Bullfrog Power, together with Enbridge Gas Distribution, EnerWorks, and the Government of Canada announced the launch of a new Solar Water Heating Program.

Solar water heating allows homeowners to reduce their energy costs and environmental impact by harnessing the sun's energy through the installation of their own solar water heating systems.

At the time of purchase, qualifying homeowners will receive a substantial savings on the purchase and installation of their own solar water heating systems. These savings are made possible through the Government of Canada's ecoENERGY for Renewable Heat program and volume discounts from EnerWorks. Interested homeowners may also qualify for further rebates and credits through the ecoENERGY Retrofit-Homes program, provincial rebates and the new Home Renovation Tax Credit.

This limited-time offer will give homeowners in the Enbridge Gas Distribution franchise area the opportunity to save up to 50 per cent on their own solar water heating systems. They may also reduce their ongoing water heating energy costs by up to 60 per cent and financing for the installation is available from as little as $56 dollars a month.

"By investing $1.4 million in this project, the Government of Canada will help generate new economic activity in Ontario, while reducing energy costs and harmful emissions," said the Honourable Lisa Raitt, Minister of Natural Resources. "This is another example of how we are investing in projects that will stimulate the domestic clean energy industry, create jobs for Canadians and help boost our economy."

Bullfrog Power, Canada's leading 100 per cent green electricity provider, is pleased to participate in a program that helps Ontarians conserve energy and save money.

"New technology, active energy conservation activities and green power are all effective ways that homeowners can reduce their environmental impact," said Tom Heintzman, President, Bullfrog Power. "Through this new Solar Water Heating Program, we are happy to provide another option that makes it easy for Ontarians to support renewable energy."

"Enbridge Gas Distribution is a leader in energy efficiency and continues to advance sustainable energy solutions that will lead us towards a clean energy economy," said Arunas Pleckaitis, Vice President, Enbridge Gas Distribution.

Together with Enbridge's market delivery capabilities, we are able to provide an integrated high-value solution that customers will find attractive."

The program uses solar water heating systems manufactured in Ontario by EnerWorks. The systems are Canada's first solar water heaters to receive all-season CSA certification.

Local, certified contractors will professionally install each unit purchased. The integrated system is composed of three parts-solar panels, an energy pack and a solar storage tank-that work together to meet a household's primary demand for hot water, while the existing water heater provides a secondary heating source. Solar water heating does not affect the quality or the availability of the hot water. The systems provide a clean, cost-effective way to reduce water-heating costs, while also significantly reducing greenhouse gas emissions and air pollution.

"This solar water heating program represents a fabulous opportunity for homeowners to realize the economic and environmental benefits of heating their water with the renewable power of the sun, while taking advantage of significant additional incentives and discounts," says Dr. Phil Whiting, EnerWorks President and CEO. "EnerWorks is very pleased to be participating in this program and to support the environmental efforts of companies such as Bullfrog and Enbridge Gas Distribution."

Installation of a solar water heater is straightforward and completed by a trained and certified installer. Homeowners can arrange for a free site inspection to determine if the system is right for their home. EnerWorks-certified contractors will professionally install the systems quickly and efficiently, and help book the ecoENERGY Home Retrofit audits for further rebates and incentives.

Project examines potential for Europe's power grid to increase HVDC Technology

HVDC-WISE Project accelerates HVDC technology integration across the European transmission system, delivering a planning toolkit to boost grid reliability, resilience, and interconnectors for renewables and offshore wind amid climate, cyber, and physical threats.

 

Key Points

EU-funded project delivering tools to integrate HVDC into Europe's grid, improving reliability, resilience, and security.

✅ EU Horizon Europe-backed consortium of 14 partners

✅ Toolkit to assess extreme events and grid operability

✅ Supports interconnectors, offshore wind, and renewables

 

A partnership of 14 leading European energy industry companies, research organizations and universities has launched a new project to identify opportunities to increase integration of HVDC technology into the European transmission system, echoing calls to invest in smarter electricity infrastructure from abroad.

The HVDC-WISE project, in which the University of Strathclyde is the UK’s only academic partner, is supported by the European Union’s Horizon Europe programme.

The project’s goal is to develop a toolkit for grid developers to evaluate the grid’s performance under extreme conditions and to plan systems, leveraging a digital grid approach that supports coordination to realise the full range of potential benefits from deep integration of HVDC technology into the European transmission system.

