Higher price of electric cars a concern for more than half of UK consumers

US Solar Power 2050 Target projects 45% electricity from solar, advancing decarbonization with clean energy, wind, nuclear, hydropower, hydrogen, and scalable energy storage, while modernizing the grid and transmission to cut emissions and create jobs.

Key Points

A goal for solar to supply ~45% of US electricity by 2050, backed by energy storage and other low-carbon generation.

✅ Requires 1,050-1,570 GW solar and matching storage capacity

✅ Utility-scale buildout uses ~10M acres; rooftop 10-20% of capacity

✅ Complemented by wind, nuclear, hydropower, hydrogen, and flexible turbines

President Joe Biden has called for major clean energy investments as a way to curb climate change and generate jobs. On Sept. 8, 2021, the White House released a report produced by the U.S. Department of Energy that found that solar power could generate up to 45% of the U.S. electricity supply by 2050, compared to less than 4% today, with about 3% in 2020 noted by industry observers. The Conversation asked Joshua D. Rhodes, an energy technology and policy researcher at the University of Texas at Austin, what it would take to meet this target.

Why such a heavy focus on solar power? Doesn’t a low-carbon future require many types of clean energy, even though wind and solar could meet about 80% of demand according to some research?
The Energy Department’s Solar Futures Study lays out three future pathways for the U.S. grid: business as usual; decarbonization, meaning a massive shift to low-carbon and carbon-free energy sources; and decarbonization with economy-wide electrification of activities that are powered now by fossil fuels.

It concludes that the latter two scenarios would require approximately 1,050-1,570 gigawatts of solar power, which would meet about 44%-45% of expected electricity demand in 2050, even as renewables approach one-fourth of U.S. generation in the near term. For perspective, one gigawatt of generating capacity is equivalent to about 3.1 million solar panels or 364 large-scale wind turbines.

The rest would come mostly from a mix of other low- or zero-carbon sources, including wind, nuclear, hydropower, biopower, geothermal and combustion turbines run on zero-carbon synthetic fuels such as hydrogen. Energy storage capacity – systems such as large installations of high-capacity batteries – would also expand at roughly the same rate as solar, with record growth in solar and storage anticipated by industry in coming years.

One advantage solar power has over many other low-carbon technologies is that most of the U.S. has lots of sunshine. Wind, hydropower and geothermal resources aren’t so evenly distributed: There are large zones where these resources are poor or nonexistent.

Relying more heavily on region-specific technologies would mean developing them extremely densely where they are most abundant. It also would require building more high-voltage transmission lines to move that energy over long distances, which could increase costs and draw opposition from landowners – a key reason the grid isn't yet 100% renewable according to experts – in many regions.

Is generating 45% of U.S. electricity from solar power by 2050 feasible?
I think it would be technically possible but not easy. It would require an accelerated and sustained deployment far larger than what the U.S. has achieved so far, even as the cost of solar panels has fallen dramatically, and wind, solar and batteries are 82% of the utility-scale pipeline across the country. Some regions have attained this rate of growth, albeit from low starting points and usually not for long periods.

The Solar Futures Study estimates that producing 45% of the nation’s electricity from solar power by 2050 would require deploying about 1,600 gigawatts of solar generation. That’s a 1,450% increase from the 103 gigawatts that are installed in the U.S. today, even as wind and solar trend toward 30% of U.S. electricity in some outlooks. For perspective, there are currently about 1,200 gigawatts of electricity generation capacity of all types on the U.S. power grid.

The report assumes that 10%-20% of this new solar capacity would be deployed on homes and businesses. The rest would be large utility-scale deployments, mostly solar panels, plus some large-scale solar thermal systems that use mirrors to reflect the sun to a central tower.

Assuming that utility-scale solar power requires roughly 8 acres per megawatt, this expansion would require approximately 10.2 million to 11.5 million acres. That’s an area roughly as big as Massachusetts and New Jersey combined, although it’s less than 0.5% of total U.S. land mass.

I think goals like these are worth setting, but are good to reevaluate over time to make sure they represent the most prudent path.

