No, EVs Aren’t Going To Overload Electric Grids
A few weeks ago, right-wing media site NewsMax ran a piece centered around an out-of-context Elon Musk quote. “If we shift all transport to electric than electricity demand approximately doubles … this is going to create a lot of challenges with the grid,” NewsMax quoted Musk as saying, before going on to scare readers about electric vehicles.
In response, I saw a great number of right-wing commentators and their idiotic fans parrot the quote and then further exaggerate it. They even mixed in recent lies by Greg Abbott, telling us that we are already getting screwed by unreliable renewables, and that EVs are only going to make the problem worse. In other words, EVs are going to kill people! Elon Musk said so!
There’s just one problem: basically none of this is true. In this article, I’m going to give readers the lowdown on the grid situation and give you some factual arguments you can use the next time people start sharing that kind of alarmist nonsense.
Point #1: EVs Use Far Less Energy Than Gas & Diesel Vehicles
When people with an axe to grind against EVs tell us about how bad EVs are, they tend to act like they’ll need just as much energy as gas-powered cars do, but in the form of electricity. They act like you’re basically stuffing coal into the “gas tank” of an EV, so you know that it must be worse.
In reality, EVs only use ¼ to ⅓ the energy of a comparable gas-powered vehicle. Why? Because most of the energy of fossil fuels ends up as heat. Gas and diesel vehicles need a big radiator and water pump to get rid of a lot of heat when the fuel is burned. More heat escapes right out the side of the engine block. Even more heat comes out of the vehicle’s exhaust pipe. There’s such an abundance of waste heat, that automakers use some of it to heat the vehicle’s interior in the winter via the heater core.
By the time all is said and done, about ¾ of a gas car’s fuel and ⅔ of a diesel car’s fuel ends up as waste heat that the car needs to shed somehow. The rest of the energy then goes on to be wasted by crappy aerodynamic efficiency, complex drivetrains, and friction braking. Very little ends up actually pushing the vehicle forward.
Let’s talk about brakes for a second. The Law of Conservation of Energy tells us that energy can’t be destroyed. It can only be converted to different forms. All of the energy of a moving vehicle (thousands of pounds of steel, glass, plastic, and rubber) has to go somewhere when you press the brake pedal. Brakes end up turning that kinetic energy into heat.
EVs have a big advantage here. Not only is about 10% of energy lost as waste heat, but when you use the brakes on a Tesla or a Chevy Bolt, the vehicle’s motor gets used as a generator to slow the car down while actually generating electricity instead of waste heat. This is called regenerative braking.
All in all, around 90% of an EV’s energy actually gets used to move the vehicle instead of getting turned into useless and problematic heat. So, no, changing a gas car out for an EV doesn’t mean that the equivalent energy must come from a power plant. Far less overall energy is needed.
Point #2: Load Timing & Variable Grid Demand
Looking at the power grid and the total power produced in simple terms (example: “We’ll need twice as much”) isn’t informative, because the amount of power that the grid delivers to homes and businesses varies hourly. In Phoenix, the electric grid is taxed to the max in the late afternoon, when things are the hottest outside. Everybody and their dogs are running refrigerated air conditioners, and that all adds up to a lot of power.
Fast forward to midnight. The sun set hours ago, and the desert rapidly cools off up to 40 degrees. During the summer, people still need air conditioning, but the compressors (the part that uses the most electricity) only run periodically to keep houses cool. With all of the power demand cut in half, or less, some power plants are set to produce less power and other plants are turned off entirely.
The grid’s wiring has to be built for the maximum power needed, though. You can’t take the average power used in a day and put in wires that can only handle that much power (assuming you don’t want a fire). You have to take the power needs of the grid at their highest peaks on the worst days of the year and design for that, even though you won’t need those beefy wires the rest of the time.
So, in reality, the grid has tons of spare capacity most of the time. In the middle of the night when power is needed the least, grids are often only transmitting half of the power they are capable of sending, or less.
The Arizona example doesn’t apply everywhere, as some places that actually have a winter use a lot of electric power at night for heating. Other places often have a glut of excess solar power during the day that they don’t know what to do with. Sometimes they even have to pay people to take the power.