The project is focused on enhancing electric grid reliability and resilience while navigating the energy transition. Building and maintaining network infrastructure to move power across Europe is an urgent and complex task, and reducing losses with superconducting cables can play a role, particularly with the continuing growth of wind and solar generation. At the same time, threats to the integrity of the power system are on the rise from multiple sources, including climate, cyber, and physical hazards.

 

Mutual support

At a time of increasing worries about energy security and as Europe’s electricity systems decarbonise, connections between them to provide mutual support and routes to market for energy from renewables, a dynamic also highlighted in discussions of the western Canadian electricity grid in North America, become ever more important.

In modern power systems, this means making use of High Voltage Direct Current (HVDC) technology.

The earliest forms of technology have been around since the 1960s, but the impact of increasing reliance on HVDC and its ability to enhance a power system’s operability and resilience are not yet fully understood.

Professor Keith Bell, Scottish Power Professor of Future Power Systems at the University of Strathclyde, said:

As an island, HVDC is the only practical way for us to build connections to other countries’ electricity systems. We’re also making use of it within our system, with one existing and more planned Scotland-England subsea link projects connecting one part of Britain to another.

“These links allow us to maximise our use of wind energy. New links to other countries will also help us when it’s not windy and, together with assets like the 2GW substation now in service, to recover from any major disturbances that might occur.

“The system is always vulnerable to weather and things like lightning strikes or short circuits caused by high winds. As dependency on electricity increases, insights from electricity prediction specialists can inform planning as we enhance the resilience of the system.”

Dr Agusti Egea-Alvarez, Senior Lecturer at Strathclyde, said: “HVDC systems are becoming the backbone of the British and European electric power network, either interconnecting countries, or connecting offshore wind farms.

“The tools, procedures and guides that will be developed during HVDC-WISE will define the security, resilience and reliability standards of the electric network for the upcoming decades in Europe.”

Other project participants include Scottish Hydro Electric Transmission, the Supergrid Institute, the Electric Power Research Institute (EPRI) Europe, Tennet TSO, Universidad Pontificia Comillas, TU Delft, Tractebel Impact and the University of Cyprus.

 

Climate change

Eamonn Lannoye, Managing Director of EPRI Europe, said: “The European electricity grid is remarkably reliable by any standard. But as the climate changes and the grid becomes exposed to more extreme conditions, energy interdependence between regions intensifies and threats from external actors emerge. The new grid needs to be robust to those challenges.”

Juan Carlos Gonzalez, a senior researcher with the SuperGrid Institute which leads the project said: “The HVDC-WISE project is intended to provide planners with the tools and know-how to understand how grid development options perform in the context of changing threats and to ensure reliability.”

HVDC-WISE is supported by the European Union’s Horizon Europe programme under agreement 101075424 and by the UK Research and Innovation Horizon Europe Guarantee scheme.

Ontario Drops Starlink Deal, Eyes Energy Independence

Ontario Starlink Contract Cancellation underscores rising tariffs, trade tensions, and retaliation, as SpaceX's Elon Musk loses a rural broadband deal; Ontario pivots to procurement bans, energy resilience, and nuclear power to boost grid independence.

 

Key Points

Ontario ended a C$100M Starlink deal over U.S. tariffs, prompting a shift to rural broadband alternatives.

✅ Triggered by U.S. tariffs; Ontario adopts retaliatory procurement bans.

✅ Ends plan to connect 15,000 rural homes and businesses with broadband.

✅ Signals push for energy resilience, nuclear power, and grid independence.

 

In a decisive move, Ontario Premier Doug Ford announced the cancellation of a C$100 million contract with Elon Musk's Starlink, a subsidiary of SpaceX, in direct response to U.S. President Donald Trump's imposition of tariffs on Canadian imports. This action underscores the escalating trade tensions between Canada and the United States, a theme highlighted during Ford's Washington meeting on energy tariffs earlier this month, and highlights Ontario's efforts to safeguard its economic interests.

The now-terminated agreement, established in November, aimed to provide high-speed internet access to 15,000 homes and businesses in Ontario's remote areas. Premier Ford's decision to "rip up" the contract signifies a broader strategy to distance the province from U.S.-based companies amid the current trade dispute. He emphasized, "Ontario won't do business with people hell-bent on destroying our economy."

