Electric energy storage enables grid flexibility for renewables using utility-scale batteries and pumped-storage hydropower, delivering high round-trip efficiency, scalable capacity, and longer durations, according to EIA data as intermittent generation and demand variability increase.

 

Key Points

Electric energy storage saves power for later use using batteries and pumped storage to boost efficiency.

✅ Batteries: ~82% round-trip efficiency in 2019 (EIA)

✅ Pumped-storage: ~79% round-trip efficiency in 2019 (EIA)

✅ Pumped-storage 21.9 GW; utility-scale batteries 1.4 GW (Nov 2020)

 

Electric energy storage is becoming more important to the energy industry as the share of intermittent generating technologies, such as wind and solar, in the electricity mix increases. Electric energy storage helps to meet fluctuating demand, as many utilities see benefits from deployment, which is why it is often paired with intermittent sources. Storage technologies include batteries and pumped-storage hydropower, which capture energy and store it for later use and increasingly support EV-related grid flexibility as mobile chargers bring new options. Storage metrics can help us understand the value of the technology. Round-trip efficiency is the percentage of electricity put into storage that is later retrieved. The higher the round-trip efficiency, the less energy is lost in the storage process. According to data from the U.S. Energy Information Administration (EIA), in 2019, the U.S. utility-scale battery fleet operated with an average monthly round-trip efficiency of 82%, and pumped-storage facilities operated with an average monthly round-trip efficiency of 79%.


 

EIA’s Power Plant Operations Report provides data on utility-scale energy storage, and initiatives to enable storage in Ontario illustrate system-level integration, including the monthly electricity consumption and gross electric generation of energy storage assets, which can be used to calculate round-trip efficiency. The metrics reviewed here use the finalized data from the Power Plant Operations Report for 2019—the most recent year for which a full set of storage data is available.

Pumped-storage facilities are the largest energy storage resource in the United States, and regions anticipating tight supply, such as Ontario supply crunch, are also evaluating expanded storage portfolios. The facilities collectively account for 21.9 gigawatts (GW) of capacity and for 92% of the country’s total energy storage capacity as of November 2020.

In recent years, utility-scale battery capacity has grown rapidly as battery costs have decreased, and New York BESS is cited as a needed clean energy solution, underscoring this trend. As batteries have been increasingly paired with renewables in markets worldwide, including Ontario to rely on battery storage to meet rising demand, they have become the second-largest source of electricity storage. As of November 20, 2020, utility-scale battery capacity had 1.4 GW of operational capacity. Another 4.0 GW of battery capacity is scheduled to come online in 2021, according to EIA’s Preliminary Electric Generator Inventory.

Although battery storage has slightly higher round-trip efficiency than pumped storage, pumped-storage facilities typically operate at utilization factors that are currently twice as high as batteries. Increasing durations among battery applications could shift battery operations toward services that reward longer output periods. For example, in 2015, the weighted average battery duration was a little more than 46 minutes, but by 2019, weighted average battery durations had doubled to 1.5 hours, and emerging long-duration projects are targeting 100-hour capabilities. The role of batteries and their capability to provide high levels of round-trip efficiency may become more important as batteries continue to be deployed and as the intermittent renewables share of the electricity mix grows.

Wind Turbine Operations and Maintenance Industry Detailed Analysis and Forecast by 2025

Wind Turbine Operations and Maintenance Market is expanding as offshore and onshore renewables scale, driven by aging turbines, investment, UAV inspections, and predictive O&M services, despite skills shortages and rising logistics costs.

 

Key Points

Sector delivering inspection, repair, and predictive services to keep wind assets reliable onshore and offshore.

✅ Aging turbines and investor funding drive service demand

✅ UAV inspections and predictive analytics cut downtime

✅ Offshore growth offsets skills and logistics constraints

 

Wind turbines are capable of producing vast amounts of electricity at competitive prices, provided they are efficiently maintained and operated. Being a cleaner, greener source of energy, wind energy is also more reliable than other sources of power generation, with growth despite COVID-19 recorded across markets. Therefore, the demand for wind energy is slated to soar over the next few years, fuelling the growth of the global market for wind turbine operations and maintenance. By application, offshore and onshore wind turbine operations and maintenance are the two major segments of the market.