Fortunately, EVs can charge during off-peak times when there’s extra power capacity. Utilities often offer customers with an EV excellent prices to charge during those off-peak hours, so they set the EV to charge during those times instead of when everyone is competing for power.
Point #3: EV Efficiency Continues To Improve
Finally, it’s worth noting that EVs are getting more efficient. They were already far more efficient than gas-powered vehicles to begin with, but today’s EVs tend to use even less power than the EVs made ten years ago. Improved drivetrains, better aerodynamic efficiency, better battery technology, and even the use of on-board solar panels are all reducing the power needs of EVs.
Vehicles like the Aptera and Sono Sion are even going to be able to operate almost completely independent of the grid, because they’ll produce enough solar power that they just don’t need to be plugged in most days.
When we keep all of this in mind (EVs are more efficient, they can charge when the grid has the most spare capacity, and they’re getting more efficient over time), there’s really no reason to fear EVs overloading grids unless you’re looking for something to dishonestly smear the EV industry with.

EcoFlow members can save up to 65% on power stations while supporting disaster relief during the 2025 Member’s Festival
Portable power station specialist EcoFlow is kicking off its third annual Member’s Festival this month and is offering a unique new rewards program to those who become EcoFlow members. The 2025 EcoFlow Member’s Festival will offer savings of up to 65% for its participating customers, and a portion of those funds will be allocated toward rescue power solutions for communities around the globe through the company’s “Power for All” fund.
EcoFlow remains one of the industry leaders in portable power solutions and continues to trek forward in its vision to power a new tech-driven, eco-conscious future. Per its website:
Our mission from day one is to provide smart and eco-friendly energy solutions for individuals, families, and society at large. We are, were, and will continue to be a reliable and trusted energy companion for users around the world.
To achieve such goals, EcoFlow has continued to expand its portfolio of sustainable energy solutions to its community members, including portable power stations, solar generators, and mountable solar panels. While EcoFlow is doing plenty to support its growing customer base, it has expanded its reach by giving back to disaster-affected communities by helping bolster global disaster response efforts the best way it knows how– with portable power solutions.
EcoFlow and its members look to provide “Power for All”
Since 2023, EcoFlow has collaborated with organizations worldwide as part of its “Power for All” mission. This initiative aims to ensure access to reliable and timely power to disaster-affected communities across the globe, including rescue agencies, affected hospitals, and shelters, to support rescue and recovery efforts.
This fund most recently provided aid for communities affected by the recent Los Angeles wildfires, assistance to the Special Forces Charitable Trust (SFCT) in North Carolina following severe hurricanes, and support for non-profits engaged in hurricane preparedness in Florida and the Gulf Coast. Per Jodi Burns, CEO of the Special Forces Charitable Trust:
In the wake of devastating storms in Western North Carolina, reliable power was a critical need for the families we serve. Thanks to EcoFlow’s generous donation of generators, we were able to provide immediate relief, ensuring these families and their communities had access to power when they needed it most. We are so impressed with EcoFlow’s commitment to disaster response through their ‘Power for All’ program. It has made a tangible impact, and we are deeply grateful for their support and partnership in helping these families recover and rebuild.
In 2024, the US experienced 27 weather and climate events, each causing losses exceeding $1 billion, marking the second-highest annual total on record, according to National Centers for Environmental Information. The increasing frequency and severity of natural disasters underscore the critical need for reliable and timely power solutions during emergencies, much like EcoFlow and its members are helping provide through the “Power For All” initiative.
To support new and existing EcoFlow members, the company is celebrating its third annual Member’s Festival throughout April to offer a do-not-miss discount on its products and donate a portion of all sales to the “Power for All” fund to provide rescue power to those in need in the future.

Tesla is losing another top talent: its long-time head of software, David Lau, has reportedly told co-workers that he is exiting the automaker.
Tesla changed how the entire auto industry looks at software.
Before Tesla, it was an afterthought; user interfaces were rudimentary, and you had to go to a dealership to get a software update on your systems.
When Tesla launched the Model S in 2012, it all changed. Your car would get better through software updates like your phone, the large center display was responsive with a UI that actually made sense and was closer to an iPad experience than a car.
Tesla also integrated its software into its retail experience, service, and manufacturing.
David Lau deserves a lot of the credit for that.
