EVs won’t save us from high gas prices
With gasoline costs hovering above $4 a gallon, electrical autos are beginning to look much more engaging to automobile patrons. However a mixture of provide chain constraints, the worldwide chip scarcity, higher-than-average costs, and low stock at dealerships will conspire to maintain EVs out of attain for most individuals.
Curiosity in switching from gasoline to electrical is at an all-time excessive. Automotive purchasing web site Edmunds stories the variety of individuals looking for hybrid, plug-in hybrid, or electrical autos jumped 39 % from February to March and 18 % over the past week.
Following by on that buy goes to be powerful for most individuals, given the shortage of latest EVs in the marketplace. The EVs which can be out there are dearer than their gasoline equal, and stock is extraordinarily low. The identical goes for hybrids and small to midsize automobiles, which usually fall close to the underside when it comes to provide. So for anybody on the lookout for aid from excessive gasoline costs, the answer is both persistence — extra EVs are coming! — or much less driving.
EV gross sales have elevated exponentially year-over-year, however they nonetheless account for less than 4.5 % of latest automobiles bought within the US. The typical sale value of a brand new EV remains to be about $10,000 greater than the general business common that features gasoline and electrical automobiles. When it comes to pricing, an EV is the equal of an entry degree luxurious car.
Even in the event you can afford a brand new EV, good luck discovering one. US car stock ranges — the variety of automobiles which can be in the stores at any given time — are down about 60 % from a yr in the past and 70 % from 2020 to roughly 1.1 million autos, in keeping with Cox Automotive. EVs and hybrids solely characterize about 25,100 models, or 2.4 % of that complete provide, as of February twenty first, in keeping with the corporate.
“If leaping into a brand new EV is a prime precedence for you proper now, it’s not going to be significantly simple to make a purchase order,” stated Jessica Caldwell, govt director of insights at Edmunds.
Automakers have been sluggish to acknowledge the demand for EVs; it wasn’t till Tesla’s valuation began to skyrocket that almost all automobile corporations’ EV plans actually kicked into excessive gear. And earlier than that, the auto business deprioritized or phased out utterly extra fuel-efficient autos, like sedans and wagons, in favor of giant vans and SUVs, which have larger revenue margins and eat extra gasoline.
In recent times, automakers have discontinued smaller, extra fuel-efficient autos just like the Honda Match, Chevy Sonic, Ford Fiesta, and Toyota Yaris. Of their place, we’re getting behemoths, just like the Cadillac Escalade, or much more midsize SUVs, just like the Ford Bronco.
Unsurprisingly, homeowners of outsized autos are feeling the ache of upper gasoline costs probably the most. A driver of a full-size SUV is paying about $110 extra every month to function their car, in keeping with Cox. A full-size pickup now prices $100 extra a month to function in comparison with March 2021.
The final time gasoline costs exceeded $4 a gallon, throughout the monetary disaster of 2008, demand for big autos cratered. Extra automobile patrons turned to fuel-efficient autos, and a few stopped purchasing altogether.
The dynamic is completely different this time round. Excessive gasoline costs are colliding with car shortage, provide chain constraints, and the worldwide chip scarcity, creating an ideal storm of suckiness for automobile patrons. The automobiles they might have turned to — small, fuel-efficient, and even simply electrical — aren’t out there. What is on the market are big vans and SUVs, just like the Ram 1500 or Jeep Grand Cherokee, each of which Cox Automotive says are probably the most available new autos proper now.
“We live in a time like no different,” stated Michelle Krebs, a senior analyst for Autotrader and Cox Automotive.
To make issues worse, automobile sellers are making use of big markups to most new EVs. In accordance with Edmunds, the typical transaction value for a brand new EV is up 3 % in February over the producer’s advised retail value, largely due to markups. That’s steeper than the uptick within the common transaction value for all new autos (gasoline and EV) in February, which was 1.5 % above the typical MSRP. And keep in mind, the typical MSRP for an EV is already dearer: the typical value of a brand new EV was over $60,000 in February.
On prime of all that, uncooked materials costs are going up. Russia’s invasion of Ukraine is driving up costs of metal, nickel, and palladium — utilized in physique panels, exhaust-purifying catalytic converters, and EV batteries. In accordance with Bloomberg, uncooked materials prices have been about 10.5 % of the typical value paid for brand spanking new autos in January, up from 5.9 % in April 2020.
And if that wasn’t sufficient, earlier this week, President Joe Biden banned imported Russian oil, acknowledging it should probably ship gasoline costs even larger. Biden stated he was dedicated to easing the strain on automobile homeowners, noting that extra oil might be launched from the emergency stockpiles to assist offset the associated fee.
However there are different issues individuals can do to ease the ache that doesn’t contain dashing from dealership to dealership on the lookout for that elusive EV. Within the Nineteen Seventies, within the midst of a gasoline disaster, round 20 % of People shared rides on the way in which to work. That quantity is round 7 % in the present day. Extra carpooling may very well be on the horizon.
The ’70s additionally noticed an explosion in bike gross sales, each because of excessive gasoline costs and the introduction of the 10-speed derailleur. Bike gross sales — particularly e-bike gross sales — soared throughout the pandemic, spurred by lockdown orders and a need for a secure, socially distanced strategy to get round.
A easy change in driving habits may additionally assist ease the ache. Autotrader’s Krebs advised reducing one’s driving speeds and consolidating errands into fewer journeys as among the many “ordinary gas-saving suggestions.”
You would additionally simply get a bus cross.

