I.B.M. scientists have measured the force needed to nudge one atom.

About one-130-millionth of an ounce of force pushes a cobalt atom across a smooth, flat piece of platinum.

Pushing the same atom along a copper surface is easier, just one-1,600-millionth of an ounce of force.

The scientists report these minuscule findings in a recent issue of the journal Science.

I.B.M. scientists have been pushing atoms around for some time, since Donald M. Eigler of the company’s Almaden Research Center in San Jose, Calif., spelled “IBM” using 35 xenon atoms in 1989. Since then, researchers at the company have continued to explore how they might be able to construct structures and electronic components out of individual atoms.

Knowing the precise forces required to move atoms “helps us to understand what is possible and what is not possible,” said Andreas J. Heinrich, a physicist at Almaden and an author of the new Science paper. “It’s a stepping stone for us, but it’s by no means the end goal.”

In the experiment, Dr. Heinrich and his collaborators at Almaden and the University of Regensburg in Germany used the sharp tip of an atomic force microscope to push a single atom. To measure the force, the tip was attached to a small tuning fork, the same kind that is found in a quartz wristwatch. In fact, in the first prototype, Franz J. Giessibl, a scientist at Regensburg who was a pioneer in the use of atomic force microscopes, bought an inexpensive watch and pulled out the quartz tuning fork for use in the experiment.

The tip vibrates 20,000 times a second until it comes into contact with an atom. As the tip pushes, the tuning fork bends, like a diving board, and the vibration frequency dips.

A single atom does not roll, and even a perfectly smooth surface is not perfectly smooth. Instead, the atom rests in small indentations in the lattice, in effect like an egg in an egg carton. The resistance — what becomes friction when multiplied by millions and billions of atoms — comes from the energy needed to rearrange the bonds between the cobalt atom and surface.

When the tip pushes hard enough, the atom hops, almost instantaneously to the next indentation. “It’s not smooth,” said Markus Ternes, another Almaden scientist working on the research. “It’s faster than we can detect.”

From the changes in the frequency of the tuning fork vibrations, the scientists calculated the force that the tip applied to the cobalt atom.

Copper is less sticky than platinum, because of differences between the underlying bonds, and hence allowed the greater ease is pushing the cobalt atom along.

EU outlines $300 billion plan to dump Russian energy

REPowerEU Plan accelerates the EU's shift from Russian fossil fuels with renewable energy, energy efficiency, solar, wind, heat pumps, faster permits, and energy security measures by 2027, backed by grants, loans, and grid investments.

 

Key Points

EU plan to quit Russian fossil fuels via renewables and efficiency, with faster permits, by 2027.

✅ €300bn in grants and loans for efficiency and renewables

✅ Streamlined permits; solar mandate on new buildings

✅ Targets 2027 independence; cuts Russian gas, oil, coal

 

The European Union’s executive arm moved Wednesday to jump-start plans for the 27-nation bloc to abandon Russian energy amid the Kremlin’s war in Ukraine, proposing a nearly 300 billion-euro ($315 billion) package that includes more efficient use of fuels and faster rollout of renewable power, even as rolling back electricity prices remains challenging.

The European Commission’s investment initiative is meant to help the 27 EU countries start weaning themselves off Russian fossil fuels this year, a move many see as a wake-up call to ditch fossil fuels across Europe. The goal is to deprive Russia, the EU’s main supplier of oil, natural gas and coal, of tens of billions in revenue and strengthen EU climate policies.

“We are taking our ambition to yet another level to make sure that we become independent from Russian fossil fuels as quickly as possible,” European Commission President Ursula von der Leyen said in Brussels when announcing the package, dubbed REPowerEU.

With no end in sight to Russia’s war in Ukraine and European energy security shaken, amid what some describe as an energy nightmare for the region, the EU is rushing to align its geopolitical and climate interests for the coming decades. It comes amid troubling signs that have raised concerns about energy supplies that the EU relies on and have no quick replacements for, including Russia cutting off member nations Poland and Bulgaria after they refused a demand to pay for natural gas in rubles.

The bloc’s dash to ditch Russian energy stems from a combination of voluntary and mandatory actions. Both reflect the political discomfort of helping fund Russia’s military campaign in a country that neighbors the EU and wants to join the bloc.

