Power was finally restored to homes that lost their electrical service in the recent snow and ice storm, Toronto Hydro said.

Crews working through the weekend stayed on the job until 2 a.m. March 5 to repair power lines damaged by ice and falling trees, said Toronto Hydro spokesman Paul Reesor.

The only customers who could still be without electricity, Reesor said, are those who haven't told the power company.

“Everyone has been restored that was in our queue,” he said.

As many as 60,000 homes and businesses were left without power when a powerful storm swept through the city and much of the province.

For some customers, the blackouts lasted all weekend.

When Patricia Kellogg heard the hum of the furnace stop at 3:10 a.m. March 2, she knew the silence meant trouble. But she never expected the silence to last until yesterday, when hydro crews showed up at her Riverdale home to reconnect the electricity and heat.

"We were roughing it," she joked last night in her warm and well-lit house. "I found it a bit nerve-wracking – there was no fan from the furnace, no radio, no TV. We could read the newspaper, but it was quiet."

Her husband, Bruce Henderson, said his first reaction was they should go to a hotel. But given they had hot water, because it's heated by gas, a wood-burning fireplace and a phone to order in food, it wasn't so bad, he said.

"What are they going to do if we get a major storm? Because this was very minor," said Henderson, the only homeowner on his street to lose power.

"Hydro absolutely took too long."

Luckily, they had an emergency kit that included batteries, candles, lamp oil and a lamp. But if they had gone another day without power, they would have checked into a hotel.

They made do with what they had and improvised. Kellogg figured she could boil water in her fondue set so they were able to make coffee.

Neighbours checked in regularly and took some of their food from their fridge so it wouldn't go bad.

Brian Frimeth also considered going to a hotel when he lost power to his Broadview and Danforth home the evening of March 1. But since Hydro told him it would only be a day before the electricity would be restored he figured he could wait it out.

But when he woke up in a bedroom that was -4C, he knew he couldn't wait much longer – a gut feeling confirmed when Hydro told him it might take another three days.

"Toronto Hydro lied to us repeatedly, telling us, ‘Power will be restored shortly... crews are there at your location, working right now.' I went over to the feeder line each time I called and was told the 'crew was there,' (but) guess what, there never was a crew there."

He began calling around for a hotel room, but most wouldn't take dogs.

Frimeth, a lawyer, and his partner eventually checked into the Four Seasons Hotel in Yorkville, with no extra charge for the dogs. When he called Hydro to check on the status of their neighbourhood, which was entirely blacked out, he was told it would be up to another two days.

Moments later, he was told they were mistaken and that it had just been turned on.

The two couples were among thousands of Toronto residents who had to wait until the weekend before power was restored.

As of 4 p.m. March 4, about 1,000 hydro customers – most of them businesses – were still without power from the March 1 ice storm.

Most of the homes without power were in older areas of the city, like The Beach, High Park and around Merton St., north of St. Clair Ave., where hanging overhead wires were torn down by icy, falling tree limbs, said Toronto Hydro spokesperson Cathy Parry.

Some homes in those areas, as well as on Palmerston Blvd. in the Annex and older areas of North York, took longer to repair because utility poles bringing power to those houses are in the backyards, Parry said.

Meanwhile, Front St. was reopened but Bremner St. remained closed as ice continued to fall from the CN Tower. The hotel-lined stretch of Front could be closed again if winds shift, police said.

Elsewhere in the province, about 2,500 Hydro One customers were without power as of March 4, primarily in southwestern Ontario, north of London.

Brazil tax strategy to bring down fuel, electricity prices seen having limited effects

Brazil ICMS Tax Cap limits state VAT on fuels, natural gas, electricity, communications, and transit, promising short-term price relief amid inflation, with federal compensation to states and potential legal challenges affecting investments and ANP auctions.

 

Key Points

A policy capping state VAT at 17-18 percent on fuels, electricity, and services to temper prices and inflation.

✅ Caps VAT to 17-18% on fuels, power, telecom, transit

✅ Short-term relief; medium-long term impact uncertain

✅ Federal compensation; potential court challenges, investment risk

 

Brazil’s congress approved a bill that limits the ICMS tax rate that state governments can charge on fuels, natural gas, electricity, communications, and public transportation. 

Local lawyers told BNamericas that the measure may reduce fuel and power prices in the short term, similar to Brazil power sector relief loans seen during the pandemic, but it is unlikely to produce any major effects in the medium and long term. 