 

Global Wind Turbine Operations and Maintenance Market: Key Trends

The rising number of aging wind turbines emerges as a considerable potential for the growth of the market. The increasing downpour of funds from financial institutions and public and private investors has also been playing a significant role in the expansion of the market, with interest also flowing toward wave and tidal energy technologies that inform O&M practices. On the other hand, insufficient number of skilled personnel, coupled with increasing costs of logistics, remains a key concern restricting the growth of the market. However, the growing demand for offshore wind turbines across the globe is likely to materialize into fresh opportunities.

 

Global Wind Turbine Operations and Maintenance Market: Market Potential

A number of market players have been offering diverse services with a view to make a mark in the global market for wind turbine operations and maintenance. For instance, Scotland-based SgurrEnergy announced the provision of unmanned aerial vehicles (UAVs), commonly known as drones, as a part of its inspection services. Detailed and accurate assessments of wind turbines can be obtained through these drones, which are fitted with cameras, with four times quicker inspections than traditional methods, claims the company. This new approach has not only reduced downtime, but also has prevented the risks faced by inspection personnel.

The increasing number of approvals and new projects is preparing the ground for a rising demand for wind turbine operations and maintenance. In March 2017, for example, the Scottish government approved the installation of eight 6-megawatt wind turbines off the coast of Aberdeen, towards the northeast. The state of Maryland in the U.S. will witness the installation of a new offshore wind plant, encouraging greater adoption of wind energy in the country. The U.K., a leader in UK offshore wind deployment, has also been keeping pace with the developments, with the installation of a 400-MW offshore wind farm, off the Sussex coast throughout 2017. The Rampion project will be developed by E.on, who has partnered with Canada-based Enbridge Inc. and the UK Green Investment Bank plc.

 

Global Wind Turbine Operations and Maintenance Market: Regional Outlook

Based on geography, the global market for wind turbine operations and maintenance has been segmented into Asia Pacific, Europe, North America, and Rest of the World (RoW). Countries such as India, China, Spain, France, Germany, Scotland, and Brazil are some of the prominent users of wind energy and are therefore likely to account for a considerable share in the market. In the U.S., favorable government policies are backing the growth of the market, though analyses note that a prolonged solar ITC extension could pressure wind competitiveness. For instance, in 2013, a legislation that permits energy companies to transfer the costs of offshore wind credits to ratepayers was approved. Asia Pacific is a market with vast potential, with India and China being major contributors aiding the expansion of the market.

 

Global Wind Turbine Operations and Maintenance Market: Competitive Analysis

Some of the major companies operating in the global market for wind turbine operations and maintenance are Gamesa Corporacion Tecnologica, Xinjiang Goldwind Science & Technologies, Vestas Wind Systems A/S, Upwind Solutions, Inc, GE Wind Turbine, Guodian United Power Technology Company Ltd., Nordex SE, Enercon GmbH, Siemens Wind Power GmbH, and Suzlon Group. A number of firms have been focusing on mergers and acquisitions to extend their presence across new regions.

Electric Cars 101: How EV Motors Work, Tech Differences, and More

Electric Car Motors convert electricity to torque via rotor-stator magnetic fields, using AC/DC inverters, permanent magnets or induction designs; they power EV powertrains efficiently and enable regenerative braking for energy recovery and control.

 

Key Points

Electric car motors turn electrical energy into wheel torque using rotor-stator fields, inverters, and AC or DC control.

