From Iceland to Alaska to France, NREL geoscientist Amanda Kolker has studied geothermal energy all around the world. After graduating with a bachelor’s degree in geology, Kolker went to study volcano and glacier interactions in Iceland but was quickly distracted by Iceland’s vast geothermal energy systems.

As an earth scientist, climate change has been on Kolker’s radar for most of her life, so studying geothermal energy was the perfect combination of her interest in earth science and passion for tackling climate change. Now at NREL, Kolker has brought her global perspective to help improve our understanding of geothermal resources and expand our utilization of those resources such as for heating and cooling.

Bringing Lessons Learned to NREL

After her travels, Kolker came to NREL to continue combining her passions for geothermal energy and tackling climate change. Kolker has worked on a variety of projects ranging from resource assessments to techno-economic analysis of geothermal district heating systems.

Now, Kolker is working on an exciting new international project, working with partners in Iceland and four other European countries to explore “supercritical” energy resources and systems and apply lessons learned to demonstration sites in Iceland and Oregon. Because supercritical resources may be able to produce 10 times the amount of energy from one well as a typical geothermal plant, it would be extremely beneficial to tap into these resources.

Looking Beyond Iceland

Kolker dedicated the next phase of her career to exploring for geothermal resources, earning a Ph.D. from the University of Alaska. There, she helped develop the lowest-temperature geothermal resource in the world for a combined heat and power microgrid in Alaska.

That system uses one resource to generate electricity, heat greenhouses and log cabins, and cool an ice museum. Her Ph.D. research and subsequent consulting work focused on looking at replicating that approach at other geothermal systems near remote communities in Alaska with high costs of power, high costs of heat, and low energy resilience.

Many years later, Kolker moved to France and witnessed how lower temperature geothermal resources were used for agriculture, industry, and to heat and cool districts. Many European and Asian countries use shared heating and cooling systems; studying these French systems helped Kolker bring key lessons back to the United States.

“If we want to better utilize the vast potential of geothermal energy in the United States, we need a bit of a paradigm shift,” Kolker said. “Renewable heating and cooling technologies should be given the same degree of attention as renewable electricity technologies, as heating and cooling accounts for up to 40% of U.S. energy demand. That demand is still mostly met by combustion of fossil fuels, producing temperatures well above what is typically needed.”

Leveraging Industry Partnerships

Assessing characterization and use of earth’s subsurface resources, she is keeping an eye on the relationship between the fossil fuel and geothermal sectors, as oil and gas companies have useful subsurface data that the geothermal energy sector needs.

She has seen how government involvement in countries like Japan, France, and Iceland have pushed geothermal heat and power projects through to development, and Kolker is excited to see how DOE will continue to help push geothermal energy research to take off even more.

From her global travels, Kolker has been inspired by several things, including:

  • Collaborations among subsurface industries
  • Governments taking on risks
  • Focusing heavily on heating and cooling
  • Geothermal Combined heat-and-power (CHP) microgrids for energy resilience.

Notably, Kolker was highlighted in DOE’s Women in Energy series and recently published 2021 U.S. Geothermal Power Production and District Heating Market Report, along with her co-authors.

MAN electric semi truck gets real as series production begins

MAN electric semi truck gets real as series production begins

MAN Trucks are always good for a headline, but despite the company’s pro-battery bluster they’ve barely managed to get 200 battery electric semi trucks on the road … until now that is: the company announced that series production of its heavy-duty eTruck prime mover is officially underway!

We’ve been huge fans of MAN Trucks’ CEO Alexander Vlaskamp since last year, when he had the courage to explain a simple truth: that it’s impossible for hydrogen to effectively compete with battery electric when it comes to a viable fuel for transportation.

Since then, we’ve talked a bit about MAN’s early BEV customers — but with just 200 trucks on the road, they’ve been few and far between. That’s all set to change now that MAN Executive Board Member for Production Michael Kobriger, together with Manfred Weber, Member of the European Parliament and Chairman of the EPP, gave the go-ahead to start the eTruck production line at the company’s Munich plant.