In most states the ceiling was set at 17% or 18% and the federal government will pay compensation to the states for lost tax revenue until December 31, via reduced payments on debts that states owe the federal government.

The bill will become law once signed by President Jair Bolsonaro, who pushed strongly for the proposal with an eye on his struggling reelection campaign for the October presidential election. Double-digit inflation has turned into a major election issue and fuel and electricity prices have been among the main inflation drivers, as seen in EU energy-driven inflation across the bloc this year. Congress’ approval of the bill is seen by analysts as political victory for the Brazilian leader.

How much difference will it make?

Marcus Francisco, tax specialist and partner at Villemor Amaral Advogados, said that in the formation of fuel and electricity prices there are other factors, including high natural gas prices, that drive increases.

“In the case of fuels, if the barrel of oil [price] increases, automatically the final price for the consumer will go up. For electricity, on the other hand, there are several subsidies and policy choices such as Florida rejecting federal solar incentives that are part of the price and that can increase the rate [paid],” he said. 

There is also a possibility that some states will take the issue to the supreme court since ICMS is a key source of revenue for them, Francisco added.

Tiago Severini, a partner at law firm Vieira Rezende, said the comparison between the revenue impact and the effective price reduction, based on the estimates made by the states and the federal government, seems disproportionate, and, as seen in Europe, rolling back European electricity prices is often tougher than it appears. 

“In other words, a large tax collection impact is generated, which is quite unequal among the different states, for a not so strong price reduction,” he said.

“Due to the lack of clarity regarding the precision of the calculations involved, it’s difficult even to assess the adequacy of the offsets the federal government has been considering, and international cases such as France's new electricity pricing scheme illustrate how complex it can be to align fiscal offsets with regulatory constraints, to cover the cost it would have with the compensation for the states” Severini added.

The compensation ideas that are known so far include hiking other taxes, such as the social contribution on net profits (CSLL) that is paid by oil and gas firms focused on exploration and production.

“This can generate severe adverse effects, such as legal disputes, reduced investments in the country, and reduced attractiveness of the new auctions by [sector regulator] ANP, and costly interventions like the Texas electricity market bailout after extreme weather events,” Severini said.

Greening Ontario's electricity grid would cost $400 billion: report

Ontario Electricity Grid Decarbonization outlines the IESO's net-zero pathway: $400B investment, nuclear expansion, renewables, hydrogen, storage, and demand management to double capacity by 2050 while initiating a 2027 natural gas moratorium.

 

Key Points

A 2050 plan to double capacity, retire gas, and invest $400B in nuclear, renewables, and storage for a net-zero grid.

✅ $400B over 25 years to meet net-zero electricity by 2050

✅ Capacity doubles to 88,000 MW; demand grows ~2% annually

✅ 2027 gas moratorium; build nuclear, renewables, storage

 

Ontario will need to spend $400 billion over the next 25 years in order to decarbonize the electricity grid and embrace clean power according to a new report by the province’s electricity system manager that’s now being considered by the Ford government.

The Independent System Electricity Operator (IESO) was tasked with laying out a path to reducing Ontario’s reliance on natural gas for electricity generation and what it would take to decarbonize the entire electricity grid by 2050.

Meeting the goal, the IESO concluded, will require an “aggressive” approach of doubling the electricity capacity in Ontario over the next two-and-a-half decades — from 42,000 MW to 88,000 MW — by investing in nuclear, hydrogen and wind and solar power while implementing conservation policies and managing demand.

“The process of fully eliminating emissions from the grid itself will be a significant and complex undertaking,” IESO president Lesley Gallinger said in a news release.

The road to decarbonization, the IESO said, begins with a moratorium on natural gas power generation starting in 2027 as long as the province has “sufficient, non-emitting supply” to meet the growing demands on the grid.

The approach, however, comes with significant risks.

The IESO said hydroelectric and nuclear facilities can take 10 to 15 years to build and if costs aren’t controlled the plan could drive up the price of clean electricity, turning homeowners and businesses away from electrification.

“Rapidly rising electricity costs could discourage electrification, stifle economic growth or hurt consumers with low incomes,” the report states.

The IESO said the province will need to take several “no regret” actions, including selecting sites and planning to construct new large-scale nuclear plants as well as hydroelectric and energy storage projects and expanding energy-efficiency programs beyond 2024.

