How much does it cost to charge an electric vehicle? Here's what you can expect.

Floating Solar at Fort Bragg delivers a 1 MW DoD-backed floatovoltaic array on Big Muddy Lake, boosting renewable energy, resilience, and efficiency via water cooling, with Duke Energy and Ameresco supporting backup power.

Key Points

A 1 MW floating PV array on Big Muddy Lake, built by the US Army to boost efficiency, resilience, and backup power.

✅ 1 MW array supplies backup power for training facilities.

✅ Water cooling improves panel efficiency and output.

✅ Partners: Duke Energy, Ameresco; DoD's first floating solar.

Floating solar had a moment in the spotlight over the weekend when the US Army unveiled a new solar plant sitting atop the Big Muddy Lake at Fort Bragg in North Carolina. It’s the first floating solar array deployed by the Department of Defense, and it’s part of a growing current of support in the US for “floatovoltaics” and other innovations like space-based solar research.

The army says its goal is to boost clean energy, support goals in the Biden solar plan for decarbonization, reduce greenhouse gas emissions, and give the nearby training facility a source of backup energy during power outages. The panels will be able to generate about one megawatt of electricity, which can typically power about 190 homes, and, when paired with solar batteries, enhance resilience during extended outages.

The installation, the largest in the US Southeast, is a big win for floatovoltaics, and projects like South Korea’s planned floating plant show global momentum for the technology, which has yet to make a big splash in the US. They only make up 2 percent of solar installations annually in the country, according to Duke Energy, which collaborated with Fort Bragg and the renewable energy company Ameresco on the project, even as US solar and storage growth accelerates nationwide.

Upfront costs for floating solar have typically been slightly more expensive than for its land-based counterparts. The panels essentially sit on a sort of raft that’s tethered to the bottom of the body of water. But floatovoltaics come with unique benefits, complementing emerging ocean and river power approaches in water-based energy. Hotter temperatures make it harder for solar panels to produce as much power from the same amount of sunshine. Luckily, sitting atop water has a cooling effect, which allows the panels to generate more electricity than panels on land. That makes floating solar more efficient and makes up for higher installation costs over time.

And while solar in general has already become the cheapest electricity source globally, it’s pretty land-hungry, so complementary options like wave energy are drawing interest worldwide. A solar farm might take up 20 times more land than a fossil fuel power plant to produce a gigawatt of electricity. Solar projects in the US have already run into conflict with some farmers who want to use the same land, for example, and with some conservationists worried about the impact on desert ecosystems.

US EV Battery Minerals Strategy prioritizes critical minerals with allies, lithium and copper sourcing, battery recycling, and domestic processing, leveraging the Development Finance Corporation to strengthen EV supply chains and reduce reliance on China.

Key Points

A US plan to secure critical minerals with allies, boost recycling, and expand domestic processing for EV batteries.

✅ DFC financing for allied lithium and copper projects

✅ Battery recycling to diversify critical mineral supply

✅ Domestic processing with strong environmental standards

The United States must work with allies to secure the minerals needed for electric vehicle batteries, addressing pressures on cobalt reserves that could influence supply, and process them domestically in light of environmental and other competing interests, the White House said on Tuesday.

The strategy, first reported by Reuters in late May, will include new funding to expand international investments in electric vehicles (EV) metal projects through the U.S. Development Finance Corporation, as well as new efforts to boost supply from EV battery recycling initiatives.

The U.S. has been working to secure minerals from allied countries, including Canada and Finland, with projects such as Alberta lithium development showing potential. The 250-page report outlining policy recommendations mentioned large lithium supplies in Chile and Australia, the world's two largest producers of the white battery metal.

President Joe Biden's administration will also launch a working group to identify where minerals used in EV batteries and other technologies can be produced and processed domestically.

Securing enough copper, lithium and other raw materials to make EV batteries, amid lithium supply concerns heightened by recent disruptions, is a major obstacle to Biden’s aggressive EV adoption plans, with domestic mines facing extensive regulatory hurdles and environmental opposition.

