be made of it,” he said.

Kempton said these vehicles, properly managed, could be sources of reserve energy, supplanting backup sources that burn fossil fuels. 

Gregory Poilasne, co-founder and CEO of Nuvve Holding Corp., which sells electric fleet charging services, said a big challenge is that cars are unreliable energy assets. “At any time, somebody might come in and unplug the car,” he said. But he added, as the technology becomes more reliable and affordable, bidirectional cars and fleets should increase. 

The cost: $3,700 per car

In Denmark, bidirectional charging earns electric vehicle fleet owners who sell power to the grid $3,000 per vehicle a year, Poilasne said, adding that this reduces the average total cost of electric car ownership by about 40%.

But citing the high cost, automakers oppose the Senate bill that would mandate the chargers for all new cars sold in California by 2030. It would increase the average cost of an electric car by $3,700, according to an opposition letter written by Curt Augustine of the Alliance for Automotive Innovation, which represents General Motors, Ford and other major auto companies.

About $3,000 of that cost would be adding battery capacity to meet warranty requirements, while other costs are for hardware and software.

“This technology is a competitive matter between vehicle manufacturers and should remain that way,” Augustine wrote. “Not all customers will see an advantage of bidirectional charging, and therefore, should not have to pay more for a technology that they will not use.”

Thomas of CALSTART agreed, saying it should be optional.

“There might be a situation where there are people that want to do it and will pay a little extra for a car that is bidirectional, but there will also be people that just want to use a vehicle for driving,” he said. “Do we raise the price of electric vehicles for everybody?”

But Sen. Nancy Skinner, a Democrat from Oakland who authored SB 233, said she wants to ensure that automakers don’t reserve the technology for only their higher-end models. She said since the relatively affordable Nissan Leaf has it, it can be widely available.

Skinner said all consumers would benefit from the technology by selling energy to the grid or using the energy in emergencies. But she said another important reason is that it could end reliance on diesel generators during power emergencies like during wildfires.

“If you have an EV you don’t need that diesel generator,” Skinner said. “Why would we want to encourage diesel generators? They’re extremely polluting.”

Jeffrey Lu, an air pollution specialist with the California Energy Commission’s vehicle-grid integration unit, said the state is working with owners to identify the best times to charge — called smart charging — to protect the grid. Bidirectional charging takes the concept a step further, he said.

The Energy Commission is not yet ready to say how reliant California will be on bidirectional charging to provide sufficient power and meet the state’s 2045 mandate for carbon-free electricity.

“We’re fairly early in this process. California is very committed to load flexibility broadly, but where that load flexibility specifically comes from, how many megawatts or gigawatts are coming from any particular kind of resource? We’re working on that,” he said.

California’s utilities are running pilot projects and studying how bidirectional charging might work and how electric car owners could be compensated for selling energy to the grid.

The California Public Utilities Commission has studied the issue for more than a decade, said spokesperson Terrie D. Prosper, including funding pilot projects and establishing two working groups.

Last year many utilities signed a “Vehicle to Everything” memorandum of understanding with car manufacturers, state agencies, the federal government and others seeking to accelerate all aspects of bidirectional charging.

Southern California Edison, which serves about 5 million businesses and residences, wants to go beyond using bidirectional charging as just an emergency backup. 

Chanel Parson, Edison’s director of electrification, said the utility is working on a rate program that would allow customers to sell their power back to the grid every day of the year. 

“By selling it back to the grid when our rates are more expensive, then that actually helps reduce customers’ energy bills. And it could be so economically attractive that they’re actually making money,” she said.

Pacific Gas and Electric, which serves 5.5 million electric customers in Northern California, said it is aggressively looking to build what it calls a robust vehicle-to-grid-integration. It has partnerships with BMW of North America, Ford Motor Company and General Motors exploring bidirectional charging.

The utility last year launched the nation’s first bidirectional charging pilot available to residential customers, offering up to 1,000 customers $2,500 for enrolling and up to an additional $2,175, depending on their participation.

The Los Angeles Department of Water and Power also is conducting a pilot project using a small fleet of its Nissan Leafs. The utility hopes the technology will eventually provide power during peak load times. 

“Five years is definitely within reach,” said José María Paz, the utility’s project manager for vehicle-to-grid integration. “Technology is advancing quite fast.”

School buses are a test case

The electric school buses at the Cajon Valley Union School District in San Diego County are among a number of school district pilot projects in California. Experts see school buses as a good option for two-way charging because they have set routes and are often parked during peak load times between 4 p.m. and 9 p.m.

Nationally, Nuvve has about 350 school buses connected to its platform.

At the Cajon Valley district, eight electric buses sent 767 kilowatt hours of power back to the grid during the heat wave between Aug. 17 and Sept. 9, according to Nuvve.

Working with Nuvve, the buses power up when energy is less expensive, said Tysen Brodwolf, the district’s transportation director. Brodwolf said there are still several quirks, including the chargers not communicating properly with the grid or someone improperly plugging in a bus.

“But we’re getting there every day,” Brodwolf said. “We’re working through all those bumps and obviously, when you take on a pilot project, you have to take that into consideration that things aren’t necessarily going to go smoothly.”