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:

U.S. Renewable Energy Record 28% signals a cleaner power grid as wind, solar, and hydroelectric output soar; EIA data shows cost-competitive clean energy reshaping the electricity mix and reducing carbon emissions across regions.

Key Points

EIA-reported April share of electricity from wind, solar, and hydro, reflecting cost-driven growth in U.S. clean power.

✅ Wind, solar additions dominated recent U.S. capacity buildouts

✅ Lower levelized costs make renewables most competitive

✅ Seasonal factors and outages lowered fossil and nuclear output

The amount of electricity generated by renewable resources hit a record 28% in April, a breakthrough number that shows how important renewable energy has become in U.S. energy markets as it surpassed coal in 2022 overall.

"It's a 'Wow' moment," said Peter Kelly-Detwiler, an energy analyst and author of "The Energy Switch," a recent book about the transition to a carbon-free energy economy.

The percentage of U.S. electricity produced by renewable energy from wind, solar and hydroelectric dams has been steadily rising, from 8.6% in April 2001 to this April's 28%. Those numbers were released this week by the U.S. Energy Information Administration, which tracks energy data for the nation.

What explains the surge?
There are several reasons. At the top is that wind and solar installations dominated U.S. energy buildouts.

"Basically, the only things we've added to the grid in the past decade are wind, solar and natural gas," said Harrison Fell, an economist and engineer at Columbia University, where he co-leads the Power Sector and Renewables Research Initiative.

That's happening for two reasons. The first is cost. Renewables are simply the most economically competitive power currently available, Kelly-Detwiler said.

In 2021, the cost of producing a megawatt-hour of electricity from a new wind turbine was $26 to $50. The same amount of electricity from the cheapest type of natural gas plant ranged from $45 to $74, according to Lazard, a financial advisory firm that publishes annual estimates of the cost of producing electricity. 

Federal and state mandates and incentives to increase the amount of clean energy used also help, Fell said, as renewables reached 25.5% of U.S. electricity recently. 

"When you do the math on what's the most profitable thing to add, it's often going to be wind and solar at this stage," he said.

Was weather a factor?
Yes. April tends to be a particularly windy month, and this spring was windier than most, Fell said.

There's also less power coming into the grid from fossil fuels and nuclear in the spring. That's because electricity demand is generally lower because of the mild weather and fossil fuel and nuclear power plants use the time for maintenance and refueling, which reduces their production, he said.

Another surprise was that in April, wind and solar power together produced more electricity than nuclear plants nationwide. 

Historically, nuclear power plants, which are carbon-neutral, have reliably produced about 20% of America's electricity. In April that number dropped to 18% while wind and solar combined stood at 19.6%.

The nuclear decrease is partly a result of the shutdown of two plants in the past year, Indian Point in New York state and Palisades in Michigan, as well as scheduled closures for maintenance.

Will the trend continue?
When all U.S. carbon-neutral energy sources are added together – nuclear, wind, hydroelectric and solar – almost 46% of U.S. electricity in April came from sources that don't contribute greenhouse gases to the environment, federal data shows.  

"It's a milestone," Kelly-Detwiler said. "But in a few years, we'll look back and say, 'This was a nice steppingstone to the next 'Wow!' moment."

Electric vehicles may cost more upfront but often save money long-term. A new MIT study shows the total cost of EV ownership is lower than gas cars when factoring in fuel, maintenance, and emissions.

Total cost of EV ownership is the focus of new MIT research showing electric vehicles offer both financial and environmental benefits over time.

✅ Electric vehicles cost more upfront but save money over their lifetime through lower fuel and maintenance costs

✅ MIT study confirms EVs have lower emissions and total ownership costs than most gas-powered cars

✅ New interactive tool helps consumers compare climate and cost impacts of EVs, hybrids, and traditional vehicles

Electric vehicles are better for the climate than gas‑powered cars, but many Americans are still reluctant to buy them. One reason: The larger upfront cost.

New data published Thursday shows that despite the higher sticker price, electric cars may actually save drivers money in the long-run.