An EU ban on coal from Russia is due to start in August, and the bloc has pledged to try to reduce demand for Russian gas by two-thirds by year's end, while debating gas price cap strategies to curb volatility. Meanwhile, a proposed EU oil embargo has hit a roadblock from Hungary and other landlocked countries that worry about the cost of switching to alternative sources.

In a bid to swing Hungary behind the oil phaseout, the REPowerEU package expects oil investment funding of around 2 billion euros for member nations highly dependent on Russian oil.

Energy savings and renewables form the cornerstones of the package, which would be funded mainly by an economic stimulus program put in place to help member countries overcome the slump triggered by the coronavirus pandemic.

The European Commission said the price tag for abandoning Russian fossil fuels completely by a 2027 target date is 210 billion euros. Its package includes 56 billion euros for energy efficiency and 86 billion euros for renewables.

Von der Leyen cited a total funding pot of 72 billion euros in grants and 225 billion euros for loans.

The European Commission also proposed ways to streamline the approval processes in EU countries for renewable projects, which can take up to a decade to get through red tape, as part of a broader effort to revamp the electricity market across Europe. The commission said approval times need to fall to as little as a year or less.

It put forward a specific plan on solar energy, seeking to double photovoltaic capacity by 2025 and pushing for a phased-in obligation to install solar panels on new buildings.

Simone Tagliapietra, an energy expert at the Bruegel think tank in Brussels, called REPowerEU a “jumbo package” whose success will ultimately depend on political will in the bloc’s national capitals, with examples such as Germany’s 200 billion euro energy price shield illustrating the scale of national responses.

“Most of the actions entailed in the plan require either national implementation or strong coordination among member states,” Tagliapietra said. “The extent to which countries really engage is going to be defining.”

The German energy think tank Agora Energiewende said the EU’s plan “gives too little attention to concrete initiatives that reduce fossil fuel demand in the short term and thereby misses the opportunity to simultaneously enhance Europe’s energy security and meet Europe’s climate objectives.”

The group's research shows rapidly expanding solar, wind parks and use of heat pumps for low-temperature heat in industry and buildings could be done faster than constructing new liquefied natural gas terminals or gas infrastructure, said Matthias Buck, its director for Europe.

The European Commission’s recommendations on short-term national actions to cut demand for Russian energy, which include potential emergency measures to limit electricity prices as well, coincide with deliberations underway in the bloc since last year on setting more ambitious EU energy-efficiency and renewable targets for 2030.

Those targets, being negotiated by the European Parliament and national governments, are part of the bloc’s commitments to a 55% cut in greenhouse gases by decade's end, compared with 1990 emissions, and to climate neutrality by 2050.

Von der Leyen urged the European Parliament and national governments to deepen the commission’s July proposal for an energy efficiency target of 9% and renewable energy goal of 40% by 2030. She said those objectives should be 13% and 45%, respectively.

Belgium, the Netherlands, Germany and Denmark plan to build North Sea wind farms to help cut carbon emissions.

Ontario hydro rates set to increase Nov. 1, Ontario Energy Board says

Ontario Electricity Rebate clarifies hydro rates as OEB aligns bills with inflation, shows true cost per kilowatt hour, and replaces Fair Hydro Plan; transparent on-bill credit offsets increases tied to nuclear refurbishment and supply costs.

 

Key Points

A line-item credit on Ontario hydro bills that offsets higher electricity costs and reflects OEB-set rates.

✅ Starts Nov. 1 with rates in line with inflation

✅ Shows true per-kWh cost plus separate rebate line

✅ Driven by nuclear refurbishment and supply costs

 

The Ontario Energy Board says electricity rate changes for households and small businesses will be going up starting next week.

The agency says rates are scheduled to increased by about $1.99 or nearly 2% for a typical residential customer who uses 700 kilowatt hours per month.

The provincial government said in March it would continue to subsidize hydro rates, through legislation to lower rates, and hold any increases to the rate of inflation.

The OEB says the new rates, which the board says are “in line” with inflation, will take effect Nov. 1 as changes for electricity consumers roll out and could be noticed on bills within a few weeks of that date.

