Electric vehicle owners can get paid to sell electricity back to the grid

Electric Vehicle Charging Costs and Times explain kWh usage, electricity rates, Level 2 vs DC fast charging, per-mile expense, and tax credits, with examples by region and battery size to estimate home and public charging.

Key Points

They measure EV charging price and duration based on kWh rates, charger level, efficiency, and location.

✅ Costs vary by kWh price, region, and charger type.

✅ Efficiency (mi/kWh) sets per-mile cost and range.

✅ Tax credits and utility rates impact total ownership.

More and more car manufacturing companies dip their toes in the world of electric vehicles every year, making it a good time to buy an EV for many shoppers, and the U.S. government is also offering incentives to turn the tides on car purchasing. Electric vehicles bought between 2010 and 2022 may be eligible for a tax credit of up to $7,500. 

And according to the Consumer Reports analysis on long-term ownership, the cost of charging an electric vehicle is almost always cheaper than fueling a gas-powered car – sometimes by hundreds of dollars.

But that depends on the type of car and where in the country you live, in a market many expect to be mainstream within a decade across the U.S. Here's everything you need to know.

How much does it cost to charge an electric car?
An electric vehicle’s fuel efficiency can be measured in kilowatt-hours per 100 miles, and common charging-efficiency myths have been fact-checked to correct math errors.

For example, if electricity costs 10.7 cents per kilowatt-hour, charging a 200-mile range 54-kWh battery would cost about $6. Charging a vehicle that consumes 27 kWh to travel 100 miles would cost three cents a mile. 

The national average cost of electricity is 10 cents per kWh and 11.7 cents per kWh for residential use. Idaho National Laboratory’s Advanced Vehicle Testing compares the energy cost per mile for electric-powered and gasoline-fueled vehicles.

For example, at 10 cents per kWh, an electric vehicle with an efficiency of 3 miles per kWh would cost about 3.3 cents per mile. The gasoline equivalent cost for this electricity cost would be just under $2.60 per gallon.

Prices vary by location as well. For example, Consumer Report found that West Coast electric vehicles tend to be less expensive to operate than gas-powered or hybrid cars, and are often better for the planet depending on local energy mix, but gas prices are often lower than electricity in New England.

Public charging networks in California cost about 30 cents per kWh for Level 2 and 40 cents per kWh for DCFC. Here’s an example of the cost breakdown using a Nissan LEAF with a 150-mile range and 40-kWh battery:

Level 2, empty to full charge: $12
DCFC, empty to full charge: $16

Many cars also offer complimentary charging for the first few years of ownership or provide credits to use for free charging. You can check the full estimated cost using the Department of Energy’s Vehicle Cost Calculator as the grid prepares for an American EV boom in the years ahead.

How long does it take to charge an electric car?
This depends on the type of charger you're using. Charging with a Level 1 charger takes much longer to reach full battery than a level 2 charger or a DCFC, or Direct Current Fast Charger. Here's how much time you can expect to spend charging your electric vehicle:

California EV mandate will phase out new gas cars, raising power demand and requiring renewable energy, grid upgrades, fast chargers, time-of-use rates, and vehicle-to-grid to stabilize loads and reduce emissions statewide.

Key Points

California's order ends new gas-car sales by 2035, driving grid upgrades, charging infrastructure, and cleaner transport.

✅ 25% higher power demand requires new generation and storage

✅ Time-of-use pricing and midday charging reduce grid stress

✅ Vehicle-to-grid and falling battery costs enable reliability

Leaning on the hood of a shiny red electric Ford Mustang, California Gov. Gavin Newsom signed an executive order Wednesday to end the sale of new gas-burning cars in his state in 15 years, a move with looming challenges for regulators and industry.

Now comes the hard part.

Energy consultants and academics say converting all passenger cars and trucks to run on electricity in California could raise power demand by as much as 25%. That poses a major challenge to state power grids as California is already facing periodic rolling blackouts as it rapidly transitions to renewable energy.

California will need to boost power generation, scale up its network of fast charging stations, enhance its electric grid to handle the added load and hope that battery technology continues to improve enough that millions in America’s most populous state can handle long freeway commutes to schools and offices without problems.

