Fusion power is still decades and billions of dollars away, even after this week’s major scientific breakthrough
The nuclear fusion breakthrough heralded on Tuesday was a historic event, culminating decades of research.
At the same time, fusion power will not be contributing electricity to any power grid for at least a decade, according to most industry watchers. To get there, there will have to be many more technical breakthroughs beyond what was celebrated on Tuesday — and the money to fund them.
Just after 1 a.m. on Monday, Dec. 5, researchers at the Lawrence Livermore National Laboratory in California executed a successful experiment to produce more energy from a nuclear fusion reaction than went into the lasers used to power the reaction.
“We got out 3.15 megajoules, we put in 2.05 megajoules in the laser,” said Mark Herrmann, a program director at Lawrence Livermore, on Tuesday. “That’s never been done before in any fusion laboratory anywhere in the world. So it’s super exciting.”
In a technical panel discussion after the main press announcement on Tuesday, scientists on the team recounted their reactions on learning the news.
Tammy Ma, a laser-plasma physicist at the lab, was waiting in an airport when her boss called her. “I burst into tears. I was jumping up and down in the waiting area, the crazy person.”
It took about 300 megajoules of energy from the electricity grid to fire the laser that was used in the experiment, said Herrmann on Tuesday. That’s equivalent to what is included in about two-and-a-half gallons of gasoline.
All of that energy went into the laser fusion reaction that showed net gain of about 1.1 megajoules — enough energy to boil a teakettle maybe two or three times.
“This is a science achievement, not a practical one,” Omar A. Hurricane, a chief scientist at Lawrence Livermore, told CNBC.
But the amount of energy isn’t the point. “The laser wasn’t designed to be efficient. The laser was designed to give us as much juice as possible to make this incredible conditions possible,” Herrmann said. “So there are many, many steps that would have to be made in order to get to an inertial fusion as an energy source.”
That’s partly because National Ignition Facility, where the demonstration took place, is 20 years old, and was constructed using technological components made in the 1980s and 1990s. Laser technology has progressed significantly since then.
The reason for the celebration was simply that energy was created at all.
“It’s exciting because it proves that fusion can work, and it opens the floodgates to further interest, investment, and innovation toward turning fusion into a power source,” said Arthur Turrell, a plasma physicist and the author of The Star Builders.

Researchers have achieved a breakthrough regarding nuclear fusion, a technology seen as a possible revolutionary alternative power source.

The industry will need a whole lot more firsts
Progress is happening fast, but the scope of the problem is immense.
A little more than a year ago, in August 2021, the same laboratory had another breakthrough that Hurricane billed as “a Wright Brothers moment.” That experiment achieved fusion ignition in a controlled environment for the first time, but the total energy that was put into the reaction was less than what came out.
“A plasma is said to ignite when the energy gain due to fusion reactions exceeds all energy losses, resulting in a rapid escalation of temperature, pressure, and fusion energy yield. Previously this had only been achieved in the detonation of nuclear weapons,” explained Pravesh Patel, the scientific director of the fusion startup Focused Energy and a former scientist at Lawrence Livermore.
In that 2021 experiment, the energy gain was 0.73. The Dec. 5 experiment was the first time an energy gain over 1.0 was achieved — specifically, an energy gain of 1.5.
“Getting anything above 1x is everything psychologically because it shows fusion can be a (net) source of energy!” Turrell told CNBC. “To put it another way, it is this moment when >1x is achieved that will make it into the history books.”

Patel expects to see energy gain of 4 or 5 coming out of the team at Lawrence Livermore eventually. But to make commercial fusion with lasers will require an energy gain of approximately 100x, Patel said.
To get to that level will require new facilities and new technology developments of component parts, such as efficient diode-pumped lasers.
“That will need progress in so-called ‘advanced concepts’ such as fast ignition or shock ignition, that are designed for high gain. Those concepts require new facilities to be built, so a breakthrough there will take until later this decade,” Patel said.
Moritz von der Linden, CEO of startup Marvel Fusion, also emphasized the importance of new lasers.
“Newest generation laser systems at other or new facilities must show that they can easily fire 10 laser pulses per second with high energies. Also, the targets must have an efficient energy absorption rate and be mass producible,” Linden told CNBC in a statement. “Only with optimized targets and latest-generation laser systems is it possible to show a net energy gain — the next truly revolutionary milestone. That will be one of the toughest engineering challenges imaginable to mankind.”

Funding will have to increase dramatically
While it will be more than a decade until fusion is commercialized, investors are already pouring money into the sector: The private fusion industry has seen almost $5 billion in investment, according to the industry trade group, the Fusion Industry Association, and more than half of that has been since since the second quarter of 2021.
Most of that investment gone toward a different approach called magnetic fusion, which uses a donut-shaped device called a tokamak. Only about $180 million has gone into inertial fusion, the approach that typically uses lasers, according to Fusion Industry Association CEO Andrew Holland.
Regardless of the approach, Tuesday’s announcement is significant for the industry as a whole, according to Dennis Whyte, who works at MIT and cofounded Commonwealth Fusion Systems (CFS), a leading startup working with tokamak-based fusion that’s raised more than $2 billion.
“While the technology readiness of tokamaks is higher for energy systems, the breakthrough announced yesterday was a scientific one confirming that net energy can be produced by the fusion fuels,” Whyte told CNBC. “So this is an important result for all fusion endeavors.”
In September, the Department of Energy announced $50 million will go toward private fusion companies in public-private partnerships.
That funding is a critical step for fusion to be commercial by the late 2030s, where most fusion industry watchers are aiming, Patel told CNBC, but it is not enough. There needs to be between 10 and 100 times as much investment to “meaningfully accelerate the time it will take to commercialize fusion and reduce our dependency on fossil fuels,” Patel told CNBC.
Perhaps the greatest criticism of fusion is that it will take too long to come online to be helpful in responding to climate change.
But industry participants believe that bold action can succeed in time.
“In March, the White House agreed and launched a program to work together with the private sector to shoot for a ‘pilot plant’ with a bold decadal plan,” Whyte told CNBC. “Why this timeline? Well if you work backwards from 2050, the math tells you when you need the pilot plant if you want fusion to play a role in combatting climate change, based on the scale-up times that will be required. This will be hard, but worthwhile to attempt.”