Prices are increasing partly due to government legislation aimed at reflecting the actual cost of supply on bills, and partly due to the refurbishment of nuclear facilities, contributing to higher hydro bills for some consumers.

So, effective November 1, Ontario electricity bills will show the true cost of power, after a period of a fixed COVID-19 hydro rate, and will include the new Ontario Electricity Rebate.

Previously the electricity rebate was concealed within the price-per-kilowatt-hour line item on electricity statements, prompting Hydro One bill redesign discussions to improve clarity. This meant customers could not see how much the government rebate was reducing their monthly costs, and bills did not display the true cost of electricity used.

"People deserve facts and accountability, especially when it comes to hydro costs," said Energy Minister Rickford.

The new Ontario Electricity Rebate will appear as a transparent on-bill line item and will replace the former government's Fair Hydro Plan says a government news release. This change comes in response to the Auditor General's special report on the former government's Fair Hydro Plan which revealed that "the government created a needlessly complex accounting/financing structure for the electricity rate reduction in order to avoid showing a deficit or an increase in net debt."

"The Electricity Distributors Association commends the government's commitment to making Ontario's electricity bills more transparent," said Teresa Sarkesian, President of the Electricity Distributors Association. "As the part of our electricity system that is closest to customers, local hydro utilities appreciated the opportunity to work with the government on implementing this important initiative. We worked to ensure that customers who receive their electricity bill will have a clear understanding of the true cost of power and the amount of their on-bill rebate. Local hydro utilities are focused on making electricity more affordable, reducing red tape, and providing customers with a modern and reliable electricity system that works for them."

The average customer will see the electricity line on their bill rise, showing the real cost per kilowatt hour. The new Ontario Electricity Rebate will compensate for that rise, and will be displayed as a separate line item on hydro bills. The average residential bill will rise in line with the rate of inflation.

Michigan Public Service Commission grants Consumers Energy request for more wind generation

Consumers Energy Wind Expansion gains MPSC approval in Michigan, adding up to 525 MW of wind power, including Gratiot Farms, while solar capacity requests face delays over cost projections under the renewable portfolio standard targets.

 

Key Points

A regulatory-approved plan enabling Consumers Energy to add 525 MW of wind while solar additions await cost review.

✅ MPSC approves up to 525 MW in new wind projects

✅ Gratiot Farms purchase allowed before May 1

✅ Solar request delayed over high cost projections

 

Consumers Energy Co.’s efforts to expand its renewable offerings gained some traction this week when the Michigan Public Service Commission (MPSC) approved a request for additional wind generation capacity.

Consumers had argued that both more wind and solar facilities are needed to meet the state’s renewable portfolio standard, which was expanded in 2016 to encompass 12.5 percent of the retail power of each Michigan electric provider. Those figures will continue to rise under the law through 2021 when the figure reaches 15 percent, alongside ongoing electricity market reforms discussions. However, Consumers’ request for additional solar facilities was delayed at this time due to what the Commission labeled unrealistically high-cost projections.

Consumers will be able to add as much as 525 megawatts of new wind projects amid a shifting wind market, including two proposed 175-megawatt wind projects slated to begin operation this year and next. Consumers has also been allowed to purchase the Gratiot Farms Wind Project before May 1.

The MPSC said a final determination would be made on Consumers’ solar requests during a decision in April. Consumers had sought an additional 100 megawatts of solar facilities, hoping to get them online sometime in 2024 and 2025.

Canadians Support Tariffs on Energy and Minerals in U.S. Trade Dispute

Canada Tariffs on U.S. Energy and Minerals signal retaliatory tariffs amid trade tensions, targeting energy exports and critical minerals, reflecting sovereignty concerns and shifting consumer behavior, reduced U.S. purchases, and demand for Canadian-made goods.

 

Key Points

They are proposed retaliatory tariffs on energy exports and critical minerals to counter U.S. trade pressures.

