Hydro-Québec puts global ambitions on hold as crisis weighs on demand

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.

EU-UK Coal Power Decline 2020 underscores Covid-19's impact on power generation, with renewables rising, carbon emissions falling, and electricity demand down, revealing resilient grids and accelerating the energy transition across European markets.

Key Points

Covid-19's impact on EU-UK power: coal down, renewables up, lower emissions intensity and reduced electricity demand.

✅ Coal generation down 25.5% EU-UK; 29% in March 10-April 10 period

✅ Renewables share up to 46%; grids remained stable and flexible

✅ Electricity demand fell 10%; emissions intensity dropped 19.5%

Coal based power generation has fallen by over a quarter (25.5%) across the European Union (EU) and United Kingdom (UK) in the first three months of 2020, compared to 2019, as a result of the response to Covid-19, with renewable energy reaching a 43% share, as wind and solar outpaced gas across the EU, according to new analysis by the technology group Wärtsilä.

The impact is even more stark in the last month, with coal generation collapsing by almost one third (29%) between March 10 and April 10 compared to the same period in 2019, making up only 12% of total EU and UK generation. By contrast, renewables delivered almost half (46%) of generation – an increase of 8% compared to 2019.

In total, demand for electricity across the continent is down by one tenth (10%), mirroring global demand declines of around 15%, due to measures taken to combat Covid-19, the biggest drop in demand since the Second World War. The result is an unprecedented fall in carbon emissions from the power sector, with emission intensity falling by 19.5% compared to the same March 10-April 10 period last year. The analysis comes from the Wärtsilä Energy Transition Lab, a new free-to-use data platform developed by Wärtsilä to help the industry, policy makers and the public understand the impact of Covid-19 on European electricity markets and analyse what this means for the future design and operation of its energy systems. The goal is to help accelerate the transition to 100% renewables.

Björn Ullbro, Vice President for Europe & Africa at Wärtsilä Energy Business, said: “The impact of the Covid-19 crisis on European energy systems is extraordinary. We are seeing levels of renewable electricity that some people believed would cause systems to collapse, yet they haven’t – in fact they are coping well. The question is, what does this mean for the future?”

“What we can see today is how our energy systems cope with much more renewable power – knowledge that will be invaluable, aligning with IAEA low-carbon insights, to accelerate the energy transition. We are making this new platform freely available to support the energy industry to adapt and use the momentum this tragic crisis has created to deliver a better, cleaner energy system, faster.”

The figures mark a dramatic shift in Europe’s energy mix – one that was not anticipated to occur until the end of the decade. The impact of the Covid-19 crisis has effectively accelerated the energy transition in the short-term, even as later lockdowns saw power demand hold firm in parts of Europe, providing a unique opportunity to see how energy systems function with far higher levels of renewables.

Ullbro added: “Electricity demand across Europe has fallen due to the lockdown measures applied by governments to stop the spread of the coronavirus. However, total renewable generation has remained at pre-crisis levels with low electricity prices, combined with renewables-friendly policy measures, crowding out gas and fossil fuel power generation, especially coal. This sets the scene for the next decade of the energy transition.”

These Europe-wide impacts are mirrored at a national level, for example:

• In the UK, renewables now have a 43% share of generation, following a stall in low-carbon progress in 2019 (up 10% on the same March 10-April 10 period in 2019) with coal power down 35% and gas down 24%.
• Germany has seen the share of renewables reach 60% (up 12%) and coal generation fall 44%, resulting in a fall in the carbon intensity of its electricity of over 30%.
• Spain currently has 49% renewables with coal power down by 41%.
• Italy has seen the steepest fall in demand, down 21% so far.

An industry first, the Wärtsilä Energy Transition Lab has been specifically developed as an open-data platform for the energy industry to understand the impact of Covid-19 and help accelerate the energy transition. The tool provides detailed data on electricity generation, demand and pricing for all 27 EU countries and the UK, combining Entso-E data in a single, easy to use platform. It will also allow users to model how systems could operate in future with higher renewables, as global power demand surpasses pre-pandemic levels, helping pinpoint problem areas and highlight where to focus policy and investment.

Enbridge Alberta CCS Project targets carbon capture and storage in Alberta, capturing emissions from industrial emitters to advance net-zero goals, leveraging carbon pricing, regulatory support, and a hub model despite a key partner's exit.

Key Points

A proposed Alberta carbon capture hub by Enbridge to store industrial emissions and support net-zero targets.

✅ Seeks emitters across power, oil and gas, and heavy industry

✅ Backed by carbon pricing, regulation, and net-zero mandates

✅ Faces high capex, storage risk, and anchor-tenant uncertainty

Enbridge Inc., a Canadian energy giant, is digging its heels in on its proposed carbon capture and storage (CCS) project in Alberta. This comes despite the recent withdrawal of Capital Power, a major potential emitter that was expected to utilize the CCS technology. Enbridge maintains the project remains viable, but questions linger about its future viability without a cornerstone anchor.