Ontario’s minister of energy didn’t immediately commit to implementing the recommendations, citing the need to consult with stakeholders first.

“I look forward to launching a consultation in the new year on next steps from today’s report, including the potential development of major nuclear, hydroelectric and transmissions projects,” Todd Smith said in a statement.

Currently, electricity demand is increasing by roughly two per cent per year, raising concerns Ontario could be short of electricity in the coming years as the manufacturing and transportation sectors electrify and as more sectors consider decarbonization.

At the same time, the province’s energy supply is facing “downward pressure” with the Pickering nuclear power plant slated to wind down operations and the Darlington nuclear generating station under active refurbishment.

To meet the energy need, the Ford government said it intended to extend the life of the Pickering plant until 2026.

But to prepare for the increase, the Ontario government was told the province would also need to build new natural gas facilities to bridge Ontario’s electricity supply gap in the near term — a recommendation the Ford government agreed to.

The IESO said a request for proposals has been opened and the province is looking for host communities, with the expectation that existing facilities would be upgraded before projects on undeveloped land would be considered.

The IESO said the contract for any new facilities would expire in 2040, and all natural gas facilities would be retired in the 2040s.

Baltic States Disconnect from Russian Power Grid, Join EU System

Baltic States EU Grid Synchronization strengthens energy independence and electricity security, ending IPS/UPS reliance. Backed by interconnectors like LitPol Link, NordBalt, and Estlink, it aligns with NATO interests and safeguards against subsea infrastructure threats.

 

Key Points

A shift by Estonia, Latvia, and Lithuania to join the EU grid, boosting energy security and reducing Russian leverage.

✅ Synchronized with EU grid on Feb 9, 2025 after islanding tests.

✅ New interconnectors: LitPol Link, NordBalt, Estlink upgrades.

✅ Reduces IPS/UPS risks; bolsters NATO and critical infrastructure.

 

In a landmark move towards greater energy independence and European integration, the Baltic nations of Estonia, Latvia, and Lithuania have officially disconnected from Russia's electricity grid, a path also seen in Ukraine's rapid grid link to the European system. This decisive action, completed in February 2025, not only ends decades of reliance on Russian energy but also enhances the region's energy security and aligns with broader geopolitical shifts.

Historical Context and Strategic Shift

Historically, the Baltic states were integrated into the Russian-controlled IPS/UPS power grid, a legacy of their Soviet past. However, in recent years, these nations have sought to extricate themselves from Russian influence, aiming to synchronize their power systems with the European Union (EU) grid. This transition gained urgency following Russia's annexation of Crimea in 2014 and further intensified after the invasion of Ukraine in 2022, as demonstrated by Russian strikes on Ukraine's grid that underscored energy vulnerability.

The Disconnection Process

The process culminated on February 8, 2025, when Estonia, Latvia, and Lithuania severed their electrical ties with Russia. For approximately 24 hours, the Baltic states operated in isolation, conducting rigorous tests to ensure system stability and resilience, echoing winter grid protection efforts seen elsewhere. On February 9, they successfully synchronized with the EU's continental power grid, marking a historic shift towards European energy integration.

Geopolitical and Security Implications

This transition holds significant geopolitical weight. By disconnecting from Russia's power grid, the Baltic states reduce potential leverage that Russia could exert through energy supplies. The move also aligns with NATO's strategic interests, enhancing the security of critical infrastructure in the region, amid concerns about Russian hacking of US utilities that highlight cyber risks.

Economic and Technical Challenges

The shift was not without challenges. The Baltic states had to invest heavily in infrastructure to ensure compatibility with the EU grid and navigate regional market pressures such as a Nordic grid blockade affecting transmission capacity. This included constructing new interconnectors and upgrading existing facilities. For instance, the LitPol Link between Lithuania and Poland, the NordBalt cable connecting Lithuania and Sweden, and the Estlink between Estonia and Finland were crucial in facilitating this transition.

Impact on Kaliningrad

The disconnection has left Russia's Kaliningrad exclave isolated from the Russian power grid, relying solely on imports from Lithuania. While Russia claims to have measures in place to maintain power stability in the region, the long-term implications remain uncertain.

Ongoing Security Concerns

The Baltic Sea region has experienced heightened security concerns, particularly regarding subsea cables and pipelines. Increased incidents of damage to these infrastructures have raised alarms about potential sabotage, including a Finland cable damage investigation into a suspected Russian-linked vessel. Authorities continue to investigate these incidents, emphasizing the need for robust protection of critical energy infrastructure.

