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.
The feces-filled freight train of dystopian horrors rolls on with the passage of the Big Beautiful Bill and the untimely demise of the $7,500 federal EV tax credit. But if you’re ready to pull the trigger on a new EV this month, you’re in luck! There are plenty of great options with zero interest financing to choose from … and one with zero interest in general.
You know how we usually do these lists – some pictures, a few punchy paragraphs, and an invitation to explore local deals.
We’re doing things a little differently this month. Instead of brief write-ups, we’re highlighting the most significant 0% deal of the month (yes, that is largely opinion-based – thanks for noticing), and an “honorable mention” that doesn’t quite fit the 0% EV deal template … but might still be worth checking out.
Enough talk! Here are the deals.
Most significant new 0% offer
Demand for Tesla Cybertrucks has been a long, long way from the “conservative” 250,000 per year projections Elon was making just a few years ago. Demand for the low-poly electric pickup is so dismal, in fact, that Tesla is offering 0% financing on a new Cybertruck for up to 60 months – if you’re willing to spring for the company’s Full Self Driving (Supervised) level 2 ADAS.
Not quite a 0% EV deal
Don’t act surprised – my Twitter handle is VolvoJo, after all, and I’m on my fifth consecutive long-roof Swede as I type this. As such, when trying out a new format for this monthly column it made perfect sense to check out the Ironmark’s offers … and I found a good one: a new, not perfect but getting there seven-passenger EX90 at 1.99% financing plus $1,000 in “Summer Safety Bonus Cash.”
Is zero interest financing good enough to overcome the fact that most people seem to have zero interest in buying a CT these days? Is the Volvo worth a look at 1.99% with an additional $1,000 cash back? Let us know your take in the comments – but before you do that, check out the full list of 0% interest EV deals for July 2025 and click the links for additional local deals.

The new Lectric XP Trike2, just unveiled today, is the hands-down winner in the best-bang-for-your-buck category of electric trikes. And as perhaps the longest-running electric bike reviewer in the industry, I can say that with confidence. I’ve seen a lot of electric bikes in my time. I’ve spent a lot of butt-in-saddle hours on e-trikes. But I’ve never before seen a value like this roll by on three wheels.
As an able-bodied, mid-30s electric bike rider (and writer), I’ll be the first to say that electric trikes aren’t just for older folks. They’re fun e-bikes in their own right. But let’s face it – the vast majority of the market for electric three-wheelers are those who just aren’t as comfortable on two wheels due to age, accessibility, or other reasons. And so if you’re a senior or otherwise on the hunt for a fun and affordable electric trike, the Lectric XP Trike2 is probably the one you’re going to end up getting, and deservingly so!
If you don’t know Lectric eBikes, they’re the Phoenix-based e-bike company that took the US by storm in the early 2020s, quickly growing into the #1 best-selling e-bike company on the continent. They started with the ultra affordable, high-value XP line of e-bikes, and then took that same recipe to other types of e-bikes, from cargo bikes to off-roaders, and now to trikes.
The new XP Trike2 is the latest generation of their best-selling e-trike, and it’s absolutely better than ever.
First of all though, let’s look at what stayed the same. The ultra-affordable price of $1,499 remains untouched, keeping this not only one of the best e-trikes on the market, but also the most affordable. It also keeps the low step-over height for easy mounts and dismounts, the folding frame to help riders transport it more easily, and the powerful motor that makes it a great hill climber.
Other than those features, basically everything else has received an upgrade.
First of all, we now get included suspension with a 50mm suspension fork up front. The frame has been redesigned with a new hydroformed aluminum downtube and a more stable footprint. The stem angle has been modified to make it more comfortable and allow a more upright, relaxed riding posture. A more powerful and longer-range version of the Trike2 is also available, upgrading the motor with 50% more power for even better hill climbing, as well as including a torque sensor for more responsive pedaling and a longer-range battery.
The included TFT color screen is a major upgrade over the older model, and there are even six new colors to choose from, which is a major improvement over the original XP Trike’s color option list of… one.
Base model versus the long-range upgrade
Both the base model (Lectric XP Trike2 500) and the higher-spec option (XP Trike2 750) are compelling options, but they’ll likely serve different types of riders.
Even the base model comes with a reasonably large 13 Ah (624 Wh) battery, which is already going to give most riders at least 30 miles of range (or a claimed 50 miles if using low power pedal assist and riding slower). Plus, the 500W motor is actually much more powerful, likely peaking at closer to 1,000W of actual power. That’s the “oomph” that riders will feel when climbing hills. And for many folks, that’s plenty. Plus, the $1,499 price of the XP Trike2 500 is quite attractive.
