Uranium Critical Mineral Reclassification signals a US executive order directing USGS to restore critical status, boosting nuclear energy, domestic uranium mining, streamlined permitting, federal support, and energy security amid import reliance and supply chain risks.

Key Points

A policy relisting uranium as a critical mineral to unlock funding, speed permits, and strengthen U.S. nuclear security.

✅ Directs Interior to have USGS reconsider uranium classification

✅ Speeds permits for domestic uranium mining projects

✅ Targets import dependence and strengthens energy security

In a strategic move to bolster the United States' nuclear energy sector, former President Donald Trump issued an executive order on January 20, 2025, directing the Secretary of the Interior to instruct the U.S. Geological Survey (USGS) to reconsider classifying uranium as a critical mineral. This directive aims to enhance federal support and streamline permitting processes for domestic uranium projects, thereby strengthening U.S. energy security objectives.

Reclassification of Uranium as a Critical Mineral

The USGS had previously removed uranium from its critical minerals list in 2022, categorizing it as a "fuel mineral" that did not qualify for such designation. The recent executive order seeks to reverse this decision, recognizing uranium's strategic importance in the context of the nation's energy infrastructure and geopolitical considerations.

Implications for Domestic Uranium Production

Reclassifying uranium as a critical mineral is expected to unlock federal funding and expedite the permitting process for uranium mining projects within the United States. This initiative is particularly pertinent given the significant decline in domestic uranium production over the past two decades. According to the U.S. Energy Information Administration, domestic production has decreased by 96%, from 4.8 million pounds in 2014 to approximately 121,296 pounds in the third quarter of 2024.

Current Uranium Supply Dynamics

Despite the push for increased domestic production, the U.S. remains heavily reliant on uranium imports. In 2022, 27% of U.S. uranium purchases were sourced from Canada, with an additional 57% imported from countries including Kazakhstan, Uzbekistan, Australia, and Russia; a recent ban on Russian uranium could further disrupt these supply patterns and heighten risks. This reliance on foreign sources has raised concerns about energy security, especially in light of recent geopolitical tensions.

Challenges and Considerations

While the executive order represents a significant step toward revitalizing the U.S. nuclear energy sector, several challenges persist, and energy dominance faces constraints that will shape implementation:

• Regulatory Hurdles: Accelerating the permitting process for uranium mining projects involves navigating complex environmental and regulatory frameworks, though recent permitting reforms for geothermal hint at potential pathways, which can be time-consuming and contentious.

• Market Dynamics: The uranium market is subject to global supply and demand fluctuations, and domestic producers may face competition from established international suppliers.

• Infrastructure Development: Expanding domestic uranium production necessitates substantial investment in mining infrastructure and workforce development, areas that have been underfunded in recent years.

Broader Implications for Nuclear Energy Policy

The executive order aligns with a broader strategy to revitalize the U.S. nuclear energy industry, where ongoing nuclear innovation is critical to delivering stable, low-emission power. The increasing demand for nuclear energy is driven by the global push for zero-emissions energy sources and the need to support power-intensive technologies, such as artificial intelligence servers.

Former President Trump's executive order to reclassify uranium as a critical mineral, aligning with his broader energy agenda and a prior pledge to end the 'war on coal', signifies a pivotal moment for the U.S. nuclear energy sector. By potentially unlocking federal support, including programs advanced by the Nuclear Innovation Act, and streamlining permitting processes, this initiative aims to reduce dependence on foreign uranium sources and enhance national energy security. However, realizing these objectives will require addressing regulatory challenges, market dynamics, and infrastructure needs to ensure the successful revitalization of the domestic uranium industry.

Attosecond Electron Transport uses ultrafast lasers and single-cycle light pulses to drive tunneling in bowtie gold nanoantennas, enabling sub-femtosecond switching in optoelectronic nanostructures and surpassing picosecond silicon limits for next-gen computing.

Key Points

A light-driven method that manipulates electrons with ultrafast pulses to switch currents within attoseconds.

✅ Uses single-cycle light pulses to drive electron tunneling

✅ Achieves 600 attosecond current switching in nano-gaps

✅ Enables optoelectronic, plasmonic devices beyond silicon

When it comes to data transfer and computing, the faster we can shift electrons and conduct electricity the better – and scientists have just been able to transport electrons at sub-femtosecond speeds (less than one quadrillionth of a second) in an experimental setup.

The trick is manipulating the electrons with light waves that are specially crafted and produced by an ultrafast laser. It might be a long while before this sort of setup makes it into your laptop, but similar precision is seen in noninvasive interventions where targeted electrical stimulation can boost short-term memory for limited periods, and the fact they pulled it off promises a significant step forward in terms of what we can expect from our devices.

Right now, the fastest electronic components can be switched on or off in picoseconds (trillionths of a second), a pace that intersects with debates over 5G electricity use as systems scale, around 1,000 times slower than a femtosecond.

With their new method, the physicists were able to switch electric currents at around 600 attoseconds (one femtosecond is 1,000 attoseconds).

"This may well be the distant future of electronics," says physicist Alfred Leitenstorfer from the University of Konstanz in Germany. "Our experiments with single-cycle light pulses have taken us well into the attosecond range of electron transport."