He joined Tesla in 2012 as a senior manager of firmware engineering and quickly rose through the ranks. By 2014, he was promoted to director of firmware engineering and system integration, and in 2017, he became Vice President of software.
Lau listed the responsibilities of his team on his LinkedIn:
- Vehicle Software:
- Firmware for the powertrain, traction/stability control, HV electronics, battery management, and body control systems
- UI software and underlying Embedded Linux platforms
- Navigation and routing
- iOS and Android Mobile apps
- Distributed Systems:
- Server-side software and infrastructure that provides telemetry, diagnostics, over-the-air updates, and configuration/lifecycle management
- Data engineering and analytics platforms that power technical and business insights for an increasingly diverse set of customers across the company
- Diagnostic tools and fleet management, Manufacturing and Automation:
- Automation controls (PLC, robot)
- Server-side manufacturing execution systems that power all of Tesla’s production operations
- Product Security and Red Team for software, services, and systems across Tesla
Bloomberg reported today that Lau told his team he is leaving Tesla. The report didn’t include reasons for his stepping down.
Electrek’s Take
Twelve years at any company is a great run. At Tesla, it’s heroic. Congrats, David, on a great run. You undoubtedly had a significant impact on Tesla and software advancements in the broader auto industry.
He is another significant loss for Tesla, which has been losing a lot of top talent following a big wave of layoffs around this time last year.
I wonder who will take over. Michael Rizkalla, senior director of software engineering and vehicle firmware, is one of the most senior software engineers after Lau. He has been at Tesla for 7 years, and Tesla likes to promote within rather than hire outsiders.
There are also a lot of senior software execs working on AI at Tesla. Musk has been favoring them lately and he could fold Lau’s responsibilities under them.

Kia’s electric SUVs are taking over. The EV3 is the best-selling retail EV in the UK this year, giving Kia its strongest sales start since it arrived 34 years ago. And it’s not just in the UK. Kia just had its best first quarter globally since it started selling cars in 1962.
Kia EV3 is the best-selling EV in the UK through March
In March, Kia sold a record nearly 20,000 vehicles in the UK, making it the fourth best-selling brand. It was also the second top-seller of electrified vehicles (EVs, PHEVs, and HEVs), accounting for over 55% of sales.
The EV3 remained the best-selling retail EV in the UK last month. Including the EV6, three-row EV9, and Niro EV, electric vehicles represented 21% of Kia’s UK sales in March.
Kia said the EV3 “started with a bang” in January, darting out as the UK’s most popular EV in retail sales. Through March, Kia’s electric SUV has held on to the crown. With the EV3 rolling out, Kia sold over 7,000 electric cars through March, nearly 50% more than in Q1 2024.
The EV3 was the best-selling retail EV in the UK in the first quarter and the fourth best-selling EV overall, including commercial vehicles.
Starting at £33,005 ($42,500), Kia said it’s the “brand’s most affordable EV yet.” It’s available with two battery packs, 58.3 kWh or 81.48 kWh, good for 430 km (270 miles) and 599 km (375 miles) of WLTP range, respectively.
With new EVs on the way, this could be just the start. Kia is launching several new EVs in the UK this year, including the EV4 sedan (and hatchback) and EV5 SUV. It also confirmed that the first PV5 electric vans will be delivered to customers by the end of the year.
Electrek’s Take
Globally, Kia sold a record 772,351 vehicles in the first quarter, its best since it started selling cars in 1962. With the new EV4, the brand’s first electric sedan and hatchback, launching this year, Kia looks to build on its momentum in 2025.
Kia has also made it very clear that it wants to be a global leader in the electric van market with its new Platform Beyond Vehicle (PBV) business, starting with the PV5 later this year.
Earlier today, we learned Kia’s midsize electric SUV, the EV5, is the fourth best-selling EV in Australia through March, outselling every BYD vehicle (at least for now). The EV5 is rolling out to new markets this year, including Canada, the UK, South Korea, and Mexico. However, it will not arrive in the US.
For those in the US, there are still a few Kia EVs to look forward to. Kia is launching the EV4 globally, including in the US, later this year. Although no date has been set, Kia confirmed the EV3 is also coming. It’s expected to arrive in mid-2026.