“We’ve got 15 years to do the work,” said Pedro Pizarro, chief executive of Edison International, owner of Southern California Edison, a utility serving 15 million people in the state. “Frankly the state agencies are going to have to do their part. We’ve got to get to the permitting processes, the approvals; all of that work is going to have to get accelerated to meet [Wednesday’s] target.”

Switching from petroleum fuels to electricity to phase out the internal combustion engine won’t happen all at once—Mr. Newsom’s order applies to sales of new vehicles, so older gas-powered cars will be on the road in California for many years to come. But the mandate means the state will face a growing demand for megawatts.

California is already facing a shortfall of power supplies over the next couple of years. The problem was highlighted last month when a heat wave blanketed the western U.S. and the state’s grid operator instituted rolling blackouts on two occasions.

“It is too early to tell what kind of impact the order will have on our power grid, and we don’t have any specific analysis or projections,” said Anne Gonzalez, a spokeswoman for the California Independent System Operator, which runs the grid.

Currently, California faces a crunchtime in the early evening as solar power falls off and demand to power air conditioners remains relatively high. Car charging presents a new potential issue: what happens if surging demand threatens to crash the grid during peak hours?

Caroline Winn, the chief executive of San Diego Gas & Electric, a utility owned by Sempra Energy that serves 3.6 million people, said there will need to be rules and rates that encourage people to charge their cars at certain times of the day, amid broader control over charging debates.

“We need to get the rules right and the markets right, informed by lessons from 2021, in order to resolve this issue because certainly California is moving that way,” she said.

The grid will need to be upgraded to prepare for millions of new electric vehicles. The majority of people who own them usually charge them at home, which would mean changes to substations and distribution circuits to accommodate multiple homes in a neighborhood drawing power to fill up batteries. The state’s three main investor-owned utilities are spending billions of dollars to harden the grid to prevent power equipment from sparking catastrophic wildfires.

“We have a hell of a lot of work to do nationally. California is ahead of everybody and they have a hell of a lot of work to do,” said Chris Nelder, who studies EV-grid integration at the Rocky Mountain Institute, an energy and environment-policy organization that promotes clean-energy solutions.

Mr. Nelder believes the investment will be worth it, because internal combustion engines generate so much waste heat and emissions of uncombusted hydrocarbons that escape out of tailpipes. Improving energy efficiency by upgrading the electrical system could result in lower bills for customers. “We will eliminate a vast amount of waste from the energy system and make it way more efficient,” he said.

Some see the growth of electric vehicles as an opportunity more than a challenge. In the afternoon, when electricity demand is high but the sun is setting and solar power drops off quickly, batteries in passenger cars, buses and other vehicles could release power back into the electric grid to help grid stability across the system, said Matt Petersen, chairman of the Transportation Electrification Partnership, a public-private effort in Los Angeles to accelerate the deployment of electric vehicles.

The idea is known as “vehicle-to-grid” and has been discussed in a number of countries expanding EV use, including the U.K. and Denmark.

“We end up with rolling batteries that can discharge power when needed,” Mr. Petersen said, adding, “The more electric vehicles we add to the grid, the more renewable energy we can add to the grid.”

One big hurdle for the widespread deployment of electric cars is driving down the cost of batteries to make the cars more affordable. This week, Tesla Inc. Chief Executive Elon Musk said he expected to have a $25,000 model ready by about 2023, signaling a broader EV boom in the U.S.

Shirley Meng, director of the Sustainable Power and Energy Center at the University of California, San Diego, said she believed batteries would continue to provide better performance at a lower cost.

“I am confident the battery technology is ready,” she said. Costs are expected to fall as new kinds of materials and metals can be used in the underlying battery chemistry, dropping prices. “Batteries are good now, and they will be better in the next 10 years.”

John Eichberger, executive director of the Fuels Institute, a nonprofit research group launched by the National Association of Convenience Stores, said he hoped that the California Air Resources Board, which is tasked with developing new rules to implement Mr. Newsom’s order, will slow the timeline if the market and electric build-out is running behind.