Leitenstorfer and his colleagues were able to build a precise setup at the Centre for Applied Photonics in Konstanz. Their machinery included both the ability to carefully manipulate ultrashort light pulses, and to construct the necessary nanostructures, including graphene architectures, where appropriate.

The laser used by the team was able to push out one hundred million single-cycle light pulses every single second in order to generate a measurable current. Using nanoscale gold antennae in a bowtie shape (see the image above), the electric field of the pulse was concentrated down into a gap measuring just six nanometres wide (six thousand-millionths of a metre).

As a result of their specialist setup and the electron tunnelling and accelerating it produced, the researchers could switch electric currents at well under a femtosecond – less than half an oscillation period of the electric field of the light pulses.

Getting beyond the restrictions of conventional silicon semiconductor technology has proved a challenge for scientists, but using the insanely fast oscillations of light to help electrons pick up speed could provide new avenues for pushing the limits on electronics, as our power infrastructure is increasingly digitized and integrated with photonics.

And that's something that could be very advantageous in the next generation of computers: scientists are currently experimenting with the way that light and electronics could work together in all sorts of different ways, from noninvasive brain stimulation to novel sensors.

Eventually, Leitenstorfer and his team think that the limitations of today's computing systems could be overcome using plasmonic nanoparticles and optoelectronic devices, using the characteristics of light pulses to manipulate electrons at super-small scales, with related work even exploring electricity from snowfall under specific conditions.

"This is very basic research we are talking about here and may take decades to implement," says Leitenstorfer.

The next step is to experiment with a variety of different setups using the same principle. This approach might even offer insights into quantum computing, the researchers say, although there's a lot more work to get through yet - we can't wait to see what they'll achieve next.

PG&E power restoration continues across Butte and Yuba counties after PSPS shut-offs from high winds and dry weather, with crews patrolling overhead lines, repairing damage, and reopening community resource centers near Lake Berryessa.

Key Points

PG&E power restoration safely re-energizes lines after PSPS, using inspections and repairs to restore service.

✅ Crews patrolled 800 miles of overhead lines for hazards

✅ Repairs followed wind damage; gradual re-energization

✅ Resource centers offered water, outlets, air conditioning

Pacific Gas and Electric Co. field crews have begun restoring power to approximately 20,500 customers in Butte and Yuba counties after the utility shut off electricity to reduce wildfire risk because of gusty winds and dry weather conditions.

More than half of the affected customers had electricity again as of 1:47 p.m. Sunday, according to PG&E, and by 4 p.m. all of Yuba County power had been restored.

The utility also cut electricity for about 1,600 customers in parts of Napa, Solano and Yolo counties, primarily in the Lake Berryessa area, in a PSPS event separate from statewide grid conservation alerts that can trigger rolling blackouts. Power to those areas was switched off at 6:15 a.m. Saturday but was restored by the evening.

As the danger subsided Sunday, utility workers, as part of PG&E's local response planning for winter storms, worked throughout Butte and Yuba counties to re-energize power lines. The shut-offs affected areas including eastern Chico, Oroville and fire-ravaged Paradise.

Technicians checked lines for damage or fire hazards, like vegetation that could interfere with live wires, Pasion said, as part of broader pandemic grid preparedness that informed utility protocols.

PG&E “patrolled approximately 800 miles of overhead power lines,” the company said in a statement. “Crews found instances of damage to de-energized equipment caused by the extreme weather event and are making necessary repairs.”

While the shut-offs inconvenienced businesses and homeowners, they also highlighted energy inequality across impacted neighborhoods, and some called 911 with emergencies and confusion.

A half hour into the shut-off Saturday night, Butte County sheriff’s dispatchers received a call from a person requesting a welfare check on an individual whose care required electricity, according to department call logs. Two calls overnight from the Magalia area requested medical assistance because residents had oxygen concerns for medically sensitive spouses.

One woman requested an ambulance because her “husband was running out of oxygen,” according to the logs.

Around 4:11 a.m. Sunday, a resident of Hidden Valley Mobile Home Park in Oroville called about a tree falling into a trailer, causing a power line to fall, but noted that the electricity was off.

In a comparable storm-related outage, Sudbury Hydro crews worked to reconnect service after severe weather in Ontario.

And there were multiple calls asking for information about the shut-off, including one caller around midnight who was “demanding PG&E turn his power back on.”

The calls led the Butte County Sheriff’s Office to tweet a reminder Sunday afternoon that 911 is reserved for emergencies and requests for information about the power shutdown should be done through PG&E.

The utility opened a community resource center at Harrison Stadium in Oroville (Butte County) on Sunday morning to provide restrooms, bottled water, power outlets and air conditioning to residents. About 40 people showed up at the center in the first few hours, officials said.

“It’s a small but steady stream,” Pasion said.

Power was being restored to parts of Oroville as of 11 a.m. Sunday.

PG&E officials said it could take up to 48 hours for power to be restored in some areas.

For perspective, during severe storms in Ontario, Hydro One crews restored power to more than 277,000 customers within days.

