Hyperloop, hydrogen-powered trains, and air-taxis. As the 21st century progresses, the way people get from A to B is on the cusp of a significant shift driven by design and innovation.

While the above technologies may be a few years off from widespread adoption, that’s not to say change isn’t already afoot.

Around the world, national and municipal governments are attempting to slash emissions and boost urban air quality, with many putting their faith in a growing sector: battery electric vehicles. 

There’s undoubtedly momentum behind the industry. A recent report from the International Energy Agency stated roughly 3 million new electric cars were registered last year, a record amount and a 41% rise compared to 2019.

Looking ahead, the IEA says the number of electric cars, buses, vans and heavy trucks on roads — its projection does not include two- and three-wheeled electric vehicles — is expected to hit 145 million by 2030.

If governments ramp up efforts to meet international energy and climate goals, the global fleet could increase further still, expanding to 230 million by the end of the decade.

A changing world 

As the number of electric vehicles on the planet’s roads increases, society will need to adapt.

Extensive charging networks, for example, will need to be rolled out to meet increased demand and dispel lingering concerns around “range anxiety” — the idea that electric vehicles aren’t able to undertake long journeys without losing power and getting stranded.

Another area where we will notice change relates to noise: As well as boasting zero tailpipe emissions, electric vehicles are far quieter than their diesel and gasoline cousins.

This means less noise pollution in urban areas — clearly a good thing — but also throws up a potential challenge for other road users, especially those with sight problems. 

“For people who are blind or partially sighted, judging traffic can be really difficult,” Zoe Courtney-Bodgener, policy and campaigns officer at the U.K.-based Royal National Institute of Blind People, told CNBC in a phone interview.

Courtney-Bodgener explained that an increasing number of “quiet” modes of transport were now being used, giving the example of bicycles and larger electric and hybrid vehicles.

“If you can’t always or reliably use vision to detect those vehicles, then sound is even more important,” she went on to state.

“And when the sound is not there, or is not loud enough to be able to reliably detect those vehicles, obviously that presents danger because … you’re not reliably able to know when a vehicle is approaching you.”

The law of the land

It should be noted that, around the world, legislation and technology have already been introduced in a bid tackle this issue.

In the European Union and U.K., for example, all new electric and hybrid vehicles will have to use an acoustic vehicle alerting system, or AVAS, from July 1. This will build upon and broaden previous regulations which came into force in 2019. 

Under the rules, the AVAS is supposed to kick in and make noise when a vehicle’s speed is under 20 kilometers per hour (around 12 miles per hour) and when it’s in reverse.

According to a statement from the U.K. government in 2019, the sound “can be temporarily deactivated by the driver if judged necessary.”

The EU’s regulation says the noise made by the AVAS “shall be a continuous sound that provides information to the pedestrians and other road users of a vehicle in operation.”

“The sound should be easily indicative of vehicle behaviour,” it adds, “and should sound similar to the sound of a vehicle of the same category equipped with an internal combustion engine.”

The RNIB’s Courtney-Bodgener told CNBC that while her organization was “happy” the AVAS directive had been translated into U.K. law, it did not “do all of the things that we want it to do.”

She went on to explain how the speed at which the AVAS cuts in perhaps needed to be increased to 20 or 30 miles per hour.

“We’re not convinced that if … a vehicle is travelling at, say 13 miles per hour, it would generate, on its own, enough noise for it to be reliably detectable by sound.”

Another area of concern relates to older vehicles. “There are already lots and lots of electric and hybrid vehicles that were produced before this legislation came into force and do not have the sound technology on them,” she said.

There was currently no provision to retrofit these, she added. “That is a concern because there are already thousands of vehicles on roads around the U.K. that do not have the AVAS technology.”

From the industry’s point of view, it seems to be content with the regulations already in place. In a statement sent to CNBC via email, AVERE, The European Association for Electromobility, told CNBC it supported the “current legislative status quo.”

“The limit of 20 km/h is sufficient, since at this level other noises — notably rolling tyre resistance — take over and are sufficient for pedestrians and cyclists to hear EVs and hybrids approaching,” the Brussels-based organization added.

“In fact, mandating additional noise beyond 20 km/h would rob European citizens of one of the primary benefits of electrification: reduced noise levels at city speeds.”