“We need to think about these critical infrastructure issues because transportation is not optional,” he said. “How do we develop a system that can guarantee consumers that they can get the energy when they need it?”

Global Renewable Capacity Additions 2023 surge on policy momentum, high fossil prices, and energy security, with solar PV and wind leading growth as grids expand and manufacturing scales across China, Europe, India, and the US.

Key Points

Record solar PV and wind growth from policy and energy security, adding 440+ GW toward 4,500 GW total capacity in 2024.

✅ Solar PV to supply two-thirds of additions; rooftop demand rising.

✅ Wind rebounds ~70% as delayed projects complete in China, EU, US.

✅ Grid upgrades and better permitting, auctions key for 2024 growth.

Global additions of renewable power capacity are expected to jump by a third this year as growing policy momentum, higher fossil fuel prices and energy security concerns drive strong deployment of solar PV and wind power, building on a record year for renewables in 2016, according to the latest update from the International Energy Agency.

The growth is set to continue next year with the world’s total renewable electricity capacity rising to 4 500 gigawatts (GW), equal to the total power output of China and the United States combined, and in the United States wind power has surged in the electricity mix, says the IEA’s new Renewable Energy Market Update, which was published today.

Global renewable capacity additions are set to soar by 107 gigawatts (GW), the largest absolute increase ever, to more than 440 GW in 2023. The dynamic expansion is taking place across the world’s major markets. Renewables are at the forefront of Europe’s response to the energy crisis, accelerating their growth there. New policy measures are also helping drive significant increases in the United States, where solar and wind growth remains strong, and India over the next two years. China, meanwhile, is consolidating its leading position and is set to account for almost 55% of global additions of renewable power capacity in both 2023 and 2024.

“Solar and wind are leading the rapid expansion of the new global energy economy. This year, the world is set to add a record-breaking amount of renewables to electricity systems – more than the total power capacity of Germany and Spain combined,” said IEA Executive Director Fatih Birol. “The global energy crisis has shown renewables are critical for making energy supplies not just cleaner but also more secure and affordable – and governments are responding with efforts to deploy them faster. But achieving stronger growth means addressing some key challenges. Policies need to adapt to changing market conditions, and we need to upgrade and expand power grids to ensure we can take full advantage of solar and wind’s huge potential.”

Solar PV additions will account for two-thirds of this year’s increase in renewable power capacity and are expected to keep growing in 2024, according to the new report. The expansion of large-scale solar PV plants is being accompanied by the growth of smaller systems. Higher electricity prices are stimulating faster growth of rooftop solar PV, which is empowering consumers to slash their energy bills, and in the United States renewables' share is projected to approach one-fourth of electricity generation.

At the same time, manufacturing capacity for all solar PV production segments is expected to more than double to 1 000 GW by 2024, led by China's solar PV growth and increasing supply diversification in the United States, where wind, solar and battery projects dominate the 2023 pipeline, India and Europe. Based on those trends, the world will have enough solar PV manufacturing capacity in 2030 to comfortably meet the level of annual demand envisaged in the IEA’s Net Zero Emissions by 2050 Scenario.

Wind power additions are forecast to rebound sharply in 2023 growing by almost 70% year-on-year after a difficult couple of years in which growth was slugging, even as wind power still grew despite Covid-19 challenges. The faster growth is mainly due to the completion of projects that had been delayed by Covid-19 restrictions in China and by supply chain issues in Europe and the United States. However, further growth in 2024 will depend on whether governments can provide greater policy support to address challenges in terms of permitting and auction design. In contrast to solar PV, wind turbine supply chains are not growing fast enough to match accelerating demand over the medium-term. This is mainly due to rising commodity prices and supply chain challenges, which are reducing the profitability of manufacturers.

The forecast for renewable capacity additions in Europe has been revised upwards by 40% from before Russia’s invasion of Ukraine, which led many countries to boost solar and wind uptake to reduce their reliance on Russian natural gas. The growth is driven by high electricity prices that have made small-scale rooftop solar PV systems more financially attractive and by increased policy support in key European markets, especially in Germany, Italy and the Netherlands.

