The world is going through historic transitions, a global shift of energy, transportation, and consumption that will impact every aspect of our lives, but is that not the norm and could we learn from De Nederlandse aardgastransiti (“the Netherlands natural gas transition“) in the 1960s?

De nederlandse aardgastransitie

De Nederlandse aardgastransitie

Humanity has not always used petroleum, natural gas, and coal as its dominant energy sources. It transitioned from wood to coal, but that transition took a long time. What can we learn from these historical transitions to effectively deal with the modern energy transition? The author, Sven Ringelberg, natural gas-free project consultant and entrepreneur behind Simpel Subsidie,  wrote his book De Nederlandse aardgastransitie: Lessen voor de De Nederlandse aardgastransitie, or Dutch natural gas transition: Lessons for the Dutch natural gas transition, which looks at the shift from coal to gas for space heating in the Netherlands in the 1960s and the lessons that we could take from this transition that took under 10 years. The book is published in Dutch by Eburon.

The Netherlands transition from coal for space heating to natural gas compared to the world transition from fossil fuels for heating, power, transport, and industrial processes might seem like comparing apple and oranges, but the energy transition is happening on multiple fronts at multiple scales. This book is primarily aimed at those thinking about the Netherlands and their current “energietransitie” away from natural gas and towards renewable energy, but all countries are facing their own energy transition and this book offers interesting insights into how on a country level the energy transition can be done. And it comes in a delightful, well-written package.

The current energietransitie in the Netherlands with projects and the creation of gas-free neighbourhoods, increasing insulation, and expanding renewable energy has a parallel with the 1960s energy transition.


Natural Gas and Glittering Nuclear Future


In 1959, the Netherlands discovered a massive gas pocket near Slochteren. The company that discovered it and the Dutch government negotiated, and 10 years later, a country that had normally only heated one room in its homes with coal had converted the majority of its cooking and heating to natural gas, and had introduced more widespread central heating.

This rapid deployment of natural gas is explored in depth in the book, from the negotiations and the reasoning behind it, including one of the main drivers and assumptions of the government at the time. In the 1960s, it was expected that nuclear power would be the future and that if the gas supply was not quickly developed and exploited, it would be hard to recoup the investment, so a plan was created to quickly develop and exploit the natural gas energy source that was expected to last 30 years. Gasunie, a company that was a public-private partnership, encouraged gas use with regressive tariffs. With the tariffs, gas got less expensive the more people used.


Something in the Air


In the 1960s, the marketing for natural gas was about the benefits of using more gas the cosiness and luxury of heat, but in the 1970s, things changed. The Club of Rome publishing the Limits of Growth in 1972 and the oil crisis in 1973 changed the focus from using as much as possible to saving as much as possible. 

The book goes into detail about this change of focus and the results, including a focus on more insulation and how gas was promoted.

The Background


The domestic heating and cooking situation in the 1950s Netherlands was split between multiple types — electric, city gas, coal, and oil. Each had its advantages and disadvantages, but town gas was dominant in cooking and coal was dominant in space heating — but this space heating was limited to the living room due to cost. In the book, Sven discusses how the post-war Netherlands was dealing with the issues of destroyed housing and sub-standard housing and worked to resolve this issue, but rising social standards had created a rising desire for more comfortable central heated homes, and while propaganda for coal talked about the comfortable living room stove, the negatives of coal, oil, town gas, and electric were well known to the users. Natural gas was abundant, cheap, cleaner, and could use the existing town gas network, which created an opportunity for natural gas to become a widespread heat and energy source if properly planned.


Year of Silence


Furthermore, the government benefited from revenue that allowed it to spend on education, infrastructure, and social welfare without tax burden, but after the initial discovery in Slochteren, the discovery was hardly reported on beyond the initial reports of a discovery. Sven Ringelberg discussed the reasons behind the “silence of Slochteren” and how the deal was not nationalization but also not privatization. The details of this arrangement included Shell, Esso, and government entities.


The Transition


The deal between the companies, national government departments, and city municipalities outlined the whole planned transition, from pricing, infrastructure, marketing materials, and the roles of each player in the transition. Sven Ringelberg goes into deep detail about this planning process and each part of the transition, from laying the large backbone of natural gas pipelines to transferring the gas from Slochteren to the municipalities, to the process of switching neighbourhoods to natural gas and retrofitting old town gas stoves.