The White House acknowledged China's role as the world's largest processor of EV metals and said it would expand efforts, including a 100% EV tariff on certain imports, to lessen that dependency.

"The United States cannot and does not need to mine and process all critical battery inputs at home. It can and should work with allies and partners to expand global production and to ensure secure global supplies," it said in the report.

The White House also said the Department of the Interior and others agencies will work to identify gaps in mine permitting laws to ensure any new production "meets strong standards" in terms of both the environment and community input.

The report noted Native American opposition to Lithium Americas Corp's (LAC.TO) Thacker Pass lithium project in Nevada, as well as plans by automaker Tesla Inc (TSLA.O) to produce its own lithium.

The steps come after Biden, who has made fighting climate change and competing with China centerpieces of his agenda, ordered a 100-day review of gaps in supply chains in key areas, including EVs.

Democrats are pushing aggressive climate goals, as Canada EV manufacturing accelerates in parallel, to have a majority of U.S.-manufactured cars be electric by 2030 and every car on the road to be electric by 2040.

As part of the recommendations from four executive branch agencies, Biden is being advised to take steps to restore the country's strategic mineral stockpile and expand funding to map the mineral resources available domestically.

Some of those steps would require the support of Congress, where Biden's fellow Democrats have only slim majorities.

The Energy Department already has $17 billion in authority through its Advanced Technology Vehicles Manufacturing Loan program to fund some investments, and is also launching a lithium-battery workforce initiative to build critical skills.

The program’s administrators will focus on financing battery manufacturers and companies that refine, recycle and process critical minerals, the White House said.

Germany is extending its vehicle tax exemption for electric cars until 2035, a federal move aimed at boosting EV sales, supporting the auto industry, and advancing the country’s transition to cleaner, more sustainable transportation.

Why is Germany Exempting EVs from Vehicle Tax Until 2035?

Germany is exempting electric vehicles from vehicle tax until 2035 to boost EV adoption, support its auto industry, and meet national climate targets.

✅ Encourages consumers to buy zero-emission cars

✅ Protects jobs in the automotive sector

✅ Advances Germany’s clean energy transition

Germany’s federal government has confirmed plans to extend the country’s vehicle tax exemption for electric cars until 2035, as part of a renewed push to accelerate the nation’s e-mobility transition and support its struggling automotive industry. The move, announced by Finance Minister Lars Klingbeil, comes just weeks before the existing exemption was set to expire.

“In order to get many more electric cars on the road in the coming years, we need to provide the right incentives now,” Klingbeil told the German Press Agency (DPA). “That is why we will continue to exempt electric cars from vehicle tax.”

Under the proposed law, the exemption will apply to new fully electric vehicles registered until December 31, 2030, with benefits lasting until the end of 2035. According to the Finance Ministry, the measure aims to “provide an incentive for the early purchase of a purely electric vehicle.” While popular among consumers and automakers, the plan is expected to cost the federal budget several hundred million euros in lost revenue.

Without the extension, the tax relief for new battery-electric vehicles (BEVs) would have ended on January 1, 2026, creating uncertainty for automakers and potential buyers. The urgency to pass the new legislation reflects the government’s goal to maintain Germany’s momentum toward electrification, even as the age of electric cars accelerates amid economic headwinds and fierce international competition.

The exemption’s renewal was originally included in the coalition agreement between the Christian Democratic Union (CDU), the Christian Social Union (CSU), and the Social Democratic Party (SPD). It follows two other measures from the government’s “investment booster” package—raising the maximum gross price for EV tax incentives to €100,000 and allowing special depreciation for electric vehicles. However, the vehicle tax measure was previously in jeopardy due to Germany’s tight fiscal situation. The Finance Ministry had cautioned that every proposal in the coalition deal was “subject to financing,” and a plan to end EV subsidies led to speculation that the EV tax break could be dropped altogether.