Noise pollution can indeed be a serious issue. According to the European Environment Agency, over 100 million people in Europe “are exposed to harmful levels of environmental noise pollution.” The agency singles out road traffic noise as being “a particular public health problem across many urban areas.”

On the subject of older cars needing to be updated, AVERE said: “Only a very small share of EVs on European roads would be subject to retrofitting requirements, given the fact that many existing vehicles have already been fitted with AVAS in anticipation of the new requirements, and that the rules have been put in place in time to support the expected mass uptake of EVs in coming years.”

If “additional requirements” were found to be necessary, AVERE said it stood ready to engage with policymakers.

The future

Discussions and debate surrounding this topic look set to continue for a good while yet and it’s clear that a balance will need to be struck going forward.

Regardless of whether one thinks the current legislation goes far enough or not, the fact remains these types of systems are set to become an increasingly important feature of urban transport in the years ahead.

Robert Fisher is head of EV technologies at research and consultancy firm SBD Automotive.

He told CNBC via email that testing conducted by the company had “found AVAS to be quite effective” but went on to add that if a pedestrian wasn’t familiar with the noise, “they may not automatically associate it with the presence of an approaching vehicle.”

“Currently, AVAS is mostly hindered by inconsistent legislation and a lack of innovation,” he said, before going on to strike a positive tone regarding the future.

“As we move away from the internal combustion engine, this technology has the potential to become a key part of a car’s character, a point of brand differentiation, and has the ability to save lives.”

Celebrate Labor Day with these awesome (electric) work truck deals

It’s Labor Day weekend, which means big deals on car lots across America – especially if you’re shopping for a new electric vehicle to help with your labor. We’ve rounded up the best offers on electric pickups, vans, and even a great option for ride share drivers!

Sure, there’s a bit of irony in pitching “work vehicles” on a holiday meant for not working – but for many small business owners, work is part of who they are. And with the $7,500 federal EV tax credit set to expire, plus a wave of great Labor Day deals on work-ready EVs, now might be the best time yet to plug into a new electric ride.

Here are some of the standout electric vehicles offers we found this Labor Day weekend (2025), organized by vehicle type.

Electric pickup | F-150 Lightning

But wait, there’s more! Ford Authority is reporting that a complimentary home charger and standard installation might also be included as part of the Ford Power Promise promotion happening at participating dealers in select markets with the purchase of a new F-150 Lightning pickup through the end of September.

Lease customers aren’t being left out, either. You can lease a 2025 Ford F-150 Lightning XLT 4P 311A pickup at $399 per month for 36 months, with “just” $399 due at signing (basically your first month’s payment).

Electric van | Chevy Brightdrop

The best electric vehicle deal in the business keeps on truckin’ into Labor Day weekend, with new 2025 Brightdrop models currently eligible for up to $21,500 in manufacturer rebates before any Federal, state, local utility, or even Costco membership incentives kick in.

For your money, you get a capable, Ultium-based electric cargo van with more room than your college dorm and a nationwide dealer network to keep it up and running when you need it most.

Electric van (hon. mention) | Mercedes eSprinter

Despite being based on the company’s existing diesel platform, Mercedes’ eSprinter has proven itself a capable urban hauler in the hands of Amazon, DHL, and countless European tradespeople. Despite that, there are still a handful of leftover 2024 models hanging around dealer lots – enough that Mercedes is offering up to $30,000 (!) Customer Cash on any new ’24MY eSprinter purchased from dealer stock.

That discount is enough to bring the price of this 2024 eSprinter in Chicago from $87,823 all the way down to $57,823 this Labor Day weekend – and that’s before you factor in state and local utility incentives that can bring the price down even further.

As you can imagine, there’s some fine print on that Customer Cash deal. It can’t be combined with Special APR programs through Mercedes-Benz Financial Services (MBFS), but it can be combined with the Mercedes-Benz Commercial Vehicles Medium Fleet Program.

Ride share ride | VW ID.4

Ride share drivers looking for comfortable seats, room for five adults and their luggage, proven battery life, and lickety-quick charging speeds can stop looking. Volkswagen is offering a sweet ID.4 lease at nearly half the cost of an entry-level Jetta with payments starting at just $129/mo. – that’s despite the ID.4 carrying a significantly higher MSRP.

