The Cost Of Renewables Continues To Plummet
According to a new report from the Institute of New Economic Thinking at the University of Oxford, previous estimates about how quickly the price of renewables will fall have consistently underestimated reality (We think they are pointing their fingers at the International Energy Agency here.)
Here’s the first few paragraphs of the report:
“Rapidly decarbonizing the global energy system is critical for addressing climate change, but concerns about costs have been a barrier to implementation. Most energy economy models have historically underestimated deployment rates for renewable energy technologies and overestimated their costs. The problems with these models have stimulated calls for better approaches and recent reports have made progress in this direction.
“Here we take a new approach based on probabilistic cost forecasting methods that made reliable predictions when they were empirically tested on more than 50 technologies. We use these methods to estimate future energy system costs and find that, compared to continuing with a fossil fuel based system, a rapid green energy transition will likely result in overall net savings of many trillions of dollars (emphasis added) — even without accounting for climate damages or co-benefits of climate policy.
“We show that if solar photovoltaics, wind, batteries and hydrogen electrolyzers continue to follow their current exponentially increasing deployment trends for another decade, we achieve a near-net-zero emissions energy system within twenty-five years. In contrast, a slower transition (which involves deployment growth trends that are lower than current rates) is more expensive and a nuclear driven transition is far more expensive.
“If non-energy sources of carbon emissions such as agriculture are brought under control, our analysis indicates that a rapid green energy transition would likely generate considerable economic savings while also meeting the 1.5 degrees Paris Agreement target.
“Future energy system costs will be determined by a combination of technologies that produce, store and distribute energy. Their costs and deployment will change with time due to innovation, economic competition, public policy, concerns about climate change and other factors.”
“It’s not just good news for renewables. It’s good news for the planet,” co-author Matthew Ives, a senior researcher at the Oxford Martin Post-Carbon Transition Program, tells ArsTechnica. “The energy transition is also going to save us money. We should be doing it anyway.”
“Our approach is based on two key design principles: 1) include only the minimal set of variables necessary to represent most of the global energy system, and the most important cost and production dynamics, and 2) ensure all assumptions and dynamics are technically realistic and closely tied to empirical evidence. This means that we focus on energy technologies that have been in commercial use for sufficient time to develop a reliable historical record.
“We choose a level of model granularity well suited to the probabilistic forecasting methods used, i.e. one that allows accurate model calibration, and ensures overall cost reduction trends associated with cumulative production are captured for each technology. Our model design can be run on a laptop, is easy to understand and interpret, and allows us to calibrate all components against historical data so that the model is firmly empirically grounded. The historical data does not exist to do this on a more granular level.”
Omitted Technologies
“Consistent with our two design principles, we have deliberately omitted several minor energy technologies. Co-generation of heat, traditional biomass, marine energy, solar thermal energy, and geothermal energy were omitted either due to insufficient historical data or because they have not exhibited significant historical cost improvements, or both.
“Liquid biofuels were also excluded because any significant expansion would have high environmental costs. Finally, carbon capture and storage in conjunction with fossil fuels was omitted because i) it is currently a very small, low growth sector, ii) it has exhibited no promising cost improvements so far in its 50 year history, and iii) the cost of fossil fuels provides a hard lower bound on the cost of providing energy via fossil fuels with CCS. This means that within a few decades, electricity produced with CCS will likely not be competitive even if CCS is free.” (emphasis added)
Massive Storage Capacity
“Since renewables are intermittent, storage is essential. In the Fast Transition scenario we have allocated so much storage capacity using batteries and P2X fuels that the entire global energy system could be run for a month without any sun or wind. This is a sensible choice because both batteries and electrolyzers have highly favorable trends for cost and production.
“From 1995 to 2018 the production of lithium ion batteries increased at 30% per year, while costs dropped at 12% per year, giving an experience curve comparable to that of solar PV. Currently, about 60% of the cost of electrolytic hydrogen is electricity, and hydrogen is around 80% of the cost of ammonia, so these automatically take advantage of the high progress rates for solar PV and wind.”
Final Energy
“To understand these scenarios it is important to distinguish final energy — which is the energy delivered for use in sectors of the economy — from useful energy, which is the portion of final energy used to perform energy services, such as heat, light and kinetic energy.
“Fossil fuels tend to have large conversion losses in comparison to electricity, which means that significantly more final energy needs to be produced to obtain a given amount of useful energy. Switching to energy carriers with higher conversion efficiencies (e.g. moving to electric vehicles) significantly reduces final energy consumption.