The CCS project, envisioned as a major carbon capture hub in Alberta, aimed to capture emissions from industrial facilities and permanently store them underground. This technology has the potential to play a significant role in reducing greenhouse gas emissions and mitigating the effects of climate change, alongside grid solutions like bridging the Alberta-B.C. electricity gap that can complement decarbonization efforts.

Capital Power's decision to shelve its $2.4 billion Genesee Generating Station project, which was designed to integrate with the CCS hub, threw a wrench into Enbridge's plans. The Genesee project was expected to be a key source of emissions for capture and storage, and its status is being weighed as Ottawa advances the federal coal plan to phase out unabated coal.

Enbridge, however, remains optimistic. The company cites ongoing discussions with other potential emitters interested in utilizing the CCS technology, amid new funding signals such as the U.S. DOE's $110M for CCUS that highlight momentum. They believe the project holds significant value despite Capital Power's departure.

"We are confident in the long-term viability of the project and continue to actively engage with potential customers," said Enbridge spokesperson Rachel Giroux. "Carbon capture and storage is a critical technology for achieving net-zero emissions, and we believe there is a strong business case for our CCS project."

Enbridge's confidence hinges on several factors. Firstly, they believe there is a growing appetite for CCS technology amongst industrial facilities facing increasing pressure to reduce their carbon footprint. Regulations and carbon pricing mechanisms, including new U.S. EPA power plant rules that test CCS readiness, could further incentivize companies to adopt CCS solutions.

Secondly, Enbridge highlights the potential for capturing emissions from not just power plants but also from other industrial sectors like oil and gas production and clean hydrogen projects in Canada, where reforming processes can generate CO2. This broader application could significantly increase the captured carbon volume and strengthen the project's economic viability.

However, skepticism remains. Critics point to the high upfront costs associated with CCS development and the nascent stage of the technology. They argue that without a guaranteed stream of captured emissions, the project might not be financially sound. Additionally, the long-term safety and effectiveness of large-scale carbon storage solutions remain under scrutiny.

The success of Enbridge's CCS project hinges on attracting new emitters. Replacing Capital Power's contribution will be a significant challenge. Enbridge will need to demonstrate the project's economic viability and navigate the complex regulatory landscape surrounding CCS technology.

The Alberta government's position on CCS is crucial. While the government has expressed support for the technology, the level of financial and regulatory incentives offered will significantly impact investor confidence, especially as the IEA net-zero outlook underscores Canada's need for much more electricity. A clear and stable policy framework will be essential for attracting emitters to the project.

The future of Enbridge's CCS project remains uncertain. Capital Power's withdrawal is a setback, but Enbridge's continued commitment suggests they believe the technology holds promise. Whether they can find enough emitters to justify the project's development will be a critical test. The outcome will have significant implications for the future of CCS technology in Alberta and Canada's broader efforts to achieve net-zero emissions, including Canada-Germany clean energy cooperation that seeks to scale low-carbon fuels.

FirstEnergy Nuclear Plant Closures threaten Ohio and Pennsylvania jobs, tax revenue, and grid stability, as Nuclear Matters and Brattle Group warn of higher carbon emissions and market pressures from PJM and cheap natural gas.

Key Points

Planned shutdowns of Davis-Besse, Perry, and Beaver Valley, with regional economic and carbon impacts.

✅ Over 3,000 direct jobs and local tax revenue at risk

✅ Emissions may rise until renewables scale, possibly into 2034

✅ Debate over subsidies, market design, and PJM capacity rules

A national nuclear lobby wants to remind people what's at stake for Ohio and Pennsylvania if FirstEnergy Solutions follows through with plans to shut down three nuclear plants over the next three years, including its Davis-Besse nuclear plant east of Toledo.

A report issued Monday by Nuclear Matters largely echoes concerns raised by FES, a subsidiary of FirstEnergy Corp., and other supporters of nuclear power about economic and environmental hardships and brownout risks that will likely result from the planned closures.

Along with Davis-Besse, Perry nuclear plant east of Cleveland and the twin-reactor Beaver Valley nuclear complex west of Pittsburgh are slated to close.

"If these plants close, the livelihoods of thousands of Ohio and Pennsylvania residents will disappear. The over 3,000 highly skilled individuals directly employed by these sites will leave to seek employment at other facilities still operating around the country," Lonnie Stephenson, International Brotherhood of Electrical Workers president, said in a statement distributed by Nuclear Matters. Mr. Stephenson also serves on the Nuclear Matters advocacy council.