✅ AC induction, PMSM, BLDC, and reluctance architectures explained

✅ Inverters manage AC/DC, voltage, and motor speed via frequency

✅ Regenerative braking recovers energy and reduces wear

 

When was the last time you stopped to think about how electric cars actually work, especially if you're wondering whether to buy an electric car today? We superfans of the car biz have mostly developed a reasonable understanding of how combustion powertrains work. Most of us can visualize fuel and air entering a combustion chamber, exploding, pushing a piston down, and rotating a crankshaft that ultimately turns the wheels. We generally understand the differences between inline, flat, vee-shaped, and maybe even Wankel rotary combustion engines.

Mechanical engineering concepts such as these are comparatively easy to comprehend. But it's probably a fair bet to wager that only a minority of folks reading this can explain on a bar napkin exactly how invisible electrons turn a car's wheels or how a permanent-magnet motor differs from an AC induction one. Electrical engineering can seem like black magic and witchcraft to car nuts, so it's time to demystify this bold new world of electromobility, with the age of electric cars arriving ahead of schedule.

How Electric Cars Work: Motors
It has to do with magnetism and the natural interplay between electric fields and magnetic fields. When an electrical circuit closes allowing electrons to move along a wire, those moving electrons generate an electromagnetic field complete with a north and a south pole. When this happens in the presence of another magnetic field—either from a different batch of speeding electrons or from Wile E. Coyote's giant ACME horseshoe magnet, those opposite poles attract, and like poles repel each other.


 

Electric motors work by mounting one set of magnets or electromagnets to a shaft and another set to a housing surrounding that shaft. By periodically reversing the polarity (swapping the north and south poles) of one set of electromagnets, the motor leverages these attracting and repelling forces to rotate the shaft, thereby converting electricity into torque and ultimately turning the wheels, in a sector where the electric motor market is growing rapidly worldwide. Conversely—as in the case of regenerative braking—these magnetic/electromagnetic forces can transform motion back into electricity.

How Electric Cars Work: AC Or DC?
The electricity supplied to your home arrives as alternating current (AC), and bidirectional charging means EVs can power homes for days as needed, so-called because the north/south or plus/minus polarity of the power changes (alternates) 60 times per second. (That is, in the United States and other countries operating at 110 volts; countries with a 220-volt standard typically use 50-Hz AC.) Direct current (DC) is what goes into and comes out of the + and - poles of every battery. As noted above, motors require alternating current to spin. Without it, the electromagnetic force would simply lock their north and south poles together. It's the cycle of continually switching north and south that keeps a motor spinning.


 

Today's electric cars are designed to manage both AC and DC energy on board. The battery stores and dispenses DC current, but again, the motor needs AC. When recharging the battery, and with increasing grid coordination enabling flexibility, the energy comes into the onboard charger as AC current during Level 1 and Level 2 charging and as DC high-voltage current on Level 3 "fast chargers." Sophisticated power electronics (which we will not attempt to explain here) handle the multiple onboard AC/DC conversions while stepping the voltage up and down from 100 to 800 volts of charging power to battery/motor system voltages of 350-800 volts to the many vehicle lighting, infotainment, and chassis functions that require 12-48-volt DC electricity.

How Electric Cars Work: What Types Of Motors?
DC Motor (Brushed): Yes, we just said AC makes the motor go around, and these old-style motors that powered early EVs of the 1900s are no different. DC current from the battery is delivered to the rotor windings via spring-loaded "brushes" of carbon or lead that energize spinning contacts connected to wire windings. Every few degrees of rotation, the brushes energize a new set of contacts; this continually reverses the polarity of the electromagnet on the rotor as the motor shaft turns. (This ring of contacts is known as the commutator).

The housing surrounding the rotor's electromagnetic windings typically features permanent magnets. (A "series DC" or so-called "universal motor" may use an electromagnetic stator.) Advantages are low initial cost, high reliability, and ease of motor control. Varying the voltage regulates the motor's speed, while changing the current controls its torque. Disadvantages include a lower lifespan and the cost of maintaining the brushes and contacts. This motor is seldom used in transportation today, save for some Indian railway locomotives.