This move is part of a series of retaliatory measures by Canadian provinces, including Ford's threat to cut electricity exports to the U.S., following President Trump's announcement of a 25% tariff on nearly all Canadian imports, excluding oil, which faces a 10% surcharge. These tariffs, set to take effect imminently, have prompted concerns about potential economic downturns in Canada. In response, Prime Minister Justin Trudeau declared that Canada would impose 25% tariffs on C$155 billion worth of U.S. goods, aiming to exert pressure on the U.S. administration to reconsider its stance.

Premier Ford's actions reflect a broader sentiment of economic nationalism, as he also announced a ban on American companies from provincial contracts until the U.S. tariffs are lifted. He highlighted that Ontario's government and its agencies allocate $30 billion annually on procurement, and reiterated his earlier vow to fire the Hydro One CEO and board as part of broader reforms aimed at efficiency.

The cancellation of the Starlink contract raises concerns about the future of internet connectivity in Ontario's rural regions. The original deal with Starlink was seen as a significant step toward bridging the digital divide, offering high-speed internet to underserved communities. With the contract's termination, the province faces the challenge of identifying alternative solutions to fulfill this critical need.

Beyond the immediate implications of the Starlink contract cancellation, Ontario is confronting broader challenges in ensuring the resilience and independence of its energy infrastructure. The province's reliance on external entities for critical services, such as internet connectivity and energy, has come under scrutiny, as Canada's electricity exports are at risk amid ongoing trade tensions and policy uncertainty.

Premier Ford has expressed a commitment to expanding Ontario's capacity to generate nuclear power as a means to bolster energy self-sufficiency. While this strategy aims to reduce dependence on external energy sources, it presents its own set of challenges that critics argue require cleaning up Ontario's hydro mess before new commitments proceed. Developing nuclear infrastructure requires substantial investment, rigorous safety protocols, and long-term planning. Moreover, the integration of nuclear power into the province's energy mix necessitates careful consideration of environmental impacts and public acceptance.

The concept of "Trump-proofing" Ontario's electricity grid involves creating a robust and self-reliant energy system capable of withstanding external political and economic pressures. Achieving this goal entails diversifying energy sources, including building on Ontario's electricity deal with Quebec to strengthen interties, investing in renewable energy technologies, and enhancing grid infrastructure to ensure stability and resilience.

However, the path to energy independence is fraught with complexities. Balancing the immediate need for reliable energy with long-term sustainability goals requires nuanced policy decisions, including Ontario's Supreme Court challenge to the global adjustment fee and related regulatory reviews to clarify cost impacts. Additionally, fostering collaboration between government entities, private sector stakeholders, and the public is essential to navigate the multifaceted challenges associated with overhauling the province's energy framework.

Ontario's recent actions, including the cancellation of the Starlink contract, underscore the province's proactive stance in safeguarding its economic and infrastructural interests amid evolving geopolitical dynamics. While such measures reflect a commitment to self-reliance, they also highlight the intricate challenges inherent in reducing dependence on external entities. As Ontario charts its course toward a more autonomous future, strategic planning, investment in sustainable technologies, and collaborative policymaking will be pivotal in achieving long-term resilience and prosperity.

Washington State Ferries' Hybrid-Electric Upgrade

Washington State Hybrid-Electric Ferries advance green maritime transit with battery-diesel propulsion, lower emissions, and fleet modernization, integrating charging infrastructure and reliable operations across WSF routes to meet climate goals and reduce fuel consumption.

 

Key Points

New WSF vessels using diesel-battery propulsion to cut emissions, improve efficiency, and sustain reliable ferry service.

✅ Hybrid diesel-battery propulsion reduces fuel use and CO2

✅ Larger vessels with efficient batteries and charging upgrades

✅ Compatible with WSF docks, maintenance, and safety standards

 

Washington State is embarking on an ambitious update to its ferry fleet, introducing hybrid-electric boats that represent a significant leap toward greener and more sustainable transportation. The state’s updated plans reflect a commitment to reducing carbon emissions and enhancing environmental stewardship while maintaining the efficiency and reliability of its vital ferry services.

The Washington State Ferries (WSF) system, one of the largest in the world, has long been a critical component of the state’s transportation network, linking various islands and coastal communities with the mainland. Traditionally powered by diesel engines, the ferries are responsible for significant greenhouse gas emissions. In response to growing environmental concerns and legislative pressure, WSF is now turning to hybrid-electric technology similar to battery-electric high-speed ferries seen elsewhere to modernize its fleet and reduce its carbon footprint.