“Our Fast Transition scenario assumes that eventually almost all energy services originate with electricity generated by solar PV and wind, making and burning P2X fuels or using batteries when it is impractical to use renewables directly. The Fast Transition substantially increases the role of electricity in the energy system.”
The INET report focuses mainly on the process of technological advancement, which is part of what has made renewables cheaper. Renewables have routinely performed beyond the expectations of previous papers. “They’ve been getting these forecasts wrong for quite some time,” Ives said. “You can see we’ve consistently broken through those forecasts again and again.”
Rather than a plateau on renewable energy costs, Ives said the greater likelihood is that the prices will decrease slower once things like solar and wind end up dominating the market. At that point, technological advances may very well still happen, but they might not be rolled out as frequently as they are now. “It’s the deployment that slows it down,” Ives says.
Michael Taylor, senior analyst at IRENA, agrees. He tells ArsTechnica his organization found that the cost reduction drivers — improved technology, supply chains, scalability, and manufacturing processes — for solar and wind are likely to continue at least for the next 10 to 15 years. With regard to previous forecasts, he says, “I would expect they’re overly pessimistic.”
Unforeseen issues such as the global pandemic and supply chain woes could slow the decline in the cost of renewables, as well as other barriers such as oil and gas subsidies, public opinion, permitting, and political considerations. “Just on purely economic grounds, there are increasing benefits to consumers to be had by accelerating the roll out of renewable power generation,” Taylor says. “We encourage policymakers to look very seriously at trying to remove the barriers that currently exist.”
The Takeaway
The report from the Institute of New Economic Thinking is a breath of fresh air. In particular, it explodes all the tripe being trotted out by fossil fuel companies to justify the continued use of their products. Carbon Capture? Pure baloney, a chimera they can hide behind while the continue their relentless greenwashing campaigns.
INET envisions consumers saving trillions of dollars as renewable energy takes over from thermal generation. The bottom line is we must stop burning fossil fuels as soon as possible if we want to keep the Earth habitable for humans. This report comes just in time for the COP 26 climate conference in Glasgow. In a rational world, global leaders would seize upon it as justification for moving forward aggressively with favorable renewable energy policies.
That’s unlikely. Those political leaders are beholden to fossil fuel companies, so expect a lot of rending of garments and gnashing of teeth as they try to spin their way out of the obvious. The only thing we as renewable energy advocates can hope for is that the price of renewables will get so low that anyone with the acumen of kumquat will have to recognize the truth. Ultimately, those free market imperatives reactionaries are so fond of will drive a stake through the heart of their beloved fossil fuel industry. We can’t wait!

The Honda Ruckus has earned cult status thanks to its minimalist styling, exposed frame, and seemingly endless customizability. The scooter, also known in international markets as the Honda Zoomer, has spent years being seen as a blank canvas for scooter tuners, urban commuters, and anyone who just wanted something simple, small, and kind of weird to zip around town. A few years ago, Honda finally answered the call for an updated version by announcing and producing the “Zoomer e:”, which was an electric version of the Honda Ruckus. So where is it?
When Honda launched the all-electric version of the Ruckus, the Zoomer e:, back in 2023, many fans hoped it was only a matter of time before we saw it quietly glide onto U.S. streets.
But two years later, there’s still no sign of a stateside release, and no indication that Honda plans to change that anytime soon.
The Zoomer e: was first introduced in China in early 2023 alongside two other retro-inspired electrics: the Cub e: and Dax e:.
The Zoomer e: keeps the stripped-down, industrial look of the classic gas-powered Ruckus, but swaps the 49cc engine for a 400W rear hub motor and a 48V 24Ah battery (around 1.15 kWh).
It was originally given a top speed of a mere 25 km/h (15.5 mph) to keep it street legal as an electric bicycle in its first market of China, where it also came with functional but stubby pedals so riders could pretend it was actually pedalable.
The first version of the electric scooter claimed a range of up to 80–90 km (50–56 miles) from its removable lithium-ion battery, depending on conditions.
We’ve since seen the performance bumped up to 40 km/h (25 mph) top speeds when the scooter was introduced into the Philippines market, where the local L1B classification allowed for higher speeds. It’s fairly obvious that the performance can be software-tweaked by Honda depending on the market, though likely to a limit. To achieve speeds much higher than 25 mph, a motor and controller swap may be required, though neither would be complicated.