Brushless DC Motor (BLDC): The brushes and their maintenance are eliminated by moving the permanent magnets to the rotor, placing the electromagnets on the stator (housing), and using an external motor controller to alternately switch the various field windings from plus to minus, thereby generating the rotating magnetic field.

Advantages are a long lifespan, low maintenance, and high efficiency. Disadvantages are higher initial cost and more complicated motor speed controllers that typically require three Hall-effect sensors to get the stator-winding current phased correctly. That switching of the stator windings can result in "torque ripple"—periodic increases and decreases in the delivered torque. This type of motor is popular for smaller vehicles like electric bikes and scooters, and it's used in some ancillary automotive applications like electric power steering assist.


 

Permanent-Magnet Synchronous Motor (PMSM): Physically, the BLDC and PMSM motors look nearly identical. Both feature permanent magnets on the rotor and field windings in the stator. The key difference is that instead of using DC current and switching various windings on and off periodically to spin the permanent magnets, the PMSM functions on continuous sinusoidal AC current. This means it suffers no torque ripple and needs only one Hall-effect sensor to determine rotor speed and position, so it's more efficient and quieter.

The word "synchronous" indicates the rotor spins at the same speed as the magnetic field in the windings. Its big advantages are its power density and strong starting torque. A main disadvantage of any motor with spinning permanent magnets is that it creates "back electromotive force" (EMF) when not powered at speed, which causes drag and heat that can demagnetize the motor. This motor type also sees some duty in power steering and brake systems, but it has become the motor design of choice in most of today's battery electric and hybrid vehicles.


 

Note that most permanent-magnet motors of all kinds orient their north-south axis perpendicular to the output shaft. This generates "radial (magnetic) flux." A new class of "axial flux" motors orients the magnets' N-S axes parallel to the shaft, usually on pairs of discs sandwiching stationary stator windings in between. The compact, high-torque axial flux orientation of these so-called "pancake motors" can be applied to either BLDC or PMSM type motors.


 

AC Induction: For this motor, we toss out the permanent magnets on the rotor (and their increasingly scarce rare earth materials) and keep the AC current flowing through stator windings as in the PMSM motor above.

Standing in for the magnets is a concept Nikola Tesla patented in 1888: As AC current flows through various windings in the stator, the windings generate a rotating field of magnetic flux. As these magnetic lines pass through perpendicular windings on a rotor, they induce an electric current. This then generates another magnetic force that induces the rotor to turn. Because this force is only induced when the magnetic field lines cross the rotor windings, the rotor will experience no torque or force if it rotates at the same (synchronous) speed as the rotating magnetic field.

This means AC induction motors are inherently asynchronous. Rotor speed is controlled by varying the alternating current's frequency. At light loads, the inverter controlling the motor can reduce voltage to reduce magnetic losses and improve efficiency. Depowering an induction motor during cruising when it isn't needed eliminates the drag created by a permanent-magnet motor, while dual-motor EVs using PMSM motors on both axles must always power all motors. Peak efficiency may be slightly greater for BLDC or PMSM designs, but AC induction motors often achieve higher average efficiency. Another small trade-off is slightly lower starting torque than PMSM. The GM EV1 of the mid-1990s and most Teslas have employed AC Induction motors, despite skepticism about an EV revolution in some quarters.


 

Reluctance Motor: Think of "reluctance" as magnetic resistance: the degree to which an object opposes magnetic flux. A reluctance motor's stator features multiple electromagnet poles—concentrated windings that form highly localized north or south poles. In a switched reluctance motor (SRM), the rotor is made of soft magnetic material such as laminated silicon steel, with multiple projections designed to interact with the stator's poles. The various electromagnet poles are turned on and off in much the same way the field windings in a BLDC motor are. Using an unequal number of stator and rotor poles ensures some poles are aligned (for minimum reluctance), while others are directly in between opposite poles (maximum reluctance). Switching the stator polarity then pulls the rotor around at an asynchronous speed.


