A five-year study of solar farms planted with wildflowers and native grasses discovered that native bees showed a 20-fold increase in numbers.
Researchers at the US Department of Energy’s Argonne National Laboratory and National Renewable Energy Laboratory wanted to understand how insect pollinators respond to utility solar farms planted with native grasses and wildflowers.
They conducted the five-year field study because, surprisingly, there had previously been little field data available. The scientists collected data from two Enel Green Power North America solar farms in southern Minnesota built on retired agricultural land.
The two solar farms were planted with native grasses and wildflowers in early 2018. From August 2018 through August 2022, the researchers conducted 358 observational surveys for flowering vegetation and insect communities. Each time they visited, they evaluated changes in plant and insect abundance and diversity.
By the end of the field campaign, the team observed increases in all habitat and biodiversity metrics.

There was an increase in native plant species diversity and flower abundance. Total insect abundance tripled on the solar farm sites, and the team observed an increased diversity of native insect pollinators and agriculturally beneficial insects, including honeybees and native bees – which showed a 20-fold increase in numbers – butterflies, beetles, and more. Further, the insect pollinators visited soybean flowers in adjacent crop fields. Thriving pollinators make prime farmland more productive.
Lee Walston, an Argonne landscape ecologist, environmental scientist, and the study’s lead author, said, “[The study] demonstrates that, if properly sited, habitat-friendly solar energy can be a feasible way to safeguard insect populations and can improve the pollination services in adjacent agricultural fields.”
The researchers say their findings suggest two important implications: Habitat-friendly solar farms can play an essential role in conserving biodiversity and help mitigate land-use conflicts associated with the conversion of farmland for solar energy production.

Kenworth has announced the addition of Bendix’ Fusion advanced driver assist system (ADAS) to its line of options on the T680 line of Class 8 commercial semi trucks – a lineup that includes the Next Generation T680E battery electric semi truck.
One of the many new trucks revealed at the 2025 ACT Expo in Anaheim, California earlier this year, the Next Generation Kenworth T680E featured the latest advancements in battery-electric technology, an enhanced exterior design, and a suite of new, in-cab technology that extends to the addition of three Bendix Fusion version: ADAS, ADAS PRO, and ADAS PREMIER.
All three of the announced ADAS packages offer updated Adaptive Cruise Control (ACC) with ACC Stop and Auto Go™, a new Pedestrian Autonomous Emergency Braking (PAEB) feature, and a new High Beam Assist feature to reduce the likelihood of blinding oncoming drivers supported by the addition of a new forward-looking camera.
Those updates are in addition to the ADAS units Autonomous Emergency Braking (AEB), Multi-Lane Autonomous Emergency Braking, Highway Departure Braking (HDB), and Stationary Vehicle Braking (SVB), Lane Departure Warning, and Bendix® Blindspotter® Side Object Detection already available on previous versions of the ADAS-equipped Kenworth.

Now that we’ve got that acronym-loaded word-salad out of the way, we can get to the point: the newest generation of electric trucks is easier and safer to drive – and not just safer for the truck’s operators, but for the people who share the roads with them, too.

The Next-Generation T680E is available with up to 605 peak hp and 1,850 lb-ft of torque from a PACCAR Integrated ePowertrain fed from a 500 kWh li-ion battery pack good for more than 200 miles of loaded range. The updated Class 8 BEV is rated up to 82,000 lb. gross vehicle weight ratings (GVWR), and can get that load back up to speed quickly with a 350 kW peak charge rate that means the T680E can charge up to 90% in just two hours.
“This move to a fully integrated and ground-up PACCAR design means we were able to design for enhanced serviceability,” explains Joe Adams, Kenworth’s chief engineer. “Providing easier access to the Master Service Disconnects for improved safety and increased uptime and allowing the use of the DAVIE service tool for troubleshooting and diagnostics.”

Just like it says on the tin – retailers are advertising killer deals on the fun-to-drive Kia Niro EV, with one midwest auto dealer reporting more than $10,000 off the sticker price of the Niro EV Wind. That’s nearly 25% off the top line price!
The Kia Niro EV gets overshadowed by its objectively excellent EV6 and EV9 stablemates – both of which are currently available with substantial lease cash and 0% APR financing, in fact – but that doesn’t mean it’s not an excellent little electric runabout in its own right.
The last time I had a Niro EV tester, my kids loved it, I liked that it was quicker and more tossable than I expected it to be, and my wife liked the fact that “it doesn’t look electric. It looks normal.” And, with well over 200 miles of real world range (EPA-rated range is 253 miles), it was more than up to the task of commuting around Chicago and making the trip up to the Great Wolf Lodge in Gurnee and back without even needing to look for a charger.

It’s not the primary family hauler I’d choose – but as a second car? As a primary car for a slightly smaller family (1-2 kids, instead of 3-4)? The Kia Niro EV Wind, with a $42,470 MSRP, seems like a solid, “can’t go wrong” sort of choice. You know?
You won’t even have to pay that much, though. Raymond Kia in Antioch, Illinois is advertising a $42,470 Niro EV for $32,431 (that’s $10,039, or about 24% off the MSRP), and several others are advertising prices in the $33,000 range.

Many school districts who used EPA funding to help purchase Lion Electric school buses are now stuck with broken down or unsafe vehicles – but Lion’s new Canadian investors seemingly have no plans to make things right.
“All four Lion buses that we own are currently parked and not being used,” Coleen Souza, interim transportation director of Winthrop Public Schools, told Jay Traugott over at Clean Trucking. “Two of them are in need of repairs which would cost us money which we are not willing to invest in because the buses do not run for more than a month before needing more repairs.”
As bad as the revelations of safety and drivability issues and $250 million in unresolved debt have been, it’s the objectively stupid design choices that have been the most shocking.

“Lion built an auxiliary diesel heater to heat the bus, essentially writing the manual as they went,” explained a school superintendent in the midwest, who asked not to be named. “It was fascinating to watch but there were design flaws with the heater. For example, the intakes pointed downward and we’re driving across rural roads and the intake sucks in that dirt.”
“Using a diesel-powered heater to warm an electric bus also somewhat defeats the purpose of going 100% zero-emissions,” added Traugott.
Despite a new electric school bus rebate and a fresh cash injection from Vincent Chiara, president of Quebec real estate powerhouse Groupe MACH, and Lion director Pierre Wilkie, however, it seems like no help is coming.
It just gets worse and worse

The US school districts who spent tens of millions of taxpayer dollars in the hopes that Lion buses would help decarbonize their fleets and reduce students’ exposure to harmful diesel emissions? Many of them are back to using diesel, while others are trying to get their deposits back so they can buy something else.
