The US Department of Energy (DOE) has released an encouraging new report revealing that 90% of wind turbine materials are already recyclable using existing infrastructure, but tackling the remaining 10% needs innovation.

That’s why the Biden administration’s Bipartisan Infrastructure Law has allocated over $20 million to develop technologies that address these challenges.

Why this matters

The wind energy industry is growing rapidly, but questions about what happens to turbines at the end of their life are critical. Recyclable wind turbines means not only less waste but also a more affordable and sustainable energy future.

According to Jeff Marootian, principal deputy assistant secretary for the Office of Energy Efficiency and Renewable Energy, “The US already has the ability to recycle most wind turbine materials, so achieving a fully sustainable domestic wind energy industry is well within reach.”

The report, titled, “Recycling Wind Energy Systems in the United States Part 1: Providing a Baseline for America’s Wind Energy Recycling Infrastructure for Wind Turbines and Systems,” identifies short-, medium-, and long-term research, development, and demonstration priorities along the life cycle of wind turbines. Developed by researchers at the National Renewable Energy Laboratory, with help from Oak Ridge and Sandia National Laboratories, the findings aim to guide future investments and technological innovations.

What’s easily recyclable and what’s not

The bulk of a wind turbine – towers, foundations, and steel-based drivetrain components – is relatively easy to recycle. However, components like blades, generators, and nacelle covers are tougher to process.

Blades, for instance, are often made from hard-to-recycle materials like thermoset resins, but switching to recyclable thermoplastics could be a game changer. Innovations like chemical dissolution and pyrolysis could make blade recycling more viable in the near future.

Critical materials like nickel, cobalt, and zinc used in generators and power electronics are particularly important to recover.

Key strategies for a circular economy

To make the wind energy sector fully sustainable, the DOE report emphasizes the adoption of measures such as:

  • Better decommissioning practices – Improving how turbine materials are collected and sorted at the end of their life cycle.
  • Strategic recycling sites – Locating recycling facilities closer to where turbines are decommissioned to reduce costs and emissions.
  • Advanced material substitution – Using recyclable and affordable materials in manufacturing.
  • Optimized material recovery Developing methods to make recovered materials usable in second-life applications.

Looking ahead

The DOE’s research also underscores the importance of regional factors, such as the availability of skilled workers and transportation logistics, in building a cost-effective recycling infrastructure. As the US continues to expand its wind energy capacity, these findings provide a roadmap for minimizing waste and maximizing sustainability.

California hits back as CARB takes legal action against truck brands

California hits back as CARB takes legal action against truck brands

Following a lawsuit brought against the California Air Resources Board (CARB) by major heavy truck manufacturers over California’s emissions requirements, CARB has struck back with fresh lawsuit of its own alleging that the manufacturers violated the terms of the 2023 Clean Truck Partnership agreement to sell cleaner vehicles.

Daimler Truck North America, International Motors, Paccar and Volvo Group North America sued the California Air Resources Board in federal court this past August, seeking to invalidate the Clean Truck Partnership emissions reduction deal they signed with the state in 2023 to move away from traditional trucks and toward zero-emission vehicles (ZEVs). The main point of the lawsuit was that, because the incoming Trump Administration rolled back Environmental Protection Agency (EPA) policies that had previously given individual states the right to set their own environmental and emissions laws, the truck makers shouldn’t have to honor the deals signed with individual states.

“Plaintiffs are caught in the crossfire: California demands that OEMs follow preempted laws; the United States maintains such laws are illegal and orders OEMs to disregard them,” the lawsuit reads. “Accordingly, Plaintiff OEMs file this lawsuit to clarify their legal obligations under federal and state law and to enjoin California from enforcing standards preempted by federal law.”

After several weeks of waiting for a response, we finally have one: CARB is suing the OEMs right back, claiming that the initial suit proves the signing manufacturers, “(have) unambiguously stated that they do not intend to comply.”

In its lawsuit, CARB argues that monetary damages alone would not make the people of the State of California whole as far as damages are concerned, citing that the stated goal of the 2023 Clean Truck Partnership was, “to achieve emissions reductions that cannot be measured strictly in financial terms,” according to ACT-News.

The agency is asking the court to compel the truck companies to perform on their 2023 obligations or, failing that, to allow CARB to rescind the contract and recover its costs. A hearing on the truck makers’ request for a preliminary injunction was held Friday, with another court date set for November 21, when CARB will seek to dismiss the case brought forth by the truck brands. The outcome of these cases could shape how state and federal government agencies cooperation on emissions rules in the future.

New national law will turn large parking lots into solar power farms

New national law will turn large parking lots into solar power farms

Starting this month, parking lots in South Korea with more than 80 spaces will be required to install solar canopies and carports. But, unlike similar laws that have been proposed in the US, this new law doesn’t just apply to new construction – existing lots will have to comply as well!

South Korea’s Ministry of Trade, Industry and Energy announced in August that it has prepared an amendment to the Enforcement Decree of the Act on the Promotion of the Development, Use, and Diffusion of New and Renewable Energy to the effect that all publicly- and privately-owned parking lots in the Asian country with room for more than 80 vehicles will be compelled to add solar panels to their lots in a move designed to proactively expand renewable energy and create more solar and construction jobs.