From now on, both electric and diesel trucks will be produced in a fully integrated mixed production process on the same line, with enough capacity to produce up to 100 eTrucks per day. (!)

 “The start of series production of our electric trucks is historic. It marks a turning point in our history,” explains Vlaskamp, enthusiastically. “The future of MAN begins now, at this very moment. The entire MAN team is proud to be actively shaping the transformation from diesel to electric drive. Our highly efficient electric trucks will make locally emission-free freight transport a reality. This is an enormously important step towards achieving our goal of becoming CO2-neutral by 2050. The fact that we can manufacture the electric trucks on the same production line as our state-of-the-art diesel trucks also gives us enormous flexibility and increases production efficiency.”

MAN says the plant’s maximum capacity is 100 trucks per day, citing about 8 hours to produce one of its heavy-duty semis. The interesting thing, though, is that it doesn’t seem to matter whether those 100 trucks are diesel- or battery-powered.

Flexible assembly


“The production of electric or diesel trucks on a single line can be flexibly adapted to market developments, and the vehicles can be built exactly in the order in which they are ordered by customers. This innovative concept is accompanied by extensive changes along the assembly line as well as in the supply chain and logistics,” says Kobriger, citing that while ICE trucks are initially fitted with axles, tanks and exhaust systems, the electric models are instead fitted with two batteries under the cab together with a “power pack” of electrical components.

All 5,000+ Munich-plant MAN employees have been trained in high-voltage technology in preparation for this “transformation” of the facility. The company says it has 700 of its 740 km (about 450 mile) battery electric trucks already sold, with more sales sure to come as availability ramps up to meet demand.

Electrek’s Take


Historic: MAN starts series production of electric trucks
Historic: eTruck production begins; via MAN.

Betting against Tesla has been bad business for well over a decade now, but with MAN now capable of putting out about as many electric semi trucks in a single day as Tesla has in the last ::checks notes:: eight years since the official launch of the Tesla Semi concept, it’s hard to imagine them catching up — and harder still to see them catching up with Volvo or Renault, each of who have logged tens of millions of electric semi miles in recent years.

That said, Tesla has beaten legacy brands with massive, seemingly insurmountable leads before – but the good news is that, when it comes to EVs, whoever wins, we kind of all win, you know? Even Elon! That’s my take, anyway. Head down to the comments and let me know yours.

NYC creates new department to hassle e-bike delivery riders

NYC creates new department to hassle e-bike delivery riders

New York City is creating a new department aimed at cracking down on e-bike delivery workers, and critics say it’s the latest move in a growing pattern of targeting micromobility riders instead of the real threats on the road.

Buried inside NYC’s new $116 billion city budget is a plan to hire 45 new unarmed peace officers tasked with enforcing laws against delivery cyclists, particularly those riding e-bikes and mopeds. The new officers will work under the just-announced Department of Sustainable Delivery, a division of the Department of Transportation set to deploy in 2028.

Mayor Eric Adams says the department will help improve street safety and hold delivery app companies accountable for the pressure they put on gig workers. “The newly created Department of Sustainable Delivery is yet another step that we’re taking to support delivery workers, keep pedestrians safe, and hold delivery app companies accountable for placing unrealistic expectations on their workers that put New Yorkers in harm’s way,” Adams explained in a published statement.

But the move is already raising red flags among advocates for delivery workers and cycling safety, who warn that these efforts could lead to increased surveillance and policing of low-income, often immigrant workers, many of whom already operate under grueling conditions just to make ends meet.

The officers will be trained to issue moving violations and enforce commercial cycling laws, though city officials haven’t clarified exactly how they’ll distinguish between a reckless rider and one simply hustling to meet the often unrealistic delivery windows imposed by apps like Uber Eats, DoorDash, and Grubhub.