✅ 75% support tariffs; 70% back dollar-for-dollar retaliation

✅ Consumer shift: fewer U.S. purchases, more Canadian-made goods

✅ Concerns over sovereignty and U.S. trade tactics intensify

 

A recent survey has revealed that a significant majority of Canadians—approximately 75%—support the implementation of tariffs on energy exports and critical minerals in response to electricity exports at risk amid trade tensions with the United States. This finding underscores the nation's readiness to adopt assertive measures to protect its economic interests amid escalating trade disputes.​

Background on Trade Tensions

The trade relationship between Canada and the United States has experienced fluctuations in recent years, with both nations navigating complex issues related to tariffs and energy tariffs and trade tensions as well as trade agreements and economic policies. The introduction of tariffs has been a contentious strategy, often leading to reciprocal measures and impacting various sectors of the economy.​

Public Sentiment Towards Retaliatory Tariffs

The survey, conducted by Leger between February 14 and 17, 2025, sampled 1,500 Canadians and found that 70% favored implementing dollar-for-dollar retaliatory tariffs against the U.S. Notably, 45% of respondents were strongly in favor, while 25% were somewhat in favor. This strong support reflects widespread dissatisfaction with U.S. trade policies and growing support for Canadian energy projects among voters, alongside a collective sentiment favoring decisive action. ​

Concerns Over U.S. Economic Strategies

The survey also highlighted that 81% of Canadians are apprehensive about potential U.S. economic tactics aimed at drawing Canada into a closer political union. These concerns are fueled by statements from U.S. President Donald Trump, who has suggested annexation and employed tariffs that could spike NY energy prices to influence Canadian sovereignty. Such sentiments have heightened fears about the erosion of Canada's political autonomy under economic duress. ​

Impact on Consumer Behavior

In response to these trade tensions, including reports that Ford threatened to cut U.S. electricity exports, many Canadians have adjusted their purchasing habits. The survey indicated that 63% of respondents are buying fewer American products in stores, and 62% are reducing online purchases from U.S. retailers. Specific declines include a 52% reduction in Amazon purchases, a 50% drop in fast-food consumption from American chains, and a 43% decrease in spending at U.S.-based retail stores. Additionally, 30% of Canadians have canceled planned trips to the United States, while 68% have increased their purchases of Canadian-made products. These shifts demonstrate a tangible impact on consumer behavior driven by nationalistic sentiments and support for retaliatory measures. ​

Economic and Political Implications

The widespread support for retaliatory tariffs and the corresponding changes in consumer behavior have significant economic and political implications. Economically, while tariffs can serve as a tool for asserting national interests, they also risk triggering trade wars that can harm various sectors, including agriculture, manufacturing, and technology, with experts cautioning against cutting Quebec's energy exports in response. Politically, the situation presents a challenge for Canadian leadership to balance assertiveness in defending national interests with the necessity of maintaining a stable and mutually beneficial relationship with the U.S., Canada's largest trading partner.​

As Canada approaches its federal elections, trade policy is emerging as a pivotal issue. Voters are keenly interested in how political parties propose to navigate the complexities of international trade, particularly with the United States and how a potential U.S. administration's stance, such as Biden's approach to the energy sector could shape outcomes. The electorate's strong stance on retaliatory tariffs may influence party platforms and campaign strategies, emphasizing the need for clear and effective policies that address both the immediate concerns of trade disputes and the long-term goal of sustaining positive international relations.​

The survey results reflect a nation deeply engaged with its trade dynamics and protective of its sovereignty. While support for retaliatory tariffs is robust, it is essential for policymakers to carefully consider the broader consequences of such actions. Striking a balance between defending national interests and fostering constructive international relationships will be crucial as Canada navigates these complex trade challenges in the coming years.

Hydro One extends ban on electricity disconnections until further notice

Hydro One Disconnection Ban Extension keeps Ontario electricity customers connected during COVID-19, extending the moratorium on power shutoffs and expanding financial relief programs amid ongoing pandemic restrictions and persistent hot weather across the province.

 

Key Points

An open-ended Ontario utility moratorium preventing residential power shutoffs and offering bill relief during COVID-19.

✅ No residential disconnections until further notice

✅ Extended bill assistance and flexible payment options

✅ Response to COVID-19 restrictions and extreme heat

 

Ontario's primary electricity provider says it's extending a ban on disconnecting homes from the power grid until further notice.

Hydro One first issued the ban towards the beginning of the province's COVID-19 outbreak, saying self-isolating customers needed to be able to rely on electricity while they were kept at home during the pandemic.