US Renewable Energy Growth drives the US electricity mix as wind, solar, and hydropower rise while coal, natural gas, and nuclear decline, boosting market share month over month and year over year across the grid.

Key Points

US Renewable Energy Growth tracks rising wind, solar, and hydro shares in the mix as coal, gas, and nuclear decline.

✅ Wind and solar surpass nuclear in April share

✅ Renewables reach 29.3% of US electricity in April

✅ Coal and natural gas shares trend lower since 2020

Electricity generated by renewable energy sources continues to grow month over month and year over year in the United States. In April 2022, the share of US electricity coming from renewable energy was up to 29.3%, surpassing a record April level reported previously in national data. That was up from 24.8% in April 2020 and 25.7% in April 2021.

Looking at the first four months of the year, renewables provided 25.5% of US electricity, and were the second-most U.S. source in 2020 as well, while the figure for January–April 2020 was 21.7% and the figure for January–April 2021 was 22.5%.

Coal power (20.2% of US electricity) was down year over year in this time period (from 22% in January–April 2021), even as renewables surpassed coal in 2022 nationwide, but is admittedly still a bit higher than it was in January–April 2020 (16.8%).

Electricity from natural gas is also down year over year, but only very slightly (34.7% for both years). Though, it has dropped significantly since January–April 2020 (39.6%).

Electricity from nuclear power continued to take a steady, step-by-step tumble.

Wind & Solar Power Growth Strong
As reported earlier, April was the first month that wind and solar power provided more electricity than nuclear across the United States. Wind and solar power provided 21% of US electricity, while nuclear power provided 17.8% of US electricity (coal, incidentally, also provided 17.8% of US electricity, but wind and solar had provided more electricity than coal in some previous months as well).

Wind and solar power’s combined market share for the first four months of the year was up from just 14.6% in 2020 and 18.4% in 2021.

Looking at their growth year over year, you can see strong and continuous expansion of solar-provided electricity and wind-provided electricity, amid favorable government plans that have supported deployment.

Solar grew from 2.9% in January–April 2020 to 3.6%in January–April 2021 to, eventually, 4.4% in January–April 2022, with solar's 2022 share rising to 4.7% for the full year. Wind rose from 9.2% to 10.3% to 12.2%.

Together, wind and solar were up from 12.1% in January–April 2020 to 13.9% in January–April 2021, reflecting a surge in wind power within the U.S. electricity mix over this period, to 16.7% January–April 2022.

Hydropower (6.5%) is holding approximately the same position as the same period in 2021 (6.5%), but it is down a significant chunk from April 2020 (8.2%).

Clean Electricity Standard drives Biden's infrastructure, grid decarbonization, and utility mandates, leveraging EPA regulation, renewables, nuclear, and carbon capture via reconciliation to reach 80% clean power by 2030 amid partisan Congress.

Key Points

A federal mandate to reach 80% clean U.S. power by 2030 using incentives and EPA rules to speed grid decarbonization.

✅ Targets 80% clean electricity by 2030 via Congress or reconciliation

✅ Mix of renewables, nuclear, gas with carbon capture allowed

✅ Backup levers: EPA rules, incentives, utility planning shifts

The true measure of President Biden’s climate ambition may be the clean electricity standard he tucked into his massive $2.2 trillion infrastructure spending plan.

Its goal is striking: 80% clean power in the United States by 2030.

The details, however, are vague. And so is Biden’s plan B if it fails—an uncertainty that’s worrisome to both activists and academics. The lack of a clear backup plan underscores the importance of passing a clean electricity standard, they say.

If the clean electricity standard doesn’t survive Congress, it will put pressure on the need to drive climate policy through targeted spending, said John Larsen, a power system analyst with the Rhodium Group, an economic consulting firm.

“I don’t think the game is lost at all if a clean electricity standard doesn’t get through in this round,” Larsen said. “But there’s a difference between not passing a clean electricity standard and passing the right spending package.”

In his few months in office, Biden has outlined plans to bring the United States back into the international Paris climate accord, pause oil and gas leasing on public lands, boost the electric vehicle market, and target clean energy investments in vulnerable communities, including plans to revitalize coal communities across the country, most affected by climate change.

