Is nuclear energy the answer to a sustainable future? Experts are divided
Nuclear power has been touted as a proven, safe way of producing clean energy, but why isn’t it more widely adopted?

As the world pushes toward its goal of net-zero emissions by 2050, nuclear power has been touted as the way to bridge the energy gap — but some, like Greenpeace, have expressed skepticism, warning that it has “no place in a safe, clean, sustainable future.”
Nuclear energy is not only clean. It is reliable and overcomes the intermittent nature of renewables like wind, hydro and solar power.
“How do you provide cheap, reliable and pollution-free energy for a world of 8 billion people? Nuclear energy is really the only scalable version of that, renewables are not reliable,” Michael Shellenberger, founder of environmental organization Environmental Progress, told CNBC.
Governments have started to pour money into the sector after years of “treading water,” according to a report by Schroders on Aug. 8.
According to the report, there are 486 nuclear reactors either planned, proposed or under construction as of July, amounting to 65.9 billion watts of electric capacity – the highest amount of electric capacity under construction the industry has seen since 2015.
Only a few years ago, the International Energy Agency had warned that nuclear power was “at risk of future decline.” The report in 2019 said then that “nuclear power has begun to fade, with plants closing and little new investment made, just when the world requires more low-carbon electricity.”
Schroders noted that nuclear power is not only scalable, but much cleaner — emitting just 10-15 grams of CO2 equivalent per kilowatt hour. That’s competitive with both wind and solar energy and substantially better than coal and natural gas.
Nuclear power is also the second largest source of low carbon energy after hydro power, more than wind and solar combined, Schroders said.
Shellenberger’s view is that renewable energy is reaching the limits of what it can achieve in many countries. For example, hydroelectric power is not viable in all countries, and those that have them are “tapped out,” which means they cannot exploit any more land or water resources for that purpose.
Nuclear power is a great alternative, with “very small amounts of waste, easy to manage, never hurt anybody, very low cost when you build the same kind of plants over and over again,” he added.
That’s the reason why nations are having a second look at nuclear power, Shellenberger said. “It’s because renewables aren’t able to take us where we need to go. And countries want to be free of fossil fuels.”
Nuclear safety
Twelve years after Fukushima, we’re just getting better at operating these plants. They’re more efficient, they’re safer, we have better training.

In an interview with CNBC’s “Street Signs Asia” last week, Adam Fleck, director of research, ratings and ESG at Morningstar, said the social concern around nuclear power is “somewhat misunderstood.”
While the tragedies in Chernobyl and Fukushima cannot be forgotten, using nuclear is one of the safest ways to produce energy, even taking into consideration the need to store the nuclear waste.
“Many of those [storage facilities] are highly protected. They’re protected against earthquakes, tornadoes, you name it. But there’s a reason why there hasn’t been a significant tragedy or concern related to storage of nuclear waste.”
Shellenberger said: “Twelve years after Fukushima, we’re just getting better at operating these plants. They’re more efficient, they’re safer, we have better training.”
There have been new designs for nuclear power plants that have also enhanced safety, “but really what’s made nuclear safe has been the kind of the boring stuff, the stuff of the trainings and the routines and the best practices,” he told CNBC.
Too expensive, too slow
So, if nuclear has been a tested, proven and safe way of generating power, why isn’t it more widely adopted?
Fleck said it boils down to one main factor: cost.
The extra time that nuclear plants take to build has major implications for climate goals, as existing fossil-fueled plants continue to emit carbon dioxide while awaiting substitution.
Greenpeace
“I think the biggest issue of nuclear has actually been cost economics. It’s very costly to build a nuclear plant up front. There’s a lot of overruns, a lot of delays. And I think, for investors looking to put money to work in this space, they need to find players that have a strong track record of being able to build out that capacity.”
But not everyone is convinced.
A report by global campaigning network Greenpeace in March 2022 was of the position that besides the commonly held concern of nuclear safety, nuclear energy is too expensive and too slow to deploy compared to other renewables.
Greenpeace noted that a nuclear power plant takes about 10 years to build, adding “the extra time that nuclear plants take to build has major implications for climate goals, as existing fossil-fueled plants continue to emit carbon dioxide while awaiting substitution.”
Furthermore, it points out that uranium extraction, transport and processing are not free of greenhouse gas emissions either.
Greenpeace acknowledged that “all in all, nuclear power stations score comparable with wind and solar energy.” However, wind and solar can be implemented much faster and on a much bigger scale, making a faster impact on carbon emissions and the clean energy transition.
Nuclear power is a “distraction” from the “answer we need” — such as renewables and energy storage solutions to mitigate the unreliability from renewables, said Dave Sweeney, a nuclear analyst and nuclear-free campaigner with the Australian Conservation Foundation.
“That’s the way that we need to go, to keep the lights on and the Geiger counters down,” he told CNBC’s “Street Signs Asia” on Friday.
ALSO, the electric bike spin-off from EV-maker Rivian, just dropped some welcome news: a more affordable version of the bike is coming. Officially called the TM-B, the new model will launch at $3,500, coming in a full $1,000 under the previously announced $4,500 TM-B Performance we saw last month.
While the Performance model leaned heavily into premium components and higher output, the new TM-B appears designed to bring the platform’s eye-catching design to a wider audience.
The TM-B includes much of the same design and basic feature set as the TM-B Performance, though the $1,000 lower price tag does come from the company filet-ing a few corners. The bike drops from the 10x assist of the Performance edition to just 5x assist (presumably meaning half the power, but it’s hard to say since e-bike companies generally don’t list power as a multiple of rider input). It also has a smaller battery, more basic coil spring shock instead of the nicer and lighter air shock, fewer ride modes, and doesn’t come with the same premium styling options.
The bike does retain ALSO’s interesting drive-by-wire solution though, which means that there isn’t a physical connection between the pedals and the bike. Instead, riders turn pedal cranks connected to a generator that converts pedaling energy into electrical energy to feed the rear wheel through a Gates carbon belt drive.
Hydraulic disc brakes along with ABS-braking come standard on both models, and the cockpit includes a compact color display with app connectivity, offering basic ride metrics and configurable assist modes.
ALSO hasn’t committed to an exact delivery date, but reservations are now open.
Electrek’s Take
A $3,500 entry point is undeniably better news for fans of ALSO’s design language who weren’t ready to shell out $4,500. However, I still seem to be one of the few in the industry who are hesitant to believe there is a path to profitability here. Americans don’t buy $4,500 e-bikes, at least not in high volume, and they don’t really buy $3,500 e-bikes, either.
It’s not that the bike isn’t worth it – ALSO’s engineers should be commended for stuffing a crazy amount of tech and innovation into this bike. But it simply won’t matter when the bike doesn’t sell very many units and ALSO has to keep making payroll on its huge workforce comprised of many expensive engineers and other tech roles. It’s very close to the same playbook that we watched sink other tech-forward e-bike companies like VanMoof, which went bankrupt after it couldn’t keep up with servicing its expensive and proprietary e-bike tech while trying to float a massive workforce.
Frankly, I’m a bit confused. Most basic e-bike media seems to be going nuts over the thing, and I’m the only one pointing out that the king appears to be walking around naked.
Also, the timing here is… odd.
Good news usually gets announced on a Tuesday morning, not sent to us at 4:56 PM on a Friday, right as everyone logs off and heads into the weekend. The classic “Friday news dump” is where companies hide things they don’t want attention on – not where they brag about slicing $1,000 off the entry price of a new model. A head scratcher all around.
Either way, a lower-priced TM-B is objectively good news. The problem is, it might just be shouting into the wind.