And, while we’re at it, it’s probably worth noting that serious road warriors will probably save more than $129/mo. in fuel alone.

If you prefer to own your vehicles after making payments on them for a few years, you can also get 0% interest financing on select ID.4s for up to 72 months. It’s important to note here that Volkswagen’s deals can vary wildly by region. That $129/mo. offer is available in California and a few other West Coast states, for example, but the electric crossover’s listed at $329 for 24 months with $4,499 due at signing in others.

Disclaimer: the vehicle models and financing deals above were sourced from CarsDirectCarEdge, and (where mentioned) the OEM websites – and were current as of 29AUG2025. These deals may not be available in every market, with every discount, or for every buyer (the standard “with approved credit” fine print should be considered implied). Check with your local dealer(s) for more information.

Denver Public Library deploys novel solar and battery storage system

Denver Public Library deploys novel solar and battery storage system

Sustainable construction experts McKinstry have teamed up with leading BESS developers Viridi and the Denver Public Library to deploy a first-of-its-kind solar and battery storage system that sets a new standard for fire safety.

The Denver Public Library sought a battery energy storage system (BESS) that could deliver cost savings without compromising safety for staff, visitors, or the architecturally significant, Michael Graves–designed structure itself. That required a battery backup solution that not only met the city’s fire safety standards, but also addressed public fears about the risk of lithium-ion battery fires.

That unique set of project priorities led the library to Viridi, makers of the RPSLinkEX battery solution that’s equipped with a unique, “passive Fail-Safe thermal management and anti-propagation technology” designed to prevent the sort of thermal runaway that leads to li-ion battery fires.

“Public facilities like the Denver Public Library are at the forefront of demonstrating that energy resilience and safety can go hand in hand,” said Jon M. Williams, CEO at Viridi. “This installation highlights how fail-safe battery storage can empower communities to maximize renewable energy, reduce costs, and maintain reliability – all without compromise.”

Keeping it safe

Viridi doesn’t talk too much about how its passive Fail-Safe thermal management system works, but if you’re picturing heat-dissipating layers, fire-resistant insulation, and strategically-placed phase change materials (or PCMs) limiting the transfer of heat from one cell to another if it begins to overheat, you’ve probably cracked it.

These passive safety features enable safer deployment scenarios in occupied buildings or near critical infrastructure by reducing dependence on active fire suppression systems like sprinklers or fire extinguishers, and convinced the City of Denver to move forward with the project, which is the city’s first-ever solar + battery storage system.

“The entire McKinstry team is very excited about developing and constructing the first Solar + BESS project for the City and County of Denver,” said Jon Ensley, Sr. Construction Project Engineer at McKinstry. “We are appreciative of all our partners and stakeholders who helped to achieve this goal. We value Viridi’s expertise in deploying this technology and the whole team has been great to work with.”

McKinstry says this latest solar project sets, “a new benchmark for how cities can combine renewable energy and battery storage without compromising safety.” And, with solutions like the RPSLinkEX building systems that meet city planners and politicians where they are, instead of trying to educated them about the objective, proven safety of li-ion batteries, Viridi is helping communities adopt cleaner, more resilient clean energy solutions sooner rather than later.

China installs the world's most powerful wind turbine

China’s Dongfang Electric has installed a 26-megawatt offshore wind turbine, snatching the title of world’s most powerful from Siemens Gamesa’s 21.5 turbine in Denmark.

The Chinese state-owned manufacturer announced today that it has installed the world’s most powerful wind turbine prototype at a testing and certification base. This turbine, the world’s largest for capacity and size, boasts a blade wheel diameter of more than 310 meters (1,107 feet) and a hub height of 185 meters (607 feet). Dongfang shipped the turbine’s nacelle earlier this month – the world’s heaviest – along with three blades.

This offshore wind turbine is designed for areas with wind speeds of 8 meters per second and above. With average winds of 10 meters per second, just one of these giants can generate 100 GWh of power annually, which is enough to power 55,000 homes. That’s enough to cut standard coal consumption by 30,000 tons and reduce CO2 emissions by 80,000 tons. Dongfang says it’s wind resistant up to 17 (200 km/h) on the extended Beaufort scale.

In May, Dongfang said it had completed static load testing on the turbine’s blades, and the turbine is now undergoing fatigue testing, which could take up to a year before the turbine is fully certified.