The updated plans for the hybrid-electric boats build on earlier efforts to introduce cleaner technologies into the ferry system. The new designs incorporate advanced hybrid-electric propulsion systems that combine traditional diesel engines with electric batteries. This hybrid approach allows the ferries to operate on electric power during certain segments of their routes, reducing reliance on diesel fuel and cutting emissions as electric ships on the B.C. coast have demonstrated during similar operations.

One of the key features of the updated plans is the inclusion of larger and more capable hybrid-electric ferries, echoing BC Ferries hybrid ships now entering service in the region. These vessels are designed to handle the demanding operational requirements of the Washington State Ferries system while significantly reducing environmental impact. The new boats will be equipped with state-of-the-art battery systems that can store and utilize electric power more efficiently, leading to improved fuel economy and lower overall emissions.

The transition to hybrid-electric ferries is driven by both environmental and economic considerations. On the environmental side, the move aligns with Washington State’s broader goals to combat climate change and reduce greenhouse gas emissions, including programs like electric vehicle rebate program that encourage cleaner travel across the state. The state has set ambitious targets for reducing carbon emissions across various sectors, and upgrading the ferry fleet is a crucial component of achieving these goals.

From an economic perspective, hybrid-electric ferries offer the potential for long-term cost savings. Although the initial investment in new technology can be substantial, with financing models like CIB support for B.C. electric ferries helping spur adoption and reduce barriers for agencies, the reduced fuel consumption and lower maintenance costs associated with hybrid-electric systems are expected to lead to significant savings over the lifespan of the vessels. Additionally, the introduction of greener technology aligns with public expectations for more sustainable transportation options.

The updated plans also emphasize the importance of integrating hybrid-electric technology with existing infrastructure. Washington State Ferries is working to ensure that the new vessels are compatible with current docking facilities and maintenance practices. This involves updating docking systems, as seen with Kootenay Lake electric-ready ferry preparations, to accommodate the specific needs of hybrid-electric ferries and training personnel to handle the new technology.

Public response to the hybrid-electric ferry initiative has been largely positive, with many residents and environmental advocates expressing support for the move towards greener transportation. The new boats are seen as a tangible step toward reducing the environmental impact of one of the state’s most iconic transportation services. The project also highlights Washington State’s commitment to innovation and leadership in sustainable transportation, alongside global examples like Berlin's electric flying ferry that push the envelope in maritime transit.

However, the transition to hybrid-electric ferries is not without its challenges. Implementing new technology requires careful planning and coordination, including addressing potential technical issues and ensuring that the vessels meet all safety and operational standards. Additionally, there may be logistical challenges associated with integrating the new ferries into the existing fleet and managing the transition without disrupting service.

Despite these challenges, the updated plans for hybrid-electric boats represent a significant advancement in Washington State’s efforts to modernize its transportation system. The initiative reflects a growing trend among transportation agencies to embrace sustainable technologies and address the environmental impact of traditional transportation methods.

In summary, Washington State’s updated plans for hybrid-electric ferries mark a crucial step towards a more sustainable and environmentally friendly transportation network. By incorporating advanced hybrid-electric technology, the state aims to reduce carbon emissions, improve fuel efficiency, and align with its broader climate goals. While challenges remain, the initiative demonstrates a commitment to innovation and underscores the importance of transitioning to greener technologies in the quest for a more sustainable future.

27,000 Plus More Clean Energy Jobs Lost in May

U.S. Clean Energy Job Losses highlight COVID-19 impacts on renewable energy, solar, wind, and energy efficiency, with PPP fatigue, unemployment, and calls for Congressional stimulus, per Department of Labor data analyzed by E2.

 

Key Points

Pandemic-driven layoffs across renewable, solar, wind, and efficiency sectors, risking recovery without federal aid.

✅ Over 620,500 clean energy jobs lost in three months

✅ Energy efficiency, solar, and wind hit hardest nationwide

✅ Industry urges Congress for stimulus, tax credit relief

 

As Congress this week begins debating economic stimulus support for the energy industry, a new analysis of unemployment data shows the biggest part of America's energy economy - clean energy - lost another 27,000 jobs in May, bringing the total number of clean energy workers who have lost their jobs in the past three months to more than 620,500.