To reach this conclusion, a team at the Massachusetts Institute of Technology calculated both the carbon dioxide emissions and full lifetime cost — including purchase price, maintenance and fuel — for nearly every new car model on the market.

They found electric cars were easily more climate friendly than gas-burning ones. Over a lifetime, they were often cheaper, too.

Jessika Trancik, an associate professor of energy studies at M.I.T. who led the research, said she hoped the data would “help people learn about how those upfront costs are spread over the lifetime of the car.”

For electric cars, lower maintenance costs and the lower costs of charging compared with gasoline prices tend to offset the higher upfront price over time. (Battery-electric engines have fewer moving parts that can break compared with gas-powered engines and they don’t require oil changes. Electric vehicles also use regenerative braking, which reduces wear and tear.)

As EV adoption continues to boom, more consumers are realizing the long-term savings and climate benefits. Ontario’s investment in EV charging stations reflects how infrastructure is beginning to catch up with demand. Despite regional energy pricing differences, EV charging costs remain lower than gasoline in nearly every U.S. city.

The cars are greener over time, too, despite the more emissions-intensive battery manufacturing process. Dr. Trancik estimates that an electric vehicle’s production emissions would be offset in anywhere from six to 18 months, depending on how clean the energy grid is where the car is charging.

In some areas, EVs are even being used to power homes, enhancing their value as a sustainable investment. Recent EPA rules aim to boost EV sales, further signaling government support. California leads the nation in EV charging infrastructure, setting a model for nationwide adoption.

The new data showed hybrid cars, which run on a combination of fuel and battery power, and can sometimes be plugged in, had more mixed results for both emissions and costs. Some hybrids were cheaper and spewed less planet-warming carbon dioxide than regular cars, but others were in the same emissions and cost range as gas-only vehicles.

Traditional gas-burning cars were usually the least climate friendly option, though long-term costs and emissions spanned a wide range. Compact cars were usually cheaper and more efficient, while gas-powered SUVs and luxury sedans landed on the opposite end of the spectrum.

Dr. Trancik’s team released the data in an interactive online tool to help people quantify the true costs of their car-buying decisions — both for the planet and their budget. The new estimates update a study published in 2016 and add to a growing body of research underscoring the potential lifetime savings of electric cars.

Take the Tesla Model 3, the most popular electric car in the United States. The M.I.T. team estimated the lifetime cost of the most basic model as comparable to a Nissan Altima that sells for $11,000 less upfront. (That’s even though Tesla’s federal tax incentive for electric vehicles has ended.)

Toyota’s Hybrid RAV4 S.U.V. also ends up cheaper in the long run than a similar traditional RAV4, a national bestseller, despite a higher retail price.

Hawaii, Alaska and parts of New England have some of the highest average electricity costs, while parts of the Midwest, West and South tend to have lower rates. Gas prices are lower along the Gulf Coast and higher in California. But an analysis from the Union of Concerned Scientists still found that charging a vehicle was more cost effective than filling up at the pump across 50 major American cities. “We saw potential savings everywhere,” said David Reichmuth, a senior engineer for the group’s Clean Transportation Program.

Still, the upfront cost of an electric vehicle continues to be a barrier for many would-be owners.

The federal government offers a tax credit for some new electric vehicle purchases, but that does nothing to reduce the initial purchase price and does not apply to used cars. That means it disproportionately benefits wealthier Americans. Some states, like California, offer additional incentives. President-elect Joseph R. Biden Jr. has pledged to offer rebates that help consumers swap inefficient, old cars for cleaner new ones, and to create 500,000 more electric vehicle charging stations, too.

EV sales projections for 2024 suggest continued acceleration, especially as costs fall and policy support expands. Chris Gearhart, director of the Center for Integrated Mobility Sciences at the National Renewable Energy Laboratory, said electric cars will become more price competitive in coming years as battery prices drop. At the same time, new technologies to reduce exhaust emissions are making traditional cars more expensive. “With that trajectory, you can imagine that even immediately at the purchase price level, certain smaller sedans could reach purchase price parity in the next couple of years,” Dr. Gearhart said.