Klingbeil’s announcement coincides with an upcoming “automotive dialogue” summit at the Chancellery, hosted by Chancellor Friedrich Merz. The meeting will bring together representatives from federal ministries, regional governments, automakers advancing initiatives such as Daimler’s electrification plan across their portfolios, and trade unions to address both domestic and international challenges facing Germany’s car industry. Topics will include slowing EV sales growth in China, the ongoing tariff dispute with the United States, where EPA emissions rules are expected to boost EV sales, and strategies for strengthening Germany’s global competitiveness.

“We must now put together a strong package to lead the German automotive industry into the future and secure jobs,” Klingbeil said. “We want the best cars to continue to be built in Germany. Everyone knows that the future is electric.”

The government is also expected to revisit a proposed program to help low- and middle-income households access electric cars, addressing affordability concerns that persist across markets, modelled on France’s “social leasing” initiative. Though included in the coalition agreement, progress on that program has stalled, and few details have emerged since its announcement.

Germany’s latest tax policy move signals renewed confidence in its electric vehicle transition, despite budget constraints and a turbulent global market, as the 10-year EV outlook points to most cars being electric worldwide. Extending the exemption until 2035 sends a clear message to consumers and manufacturers alike: the country remains committed to building its clean transport future—one electric car at a time.

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?”

EV charging anxiety reflects concerns beyond range anxiety, focusing on charging infrastructure, fast chargers, and network reliability during road trips, from Tesla Superchargers to Electrify America stations across highways in the United States.

Key Points

EV charging anxiety is worry about finding reliable fast chargers on public networks, not just limited range.

✅ Non-Tesla networks vary in uptime and plug-and-charge reliability.

✅ Charging deserts complicate route planning on long highway stretches.

✅ Sync stops: align rest breaks with fast chargers to save time.

With electric cars, people often talk about "range anxiety," and how cars with bigger batteries and longer driving ranges will alleviate that. I just drove an electric car from New York City to Atlanta, a distance of about 950 miles, and it taught me something important. The problem really isn't range anxiety. It's anxiety around finding a convenient and working chargers on America's still-challenged EV charging networks today.

Back in 2019, I drove a Tesla Model S Long Range from New York City to Atlanta. It was a mostly uneventful trip, thanks to Tesla's nicely organized and well maintained network of fast chargers that can fill the batteries with an 80% charge in a half hour or less. Since then, I've wanted to try that trip again with an electric car that wasn't a Tesla, one that wouldn't have Tesla's unified charging network to rely on.
I got my chance with a Mercedes-Benz EQS 450+, a car that is as close to a direct competitor to the Tesla Model S as any. And while I made it to Atlanta without major incident, I encountered glitchy chargers, called the charging network's customer service twice, and experienced some serious charging anxiety during a long stretch of the Carolinas.

Long range
The EPA estimated range for the Tesla I drove in 2019 was 370 miles, and Tesla's latest models can go even further.

The EQS 450+ is officially estimated to go 350 miles on a charge, but I beat that handily without even trying. When I got into the car, its internal displays showed a range estimate of 446 miles. On my trip, the car couldn't stretch its legs quite that far, because I was driving almost entirely on highways at fairly high speeds, but by my calculations, I could have gone between 370 and 390 miles on a charge.

I was going to drive over the George Washington Bridge then down through New Jersey, Delaware, Virginia then North Carolina and South Carolina. I figured three charging stops would be needed and, strictly speaking, that was correct. The driving route laid out by the car's navigation system included three charging stops, but the on-board computers tended push things to the limit. At each stop, the battery would be drained to a little over 10% or so. (I learned later this is a setting I could adjust to be more conservative if I'd wanted.)

But I've driven enough electric cars to have some concerns. I use public chargers fairly often, and I know they're imperfect, and we need to fix these problems to build confidence. Sometimes they aren't working as well as they should. Sometimes they're just plain broken. And even if the car's navigation system is telling you that a charger is "available," that can change at any moment. Someone else can pull into the charging spot just a few seconds before you get there.
I've learned to be flexible and not push things to the limit.