But riders who want to upgrade to the XP Trike2 750, the higher price of $1,799 does come with some nice upgrades. First of all, the higher power 750W motor will be that much better at climbing hills, helping riders up steeper inclines, or just maintaining higher speeds up the same slopes. Next, the larger 17.5 Ah (840 Wh) battery is going to give more range, to the tune of nearly 50 miles with mixed riding (or the claimed 70 miles if using lower power pedal assist and staying off the throttle). The other benefit of a bigger battery is that it simply doesn’t need to be charged as often. Even if you’re riding around at 10 mph for an hour each day, that’s a week of riding before you have to think about recharging the battery.
The last significant upgrade on the 750W model is a torque sensor, which is a more refined pedal assist sensor that results in a more natural feeling ride when pedaling. For riders who only use the throttle, there’s not much benefit to a torque sensor. But for anyone who actually wants to pedal along and get a bit of fitness in, the torque sensor means the acceleration and the riding just better mimic the natural feel of bicycle pedaling, making it more like real pedaling – albeit if you had the legs and muscle definition of a professional cyclist.
All of this is to say: The base model with 500W of power is likely sufficient for most riders, but that extra $300 does offer better hill climbing, more power, longer range, and a nicer pedaling experience – which may be important for some riders.
Lectric may have announced the XP Trike2 today, but they aren’t quite ready to ship. In something of a throwback to Lectric’s early days, the bikes are available on pre-order. Orders placed now get priority, with the 500W model shipping later this month (July 2025). The 750W models will take a bit longer, with current orders expected to ship by September.
It’s a bit of a delayed gratification situation, but if the XP Trike2 is anything like the original (and it looks to be even better), then these bikes are absolutely going to be worth the wait!
Electrek’s Take
Once again, Lectric has left all the other e-bike makers fighting over second place. My hat is off to the company – time and again they have surprised us with increasingly better e-bike generations at increasingly the same price. Each time they roll out a bike, they give us more and more, all without touching the price tag.
The XP Trike2 follows that strategy perfectly, though it definitely looks like they’re hoping the XP Trike2 750 will bring slightly fatter margins – perhaps making up for just how ridiculously affordable the XP Trike2 500 is. And while I think the lower power model will be sufficient for most people, that bigger battery, beefier motor, and nicer torque sensor do sound like a tempting upgrade.
I haven’t ridden the XP Trike2 yet, but I will be on it soon and I can’t wait to share the experience with you guys. In the meantime, let’s hear what you think about the new e-trike in the comment section below!

Japanese equipment giant Kubota brought 22 new or updated machines to the 2025 bauma expo earlier this year, but tucked away in the corners was a new retrofit kit that can help existing customers decarbonize more quickly, and more affordably.
No matter how badly a fleet may want to electrify, harsh economic realities and the greater up-front costs typically associated with battery electric remain high hurdles to overcome, but new retrofit options from major manufacturers are popping up to help lower those obstacles.
The latest equipment maker to put its name on the retrofit list is Kubota, who says its kit can be installed by a trained dealer in a single day.
That’s right! By this time tomorrow, your diesel-powered Kubota KX019 or U27-4 excavator (shown) could be fitted with an 18 or 20 kWh li-ion battery pack and electric drive motors and ready to get to work in a low-noise or low-vibration work environment where emissions are a strict no-no. Think indoor precision demolition or historic archeological excavation.
Then, if necessary, it can go right back to diesel power.
From diesel to electric and back again
If that sounds familiar, that’s because we’ve talked about a similarly flexible power solution from ZQUIP. The battery packs and diesel engines are much larger in that application, but the basic sales pitch remains the same: electric when it benefits your operation, diesel it doesn’t.
Kubota says its modular retrofit kits is a response to the increasing global demand for sustainable alternatives by focusing on making machinery that’s flexible and repairable enough to be “reusable,” and offer construction fleet managers a longer operational lifespan, superior ROI (return on investment), and lower TCO (total cost of ownership) than the competition.
Kubota’s solution also notably reduces maintenance costs and operational overheads. With no engine and associated components, servicing time and expenses are considerably reduced, saving customers both time and money. Additionally, with electricity costing far less than fossil fuels, it offers a highly economical advantage.
International Rental News reports that other changes to the excavators include a more modern cab controls with a digital instrument cluster, a 60 mm wider undercarriage for more stability, and an independent travel circuit allows operators to use the boom, dipper, bucket, and auxiliary functions without an impact on tracking performance.
Kubota’s new kit, first shown at last year’s Hillhead exhibition in the UK, will officially be on sale this summer – any day now, in fact – though pricing has yet to be announced.
Electrek’s Take
If you’re wondering how it is that we’re still talking about bauma 2025 a full quarter after the show wrapped up, then I haven’t done a good enough job of explaining how positively massive the show was. Check out this Quick Charge episode (above) then let us know what you think of Kubota’s modular power kits in the comments.