In other words, the electric Ruckus’ debut revealed an ultra-lightweight, street-legal runabout designed for countries with expansive low-speed e-bike laws. But in the U.S., these types of quasi-e-bikes that are actually scooters are few and far between. The same performance can be had from a $1,000 electric bicycle, and in fact, Class 3 e-bikes in the US can go nearly twice as fast as the original electric Ruckus.
So Honda obviously hasn’t been in a rush to bring its low-spec version of the bike to the US market, where it would be a slower and heavier competitor to the wide range of cheap imported electric bicycles. However, its iconic design and cultural legacy have kept enthusiasm up for riders who have managed to privately import their own models. One Redditor appears to have imported two Honda Zoomer e: models in parts to assemble in the US, while someone else posted a YouTube video of his completely assembled Honda Dax e: model that was launched along the Zoomer e:.
Despite clear consumer interest and a growing market for low-speed electric vehicles, as well as Honda’s own proven interest in growing its electric scooter market, the company hasn’t made any moves to release the Zoomer e: in the US. That’s not surprising since America still lacks a robust electric scooter culture (or even a gasoline scooter culture, for that matter), and anything motorcycle-shaped that doesn’t hit 30+ mph tends to get passed over by mainstream buyers.
But perhaps that could change one day. Technically, bringing the Zoomer e: to the US wouldn’t be a monumental task for Honda. The U.S. is a self-certify country, meaning Honda could design a version that meets federal vehicle safety standards, beef up the motor and controller for higher speeds, and sell it as either a Class 2/3 e-bike, or perhaps more appropriately, as a low-speed motorcycle with a top speed in the 35-45 mph range (55-70 km/h).
With the rise of micromobility, electrification, and growing frustration with car-centric cities, now might actually be the perfect time for a reborn electric Ruckus to hit US roads. But until Honda decides to take that step, American riders will have to keep dreaming – or start importing.

BMW Motorrad’s futuristic electric scooter just got its first real refresh since beginning production in 2021. The BMW CE 04, already one of the most capable and stylish electric maxi-scooters on the market, now gets a set of upgraded trim options, new aesthetic touches, and a more robust list of features that aim to make this urban commuter even more appealing to riders looking for serious electric performance on two wheels.
The BMW CE 04 has always stood out for its sci-fi styling and high-performance drivetrain. It’s built on a mid-mounted liquid-cooled motor that puts out 31 kW (42 hp) and 62 Nm of torque. That’s enough to rocket the scooter from 0 to 50 km/h (31 mph) in just 2.6 seconds – quite fast for anything with a step-through frame.
The top speed is electronically limited to 120 km/h (75 mph), making it perfectly capable for city riding and fast enough to hold its own on highway stretches. Range is rated at 130 km (81 miles) on the WMTC cycle, thanks to the 8.9 kWh battery pack tucked low in the frame.
But while the core performance hasn’t changed, BMW’s 2025 update focuses on refining the package and giving riders more options to tailor the scooter to their taste. The new CE 04 is available in three trims: Basic, Avantgarde, and Exclusive.
The Basic trim keeps things clean and classic with a Lightwhite paint scheme and a clear windshield. It’s subtle, sleek, and very much in line with the CE 04’s clean-lined aesthetic. The Avantgarde model adds a splash of color with a Gravity Blue main body and bright São Paulo Yellow accents, along with a dark windshield and a laser-engraved rim. The top-shelf Exclusive trim is where things get fancy, with a premium Spacesilver metallic paint job, upgraded wind protection, heated grips, a luxury embroidered seat, and its own unique engraved rim treatment.
There are also a few new tech upgrades baked into the options list. Riders can now spec a 6.9 kW quick charger that reduces the 0–80% charge time to just 45 minutes (down from nearly 4 hours with the standard 2.3 kW onboard charger). Tire pressure monitoring, a center stand, and BMW’s “Headlight Pro” adaptive lighting system are also available as add-ons, along with an emergency eCall system and Dynamic Traction Control.
BMW has kept the core riding components in place: a steel-tube chassis, 15-inch wheels, Bosch ABS (with optional ABS Pro), and the impressive 10.25” TFT display with integrated navigation and smartphone connectivity. The under-seat storage still swallows a full-face helmet, and the long, low frame design means the scooter looks like something out of Blade Runner but rides like a luxury commuter.
With these updates, BMW seems to be further cementing the CE 04’s role at the high end of the electric scooter market. It’s not cheap, starting around €12,000 in Europe and around US $12,500 in the US, with prices going up from there depending on configuration. However, the maxi-scooter delivers real motorcycle-grade performance in a package that’s easier to live with for daily riders.