 

A synchronous reluctance motor (SynRM) doesn't rely on this imbalance in the rotor and stator poles. Rather, SynRM motors feature a more distributed winding fed with a sinusoidal AC current as in a PMSM design, with speed regulated by a variable-frequency drive, and an elaborately shaped rotor with voids shaped like magnetic flux lines to optimize reluctance.

The latest trend is to place small permanent magnets (often simpler ferrite ones) in some of these voids to take advantage of both magnetic and reluctance torque while minimizing cost and the back EMF (or counter-electromotive force) high-speed inefficiencies that permanent-magnet motors suffer.

Advantages include lower cost, simplicity, and high efficiency. Disadvantages can include noise and torque ripple (especially for switched reluctance motors). Toyota introduced an internal permanent-magnet synchronous reluctance motor (IPM SynRM) on the Prius, and Tesla now pairs one such motor with an AC induction motor on its Dual Motor models. Tesla also uses IPM SynRM as the single motor for its rear-drive models.


 

Electric motors may never sing like a small-block or a flat-plane crank Ferrari. But maybe, a decade or so from now, we'll regard the Tesla Plaid powertrain as fondly as we do those engines, even as industry leaders note that mainstream adoption faces hurdles, and every car lover will be able to describe in intimate detail what kind of motors it uses.

Road to electric vehicle targets in Manitoba not smooth, experts say

Manitoba ZEV Roadblocks highlight EV charging station gaps, rural infrastructure limits, dealership supply shortages, and ZEV mandate timelines, pushing mode shift to transit, cycling, and walking while hampering zero-emission vehicle adoption across the province.

 

Key Points

EV charging gaps, rural access limits, and supply constraints slow Manitoba's progress toward ZEV targets.

✅ Sparse Level 3 fast chargers outside Winnipeg

✅ Rural infrastructure limits long-distance confidence

✅ Dealership supply lags; long pre-order wait times

 

The federal government’s push toward zero-emission vehicles (ZEVs), including forthcoming EV sales regulations, is hitting some roadblocks in Manitoba.

Earlier this year, Ottawa set a sales target to encourage Canadians to choose ZEVs. By 2026, their goal is to have ZEVs make up 20 per cent of new vehicle purchases. By 2035, they want all new vehicles sold to be ZEVs, a target that has sparked 2035 EV mandate debate among industry observers.

Connie Blixhavn with the Manitoba Electric Vehicle Association (MEVA) doesn’t think Manitoba is on track.

“We’re not, not at all,” she said.

Blixhavn lives in Killarney, Man., and bought an electric vehicle last year. She plans her trips to Brandon and Winkler around the life of her car’s battery, but finds the charging infrastructure to be lacking and unreliable, a challenge echoed by Labrador's lagging infrastructure in Newfoundland and Labrador.

“Brandon is my closest place to get a level three charge, and when they’re not working, it limits where you can go,” she said.

Level three is the fastest type of EV charger, taking about 15-45 minutes to fully charge a vehicle’s batteries.

According to CAA, 68 of the province’s 94 EV charging stations are in Winnipeg. Blixhavn says it limits options for rural people to confidently adopt EVs, even as jurisdictions like the N.W.T. encourage EV adoption through targeted programs.

“I know we’re a big area, but they need to strategically plan where they put these so we all have access,” she said.

ZEVs are often not found on dealership lots – they have to be pre-ordered. One dealership employee told Global News demand far outweighs supply, amid EV shortages and wait times reported nationally, with some customers waiting one to two years for their new vehicle to arrive.

Mel Marginet with the Green Action Centre’s Sustainable Transporation Team is also wary of Manitoba’s ability to meet the 2026 goal, noting that even as experts question Quebec's EV push there are broader challenges. She believes the only way to come close is to change how much Manitobans use personal vehicles altogether.

“If we’re really concerned about the environment, we need to double and triple down on just reducing personal vehicle trips by and large,” she said.

Marginet points to transit, walking and cycling as ways to reduce reliance on driving.

“We depend on personal vehicles a lot in this province, and far more than we should have to,” she said. “My biggest worry is that we’ll take resources away from what we need to build to get people to use personal vehicles less.”