While May saw an improvement in new unemployment claims over March and April, the findings represent the sector's third straight month of significant job losses across solar, wind, energy efficiency, clean vehicles and other industries. With coronavirus cases once again rising in many states and companies beginning to run out of the Payroll Protection Program (PPP) funding that has helped small businesses keep workers employed, and as households confront pandemic power shut-offs that heighten energy insecurity, the report increases concerns the sector will be unable to resume its economy-leading jobs growth in the short- or long-term without a significant policy response.

Given the size and scope of the clean energy industry, such a sustained loss would cast a pall on the nation's overall economic recovery, as shifting electricity demand during COVID-19 complicates forecasts, according to the analysis of the Department of Labor's May unemployment data from E2 (Environmental Entrepreneurs), E4TheFuture and the American Council on Renewable Energy (ACORE).

Prior to COVID-19, clean energy - including energy efficiency, solar and wind generation, clean vehicles and related sectors - was among the U.S. economy's biggest and fastest-growing employment sectors, growing 10.4% since 2015 to nearly 3.4 million jobs at the end of 2019. That made clean energy by far the biggest employer of workers in all energy occupations, employing nearly three times as many people as the fossil fuel industry. For comparison, coal mining employs about 47,000 workers, even as clean energy projects in coal communities aim to revitalize local economies.

The latest monthly analysis for the groups by BW Research Partnership runs contrary to recent Bureau of Labor Statistics (BLS) reports, which indicated that a more robust economic rebound was underway, even as high fuel prices haven't spurred a green shift in adoption, while also acknowledging misclassifications and serious reporting difficulties in its own data.

Bob Keefe, Executive Director at E2, said:

"May's almost 30,000 clean energy jobs loss is sadly an improvement in the rate of jobs shed but make no mistake: There remains huge uncertainty and volatility ahead. It will be very tough for clean energy to make up these continuing job losses without support from Congress. Lawmakers must act now. If they do, we can get hundreds of thousands of these workers back on the job today and build a better, cleaner, more equitable economy for tomorrow. And who doesn't want that?"

Pat Stanton, Policy Director at E4TheFuture, said:

"Most of the time, energy efficiency workers need to go inside homes, businesses and other buildings to get the job done. Since they couldn't do that during COVID lockdowns, they couldn't work. Now states are opening up. But utilities, contractors and building owners need to protect employees and occupants from possible exposure to the virus and need more clarity about potential liabilities."

Gregory Wetstone, President and CEO of ACORE, said:

"In May, we saw thousands of additional renewable energy workers join the ranks of the unemployed, further underscoring the damage COVID-19 is inflicting on our workforce. Since the pandemic began, nearly 100,000 renewable energy workers have lost their jobs. We need help from Congress to get American clean energy workers back to work. With commonsense measures like temporary refundability and a delay in the phasedown of renewable energy tax credits, Congress can help restore these good-paying jobs so the renewable sector can continue to provide the affordable, pollution-free power American consumers and businesses want and deserve."

Phil Jordan, Vice President and Principal at BW Research Partnership, said:

"We understand the challenges and limitations of data collection for BLS in the middle of a global pandemic. But any suggestion that a strong employment rebound is underway in the United States simply is not reflected in the clean energy sector right now. And with PPP expiring, that only increases uncertainty in the months ahead."

The report comes as both the Senate Committee on Energy and Natural Resources and the House Energy and Commerce Committee are considering clean energy stimulus to restart the U.S. economy, and amid assessments of mixed results from the climate law shaping expectations, and as lawmakers in both the House and Senate are increasing calls for supporting clean energy workers and businesses, including this bicameral letter signed by 57 members of Congress and another signed today by 180 House members.

Industries Hit Hardest

According to the analysis, energy efficiency lost more jobs than any other clean energy sector for the third consecutive month in May, shedding about 18,900 jobs. These workers include electricians, HVAC technicians who work with high-efficiency systems, and manufacturing employees who make Energy Star appliances, LED lighting systems and efficient building materials.

Renewable energy, including solar and wind, lost nearly 4,300 jobs in May.

Clean grid and storage and clean vehicles manufacturing -- including grid modernization, energy storage, car charging and electric and plug-in hybrid vehicle manufacturing -- lost a combined 3,200 jobs in May, as energy crisis impacts electricity, gas, and EVs in several ways.