Electrek’s Take
I believe that the CE 04’s biggest strength has always been that it’s not trying to be a toy or a gimmick. It’s a real vehicle. Sure, it’s futuristic and funky looking, but it delivers on its promises. And in a market that’s still surprisingly sparse when it comes to premium electric scooters, BMW has had the lane mostly to itself. That may not last forever, though. LiveWire, Harley-Davidson’s electric spin-off brand, has teased plans for a maxi-scooter-style urban electric vehicle in the coming years, but as of now, it remains something of an undefined future plan.
Meanwhile, BMW is delivering not just a concept bike but a mature, well-equipped, and ready-to-ride electric scooter that keeps improving. For riders who want something faster and more capable than a Class 3 e-bike but aren’t ready to jump to a full-size electric motorcycle, the CE 04 hits a sweet spot. It delivers the performance and capability of a commuter e-motorcycle, yet with the approachability of a scooter. And with these new trims and upgrades, it’s doing it with even more style.

If you’ve ever wondered what happens when you combine a fruit cart, a cargo bike, and a Piaggio Ape all in one vehicle, now you’ve got your answer. I submit, for your approval, this week’s feature for the Awesomely Weird Alibaba Electric Vehicle of the Week column – and it’s a beautiful doozie.
Feast your eyes on this salad slinging, coleslaw cruising, tuber taxiing produce chariot!
I think this electric vegetable trike might finally scratch the itch long felt by many of my readers. It seems every time I cover an electric trike, even the really cool ones, I always get commenters poo-poo-ing it for having two wheels in the rear instead of two wheels in the front. Well, here you go, folks!
Designed with two front wheels for maximum stability, this trike keeps your cucumbers in check through every corner. Because trust me, you don’t want to hit a pothole and suddenly be juggling peaches like you’re in Cirque du Soleil: Farmers Market Edition.
To avoid the extra cost of designing a linked steering system for a pair of front wheels, the engineers who brought this salad shuttle to life simply side-stepped that complexity altogether by steering the entire fixed front end. I’ve got articulating electric tractors that steer like this, and so if it works for a several-ton work machine, it should work for a couple hundred pounds of cargo bike.
Featuring a giant cargo bed up front with four cascading fruit baskets set up for roadside sales, this cargo bike is something of a blank slate. Sure, you could monetize grandma’s vegetable garden, or you could fill it with your own ideas and concoctions. Our exceedingly talented graphics wizard sees it as the perfect coffee and pastry e-bike for my new startup, The Handlebarista, and I’m not one to argue. Basically, the sky is the limit with a blank slate bike like this!
Sure, the quality doesn’t quite match something like a fancy Tern cargo bike. The rim brakes aren’t exactly confidence-inspiring, but at least there are three of them. And if they should all give out, or just not quite slow you down enough to avoid that quickly approaching brick wall, then at least you’ve got a couple hundred pounds of tomatoes as a tasty crumple zone.
The electrical system does seem a bit underpowered. With a 36V battery and a 250W motor, I don’t know if one-third of a horsepower is enough to haul a full load to the local farmer’s market. But I guess if the weight is a bit much for the little motor, you could always do some snacking along the way. On the other hand, all the pictures seem to show a non-electric version. So if this cart is presumably mobile on pedal power alone, then that extra motor assist, however small, is going to feel like a very welcome guest.
The $950 price is presumably for the electric version, since that’s what’s in the title of the listing, though I wouldn’t get too excited just yet. I’ve bought a LOT of stuff on Alibaba, including many electric vehicles, and the too-good-to-be-true price is always exactly that. In my experience, you can multiply the Alibaba price by 3-4x to get the actual landed price for things like these. Even so, $3,000-$4,000 wouldn’t be a terrible price, considering a lot of electric trikes stateside already cost that much and don’t even come with a quad-set of vegetable baskets on board!
I should also put my normal caveat in here about not actually buying one of these. Please, please don’t try to buy one of these awesome cargo e-trikes. This is a silly, tongue-in-cheek weekend column where I scour the ever-entertaining underbelly of China’s massive e-commerce site Alibaba in search of fun, quirky, and just plain awesomely weird electric vehicles. While I’ve successfully bought several fun things on the platform, I’ve also gotten scammed more than once, so this is not for the timid or the tight-budgeted among us.
That isn’t to say that some of my more stubborn readers haven’t followed in my footsteps before, ignoring my advice and setting out on their own wild journey. But please don’t be the one who risks it all and gets nothing in return. Don’t say I didn’t warn you; this is the warning.