EVs to Power Homes: New Technology Turns Cars Into Backup Batteries

U.S. Electric Vehicle Sales Soar Into 2024

Vehicle-to-Home (V2H) Power enables EVs to act as backup generators and home batteries, using bidirectional charging, inverters, and rooftop solar to cut energy costs, stabilize the grid, and provide resilient, outage-proof electricity.

Key Points

Vehicle-to-Home (V2H) Power lets EV batteries run household circuits via bidirectional charging and an inverter.

✅ Cuts energy bills using solar, time-of-use rates, and storage

✅ Provides resilient backup during outages, storms, and blackouts

✅ Enables grid services via V2G/V2H with smart chargers

When the power went out at Nate Graham’s New Mexico home last year, his family huddled around a fireplace in the cold and dark. Even the gas furnace was out, with no electricity for the fan. After failing to coax enough heat from the wood-burning fireplace, Graham’s wife and two children decamped for the comfort of a relative’s house until electricity returned two days later.

The next time the power failed, Graham was prepared. He had a power strip and a $150 inverter, a device that converts direct current from batteries into the alternating current needed to run appliances, hooked up to his new Chevy Bolt, an electric vehicle. The Bolt’s battery powered his refrigerator, lights and other crucial devices with ease. As the rest of his neighborhood outside Albuquerque languished in darkness, Graham’s family life continued virtually unchanged. “It was a complete game changer making power outages a nonissue,” says Graham, 35, a manager at a software company. “It lasted a day-and-a-half, but it could have gone much longer.”

Today, Graham primarily powers his home appliances with rooftop solar panels and, when the power goes out, his Chevy Bolt. He has cut his monthly energy bill from about $220 to $8 per month. “I’m not a rich person, but it was relatively easy,” says Graham “You wind up in a magical position with no [natural] gas, no oil and no gasoline bill.”

Graham is a preview of what some automakers are now promising anyone with an EV: An enormous home battery on wheels that can reverse the flow of electricity to power the entire home through the main electric panel.

Beyond serving as an emissions-free backup generator, the EV has the potential of revolutionizing the car’s role in American society, with California grid programs piloting vehicle-to-grid uses, transforming it from an enabler of a carbon-intensive existence into a key step in the nation’s transition into renewable energy.

Home solar panels had already been chipping away at the United States’ centralized power system, forcing utilities to make electricity transfer a two-way street. More recently, home batteries have allowed households with solar arrays to become energy traders, recharging when electricity prices are low, replacing grid power when prices are high, and then sell electricity back to the grid for a profit during peak hours.

But batteries are expensive. Using EVs makes this kind of home setup cheaper and a real possibility for more Americans as the American EV boom accelerates nationwide.

So there may be a time, perhaps soon, when your car not only gets you from point A to point B, but also serves as the hub of your personal power plant.

I looked into new vehicles and hardware to answer the most common questions about how to power your home (and the grid) with your car.

Why power your home with an EV battery

America’s grid is not in good shape. Prices are up and reliability is down, and many state power grids face new challenges from rising EV adoption. Since 2000, the number of major outages has risen from less than two dozen to more than 180 per year, based on federal data, the Wall Street Journal reports. The average utility customer in 2020 endured about eight hours of power interruptions, double the previous decade.

Utilities’ relationship with their customers is set to get even rockier. Residential electricity prices, which have risen 21 percent since 2008, are predicted to keep climbing as utilities spend more than $1 trillion upgrading infrastructure, erecting transmission lines for renewable energy and protecting against extreme weather, even though grids can handle EV loads with proper management and planning.

U.S. homeowners, increasingly, are opting out. About 8 percent of them have installed solar panels. An increasing number are adding home batteries from companies such as LG, Tesla and Panasonic. These are essentially banks of battery cells, similar to those in your laptop, capable of storing energy and discharging electricity.

EnergySage, a renewable energy marketplace, says two-thirds of its customers now request battery quotes when soliciting bids for home solar panels, and about 15 percent install them. This setup allows homeowners to declare (at least partial) independence from the grid by storing and consuming solar power overnight, as well as supplying electricity during outages.