Siemens Gamesa SG 14-222 DD advances offshore wind with a 14 MW direct-drive turbine, 108 m blades, a 222 m rotor, optional 15 MW boost, powering about 18,000 homes; prototype 2021, commercial launch 2024.

Key Points

A 14 MW offshore wind turbine with 108 m blades and a 222 m rotor, upgradable to 15 MW, targeting commercial use in 2024.

✅ 14 MW direct-drive, upgradable to 15 MW

✅ 108 m blades, 222 m rotor diameter

✅ Powers about 18,000 European homes annually

Siemens Gamesa Renewable Energy (SGRE) has released details of a 14-megawatt (MW) offshore wind turbine, as offshore green hydrogen production gains attention, in the latest example of how technology in the sector is increasing in scale.

With 108-meter-long blades and a rotor diameter of 222 meters, the dimensions of the SG 14-222 DD turbine are significant.

In a statement Tuesday, SGRE said that one turbine would be able to power roughly 18,000 average European households annually, while its capacity can also be boosted to 15 MW if needed. A prototype of the turbine is set to be ready by 2021, and it’s expected to be commercially available in 2024, as forecasts suggest a $1 trillion business this decade.

As technology has developed over the last few years, the size of wind turbines has increased, and renewables are set to shatter records globally.

Last December, for example, Dutch utility Eneco started to purchase power produced by the prototype of GE Renewable Energy’s Haliade-X 12 MW wind turbine. That turbine has a capacity of 12 MW, a height of 260 meters and a blade length of 107 meters.

The announcement of Siemens Gamesa’s new turbine plans comes against the backdrop of the coronavirus pandemic, which is impacting renewable energy companies around the world, even as wind power sees growth despite Covid-19 in many markets.

Earlier this month, the European company said Covid-19 had a “direct negative impact” of 56 million euros ($61 million) on its profitability between January and March, amid factory closures in Spain and supply chain disruptions. This, it added, was equivalent to 2.5% of revenues during the quarter.

The pandemic has, in some parts of the world, altered the sources used to power society. At the end of April, for instance, it was announced that a new record had been set for coal-free electricity generation in Great Britain, where UK offshore wind growth has accelerated, with a combination of factors — including coronavirus-related lockdown measures — playing a role.

On Tuesday, the CEO of another major wind turbine manufacturer, Danish firm Vestas, sought to emphasize the importance of renewable energy in the years and months ahead, and the lessons the U.S. can learn from the U.K. on wind deployment.

“I think we have actually, throughout this crisis, also shown to all society that renewables can be trusted,” Henrik Andersen said during an interview on CNBC’s Street Signs.

“But we both know ... that that transformation of energy sources is not going to happen overnight, it’s not going to happen from a quarter to a quarter, it’s going to happen by consistently planning year in, year out.”

Ontario has initiated the construction of Canada's first small modular nuclear reactor (SMR), supported by OPG's SMR commitment to deployment, marking a significant milestone in the province's energy strategy. This development positions Ontario at the forefront of next-generation nuclear technology within the G7 nations.

The project, known as the Darlington New Nuclear Project, is being led by Ontario Power Generation (OPG) in collaboration with GE Vernova and Hitachi Nuclear Energy, and through its OPG-TVA partnership on new nuclear technology development. The chosen design is the BWRX-300, a 300-megawatt boiling water reactor that is approximately one-tenth the size and complexity of traditional nuclear reactors. The first unit is expected to be operational by 2029, with plans for additional units to follow.

Each BWRX-300 reactor is projected to supply electricity to about 300,000 homes, contributing to Ontario's efforts, which include the decision to refurbish Pickering B for additional baseload capacity, to meet the anticipated 75% increase in electricity demand by 2050. The compact design of the SMR allows for easier integration into existing infrastructure, reducing the need for extensive new transmission lines.

The economic impact of the project is substantial. The construction of four such reactors is expected to create up to 18,000 jobs and contribute approximately $38.5 billion CAD to the Canadian economy, reflecting the economic benefits of nuclear projects over 65 years. The modular nature of SMRs also allows for scalability, with each additional unit potentially reducing costs through economies of scale.

Safety is a paramount consideration in the design of the BWRX-300. The reactor employs passive safety features, meaning it can safely shut down without the need for external power or operator intervention. This design enhances the reactor's resilience to potential emergencies, aligning with stringent regulatory standards.

Ontario's commitment to nuclear energy is further demonstrated by its plans for four SMRs at the Darlington site. This initiative reflects a broader strategy to diversify the province's energy mix, incorporating clean and reliable power sources to complement renewable energy efforts.

While the development of SMRs in Ontario is a significant step forward, it also aligns with the Canadian nuclear initiative positioning Canada as a leader in the global nuclear energy landscape. The successful implementation of the BWRX-300 could serve as a model for other nations exploring advanced nuclear technologies.

Ontario's groundbreaking work on small modular nuclear reactors represents a forward-thinking approach to energy generation. By embracing innovative technologies, the province is not only addressing future energy demands but also, through the Pickering NGS life extension, contributing to the global transition towards sustainable and secure energy solutions.