The clean fuels sector lost more than 650 jobs in May.

States and Localities Hit Across Country

California continues to be the hardest hit state in terms of total job losses, losing 4,313 jobs in May and more than 109,700 since the COVID-19 crisis began. Florida was the second hardest hit state in May, losing an additional 2,563 clean energy jobs, while Georgia, Texas, Washington, and Michigan all suffered more than 1,000 job losses across the sector. An additional 12 states saw at least 500 clean energy unemployment filings, and reports like Pennsylvania's clean energy jobs analysis provide added context, according to the latest analysis.

Southern California Edison Faces Lawsuits Over Role in California Wildfires

SCE Wildfire Lawsuits allege utility equipment and power lines sparked deadly Los Angeles blazes; investigations, inverse condemnation, and stricter utility regulations focus on liability, vegetation management, and wildfire safety amid Santa Ana winds.

 

Key Points

Residents sue SCE, alleging power lines ignited LA wildfires; seeking compensation under inverse condemnation.

✅ Videos cited show sparking lines near alleged ignition points.

✅ SCE denies wrongdoing; probes and inspections ongoing.

✅ Inverse condemnation may apply regardless of negligence.

 

In the aftermath of devastating wildfires in Los Angeles, residents have initiated legal action, similar to other mega-fire lawsuits underway in California, against Southern California Edison (SCE), alleging that the utility's equipment was responsible for sparking one of the most destructive fires. The fires have resulted in significant loss of life and property, prompting investigations into the causes and accountability of the involved parties.

The Fires and Their Impact

In early January 2025, Los Angeles experienced severe wildfires that ravaged neighborhoods, leading to the loss of at least 29 lives and the destruction of approximately 155 square kilometers of land. Areas such as Pacific Palisades and Altadena were among the hardest hit. The fires were exacerbated by arid conditions and strong Santa Ana winds, which contributed to their rapid spread and intensity.

Allegations Against Southern California Edison

Residents have filed lawsuits against SCE, asserting that the utility's equipment, particularly power lines, ignited the fires. Some plaintiffs have presented videos they claim show sparking power lines in the vicinity of the fire's origin. These legal actions seek to hold SCE accountable for the damages incurred, including property loss, personal injury, and emotional distress.

SCE's Response and Legal Context

Southern California Edison has denied any wrongdoing, stating that it has not detected any anomalies in its equipment that could have led to the fires. The utility has pledged to cooperate fully with investigations to determine the causes of the fires. California's legal framework, particularly the doctrine of "inverse condemnation," allows property owners to seek compensation from utilities for damages caused by public services, even without proof of negligence. This legal principle has been central in previous cases involving utility companies and wildfire damages, and similar allegations have arisen in other jurisdictions, such as an alleged faulty transformer case, highlighting shared risks.

Historical Context and Precedents

This situation is not unprecedented. In 2018, Pacific Gas and Electric (PG&E) faced similar allegations when its equipment was implicated in the Camp Fire, the deadliest wildfire in California's history. PG&E's equipment was found to have ignited the fire, and the company later pleaded guilty in the Camp Fire, leading to extensive litigation and financial repercussions for the company, while its bankruptcy plan won support from wildfire victims during restructuring. The case highlighted the significant risks utilities face regarding wildfire safety and the importance of maintaining infrastructure to prevent such disasters.

Implications for California's Utility Regulations

The current lawsuits against SCE underscore the ongoing challenges California faces in balancing utility operations with wildfire prevention, as regulators face calls for action amid rising electricity bills. The state has implemented stricter regulations and oversight, and lawmakers have moved to crack down on utility spending to mitigate wildfire risks associated with utility infrastructure. Utilities are now required to invest in enhanced safety measures, including equipment inspections, vegetation management, and the implementation of advanced technologies to detect and prevent potential fire hazards. These regulatory changes aim to reduce the incidence of utility-related wildfires and protect communities from future disasters.

The legal actions against Southern California Edison reflect the complex interplay between utility operations, public safety, and environmental stewardship. As investigations continue, the outcomes of these lawsuits may influence future policies and practices concerning utility infrastructure and wildfire prevention in California. The state remains committed to enhancing safety measures to protect its residents and natural resources from the devastating effects of wildfires.

Physicists Just Achieved Conduction of Electricity at Close to The Speed of Light

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.