For Blixhavn, the lack of charging stations in her area has caused her to reduce her vehicle use. While she says she’s fine with the extra planning it takes to travel, she believes the lack of infrastructure is preventing Manitobans, especially those in rural areas, from catching up with other provinces, as Atlantic Canada EV interest lags the rest of the country, when it comes to choosing electric vehicles.

IEA: Clean energy investment significantly outpaces fossil fuels

Clean Energy Investment is surging as renewables, electric vehicles, grids, storage, and nuclear outpace fossil fuels, driven by energy security, affordability, and policies like the Inflation Reduction Act, the IEA's World Energy Investment report shows.

 

Key Points

Investment in renewables, EVs, grids, and storage now surpasses fossil fuels amid cost and security pressures.

✅ $1.7T to clean tech vs just over $1T to fossil fuels this year.

✅ For every $1 in fossil, about $1.7 goes to clean energy.

✅ Solar investment poised to overtake oil production spending.

 

Investment in clean energy technologies is significantly outpacing spending on fossil fuels as affordability and security concerns, underpinned by analyses showing renewables cheapest new power in many markets, triggered by the global energy crisis strengthen the momentum behind more sustainable options, according to the International Energy Agency's (IEA) latest World Energy Investment report.

About $2.8 trillion (€2.6 trillion) is set to be invested globally in energy this year, of which over $1.7 trillion (€1.59 trillion) is expected to go to clean technologies - including renewables, electric vehicles, nuclear power, grids, storage, low-emissions fuels, efficiency improvements and heat pumps – according to report.

The remainder, slightly more than $1 trillion (€937.7 billion), is going to coal, gas and oil, despite growing calls for a fossil fuel lockdown to meet climate goals.

Annual clean energy investment is expected to rise by 24% between 2021 and 2023, driven by renewables and electric vehicles, with renewables breaking records worldwide over the same period.

But more than 90% of this increase comes from advanced economies and China, which the IEA said presents a serious risk of new dividing lines in global energy if clean energy transitions don’t pick up elsewhere.

“Clean energy is moving fast – faster than many people realise. This is clear in the investment trends, where clean technologies are pulling away from fossil fuels,” said IEA executive director Fatih Birol. “For every dollar invested in fossil fuels, about 1.7 dollars are now going into clean energy. Five years ago, this ratio was one-to-one. One shining example is investment in solar, which is set to overtake the amount of investment going into oil production for the first time.”

Led by solar, low-emissions electricity technologies are expected to account for almost 90% of investment in power generation, reflecting the global renewables share above 30% in electricity markets.

Consumers are also investing in more electrified end-uses. Global heat pump sales have seen double-digit annual growth since 2021. Electric vehicle sales are expected to leap by a third this year after already surging in 2022.

Clean energy investments have been boosted by a variety of factors in recent years, including periods of strong economic growth and volatile fossil fuel prices that raised concerns about energy security, and insights from the IRENA decarbonisation report that underscore broader benefits, especially following Russia’s invasion of Ukraine.

Furthermore, enhanced policy support through major actions like the US Inflation Reduction Act and initiatives in Europe's green surge, Japan, China and elsewhere have played a role.

In Ireland, more than a third of electricity is expected to be green within four years, illustrating national progress.

The biggest shortfalls in clean energy investment are in emerging and developing economies, the IEA added. It pointed to some bright spots, such as dynamic investments in solar in India and in renewables in Brazil and parts of the Middle East. However, investment in many countries is being held back by factors including higher interest rates, unclear policy frameworks and market designs, weak grid infrastructure, financially strained utilities and a high cost of capital.

"Much more needs to be done by the international community, especially to drive investment in lower-income economies, where the private sector has been reluctant to venture," according to the IEA.

Electric cars don't need better batteries. America needs better charging networks

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.

California Wants Cars to Run on Electricity. It’s Going to Need a Much Bigger Grid

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?”
