Offshore wind has significant potential to bring abundant, renewable power into homes and businesses in coastal communities. But wind power plant operators need solid information about conditions, such as wind speeds at various times of day, to confidently make sound investments in technology and wind plant locations. Such is the case for California, which is looking to add offshore wind to its power resources. In fall 2020, DOE’s PNNL partnered with WETO and the Bureau of Ocean Energy Management to deploy two offshore wind research buoys off the northern and central California coastlines — near Humboldt and Morro Bay, California, respectively.

Earlier this year, the buoy stationed near Humboldt was taken offline for some technical upgrades. A research team streamlined that buoy’s power use and incorporated more efficient data management capabilities.

The buoy also invited a new passenger on board.

Hitchin’ a Ride Is for the Birds (and Bats)

Enter ThermalTracker-3D, a technology developed by PNNL and supported by WETO. ThermalTracker-3D is designed to track bird (avian) and bat behaviors and attributes — such as flight height and speed — needed for assessing potential risks from offshore wind energy development.

The prototype technology, equipped with specialized software and a pair of thermal, stereovision cameras, hitched a ride on the Morro Bay buoy 20 miles off the coast of Humboldt County with the purpose of collecting information about seabird and bat activity. Paired with the buoy, avian and bat activity can be correlated with various weather and ocean conditions.

The Results Bob In

The yearlong deployment is ending in fall 2021 for the Morro Bay buoy, with those results starting to land in the team’s hands in real time.

“So far, we’ve noted a lot of variability in daily wind speed, especially in the upper part of the turbine rotor layer, at Morro Bay,” said Raghu Krishnamurthy, a PNNL Earth scientist who is analyzing the data. “We are also finding that the wind speed increased roughly one and a half times at night.”

At the Humboldt location off the northern coast, steady-state winds — winds that provide consistent power production during all hours of the day — are being observed at each altitude. These data will provide further insight about the minimum daily power production available from offshore wind power plants in California during all seasons.

The PNNL team continues to thoroughly analyze the buoy data as it comes in and will publish a technical report at the end of 2021.

ThermalTracker-3D also continues to pull in avian data — recording data continuously and transmitting the flight data to shore every hour. In its first 30 days at sea, the system recorded 699 flight tracks — the first time that continuous, “24/7” observations have been made in U.S. coastal waters.

Floating — and Flying — Into the Future

The Morro Bay buoy will also be recovered from the ocean and undergo similar upgrades as the Humboldt buoy, which will remain deployed until spring 2022. It will then take a tropical trip to the coast off Oahu, Hawaii, to support offshore wind energy planning for that state.

Meanwhile, once ThermalTracker-3D completes its first California stint, the research team plans to develop a system for potential future deployment on an offshore wind turbine. This effort will compare postconstruction seabird behavior with the baseline data collected off the buoy — completing the understanding of how seabirds are affected by offshore wind energy development.

The data from the buoy and ThermalTracker-3D deployments will be available to the wind energy research community on the Data Archive and Portal, which is managed by PNNL. In August, R&D World Magazine announced that ThermalTracker-3D is a finalist for an R&D 100 award in the Software/Services category; winners will be announced later this year.

Homeowners share surprising, real-world data after installing solar panels

Homeowners share surprising, real-world data after installing solar panels

Are you wondering what kind of results you’d get if you added a home solar system to your roof? Homeowners are sharing their results online — and the real-world data might surprise you!

In a recent post to r/Solar, a Reddit user going by DontBuyBitcoin shared a screenshot indicating that their newly-installed ~11.5 kW system produced over 1,700 kWh of electricity in October. “Pretty surprised by the production of the system I got,” writes DontBuyBitcoin. “11.48KW. I cant wait to see what JUNE-AUGUST [2026] going to look like 😍 I wish SolarEdge will make their app better looking with more functionality”

Other Redditors were quick to share in the enthusiasm. “Congratulations!!! Great numbers,” wrote LegalNet4337. “We got 1.6 MWh with a 14.45 kW system. East and West facing panels in SoCal.”

That 1,700 kWh is nothing to sneeze at. Based on the current national average electricity price of about $0.17/kWh (in AUG2025), DontBuyBitcoin’s admittedly large-ish system translates to ~$290 of potential savings. In a higher rate state like Illinois, with a projected 2026 kWh rate that’s closer to $0.18/kWh, that’s ~$306/mo.

We expect retail electricity prices to residential customers will average 17 cents per kilowatthour (kWh) nationwide in 2025, a 4% increase over 2024, and then rise to approximately 18 cents/kWh in 2026. This rise continues a trend in which residential electricity prices have increased at an average annual rate of 5% each year since the COVID-19 pandemic. The increase in retail electricity prices this year comes as the cost of natural gas to the electric power sector was up more than 40% in 1H25 compared with a year earlier, with similar year-over-year increases forecast for the remainder of 2025. The average cost of natural gas for power generation in our forecast increases another 17% in 2026.

US ENERGY INFORMATION ADMINISTRATION (EIA)

Those are big numbers, but 11-15 kW rooftop solar systems are big. Significantly bigger, in fact, than the US average, ~6.6 kW in 2024 – but you don’t have to have a big system in order to post big numbers. Superior weather conditions and perfect PV panel placement can also get the job done, as another Redditor found.

“The last 2 days we have had perfect weather here in South Florida and I have been able to get over 30 kWh from a 5 kW system with a 3.8 kW inverter. This is the highest I have seen since getting PTO in September,” wrote Redditor dlewis23, who shared another SolarEdge graph. “I am super happy with seeing over 30 kWh in a single day.”