Lessons to Learn from a 20th-Century Transition for the 21st-Century Transition


According to Sven Ringelberg, this quick (10 years) and somewhat painless transition was helped by a number of factors. One key factor was leadership from the central government that shaped the goals and provided the resources from key partners and agencies to promptly design and plan the transition, which is contrasted against what’s happening now in the Netherlands in 2021, in which municipal governments are tasked with this job but where they lack the resources and might only have “one and a half men and a horse’s head” to create pilots. The fragmentation of responsibilities and resources has led to a lack of standardization (which increases costs) and less momentum towards the goal.

Sven Ringelberg discusses how focusing on financial benefits might be the wrong route to people choosing to go gas-free, that putting a price on something does not always lead to buy-in from the public, but focus on the non-financial benefits that people get from a gas-free home is key, such as comfort or reducing your impact on the environment. This aspect will impact many customer-facing transitions, like the move from fossil fuel vehicles to electric vehicles.


Final Word


Sven Ringelberg has managed to turn a subject that could have easily been a dry, dusty, academic read into a very engaging and informative read. The book has diagrams and tables of key statics, but also anecdotes — from Pinkie from coal propaganda to Kees the gas dog. The book provides a rear-view mirror to contemplate what has taken us to here and what might be needed to keep driving towards a better future.

InMotion launches new 28 MPH electric unicycle with air suspension

InMotion, a well-known brand in the world of personal electric mobility, has officially launched its latest electric unicycle, the InMotion V9. Combining advanced technology and new safety features, the V9’s design positions this electric unicycle as a key option for urban commuters and adventure seekers alike who want good performance without spending a fortune.

Believe it or not, the electric unicycle market is quite broad. There are dozens of interesting models, offering everything from slow, beginner-friendly wheels to massively powerful and scary fast off-road electric unicycles (EUCs).

The new InMotion V9 launches as something of an in-between wheel, providing enough power and speed to keep it fun and interesting, yet without going so over-the-top that it becomes unaffordable or unapproachable by newer riders.

Priced at $1,299, the InMotion V9 is powered by a 1,000W motor that can reach peak outputs of 2,000W. This setup delivers a top speed of around 28 mph (45 km/h), positioning it well for urban streets and bike lanes, two of the most common stomping grounds for EUCs.

Range anxiety isn’t just a concern for cars; it can also affect micromobility riders. For its part, InMotion gave the V9 a fairly hefty 84V and 750Wh battery. This capacity allows the V9 to achieve up to 37 miles (60 km) per charge under optimal conditions. The UL-listed battery charges fairly quickly, reaching full capacity in approximately five hours.

One key feature of the V9 not found on most beginner-friendly wheels is its Nimbus Air suspension system, which provides 60 mm of travel to enhance rider comfort and reduce fatigue on uneven surfaces.

The included suspension is even more notable considering the V9 is currently InMotion’s lightest suspension-equipped electric unicycle, weighing around 48.5 lbs (22 kg). And speaking of weight, the EUC can support riders weighing up to 265 lbs (120 kg).

The InMotion V9 doesn’t skimp on smart features, either. Its integrated GPS tracking enables owners to remotely locate and monitor their unicycle via InMotion’s mobile app, even when powered off. Remote locking functionality further enhances security, ensuring peace of mind for riders frequently leaving their wheel unattended.

Additional smart integrations include customizable RGB side accent lights and built-in Bluetooth speakers, allowing riders to personalize their ride and stay entertained while commuting – or just keep cars and other road users more aware of their presence. The V9 also includes USB-A and USB-C ports with 20W output to ensure riders can conveniently charge their mobile devices while on the go.

Safety is always paramount in electric transportation devices, especially those that come with their own unique concerns like electric unicycles. The V9 has TÜV Rheinland UL2272 certification and “advanced fire-resistant technology” to mitigate risks further.

The InMotion V9 is now available for purchase through local InMotion dealers and via the official InMotion online store.

I don’t cover electric unicycles as often as e-bikes, scooters, and other micromobility devices, but not because they are less deserving. They’re certainly more niche, but I know that the EUC community is adamant about their advantages. And listen, I get it. They’re small and convenient to park or store inside, they don’t require much maintenance at all, and they’re pretty fun after you get the hang of them. An EUC can be intimidating at first, but once it clicks in your brain after a few learning sessions, riding one is a blast!

With the electric unicycle market continuing to gain traction, InMotion still faces competition from other premium brands. However, the V9’s comprehensive package of comfort, safety, and advanced smart features, combined with its competitive price point, should place it pretty well in the crowded landscape of personal electric transportation.