But it doesn’t come cheap. The average home consumes about 20 kilowatt-hours per day, a measure of energy over time. That works out to about $15,000 for enough batteries on your wall to ensure a full day of backup power (although the net cost is lower after incentives and other potential savings).

How an EV battery can power your home

Ford changed how customers saw their trucks when it rolled out a hybrid version of the F-150, says Ryan O’Gorman of Ford’s energy services program. The truck doubles as a generator sporting as many as 11 outlets spread around the vehicle, including a 240-volt outlet typically used for appliances like clothes dryers. During disasters like the 2021 ice storm that left millions of Texans without electricity, Ford dealers lent out their hybrid F-150s as home generators, showing how mobile energy storage can bring new flexibility during outages.

The Lightning, the fully electric version of the F-150, takes the next step by offering home backup power. Under each Lightning sits a massive 98 kWh to 131 kWh battery pack. That’s enough energy, Ford estimates, to power a home for three days (10 days if rationing). “The vehicle has an immense amount of power to move that much metal down the road at 80 mph,” says O’Gorman.

France EV Incentive Rules prioritize EU-made electric vehicles, tying subsidies to manufacturing emissions and carbon footprint, making Stellantis, Renault, and Tesla Model Y eligible while excluding many China-built models under a new eligibility list.

Key Points

Links EV subsidies to manufacturing emissions, favoring EU-made models and restricting many China-built cars.

✅ Subsidies tied to lifecycle manufacturing emissions.

✅ EU production favored; many China-built EVs excluded.

✅ Eligible: Stellantis, Renault, Tesla Model Y; not Model 3.

France's revamped new EV rules on consumer cash incentives for electric car purchases favour vehicles made in France and Europe over models manufactured in China, a government list of eligible car types published recently has showed.

Some 65% of electric cars sold in France will be eligible for the scheme, which from Friday will include new criteria covering the amount of carbon emitted in the manufacturing of an electric vehicle (EV).

The list of eligible models includes 24 produced by Franco-Italian group Stellantis (STLAM.MI) and five by French carmaker Renault (RENA.PA). Elon Musk's Tesla (TSLA.O) Model Y will be eligible but not its Model 3.

Electric vehicle brand MG Motors, owned by China's SAIC, said it expects the new rules to weigh on the French EV market, despite the global surge in EV sales seen in recent years.

"There are cars that will entirely lose their competitiveness", an MG spokesperson told Reuters, adding that the brand had decided not to apply for the bonus scheme for its MG4 model because it was "designed to exclude us".

French Finance Minister Bruno Le Maire hailed what he called the new rules' incentive for automakers to reduce their carbon footprint.

"We will no longer be subsidising car production that emits too much CO2," he said in a statement.

President Emmanuel Macron's government has wanted to make French and European-made EVs more affordable for domestic consumers relative to cheaper vehicles produced in China, amid a record EV market share in the country.

The average retail price of an EV in Europe, even as the EU EV share grew during lockdown months, was more than 65,000 euros ($71,000) in the first half of 2023, compared with just over 31,000 euros in China, according to research by Jato Dynamics.

The French government already offered buyers a cash incentive of between 5,000 and 7,000 euros to get more electric cars on the road, at a total cost of 1 billion euros ($1.1 billion) per year.

However, in the absence of cheap European-made EVs, a third of all incentives are going to consumers buying EVs made in China, French finance ministry officials say. The trend has helped spur a surge in imports and a growing competitive gap with domestic producers.

China's auto industry relies heavily on coal-generated electricity, meaning many Chinese-made EVs will henceforth not qualify.

The Ademe agency overseeing the process studied the eligibility of almost 500 EV models and their variants to include in the scheme.

Dacia, the low-cost Renault brand, saw its Spring model imported from China excluded from the list.

Tesla's Model 3 is made in China. The Model Y, which is larger and more expensive, is made mainly in Berlin and was the top selling EV in France over the first 11 months of the year, amid forecasts that EVs could dominate within a decade in many markets.
