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.

Nuclear the only cheap, reliable way to produce zero-carbon power in a scalable way: Advocacy group

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.

There hasn't been a 'significant tragedy' related to nuclear waste storage, says Morningstar

“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.”

Nuclear-free campaigner says the nuclear industry is a 'high cost, high risk' one

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.

Stock picks and investing trends from CNBC Pro:

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.

A cold gold rush? The race for the Arctic’s critical minerals is heating up

A cold gold rush? The race for the Arctic's critical minerals is heating up

A global scramble to exploit the Arctic’s untapped resources appears to be kicking into overdrive.

In a push to break China’s mineral dominance, countries around the world are increasingly turning to the thawing and sparsely populated northern polar region, seeking to seize its raw materials and benefit from new commercial trade routes.

U.S. President Donald Trump, for example, has repeatedly underscored the importance of Greenland, a vast Arctic territory, calling U.S. ownership of the island an “absolute necessity” for economic and national security reasons.

Canada has recently sought to ramp up Arctic investment as part of a push designed to unlock its resource potential, particularly amid strained diplomatic ties with the U.S.

Russia, which has a sprawling Arctic coastline, has long recognized the region as a strategic priority. Indeed, President Vladimir Putin on Tuesday lauded the construction of a new nuclear-powered icebreaker ship to navigate Arctic waters, saying “it’s important to consistently strengthen Russia’s position” in the region.

“The Arctic is seen as a source of a lot of different raw materials, not only oil and gas, but a lot of strategic materials and rare earths,” Marc Lanteigne, associate professor at the Arctic University of Norway in Tromso, told CNBC by telephone.

“Greenland, right now, is a repository of a lot of base metals, precious metals, gem stones, rare earths, uranium … it’s all there. The problem is that up until recently, it was seen as completely unviable to actually mine them,” Lanteigne said.

“But with climate change and the ability to navigate the Arctic Ocean much more frequently, especially during the summer months, Greenland is starting to be looked at much more carefully as a potential alternative source for a lot of these strategic materials to China.”

Why everyone wants a piece of Greenland

Greenland has been transformed by the climate crisis. A major analysis of historic satellite images, published last year by researchers at the U.K.’s University of Leeds, showed parts of the autonomous Danish territory’s ice sheet and glaciers have been replaced by wetlands, areas of shrub and barren rock.

For mining companies, the major ice loss has inadvertently made some of the island’s strategic minerals more accessible.

Tony Sage, CEO of Critical Metals, which is developing one of the world’s largest rare earth assets in southern Greenland, said there has been a notable upswing in investor interest in Greenland in recent months, particularly since Trump returned to office and raised the prospect of seizing control of the territory.

“I remember in his first term, in around 2018 and 2019, he made a big song and dance about the strategic value of rare earths in Greenland, so even back then,” Sage told CNBC by telephone.

Perception vs. reality

Alongside Critical Metals, mining and exploration company Amaroq is also working to exploit some of Greenland’s resources. Amaroq CEO Eldur Olafsson said the firm’s recent discovery of high-grade rare earths in southern Greenland “means a lot to us.”

The project, which will take several years to develop, marked the firm’s first foray into the rare earths space as it expands its interests beyond gold and other strategic minerals.

Just one week after unveiling its rare earths discovery, the company on Nov. 11 confirmed commercial levels of germanium and gallium at its west Greenland hub, a development that Olafsson said could prove to be even more strategically significant.

“The germanium, gallium piece is, in my opinion, much bigger news than people understand,” Olafsson told CNBC by video call.

Germanium and gallium are essential components to a wide range of goods, from electric vehicles to semiconductors and military applications.

China, which is the primary global producer of these metals, imposed initial export controls on germanium and gallium in 2023, before singling out the U.S. with an outright ban late last year in response to curbs imposed on its chip sector by Washington. Beijing has since suspended its ban of gallium and germanium exports to the U.S., although the metals remain subject to restrictive measures.

“That is a mineral that the U.S. and the European Union need now. The rare earths are being processed by Lynas and MP Materials. That is something that you can access, I wouldn’t say easier, but you can access it … Germanium and gallium, if you don’t have them then that is a massive problem,” Olafsson said.

“We now have a short-term solution in mining terms to mine zinc, lead, silver and germanium and gallium, while we are then developing exporting the rare earths as well.”

Olafsson said it was important for the company to generate cashflow through its portfolio of gold and other strategic metals while it seeks to deliver on its rare earths potential, noting that the rare earths market is still relatively small.