This new report and others like it are part of an extensive campaign by nuclear energy advocates to court state and federal legislators one more time for tens of millions of dollars of financial support or at least legislation that better suits the nuclear industry. Critics allege such pleas amount to a request for massive government bailouts, arguing that deregulated electricity markets should not subsidize nuclear.

The latest report was prepared for Nuclear Matters by the Brattle Group, a firm that specializes in analyzing economic, finance, and regulatory issues for corporations, law firms, and governments.

"These announced retirements create a real urgency to learn what would happen if these plants are lost," Dean Murphy, the Brattle report's lead author, said.

More than 3,000 jobs would be lost, as would millions of dollars in tax revenue. It also could take as long as 2034 for the region's climate-altering carbon emissions to be brought back down to existing levels, based on current growth projections for solar- and wind-powered projects, and initiatives such as ending coal by 2032 by some utilities, Mr. Murphy said.

His group's report only takes into account nuclear plant operations, though. Many of those who oppose nuclear power have long pointed out that mining uranium for nuclear plant fuel generates substantial emissions, as does the process of producing steel cladding for fuel bundles and the enrichment-production of that fuel. Still, nuclear has ranked among the better performers in reports that have taken such a broader look at overall emissions.

FES has accused the regional grid operator, PJM Interconnection, of creating market conditions that favor natural gas and, thus, make it almost impossible for nuclear to compete throughout its 13-state region, a debate intensified by proposed electricity pricing changes at the federal level.

PJM has strongly denied those accusations, and has said it anticipates no shortfalls in energy distribution if those nuclear plants close prematurely, even as a recent FERC decision on grid policy drew industry criticism.

FES, citing massive losses, has filed for Chapter 11 bankruptcy. The target dates for closures of the FES properties are May 31, 2020 for Davis-Besse; May 31, 2021 for Perry and Beaver Valley Unit 1, and Oct. 31, 2021 for Beaver Valley Unit 2.

In addition to the three FES sites, the report includes information about the Three Mile Island Unit 1 plant near Harrisburg, Pa., which Chicago-based Exelon Generation Corp. has previously announced will be shut down in 2019. That plant and others are experiencing similar difficulties the FES plants face by competing in a market radically changed by record-low natural gas prices.

BC Hydro Peak Electricity Demand reached a record 10,902 megawatts during a cold snap, driven by home heating. Peak hours surged; load shifting and energy conservation can ease strain on the grid and lower bills.

Key Points

Record winter peak of 10,902 MW, set during a cold snap, largely from home heating demand at peak hours.

✅ All-time high load: 10,902 MW between 5 and 6 p.m., Dec. 27.

✅ Cold snap increased home heating demand during peak hours.

✅ Shift laundry and dishwashers off-peak; use programmable thermostats.

BC Hydro says the province set a new record for peak electricity demand on Monday as temperatures hit extreme lows, and Quebec shattered consumption records during similar cold weather.

Between 5 and 6 p.m. on Dec. 27, demand for electricity hit an all-time high of 10,902 megawatts, which is higher than the previous record of 10,577 megawatts set in 2020, and follows a record-breaking year in 2021 for the utility.

“The record represents a single moment in the hour when demand for electricity was the highest yesterday,” says Simi Heer, BC Hydro spokesperson, in a statement. “Most of the increase is likely due to additional home heating required during this cold snap.”

In addition to the peak demand record on Monday, BC Hydro has observed an overall increase in electricity demand since Friday, and has noted that cryptocurrency mining electricity use is an emerging load in the province as well. Monday’s hourly peak demand was 18 per cent higher than Friday’s, while Calgary's electricity use soared during a frigid February, underscoring how cold snaps strain regional grids.

“BC Hydro has enough supply options in place to meet increasing electricity demand,” adds Heer, and pointed to customer supports like a winter payment plan for households managing higher bills. “However, if British Columbians want to help ease some of the demand on the system during peak times, we encourage shifting activities like doing laundry or running dishwashers to earlier in the day or later in the evening.”

BC Hydro is also offering energy conservation tips for people looking to lower their electricity use and their electricity bills, noting that Earth Hour once saw electricity use rise in the province:

Manage your home heating actively by turning the heat down when no one his home or when everyone is sleeping. Consider installing a programmable thermostat to automatically adjust temperatures at different times based on your family's activities, and remember that in warmer months wasteful air conditioning can add $200 to summer energy bills. BC Hydro recommends the following temperatures:

16 degrees Celsius when sleeping or away from home
21 degrees Celsius when relaxing, watching TV
18 degrees Celsius when doing housework or cleaning

Biden Clean Energy Plan 2035 accelerates carbon-free electricity with renewables, nuclear, hydropower, and biomass, invests $2T in EVs, grid and energy efficiency, and tightens fuel economy standards beyond the Clean Power Plan.