While Adams frames the effort as a safety initiative, critics argue it’s another example of micromobility scapegoating. Just last month, he imposed a 15 mph speed limit on e-bikes across the city, in a move that advocates say ignores the realities of urban riding and fails to address the vastly greater danger posed by cars and trucks. The administration also moved to undo a redesign of Bedford Avenue in Brooklyn, rolling back a protected bike lane project that city data showed had improved safety.

Delivery riders in NYC, many of whom are immigrants working long shifts in all weather conditions, overwhelmingly use e-bikes to cover more ground, more quickly. These workers have been essential to the city’s economy, especially during the COVID-19 pandemic. Yet they continue to face increasing scrutiny from law enforcement, often for minor infractions, even as drivers of multi-ton vehicles are rarely held to the same standard.

City Council spokesperson Mara Davis acknowledged the concerns, stating, “There are always concerns about any new policy that could give way to discriminatory policing of delivery workers and immigrants. We remain in discussions with advocates and constructive members of the mayoral administration to advance solutions on e-bike safety, sustainable delivery, and street safety.”

Despite the rhetoric about safety, the data paints a different picture. City statistics show that e-bikes account for less than 4% of traffic-related injuries, and Gothamist pointed out that only six pedestrian fatalities involving e-bike riders were reported between 2021 and 2024. Meanwhile, cars and trucks continue to kill hundreds of New Yorkers every year. But rather than increasing enforcement on reckless drivers or investing more in safe bike infrastructure, the city is spending taxpayer money to police bicycles.

Electrek’s Take

In a city desperately trying to transition to more sustainable forms of transportation, I just don’t think that increasing pressure on the people doing the most riding is the answer. Delivery workers are part of the solution to car dependence, not the problem.

If NYC wants cleaner, safer streets, the focus should be on supporting these riders with safe infrastructure, affordable bikes, and better labor protections – not treating them like traffic scofflaws. Yes, enforcement is important. And yes, dangerous riders should be penalized to the full extent of the law, especially when they pose a real threat to pedestrians. But let’s not pretend like that’s what this about. If we cared about pedestrian safety, we’d be increasing enforcement to prevent the hundreds killed every year by cars in NYC – not the two pedestrians killed by e-bikes.

BYD is the first to unlock L4 smart parking and it comes with a surprise guarantee

China’s EV leader, BYD, just reached another major breakthrough: its smart parking feature now offers L4 autonomy. To sweeten the deal, BYD says it will fully cover any losses associated with the new feature.

BYD becomes the first to achieve L4 smart parking

BYD said it was coming soon. Earlier this week, BYD posted on Weibo that it’s about to launch “the largest-scale smart driving OTA in history.”

On Wednesday, BYD confirmed that its smart parking system now offers L4 autonomy, becoming the first to achieve the feat. In a statement, the company said, “BYD is the first to achieve L4-level smart parking, and the official promise is to provide a safety guarantee​​​.”

The company is also pledging to cover any losses tied to the feature. Instead of going through their insurance company, drivers can contact BYD’s after-sales team to handle the incident.

All BYD vehicles equipped with its God’s Eye smart driving system can get the upgrade. Earlier this year, the EV maker upgraded 21 of its best-selling vehicles with its God’s Eye system, at no additional cost.

The breakthrough comes after BYD announced earlier this week that there are now over 1 million vehicles on the road with its God’s Eye smart driving system. With L4 smart parking, the vehicle can operate without human interaction under certain conditions.

And that’s not all. BYD also said it’s pushing new OTA updates for its God’s Eye B and C systems. God’s Eye B will gain new functions, including multiple U-turns, detours, and a three-speed parking feature. Meanwhile, God’s Eye C is set to receive front parking and lane change reminders.

BYD’s smart driving system has three levels: A, B, and C. The A system is primarily reserved for the ultra-luxury Yangwang brand, while B is used for Denza and some premium BYD brand models. The God’s Eye C system is used for lower-cost BYD vehicles, such as the Seagull EV, its top seller in China.