But those are largely executive orders and spending proposals—even as early assessments show mixed results from climate law—and unlikely to last beyond his administration if the next president favors fossil fuel usage over climate policy. The clean electricity standard, which would decarbonize 80% of the electrical grid by 2030, is different.

It transforms Biden’s climate vision from a goal into a mandate. Passing it through Congress makes it that much harder for a future administration to undo. If Biden is in office for two terms, the United States would see a rate of decarbonization unparalleled in its history that would set a new bar for most of the world’s biggest economies.

But for now, the clean electricity standard faces an uncertain path through Congress and steep odds to getting enacted. That means there’s a good chance the administration will need a plan B, observers said.

Exactly what kind of climate spending can pass Congress is the very question the White House and congressional Democrats will be working on in the next few months, including upgrades to an aging power grid that affect renewables and EVs, as the infrastructure bill proceeds through Congress.

Negotiations are fraught already. Congress is almost evenly split between a party that wants to curtail the use of fossil fuels and another that wants to grow them, and even high energy prices have not necessarily triggered a green transition in the marketplace.

Senate Minority Leader Mitch McConnell (R-Ky.) said last week that “100% of my focus is on stopping this new administration.” He made similar comments at the start of the Obama administration and blocked climate policy from getting through Congress. He also said last week that no Republican senators would vote for Biden’s infrastructure spending plan.

A clean electricity standard has been referred to as the “backbone” of Biden’s climate policy—a way to ensure his policies to decarbonize the economy outlast a future president who would seek to roll back his climate work. Advocates say hitting that benchmark is an essential milestone in getting to a carbon-free grid by 2035. Much of President Obama’s climate policy, crafted largely through regulations and executive orders, proved vulnerable to President Trump’s rollbacks.

Biden appears to have learned from those lessons and wants to chart a new course to mitigate the worst effects of climate change. He’s using his majority in the House and Senate to lock in whatever he can before the 2022 midterms, when Democrats are expected to lose the House.

To pass a clean electricity standard, virtually every Democrat must be on board, and even then, the only chance of success is to pass a bill through the budget reconciliation process that can carry a clean electricity standard. Some Senate Democrats have recently hinted that they were willing to split the bill into pieces to get it through, while others are concerned that although this approach might win some GOP support on traditional infrastructure such as roads and bridges, it would isolate the climate provisions that make up more than half of the bill.

The most durable scenario for rapid electricity-sector decarbonization is to lock in a bipartisan clean electricity standard into legislation with 60 votes in the Senate, said Mike O’Boyle, the director of electricity policy for Energy Innovation. Because that’s highly unlikely—if not impossible—there are other paths that could get the United States to the 80% goal within the next decade.

“The next best approach is to either, or in combination, pursue EPA regulation of power plant pollution from existing and new power plants as well as to take a reconciliation-based approach to a clean electricity standard where you’re basically spending federal dollars to provide incentives to drive clean electricity deployment as opposed to a mandate per se,” he said.

Either way, O’Boyle said the introduction of the clean electricity standard sets a new bar for the federal government that likely would drive industry response even if it doesn’t get enacted. He compared it to the Clean Power Plan, Obama’s initiative to limit power plant emissions. Even though the plan never came to fruition, because of a Clean Power Plan rollback, it left a legacy that continues years later and wasn’t negated by a president who prioritized fossil fuels over the climate, he said.

“It never got enacted, but it still created a titanic shift in the way utilities plan their systems and proactively reposition themselves for future carbon regulation of their electricity systems,” O’Boyle said. “I think any action by the Biden administration or by Congress through reconciliation would have a similar catalytic function over the next couple years.”

Some don’t think a clean electricity standard has a doomed future. Right now, its provisions are vague. But they can be filled in in a way that doesn’t alienate Republicans or states more hesitant toward climate policy, said Sally Benson, an engineering professor at Stanford University and an expert on low-carbon energy systems. The United States is overdue for a federal mandate that lasts through multiple administrations. The only way to ensure that happens is to get Republican support.