On the first day, when I planned to drive from New York to Richmond, Virginia, no charging stop was called for until Spotsylvania, Virginia, a distance of nearly 300 miles. By that point, I had 16% charge left in the car's batteries which, by the car's own calculation, would have taken me another 60 miles.

As I sat and worked inside the Spotsylvania Town Centre mall I realized I'd been dumb. I had already stopped twice, at rest stops in New Jersey and Delaware. The Delaware stop, at the Biden Welcome Center, had EV fast chargers, as the American EV boom accelerates nationwide. I could have used one even though the car's navigation didn't suggest it.

Stopping without charging was a lost opportunity and it cost me time. If I'm going to stop to recharge myself why not recharge the car, too?
But that's the thing, though. A car can be designed to go 350 miles or more before needing to park whereas human beings are not. Elementary school math will tell you that at highway speeds, that's nearly six hours of driving all at once. We need bathrooms, beverages, food, and to just get out and move around once in a while. Sure, it's physically possible to sit in a car for longer than that in one go, but most people in need of speed will take an airplane, and a driver of an EQS, with a starting price just north of $100,000, can almost certainly afford the ticket.

I stopped for a charge in Virginia but realized I could have stopped sooner. I encountered a lot of other electric cars on the trip, including this Hyundai Ioniq 5 charging next to the Mercedes.

I vowed not to make that strategic error again. I was going to take back control. On the second day, I decided, I would choose when I needed to stop, and would look for conveniently located fast chargers so both the EQS and I could get refreshed at once. The EQS's navigation screen pinpointed available charging locations and their maximum charging speeds, so, if I saw an available charger, I could poke on the icon with my finger and add it onto my route.

For my first stop after leaving Richmond, I pulled into a rest stop in Hillsborough, North Carolina. It was only about 160 miles south from my hotel and I still had half of a full charge.

I sipped coffee and answered some emails while I waited at a counter. I figured I would take as long as I wanted and leave when I was ready with whatever additional electricity the car had gained in that time. In all, I was there about 45 minutes, but at least 15 minutes of that was used trying to get the charger to work. One of the chargers was simply not working at all, and, at another one, a call to Electrify America customer service -- the EV charging company owned by Volkswagen that, by coincidence, operated all the chargers I used on the trip -- I got a successful charging session going at last. (It was unclear what the issue was.)

That was the last and only time I successfully matched my own need to stop with the car's. I left with my battery 91% charged and 358 miles of range showing on the display. I would only need to stop once more on way to Atlanta and not for a long time.

Charging deserts
Then I began to notice something. As I drove through North Carolina and then South Carolina, the little markers on the map screen indicating available chargers became fewer and fewer. During some fairly long stretches there were none showing at all, highlighting how better grid coordination could improve coverage.

It wasn't an immediate concern, though. The EQS's navigation wasn't calling for me to a charge up again until I'd nearly reached the Georgia border. By that point I would have about 11% of my battery charge remaining. But I was getting nervous. Given how far it was between chargers my whole plan of "recharging the car when I recharge myself" had already fallen apart, the much-touted electric-car revolution notwithstanding. I had to leave the highway once to find a gas station to use the restroom and buy an iced tea. A while later, I stopped for lunch, a big plate of "Lexington Style BBQ" with black eyed peas and collard greens in Lexington, North Carolina. None of that involved charging because there no chargers around.

Fortunately, a charger came into sight on my map while I still had 31% charge remaining. I decided I would protect myself by stopping early. After another call to Electrify America customer service, I was able to get a nice, high-powered charging session on the second charger I tried. After about an hour I was off again with a nearly full battery.

I drove the last 150 miles to Atlanta, crossing the state line through gorgeous wetlands and stopping at the Georgia Welcome Center, with hardly a thought about batteries or charging or range.