A spokesman for the utility says the ban was initially set to expire at the end of July, but has now been extended in a manner similar to winter disconnection bans without a fixed end-date.

Hydro One says the move is necessary given the ongoing restrictions posed by the pandemic, and notes it has supported provincial COVID-19 efforts in recent months, as well as persistent hot weather across much of the province.

It says it's also planning to extend a financial relief program to help customers struggling to pay their hydro bills, reflecting demand for more choice and flexibility among ratepayers.

The province also extended off-peak electricity rates to provide relief for families, small businesses and farms during this period.

Blizzard and Extreme Cold Hit Calgary and Alberta

Calgary Winter Storm and Extreme Cold delivers heavy snowfall, ECCC warnings, blowing snow, icy roads, and dangerous wind chill across southern Alberta, as a low-pressure system and northerly inflow fuel hazardous travel and frostbite risks.

 

Key Points

A severe Alberta storm with heavy snow, strong winds, ECCC warnings, dangerous wind chill, and high frostbite risk.

✅ ECCC extends snowfall and winter storm warnings regionwide.

✅ Wind chill -28 to -47; frostbite possible within 5-30 minutes.

✅ AMA rescues surge; non-essential travel strongly discouraged.

 

Calgary and much of southern Alberta faced a significant winter storm that brought heavy snowfall, strong winds, and dangerously low temperatures. Environment and Climate Change Canada (ECCC) issued extended and expanded snowfall and winter storm warnings as persistent precipitation streamed along the southern borders. The combination of a low-pressure system off the West Coast, where a B.C. 'bomb cyclone' had left tens of thousands without power, and a northerly inflow at the surface led to significant snow accumulations in a short period.

The storm resulted in poor driving conditions across much of southern Alberta, with snow-packed and icy roads, as well as limited visibility due to blowing snow. ECCC advised postponing non-essential travel until conditions improved. As of 10 a.m. on January 17, the 511 Alberta map showed poor driving conditions throughout the region, while B.C. electricity demand hit an all-time high amid the cold.

In Calgary, the city recorded four centimeters of snow on January 16, with an additional four centimeters expected on January 17. Temperatures remained far below seasonal averages until the end of the week, and Calgary electricity use tends to surge during such cold snaps according to Enmax, with improvements starting on Sunday.

The extreme cold posed significant risks, with wind chills of -28 to -39 capable of causing frostbite in 10 to 30 minutes, as a Quebec power demand record illustrated during the deep freeze. When wind chills dropped to -40 to -47, frostbite could occur in as little as five to 10 minutes. Residents were advised to watch for signs of frostbite, including color changes on fingers and toes, pain, numbness, tingling sensations, or swelling. Those most at risk included young children, older adults, people with chronic illnesses, individuals working or exercising outdoors, and those without proper shelter.

In response to the severe weather, the Alberta Motor Association (AMA) experienced a surge in calls for roadside assistance. Between January 12 and 14, there were approximately 32,000 calls, with about 22,000 of those requiring rescues between January 12 and 14. The high volume of requests led the AMA to temporarily cease providing wait time updates on their website due to the inability to provide accurate information, while debates over Alberta electricity prices also intensified during the cold.

The storm also had broader implications across Canada. Heavy snow was expected to fall across wide swaths of southern British Columbia and parts of southern Alberta, as BC Hydro's winter payment plan offered billing relief to customers during the stretch. Northern Alberta was under extreme cold warnings, with temperatures expected to dip to -40°C through the rest of the week. Similar extreme cold was forecast for southern Ontario, with wind chill values reaching -30°C.

As the storm progressed, conditions began to improve. The wind warning for central Alberta ended by January 17, though a blowing snow advisory remained in effect for the southeast corner of the province. Northwest winds gusting up to 90 km/h combined with falling snow continued to cause poor visibility in some areas, while California power outages and landslides were reported amid concurrent severe storms along the coast. Conditions were expected to improve by mid-morning.

In the aftermath of the storm, residents were reminded of the importance of preparedness and caution during severe winter weather. Staying informed through official weather advisories, adjusting travel plans, and taking necessary precautions can help mitigate the risks associated with such extreme conditions.