She said that might be possible by making the clean electricity standard more flexible. Mandate the goals, she said, not how states get there. Going 100% renewable is not going to sell in some states or with some lawmakers, she added. For some regions, flexibility will mean keeping nuclear plants open. For others, it would mean using natural gas with carbon capture, Benson said.

While it might not meet the standards some progressives seek to end all fossil fuel usage, it would have a better chance of getting enacted and remaining in place through multiple presidents, she said. In fact, a clean electricity standard would provide a chance for carbon capture, which has been at the center of Republican climate policy proposals. Benson said carbon capture is not economical now, but the mandate of a standard could encourage investments that would drive the sector forward more rapidly.

“If it’s a plan that people see as shutting the door to nuclear or to natural gas plus carbon capture, I think we will face a lot of pushback,” she said. “Make it an inclusive plan with a specific goal of getting to zero emissions and there’s not one way to do it, meaning all renewables—I think that’s the thing that could garner a lot of industrial support to make progress.”

In addition to industry, Biden’s proposed clean electricity standard would drive states to do more, said Larsen of the Rhodium Group. Several states already have their own version of a clean energy standard and have driven much of the national progress on carbon emissions reduction in the last four years, he said. Biden has set a new benchmark that some states, including those with some of the biggest economies in the United States, would now likely exceed, he said.

“It is rare for the federal government to get out in front of leading states in clean energy policy,” he said. “This is not usually how climate policy diffusion works from the state level to the federal level; usually it’s states go ahead and the federal government adopts something that’s less ambitious.”

ABB Terra 360 EV Charger offers 360 kW DC fast charging, ultra-fast top-ups, and multi-vehicle capability for Ionity, Electrify America, and depot installations, adding 100 km in under 3 minutes with compact footprint.

Key Points

ABB's Terra 360 is a 360 kW DC fast charger for EVs, powering up to four vehicles simultaneously with a compact footprint.

✅ 360 kW DC output; adds 100 km in under 3 minutes

✅ Charges up to four vehicles at once; small footprint

✅ Rolling out in Europe 2021; US and beyond in 2022

Swiss company ABB, which supplies EV chargers to Ionity and Electrify America amid intensifying charging network competition worldwide, has unveiled what it calls the "world's fastest electric car charger." As its name suggests, the Terra 360 has a 360 kW capacity, and as electric-car adoption accelerates, it could fully charge a (theoretical) EV in 15 minutes. More realistically, it can charge four vehicles simultaneously, saving space at charging stations. 

The Terra 360 isn't the most powerful charger by much, as companies like Electrify America, Ionity and EVGo have been using 350 kW chargers manufactured by ABB and others since at least 2018. However, it's the "only charger designed explicitly to charge up to four vehicles at once," the company said. "This gives owners the flexibility to charge up to four vehicles overnight or to give a quick refill to their EVs in the day." They also have a relatively small footprint, allowing installation in small depots or parking lots, helping as US automakers plan 30,000 new chargers nationwide. 

There aren't a lot of EVs that can handle that kind of charge. The only two approaching it are Porsche's Taycan, with 270 kW of charging capacity and the new Lucid Air, which allows for up to 300 kW fast-charging. Tesla's Model 3 and Model Y EVs can charge at up to 250 kW, while Hyundai's Ioniq 5 is rated for 232 kW DC fast charging in optimal conditions. 

Such high charging levels aren't necessarily great for an EV's battery, and the broader grid capacity question looms as the American EV boom gathers pace. Porsche, for instance, has a battery preservation setting on its Plug & Charge Taycan feature that lowers power to 200 kW from the maximum 270 kW allowed — so it's essentially acknowledging that faster charging degrades the battery. On top of that, extreme charging levels don't necessarily save you much time, as Car and Driver found. Tesla recently promised to upgrade its own Supercharger V3 network from 250kW to 300kW, with energy storage solutions emerging to buffer high-power sites. 

ABB's new chargers will be able to add 100 km (62 miles) of range in less than three minutes. They'll arrive in Europe by the end of the year and start rolling out in the US and elsewhere in 2022.