Asked whether the race for the Arctic’s resources could be compared to a gold rush, Lanteigne said: “This is where perception and reality tend to kick in.”

He added: “There has been a lot of discussion about a rush to develop mineral resources in Greenland, for example, but I can say having been there quite a few times that if you are going to set up a mine then you need to bring in literally everything.”

Even in ideal conditions, Lanteigne said logistical challenges, such as Greenland’s harsh climate and remote landscape, means it could take 15 to 20 years before companies start to turn a serious profit.

Niklas Johansson, senior vice president public affairs and external relations at LKAB, said the company is currently in discussion with European lawmakers to ensure that it will be economically viable to develop its resources.

“We’ve already got the material up to the ground. That’s all been paid for by the iron ore. Still, it’s not a given that this is a business case. It looks like it is for us at the moment, but it’s not something that you’d say, ‘oh it’s a no brainer, just run for it,'” Johansson told CNBC by telephone.

“I also tell them that if it looks like this for us, who has most of the infrastructure and everything in place, how do you think it will look for others in Europe?”

Mercedes takes out the trash as German city deploys 18 electric garbage trucks

Mercedes takes out the trash as German city deploys 18 electric garbage trucks

The German city of Karlsruhe is setting an example for sustainability in waste management by deploying a fleet of 18 Mercedes-Benz eEconic electric garbage trucks that are helping make the streets cleaner, quieter, and a lot less stinky.

Since the end of September, the city of Karlsruhe has been relying on Mercedes’ fully electric waste collection vehicles throughout, with none of the area-specific restrictions or limited rollout strategies for one or two trucks at a time that typically accompany stories like these. Instead, the city is using the Mercedes eEconics for the same stuff they’d use the diesel versions for: residual waste disposal, paper collection, and bulky waste collection.

Normal garbage duty, in other words. And, in such daily use, they do a great job. The trucks cover an average route distance of around 80 km (about 50 miles) on 112 kWh battery packs (usable capacity is ~97 kWh) which can be reliably completed in single-shift operation without intermediate charging — thanks, in part, to Mercedes’ efficient electric motors and regenerative braking that shines in the trucks’ typical stop-and-go duty cycles.

More than a single shift, in fact. The fleet managers report that after “a good 80 kilometers with around 60 stops on its daily route,” energy consumption was only around 35% of the battery capacity, meaning the charge level dropped from 100% to 65% and 64% respectively.

At the same time, CO₂ emissions are significantly reduced: depending on the area of application, each eEconic can save between 150 and 170 tons of CO₂ per year. This results in a total potential annual saving of around 1,200 tons of CO₂ emissions.

The purchase of the electric vehicles was funded by the Federal Ministry of Transport (BMV) as part of the guideline on the promotion of light and heavy commercial vehicles with alternative, climate-friendly drives and the associated refueling and charging infrastructure (KsNI). The funding guideline was coordinated by NOW GmbH, and applications were approved by the Federal Office for Logistics and Mobility.

Electrek’s Take


Look, you know me. There is absolutely ZERO chance that I’ll be able to remain objective about anything that’s putting down more than four thousand lb-ft of torque. Make that thing quieter, cleaner, and generally better for me and my community, and there’s even less of a chance of me saying anything critical about it.

Here’s hoping more cities go electric rather sooner than later.

Electreon snaps up InductEV’s wireless charging tech in new MoU

Electreon just took a big step toward expanding wireless EV charging. The Israel-based company signed a memorandum of understanding (MoU) to acquire the assets of InductEV, a Pennsylvania-based firm known for its ultra-fast, high-power static wireless charging systems used by heavy-duty electric transit and freight fleets.

If the deal closes after due diligence and regulatory approvals, the combined company would bring together Electreon’s dynamic wireless charging tech – the kind that can charge vehicles while they drive – with InductEV’s high-power stationary systems. That would create one of the most complete wireless charging portfolios on the market, covering everything from passenger EVs to vans, buses, heavy-duty trucks, and even autonomous vehicles.

Electreon and InductEV together hold around 400 granted and pending patents, and have a lot of field experience across their respective projects. Electreon says that pairing its manufacturing capabilities and global footprint with InductEV’s ultra-fast tech will help streamline and speed up fleet electrification.

Both companies already work with major vehicle OEMs, which Electreon asserts will make integrating wireless charging into future vehicle platforms easier.