Founded in 1689, Husqvarna was a musket maker for the king of Sweden – but now, the company best known for quirky motorcycles and commercial riding mowers is becoming an innovator in the field of robotics, and its latest fleet of electric autonomous mowers are eager to get grazing.
Husqvarna’s autonomous lawnmowers made history earlier this year at the AIG Women’s Open, when they became the first autonomous groundskeeping solution to see duty during a UK Major golf week.
“At the AIG Women’s Open, the Husqvarna portfolio is helping us deliver this goal through improved resource management, regular lightweight mowing and reduced carbon usage,” explains Royal Porthcawl’s Course Manager, Ian Kinley, who has championed the use of robotic technology at the course. “With the AIG Women’s Open set to be the largest-ever women’s sporting event in Wales, we know there’s tremendous pressure to produce playing surfaces that are worthy of such a high-profile event.”
The robots themselves operate a bit differently than Husqvarna’s traditional line of big, bad, zero-turn riding mowers that whip through thick grass once or twice a month with heavy, whirling blades. Instead, they employ a series of tiny razor blades that gently nibble at the grass daily – just like little electric sheep grazing on the turf.
“That cutting system, developed by Husqvarna engineers, has then become the basis for the entire robot mower industry, of which we’re the market leader,” Nick Rawson, VP of Strategy and Business Development at Husqvarna told Forbes.
Events like the AIG Women’s Open are proving that the little robot Huskies can get the job done quietly, sustainably, and with significantly less operator input. As such, you’d think everyone at Husqvarna would be excited about them.
You’d be wrong. The company’s franchise dealers have been hesitant to push them forward, effectively putting the parent company in the position of going B2C, or going home.
“Dealers live and breathe the previous technology,” said Yvette Henshall-Bell, Husqvarna’s President of its Forest and Garden division for Europe, in that same Forbes piece. “They want to protect that servicing, that aftermarket revenue. Whereas if they really thought about what the customer’s problems are and the job to be done, they would be looking at a completely different solution.”
A solution, frankly, that looks a lot like a little robot mower.
The things, themselves
Husqvarna offers three types of autonomous electric mowers aimed at commercial golf courses, but the Husqvarna CEORA for large-area mowing, and Husqvarna Automower, for smaller, steeper and more complex areas, are the models relevant to this story.
The bigger CEORA can handle up to 18 acres of ground twice each week, while the Automower, with its 80V battery and pinpoint precision EPOS (Exact Positioning Operating System) software, can handle another 2.5 acres. Both are fully electric, and can guide themselves back to their pens to recharge as needed.
Prices aren’t public, but the Husqvarna CEORA and Automowers are available as part of a custom lease package through Husqvarna Finance that will include access to the company’s customizable back end and ongoing support. Check with your local dealer for more.
Electrek’s Take
As a typically pro-union, pro-labor type of guy, I am hesitant to heap praise upon a robot taking away anyone’s job. That said, it does seem to be difficult for landscapers and construction crews to keep and find good labor at rates they can afford (and, let’s face it – the current Trump Administration isn’t going to be making that any easier). As such, if companies like Husqvarna and John Deere and Einride and others can build a demonstrably better mousetrap at a compelling price point … good for them. (?)