This wildfire evacuation alert accidentally went out to everyone in LA
After two days of dealing with wildfires that have burned thousands of acres, residents across Los Angeles County received a wildfire evacuation alert on Thursday afternoon that was a mistake. Shortly after, officials sent a follow-up alert saying that the notice was intended only for people near the Kenneth Fire in Woodland Hills.
Los Angeles County shared a message on X explaining what happened: “An evacuation order for residents near the Kenneth Fire currently burning in West Hills was mistakenly issued Countywide. This alert was only intended for residents of Calabasas and Agoura Hills.”
CBS News quotes a local official who said that the alert, which included a broken URL, was sent “due to a technical error.”
Many wildfires are burning in the LA area, and officials have confirmed at least six deaths, CNN reports. LA County has a population of nearly 10 million people, which is the “largest population of any county in the nation,” according to the county’s website.

Solar device transforms used tires to help purify water so that it's drinkable
Imagine a world where clean drinking water is readily available even in the most remote areas.
This vision is becoming a reality thanks to innovative research from scientists in Canada.
A team of scientists at Dalhousie University in Halifax, Nova Scotia, has developed a groundbreaking device that could revolutionize water desalination, offering hope to millions facing water scarcity worldwide.
I’M GIVING AWAY THE LATEST & GREATEST AIRPODS PRO 2
The power of plasmonic solar stills
At the heart of this innovation is a floating solar still, a device that harnesses the sun’s energy to purify seawater.
Dr. Mita Dasog, an associate professor of chemistry and Killam Memorial chair at Dalhousie, explains the science behind it: “Refractory plasmonic nanomaterials are very good at capturing light and converting that light into heat.”
This principle forms the foundation of their ingenious design. The solar still, conceptualized by Dr. Matthew Margeson during his Ph.D. studies, addresses challenges that have long plagued similar devices. It minimizes thermal losses, prevents salt buildup and can withstand harsh maritime conditions.
A BREAKTHROUGH GADGET COULD HELP YOU DETECT MICROPLASTICS IN YOUR DRINKING WATER
How it works
The floating solar still operates through an elegantly simple yet highly effective process. First, ocean water is drawn up to the device’s foam surface through a wicking system. Once the water reaches the surface, it is evaporated by solar-heated plasmonic materials. As the water vapor rises, the salt is left behind, ensuring that only purified water is collected. The vapor then recondenses on a clear plastic dome situated above the device. Finally, the purified water is funneled down the sides of the dome and collected in a sealed bag for easy access.
The results of this process are impressive. In real-world tests conducted in Halifax Harbour, the device produced up to 0.97 gallons of clean water daily, which was a record-breaking yield for passive floating solar stills.
WHAT IS ARTIFICIAL INTELLIGENCE (AI)?
AUTONOMOUS TRASH-GOBBLING ROBO BOAT WAGES WAR ON WATERWAY WASTE
Upcycling for sustainability
What sets this device apart is its use of unconventional materials. Instead of relying on expensive precious metals, the team turned to an unlikely source: used tires. Through a process called pyrolysis, carbon waste from tires is transformed into a crucial component of the desalination unit.
Dr. Dasog emphasizes the importance of accessibility: “We shouldn’t be making an expensive or very complicated device. It has to be easy to manufacture, last for a long time and be easy to take apart and move.” This approach not only makes the technology more affordable but also addresses the environmental issue of tire waste.
THE SHAPE-SHIFTING UNDERWATER ROBOT PIONEERING THE DEPTHS OF THE SEA
Affordable water purification and energy generation in one device
The device’s capabilities extend beyond water purification. It can simultaneously desalinate, disinfect and decontaminate water at a remarkably low cost: less than one cent per liter. It can also generate a small amount of thermoelectricity, potentially powering onboard water quality sensors.

Looking ahead
The team’s next step is to conduct further testing in South Asia, with the ultimate goal of making the device available worldwide. Dasog, nominated for the Emerging Leader award at the Water Canada Summit, envisions the device as a lifeline for communities displaced by war or climate change.
Kurt’s key takeaways
As we tackle the growing challenges of water security, innovations like the plasmonic solar still shine a light of hope. By blending cutting-edge science with sustainable materials, the researchers at Dalhousie University are doing more than just purifying water; they’re paving the way for a future that is both equitable and resourceful. This device not only makes clean drinking water accessible but also highlights how we can use renewable energy sources to address pressing global issues.