Key Points

A $2T U.S. climate plan for carbon-free power by 2035, boosting renewables, nuclear, EVs, efficiency, and grid upgrades.

✅ Targets a zero-carbon electric grid nationwide by 2035

✅ Includes renewables, nuclear, hydropower, and biomass in standard

✅ Funds EVs, grid modernization, weatherization, and fuel economy rules

This month the Democratic presumptive presidential nominee, Joe Biden, outlined an ambitious plan, including Biden’s solar plan to expand clean energy, for tackling climate change that shows how far the party has shifted on the issue since it controlled the White House.

President Barack Obama’s Clean Power Plan had called for the electricity sector to cut its carbon pollution 32 percent by 2030, and did not lay out a trajectory for phasing out oil, coal or natural gas production.

This year, Democratic 2020 hopefuls such as Sen. Bernie Sanders (I-Vt.) went much further, suggesting the United States should derive all of its electricity from renewable sources by 2030, moving to 100% renewables as part of a $16.3 trillion plan to wean the nation away from fossil fuels. Many other congressional Democrats have embraced the Green New Deal — the nonbinding resolution calling for a carbon-free power sector by 2030 and more energy efficient buildings and vehicles, along with a massive investment in electric vehicles and high-speed rail.

Last year, 38 percent of U.S. electricity generated came from clean sources, according to a Washington Post analysis of data from the U.S. Energy Information Administration, and in April renewables hit a record 28% nationwide.

Biden’s new plan, which carries a price tag of $2 trillion, would eliminate carbon emissions from the electric sector by 2035, impose stricter gas mileage standards, fund investments to weatherize millions of homes and commercial buildings, and upgrade the nation’s transportation system. To reach its 2035 carbon-free electricity goal, the campaign includes wind, solar and several forms of energy, acknowledging why the grid isn’t yet 100% renewable while balancing reliability, that are not always counted in state renewable portfolio standards, such as nuclear, hydropower and biomass.

“A great appeal of the Biden proposal is that it is much closer to targeting carbon directly, which is the ultimate enemy, and plays fewer favorites with particular technologies,” said Michael Greenstone, who directs the University of Chicago’s Energy Policy Institute. “This will reduce the costs to consumers and give more carbon bang for the buck.”

But some environmentalists, such as Friends of the Earth President Erich Pica, question the idea of including more controversial carbon-free technologies. “There is no role for nuclear in a least-cost, low carbon world. Including these dinosaurs in a clean energy standard is going to incentivize industry efforts to keep aging, dangerous facilities online,” Pica said in an email.

Hydropower, which relies on a system of moving water that constantly recharges, is defined as renewable by the Environmental Protection Agency. Biomass is often considered as carbon neutral because even though it releases carbon dioxide when it is burned, the plants capture nearly the same amount of CO2 while growing.

Both forms of energy have come under fire for their environmental impacts, however. Damming streams and rivers can destroy fish habitat and make it more difficult for them to spawn, and it also seems unlikely that hydropower will expand its current 6 percent share of the nation’s electrical grid.

Many experts argue that classifying biomass energy as carbon neutral provides an incentive to cut down trees that would otherwise remain standing and sequester carbon. “If burning this wood were good for the climate, then we should not recycle paper, we should burn it,” noted Tim Searchinger, a research scholar at the Princeton School of Public and International Affairs.

Illinois lead the nation in the amount of electricity generated from nuclear power

More than half of the country — 30 states, Washington, and three territories — have adopted a renewable portfolio standard (RPS), according to the National Conference of State Legislatures, and seven states and one territory have set renewable energy goals. While 14 states, along with the District, Puerto Rico and the Virgin Islands, have established requirements of 50 percent or more carbon-free electricity, nearly as many have set theirs at 15 percent or less.

Maine Gov. Janet Mills (D), who has called for 100% renewable electricity in the state, has pushed clean electricity aggressively since taking office in 2019, lifting a wind energy moratorium imposed by her predecessor and signing bills aimed at expanding the state’s carbon-free energy sources. Biomass accounts for a quarter of the state’s electricity, more than any other state.

New York has one of the country’s most ambitious climate targets, which it scaled up last year. It aims to obtain 70 percent of its power from renewable sources within a decade, a period when renewables surpassed coal in U.S. generation, and eliminate carbon altogether by 2040, even as the state is in the process of shutting down a major nuclear plant near New York City, Indian Point, which is slated to cease operating on April 30, 2021.

... while other states are weakening theirs

Last year, Ohio weakened its renewable energy standard from a target of 12.5 percent in 2027 to 8.5 percent by 2026, even as renewables topped coal nationwide for the first time in over a century, without setting any future goals, and jettisoned its energy efficiency standard. West Virginia — which established modest renewable requirements in 2009 — repealed them altogether in 2015, the year they were set to take effect.