Tesla’s sales have surged to unprecedented levels in Turkey, where the American automaker delivered nearly as many vehicles last month as it did across the entire European market.
It occurred because Tesla managed to take advantage of a loophole that has now been patched.
Turkey has a consumption tax rate (ÖTV) that varies depending on the type of car.
Earlier this year, they reduced the tax rate to 10% for EVs with a power output of less than 160 kW.
Tesla vehicles wouldn’t qualify for that, but the automaker has resorted to one of its old tricks, which it also used to generate more sales in Canada back in 2021.
The American automaker software-locked the base Model Y RWD to just 160 kW of power to qualify for the lower tax rate. This significantly reduced the price and resulted in a surge of orders.
Tesla delivered 8,730 Model Y vehicles in Turkey in August, which was roughly equivalent to the total it delivered in a whole previous year in the country and comparable to about Tesla’s entire sales in Europe last month, following an approximately 40% decrease in sales.
Year-to-date, Tesla’s sales have now surpassed both previous full years combined:
However, Turkey has now patched the loophole. In July, the government announced that it would raise the base tax rate to 25% by the end of the month, but buyers could still take advantage of the tax rate if they had an invoice before then.
This resulted in a surge in demand for Tesla vehicles in Turkey, as evident in the August delivery results.
The demand was pulled forward, and Tesla is likely going to see sales slow down for the rest of the year.
That said, Tesla should still see demand settle higher than in previous years, as the OTV previously was as high as 60%.
Electrek’s Take
There has always been a strong demand for Tesla and electric vehicles in Turkey.
Back before Tesla officially entered the market, local EV enthusiasts were privately importing Tesla vehicles.
In the picture above, local early Tesla adopters in Turkey were begging the automaker to establish local service and Superchargers to support the community.
I believe there’s strong demand for Tesla vehicles in Turkey, but this specific surge is due to Tesla finding a loophole in the tax incentive, and the loophole has now been patched.

The Kia vehicles we see on the road today are a drastic upgrade from its older models. After a major rebrand, including a new logo, name, and a bunch of sleek EVs, Kia is winning over buyers.
Kia revamps the brand with new EVs, designs, and more
It’s no longer Kia Motors. Now, it’s just Kia. The South Korean automaker rebranded in 2021 with a new name, logo, and stylish new vehicle designs. However, the new “Kia” is much more than just an updated logo.
Kia is transitioning from just another traditional automaker to a full-on mobility company. The South Korean automaker introduced a series of new low-cost electric vehicles that are already winning over buyers in nearly every pocket of the globe.
After selling nearly 254,000 vehicles globally last month, Kia said the “robust sales” were driven by steady demand for new EVs and hybrids.
After delivering the first models in late 2024, the Kia EV3 has quickly become a top-selling EV in several markets. In the first half of 2025, it was the most popular retail EV in the UK and ranked sixth in all of Europe.
With the new EV4, EV5, and PV5 launching in new markets, Kia expects the run to gain momentum going into the end of the year.
Kia opened orders for the PV5, its first electric van, and EV4, its first EV sedan and hatchback, earlier this year. On Monday, it announced prices for the EV5, its Sportage-sized electric SUV, will start at £39,295 ($53,000) in the UK.
The Sportage is Kia’s global, European, and UK-wide best-selling vehicle, so many see the EV5 being what could be the brand’s biggest hit yet.
It’s already helped turn around Kia’s business in China. As it arrives in new markets, the EV5 is expected to be Kia’s top-selling EV in many of them, including Canada.
Kia is already coming off back-to-back annual sales records in Canada, but with new EVs launching, including the EV5, it expects to top it next year.
Although it has four new electric vehicles on deck, Elias El-Achhab, the vice president and chief operating officer of Kia Canada, said (via The Star), “the EV5 is the one we’re most excited about.” The compact SUV segment accounts for over one-third of all cars sold in Canada, making the EV5 a cornerstone of Kia’s growth plans.
The electric SUV will be exclusively sold in Canada in the North American market, not the US. Since it’s imported from Korea, Kia would take a significant hit from Trump’s auto tariffs if it were to sell it in the US.
In Canada, Kia expects it “to be our largest volume EV next year, and eventually our number one volume vehicle,” El-Achhab said.
Although prices have yet to be revealed, El-Achhab promises the EV5 will be “priced comparably to many of its combustion-engine equivalents but will be better equipped.”
When asked about rising car costs due to the tariffs, El-Achhab explained that “the volatility isn’t good for anyone,” but Kia is flexible enough to adjust its production accordingly. Even if Kia gets a bigger piece of the sales pie, “the pie will shrink, debt levels will go up,” Kia Canada’s vice president added, “We’d prefer not having to face that situation.”