The successful disconnection and synchronization represent a significant step in the Baltic states' journey towards full integration with European energy markets. This move is expected to enhance energy security, promote economic growth, and solidify geopolitical ties with the EU and NATO. As the region continues to modernize its energy infrastructure, ongoing vigilance against security threats will be paramount, as recent missile and drone attacks on Kyiv's grid demonstrate.

The Baltic states' decision to disconnect from Russia's power grid and synchronize with the European energy system is a pivotal moment in their post-Soviet transformation. This transition not only signifies a break from historical dependencies but also reinforces their commitment to European integration and collective security. As these nations continue to navigate complex geopolitical landscapes, their strides towards energy independence serve as a testament to their resilience and strategic vision.

Scientists generate 'electricity from thin air.' Humidity could be a boundless source of energy.

Air Humidity Energy Harvesting converts thin air into clean electricity using air-gen devices with nanopores, delivering continuous renewable energy from ambient moisture, as demonstrated by UMass Amherst researchers in Advanced Materials.

 

Key Points

A method using nanoporous air-gen devices to harvest continuous clean electricity from ambient atmospheric moisture.

✅ Nanopores drive charge separation from ambient water molecules

✅ Works across materials: silicon, wood, bacterial films

✅ Predictable, continuous power unlike intermittent solar or wind

 

Sure, we all complain about the humidity on a sweltering summer day. But it turns out that same humidity could be a source of clean, pollution-free energy, aligning with efforts toward cheap, abundant electricity worldwide, a new study shows.

"Air humidity is a vast, sustainable reservoir of energy that, unlike wind and solar power resources, is continuously available," said the study, which was published recently in the journal Advanced Materials.

While humidity harvesting promises constant output, advances like a new fuel cell could help fix renewable energy storage challenges, researchers suggest.

“This is very exciting,” said Xiaomeng Liu, a graduate student at the University of Massachusetts-Amherst, and the paper’s lead author. “We are opening up a wide door for harvesting clean electricity from thin air.”

In fact, researchers say, nearly any material can be turned into a device that continuously harvests electricity from humidity in the air, a concept echoed by raindrop electricity demonstrations in other contexts.

“The air contains an enormous amount of electricity,” said Jun Yao, assistant professor of electrical and computer engineering at the University of Massachusetts-Amherst and the paper’s senior author. “Think of a cloud, which is nothing more than a mass of water droplets. Each of those droplets contains a charge, and when conditions are right, the cloud can produce a lightning bolt – but we don’t know how to reliably capture electricity from lightning.

"What we’ve done is to create a human-built, small-scale cloud that produces electricity for us predictably and continuously so that we can harvest it.”

The heart of the human-made cloud depends on what Yao and his colleagues refer to as an air-powered generator, or the "air-gen" effect, which relates to other atmospheric power concepts like night-sky electricity studies in the field.

In broader renewable systems, flexible resources such as West African hydropower can support variable wind and solar output, complementing atmospheric harvesting concepts as they mature.

The study builds on research from a study published in 2020. That year, scientists said this new technology "could have significant implications for the future of renewable energy, climate change and in the future of medicine." That study indicated that energy was able to be pulled from humidity by material that came from bacteria; related bio-inspired fuel cell design research explores better electricity generation, the new study finds that almost any material, such as silicon or wood, also could be used.

The device mentioned in the study is the size of a fingernail and thinner than a single hair. It is dotted with tiny holes known as nanopores, it was reported. "The holes have a diameter smaller than 100 nanometers, or less than a thousandth of the width of a strand of human hair."

Wind Power Surges in U.S. Electricity Mix

U.S. Wind Power 2025 drives record capacity additions, with FERC data showing robust renewable energy growth, IRA incentives, onshore and offshore projects, utility-scale generation, grid integration, and manufacturing investment boosting clean electricity across key states.

 

Key Points

Overview of record wind additions, IRA incentives, and grid expansion defining the U.S. clean electricity mix in 2025.