Fast charging just got sleeker: Delta's 50kW Wallbox launches in US

Fremont, California-based Delta Electronics just rolled out a sleek new 50kW DC Wallbox charger that’s designed for tight spaces at ACT Expo 2025.

This charger packs a punch in a surprisingly slim, 10-inch-thick, and lightweight (just 225 pounds!) casing that can be wall-mounted or set up on a pedestal. It’s specifically designed for tight spaces like urban parking lots, busy corporate campuses, or crowded fleet operation hubs.

Delta plans to manufacture these 50kW DC Wallbox chargers in Plano, Texas, keeping it local and supporting the rapid EV infrastructure growth across North America.

A 50 kW charger is at the low end of Level 3 fast charging speed, because you don’t always need to charge your car in 25 minutes. It’s the ideal charging speed for shopping, lunch, or seeing a film. Eng Taing, Delta’s senior VP and GM of energy & telecom Infrastructure, says, “Our focus is on seamlessly integrating high efficiency charging into the diverse scenarios of everyday life, including commercial operations, not just maximizing power output.”

With a 97% efficiency rate, the Wallbox can juice up two EVs simultaneously using either CCS1 or NACS connectors. Plus, the 23-foot cable makes it easy to accommodate nearly any parking layout, eliminating headaches during installation.

Delta’s vertical integration approach means it handles everything from design to manufacturing. But it doesn’t stop at hardware; the charger also connects to Delta’s IoT platform, offering remote diagnostics, predictive maintenance, and over-the-air updates. That hopefully means fewer disruptions and smoother operations for fleet managers and EV users.

Used EV prices fell 40%, and buyers are searching like never before

Used EV prices fell 40%, and buyers are searching like never before

More car buyers are hunting for used EVs – CarMax says searches filtered by “electric vehicle” have nearly doubled since January 2022.

CarMax saw EV searches surge in March 2022 and again in June 2024. The first spike lined up with the gas price shock after Russia invaded Ukraine, and the second came right as the Biden administration rolled out its $4,000 federal tax credit for used EVs.

The online used car marketplace’s Spring 2025 Electric Vehicle Consumer Report shows just how far used EV prices have tumbled, down over 40% between January 2022 and February 2025. By comparison, prices for gas cars, hybrids, and plug-in hybrids only slipped about 12% over the same period.

For the third year running, the Tesla Model 3 and the Model Y were in the No. 1 and No. 2 slots, respectively, from September 1, 2024, to February 28, 2025. The Chevy Bolt jumped into third place from its previous spot at No. 7 in 2024 and 2023. The Ford F-150 Lightning (7) and the Rivian R1T (10) made the top 10 for the first time, while the Tesla Model S and the Audi e-tron dropped out. The Hyundai Ioniq 5 and Nissan Leaf were at Nos. 5 and 6, and the Volkswagen ID.4 (4), Nissan LEAF (6), and the Ford Mustang Mach-E (9) made the list for the third year in a row.

What people are trading in

For the first time ever, more people are ditching sedans and coupes for EVs than SUVs. CarMax says sedans and coupes made up 44% of all EV trade-ins, up from 36% in 2024 and just 29% the year before. It’s a clear sign that the EV switch is picking up speed across more than just SUV drivers.

When customers traded in sedans for EVs during this report’s measurement period, the most common EVs they purchased were the Tesla Model 3, Tesla Model Y, and Chevy Bolt EUV. 

The top traded-in model for an EV at CarMax was the Tesla Model 3, and those who traded in a Model 3 usually went for a Model Y. The rest of the top five include the Honda Civic and Accord, the Nissan LEAF, and the Toyota Prius. The Ford F-150 truck, the top trade-in alongside the Accord in the 2024 report, dropped off the list.

Since this is CarMax’s report, it’s of course based on data sourced from its 250 stores across the US. In 2025, Oregon beat California to become the state with the highest percentage of EV sales compared to each state’s total sales at CarMax. California has previously held the top ranking since 2023. 

The West Coast continued to dominate when it came to used EV sales. California and Washington were in second and third place, respectively. Nevada and Arizona were fourth and sixth, while Utah and New Mexico (new to the top 10 list this year) held spots five and seven. On the East Coast, New York (10) appeared on the list for a second time, dropping two spots from No. 8 in 2024. 

The newcomers include Minnesota, which jumped 24 spots in a year to No. 8, and New Jersey, which moved up six slots to No. 9.