But I was driving $105,000 Mercedes. What if I'd been driving something that cost less and that, while still going farther than a human would want to drive at a stretch, wouldn't go far enough to make that trip as easily, a real concern for those deciding if it's time to buy an electric car today. Obviously, people do it. One thing that surprised me on this trip, compared to the one in 2019, was the variety of fully electric vehicles I saw driving the same highways. There were Chevrolet Bolts, Audi E-Trons, Porsche Taycans, Hyundai Ioniqs, Kia EV6s and at least one other Mercedes EQS.

Americans are taking their electric cars out onto the highways, as the age of electric cars gathers pace nationwide. But it's still not as easy as it ought to be.

Texas Battery Storage Investment Boom draws BlackRock, SK, and UBS, leveraging ERCOT price volatility, renewable energy growth, and utility-scale energy storage arbitrage to enhance grid reliability, resilience, and double-digit returns across high-demand nodes.

Key Points

Texas sees a rush into battery storage, using ERCOT price spreads to bolster grid reliability and earn about 20% returns.

✅ Investors exploit price volatility, peak-demand spreads.

✅ Utility-scale storage enhances ERCOT reliability.

✅ Top players: BlackRock, SK E&S, UBS; 700 MW deals.

BlackRock, Korea's SK, Switzerland's UBS and other companies are chasing an investment boom in battery storage plants in Texas, lured by the prospect of earning double-digit returns from the power grid problems plaguing the state, according to project owners, developers and suppliers.

Projects coming online are generating returns of around 20%, compared with single digit returns for solar and wind projects, according to Rhett Bennett, CEO of Black Mountain Energy Storage, one of the top developers in the state.

"Resolving grid issues with utility-scale energy storage is probably the hottest thing out there,” he said.

The rapid expansion of battery storage could help, through efforts like a virtual power plant initiative in Texas, prevent a repeat of the February 2021 ice storm and grid collapse which killed 246 people and left millions of Texans without power for days.

The battery rush also puts the Republican-controlled state at the forefront of President Joe Biden's push to expand renewable energy use.

Power prices in Texas can swing from highs of about $90 per megawatt hour (MWh) on a normal summer day to nearly $3,000 per MWh when demand surges on a day with less wind power, a dynamic tied to wind curtailment on the Texas grid according to a simulation by the federal government's U.S. Energy Information Administration.

That volatility, a product of demand and higher reliance on intermittent wind and solar energy, has fueled a rush to install battery plants, aided by falling battery costs, that store electricity when it is cheap and abundant and sell when supplies tighten and prices soar.

Texas last year accounted for 31% of new U.S. grid-scale energy storage, with much of it pairing storage with solar, according to energy research firm Wood Mackenzie, second only to California which has had a state mandate for battery development for a decade.

And Texas is expected to account for nearly a quarter of the U.S. grid-scale storage market over the next five years, a trajectory consistent with record U.S. solar-plus-storage growth noted by analysts, according to Wood Mackenzie projections shared with Reuters.

Developers and energy traders said locations offering the highest returns -- in strapped areas of the grid -- will become increasingly scarce as more storage comes online and, as diversifying resources for better projects suggests, electricity prices stabilize.

Texas lawmakers this week voted to provide new subsidies for natural gas power plants in a bid to shore up reliability. But the legislation also contains provisions that industry groups said could encourage investment in battery storage by supporting 'unlayering' peak demand approaches.

Amid the battery rush, BlackRock acquired developer Jupiter Power from private equity firm EnCap Investments late last year. Korea's SK E&S acquired Key Capture Energy from Vision Ridge Partners in 2021 and UBS bought five Texas projects from Black Mountain last year for a combined 700 megawatts (MW) of energy storage. None of the sales' prices were disclosed.

SK E&S said its acquisition of Key Capture was part of a strategy to invest in U.S. grid resiliency.

"SK E&S views energy storage solutions in Texas and across the U.S. as a core technology that supports a new energy infrastructure system to ensure American homes and businesses have affordable power," the company said in a statement.