30 kW/day from home solar


Taken altogether, these real-world snapshots prove that whether it’s a modest 5 kW array or a beefy 10+ kW setup, homeowners out in the real world are seeing meaningful, measurable differences from their home solar installations. And, with retail electricity prices projected to keep on rising through the decade, every kilowatt counts.

Electrek’s Take


From Electrek SEP2025 survey.

When we ran our “Why did you choose to go solar?” survey back in September, only 32.6% of respondents chose, “Lowering my monthly utility bills” as their primary motivation to go solar. That result proved, in my mind, that Electrek readers are just better people than most, and seem to be willing to spend a little more to do something positive for their environment and their community.

That said, wasn’t it no less a thinker than Albert Einstein who said, “Compound interest is the most powerful force in the universe” (Google it.)? And, with a 5% rate hike compounding every year from now until the AI and data center bubbles burst, the impact energy rates may have on all our pocketbooks may be enough to put “Lowering my monthly utility bills” back on top.

If and when that happens: be smart, get several quotes, and understand the difference between buying and leasing your PV system (especially if you plan on selling your home in the foreseeable future).

Volvo set to ditch LiDAR for 2026 – and Luminar is BIG mad

Volvo set to ditch LiDAR for 2026 – and Luminar is BIG mad

It seems like the writing was already on the wall last week when Volvo moved to make its Luminar-supplied LiDAR system an option – there are now reports that the Swedish car brand is set to ditch LiDAR tech entirely in 2026.

In a recent SEC filing following a missed interest payment on its 2L notes, Luminar confirmed that Volvo’s new ES90 and EX90 flagship models (along with the new Polestar 3) would no longer be offered with LiDAR from Luminar. The move signals a full reversal on the safety tech that had started as standard equipment, then became an option, and is now (according to reports from CarScoops) gone altogether.

In a statement, a Volvo Cars USA spokesperson added the decision was reportedly made, “to limit the company’s supply chain risk exposure, and it is a direct result of Luminar’s failure to meet its contractual obligations to Volvo Cars.”

This is what Luminar had to say about the current, icy state of the two companies’ relationship as of the 31OCT filing:

The Company’s largest customer, Volvo Cars (“Volvo”), has informed us that, beginning in April 2026, Volvo will no longer make our Iris LiDAR standard on its EX90 and ES90 vehicles (although Iris will remain an option). Volvo also informed the Company that it has deferred the decision as to whether to include LiDAR, including Halo (Luminar’s next generation LiDAR under development), in its next generation of vehicles from 2027 to 2029 at the earliest. As a result of these actions, the Company has made a claim against Volvo for significant damages and has suspended further commitments of Iris LiDAR products for Volvo pending resolution of the dispute. The Company is in discussions with Volvo concerning the dispute; however, there can be no assurance that the dispute will be resolved favorably or at all. Furthermore, there can be no guarantee that any claim or litigation against Volvo will be successful or that the Company will be able to recover damages from Volvo.

As a result of the foregoing, the Company is suspending its guidance for the fiscal year ending December 31, 2025.

LUMINAR

On November 14, Luminar confirmed that Volvo had terminated its contract altogether, in a blow that could leave Luminar rethinking its long-term future and planning litigation against its biggest ex-customer.

The news follows a host of significant upgrades to the EX90 that include a new, more dependable electronic control module (ECM) and 800V system architecture for faster charging and upgraded ADAS that improves the automatic emergency steering functions and Park Pilot assistant.

Electrek’s Take


You can’t spend years telling everyone you’re miles ahead because you have LiDAR, then ditch LiDAR, and pretend no one is going to call you out on it. They had better hope they don’t up on Mark Rober’s YouTube channel doing a Wile E. Coyote impression (above).

That said, it’ll be interesting to see if ditching the LiDAR has a negative impact there. Or, frankly, whether ditching the LiDAR and its heavy compute loads will actually help mitigate some of the EX90’s niggling software issues. It could go either way, really – and I’m not quite sure which it will be. Let us know which way you think it’ll go in the comments.

John Deere electric riding mower gets removable batteries from EGO

The new John Deere Z370RS Electric ZTrak zero turn electric riding mower promises all the power and performance Deere’s customers have come to expect from its quiet, maintenance-free electric offerings – but with an all new twist: removable batteries.

The latest residential ZT electric mower from John Deere features a 42″ AccelDeep mower deck for broad, capable cuts through up to 1.25 acres of lawn per charge, which is about what you’d expect from the current generation of battery-powered Deeres – but this is where the new Z370RS Electric ZTrak comes into its own.

Flip the lid behind the comfortably padded yellow seat and you’ll be greeted by six (6!) 56V ARC Lithium batteries from electric outdoor brand EGO. Those removable batteries can be swapped out of the Z370RS for fresh ones in seconds, getting you back to work in less time than it takes to gravity pour a tank of gas.

And, because they’re EGO batteries, they can be used in any 56V-powered EGO-brand tools and minibikes for unprecedented cross-brand interoperability. Tools and minibikes that, it should be noted, can be purchased at John Deere dealers across the country.

The upsell scripts write themselves, kids. And when you start your dialing, tell your prospective customers their new Z370RS Electric ZTrak electric mower lists for $6,499, and if you order now we can bundle it with EGO minibike for the kiddos – just in time for the holidays!

Electrek’s Take


When John Deere launched the first Z370R, Peter Johnson wrote that electrifying lawn equipment needs to be a priority, citing EPA data that showed gas-powered lawnmowers making up five percent of the total air pollution in the US (despite covering far less than 5% of the total miles driven on that gas). “Moreover,” he writes, “it takes about 800 million gallons of gasoline each year (with an additional 17 million gallons spilled) to fuel this equipment.”

It should go without saying, then, that states like California, which are banning small off-road combustion engines, have the right idea.