✅ FERC: 30.1% of new U.S. capacity in Jan 2025 from wind

✅ Major projects: Cedar Springs IV, Boswell, Prosperity, Golden Hills

✅ IRA incentives drive onshore, offshore builds and manufacturing

 

In early 2025, wind power has significantly strengthened its position in the United States' electricity generation portfolio. According to data from the Federal Energy Regulatory Commission (FERC), wind energy accounted for 30.1% of the new electricity capacity added in January 2025, and as the most-used renewable source in the U.S., it also surpassed the previous record set in 2024. This growth is attributed to substantial projects such as the 390.4 MW Cedar Springs Wind IV and the 330.0 MW Boswell Wind Farm in Wyoming, along with the 300.0 MW Prosperity Wind Farm in Illinois and the 201.0 MW Golden Hills Wind Farm Expansion in Oregon. 

The expansion of wind energy capacity is part of a broader trend where solar and wind together accounted for over 98% of the new electricity generation capacity added in the U.S. in January 2025. This surge is further supported by the federal government's Inflation Reduction Act (IRA) and broader policy support for renewables, which has bolstered incentives for renewable energy projects, leading to increased investments and the establishment of new manufacturing facilities. 

By April 2025, clean electricity sources, including wind and solar, were projected to surpass 51% of total utility-scale electricity generation in the U.S., building on a 25.5% renewable share seen in recent data, marking a significant milestone in the nation's energy transition. This achievement is attributed to a combination of factors: a seasonal drop in electricity demand during the spring shoulder season, increased wind speeds in key areas like Texas, and higher solar production due to longer daylight hours and expanded capacity in states such as California, Arizona, and Nevada, supported by record installations across the solar and storage industry. 

Despite a 7% decline in wind power production in early April compared to the same period in 2024—primarily due to weaker wind speeds in regions like Texas—the overall contribution of wind energy remained robust, supported by an 82% clean-energy pipeline that includes wind, solar, and batteries. This resilience underscores the growing reliability of wind power as a cornerstone of the U.S. electricity mix. 

Looking ahead, the U.S. Department of Energy projects that wind energy capacity will continue to grow, with expectations of adding between 7.3 GW and 9.9 GW in 2024, and potentially increasing to 14.5 GW to 24.8 GW by 2028. This growth is anticipated to be driven by both onshore and offshore wind projects, with onshore wind representing the majority of new additions, continuing a trajectory since surpassing hydro capacity in 2016 in the U.S.

Early 2025 has witnessed a notable increase in wind power's share of the U.S. electricity generation mix. This trend reflects the nation's ongoing commitment to expanding renewable energy sources, especially after renewables surpassed coal in 2022, supported by favorable policies and technological advancements. As the U.S. continues to invest in and develop wind energy infrastructure, the role of wind power in achieving a cleaner and more sustainable energy future becomes increasingly pivotal.

Britain Goes Full Week Without Coal Power

Britain Coal-Free Week signals a historic shift to clean energy, with zero coal power, increased natural gas and renewables, lower greenhouse gas emissions, and ambitious UK energy policy targeting a 2025 coal phase-out and decarbonization.

 

Key Points

A seven-day period with no coal power in the UK, signaling cleaner energy and progress on emission reductions.

✅ Seven days of zero coal generation in the UK

✅ Natural gas and renewables dominated the electricity mix

✅ Coal phase-out targeted by 2025; emissions cuts planned

 

For the first time in a century, Britain weaned itself off of coal consumption for an entire week, a coal-free power record for the country.

Reuters reported that Britain went seven days without relying on any power generated by coal-powered stations as the share of coal in the grid continued to hit record lows.

The accomplishment is symbolic of a shift to more clean energy sources, with wind surpassing coal in 2016 and the UK leading the G20 in wind share as of recent years; Britain was home to the first coal-powered plant back in the 1880s.

Today, Britain has some aggressive plans in place to completely eliminate its coal power generation permanently by 2025, with a plan to end coal power underway. In addition, Britain aims to cut its total greenhouse gas emissions by 80 percent from 1990 levels within the next 30 years.

Natural gas was the largest source of power for Britain in 2018, providing 39 percent of the nation's total electricity, as the Great Britain generation dashboard shows. Coal contributed only about 5 percent, though low-carbon generation stalled in 2019 according to reports. Burning natural gas also produces greenhouse gases, but it is much more efficient and greener than coal.

In the U.S., 63.5 percent of electricity generated in 2018 came from fossil fuels. About 35.1 percent was produced from natural gas and 27.4 percent came from coal. In addition, 19.3 percent of electricity came from nuclear power and 17.1 percent came from renewable energy sources, according to the U.S. Energy Information Administration.