In addition to creating jobs and working to stabilize the local grid with more renewable energy, the proposed solar canopies will offer a number of practical, day-to-day benefits for Korean drivers, as well.

The shaded structures will protect vehicles from heavy rain, snow, and the blistering summer sun — keeping interiors cooler, extending the life of plastics and upholstery, and even helping to preserve battery range in EVs and PHEVs by reducing their AC loads (and, of course, provide charging while the cars are parked).

To their credit, Ministry officials absolutely get it. “Through this mandatory installation,” one unnamed official told Asia Business Daily, “we expect to expand the distribution of eco-friendly renewable energy generation facilities while providing tangible benefits to the public. By utilizing idle land such as parking lots, we can maximize land use efficiency. In addition, installing canopy-type solar panels can provide shade underneath, offering noticeable comfort to people using parking lots during hot weather.”

The new rule was approved in late September, and is expected to go into effect later this month, with new installation projects set to begin immediately.

South Korea is proving that an idea like is practical. Here in the US, we’re proving that out, too – the Northwest Fire District in Arizona partnered with Standard Solar to build a conceptually similar, 657 kW solar carport system across 12 parking lots (shown, above) that delivers more than 1.23 million kWh of clean, emissions-free power annually and offsets the equivalent of 185,000 vehicles’ worth of harmful carbon emissions.

That’s just Arizona. In New York, a new initiative to help expand solar into parking lots has more than doubled commercially zoned land where EV charging stations can be sited, “freeing up” an additional 400 million square feet of space throughout the city. 

Sun-rich states like Texas, New Mexico, and Florida could also benefit, and even if we’re “just” adding fresh energy sources to municipal parking, dealer lots, and public schools, we could do a lot to reduce the cost of energy generation for the entire community. And, for what it’s worth, that seems to be right in line with the big reasons why people are choosing to add solar to their homes today.

What do you guys think – would something like this work in the US, or are we too far gone down the sophomoric, pseudo-libertarian rabbit hole to ever dig our way out? Let us know your take in the comments.

NHTSA is investigating Waymo robotaxis for passing stopped school bus

NHTSA is investigating Waymo robotaxis for passing stopped school bus

Autonomous taxi company Waymo faced scrutiny last month when a car was caught on video illegally passing a stopped school bus that was letting children off in Atlanta. Now, the National Highway Traffic Safety Administration (NHTSA) is looking into it.

Georgia State Representative Clint Crowe seemed stunned after being presented with video of a Waymo driverless car illegally passing a stopped school bus on Briarcliff Road in Atlanta last month. “I’m a big fan of new technologies and emerging technologies and I think that driverless cars are going to become more prevalent,” he told local NBC news affiliate WBIR. “But we got [sic] to think about how they’re going to comply with the law.”

WBIR | Waymo illegally passes school bus


Crowe co-sponsored Addy’s Law in 2024. The legislation was named after 8-year-old Addy Pierce, who was killed in Henry County after being struck while crossing the street to get to her bus. The law stiffened penalties for illegally passing a stopped school bus, carrying penalties of up to $1,000 in fines and even jail time.

According to Crowe, those rules still apply to autonomous vehicles. “The majority of our traffic laws, the penalty is usually a fine and or driver’s license suspension. These cars don’t have a driver, so they don’t have a driver’s license and so we’re really going to have to rethink who’s the responsible party, who’s going to be responsible for being in control of that vehicle and who’s going to be the operator of that vehicle,” he said.

Crowe believes manufacturers should face stronger consequences when their vehicles break the law, saying the $1,000 fine doesn’t go far enough.

WBIR NEWS

Now, thanks to pressure from social media and politicians like Crowe and Geoirgia State Senator Rick Williams, who helped co-author Addy’s Law, it seems like NHTSA is getting involved.

Prompted by media reports, the US Department of Transportation issued an investigation regarding Waymo’s AV, which states that, “the AV initially stopped, but then drove around the front of the bus by briefly turning right to avoid running into the bus’s right front end, then turning left to pass in front of the bus, and then turning further left and driving down the roadway past the entire left side of the bus. During this maneuver, the Waymo AV passed the bus’s extended crossing control arm near disembarking students (on the bus’s right side) and passed the extended stop arm on the bus’s left side.”

While it remains to be seen how much work NHTSA is actually doing amid the ongoing shutdown of the Federal government, it’s worth noting that, regardless of the outcome, Senator Williams said he plans to introduce new legislation that would hold driverless car companies accountable with higher fines if their vehicles violate traffic laws. If that passes in Georgia, it could set the stage for politicians across the US and even abroad to use similar fins to halt the spread of autonomous taxis in their states.

Driverless cars should be stopped until it can be figured out,” said Williams. “We should not have this on the road. It’s too dangerous for our children.”

You can read NHTSA summary, below.

We’re typically pretty tech- and autonomous-forward here, but as a parent I would absolutely lose my s*** if a Waymo or Robotaxi or whatever else ran over my kid. but I’ve also seen plenty of human drivers blow past a school bus with a knee on the steering wheel and both eyes glued firmly to their phones. Let us know who you’d be more ready to trust with your kids’ lives in the comments.
