The blustery weather of the last two days has pushed Ontario's wind-power output into record territory.

As of 9 p.m. October 26, the province hit an all-time high for hourly wind power output, cranking out 1,056 megawatts of electricity.

That is normally the amount of electricity generated by two nuclear reactor units at the Pickering generating station, which produce 515 megawatts at any given time. The province's wind output also trumped its coal-fired electricity output on October 25.

Ontario's wind output is usually negligible, reported CTV Toronto's Paul Bliss.

Environment Canada started the day with wind warnings for most of most of southern Ontario.

The warning for the GTA was lifted at 3:17 p.m. on October 27. At 4 p.m., Environment Canada reported wind speeds of 48 kilometres per hour, with busts to 61 km/h.

The relatively balmy temperature of 19 degrees Celsius meant some Toronto windsurfing enthusiasts hit the water during the afternoon.

Climate change: Greenhouse gas concentrations again break records

Rising Greenhouse Gas Concentrations drive climate change, with CO2, methane, and nitrous oxide surging; WMO data show higher radiative forcing, elevated pre-industrial baselines, and persistent atmospheric concentrations despite Paris Agreement emissions pledges.

 

Key Points

Increasing atmospheric CO2, methane, and nitrous oxide levels that raise radiative forcing and drive warming.

✅ WMO data show CO2 at 407.8 ppm in 2018, above decade average

✅ Methane and nitrous oxide surged, elevating total radiative forcing

✅ Concentrations differ from emissions; sinks absorb about half

 

The World Meteorological Organization (WMO) says the increase in CO2 was just above the average rise recorded over the last decade.

Levels of other warming gases, such as methane and nitrous oxide, have also surged by above average amounts.

Since 1990 there's been an increase of 43% in the warming effect on the climate of long lived greenhouse gases.

The WMO report looks at concentrations of warming gases in the atmosphere rather than just emissions.

The difference between the two is that emissions refer to the amount of gases that go up into the atmosphere from the use of fossil fuels, such as burning coal for coal-fired electricity generation and from deforestation.

Concentrations are what's left in the air after a complex series of interactions between the atmosphere, the oceans, the forests and the land. About a quarter of all carbon emissions are absorbed by the seas, and a similar amount by land and trees, while technologies like carbon capture are being explored to remove CO2.

Using data from monitoring stations in the Arctic and all over the world, researchers say that in 2018 concentrations of CO2 reached 407.8 parts per million (ppm), up from 405.5ppm a year previously.

This increase was above the average for the last 10 years and is 147% of the "pre-industrial" level in 1750.

The WMO also records concentrations of other warming gases, including methane and nitrous oxide, and some countries have reported declines in certain potent gases, as noted in US greenhouse gas controls reports, though global levels remain elevated. About 40% of the methane emitted into the air comes from natural sources, such as wetlands, with 60% from human activities, including cattle farming, rice cultivation and landfill dumps.

Methane is now at 259% of the pre-industrial level and the increase seen over the past year was higher than both the previous annual rate and the average over the past 10 years.

Nitrous oxide is emitted from natural and human sources, including from the oceans and from fertiliser-use in farming. According to the WMO, it is now at 123% of the levels that existed in 1750.

Last year's increase in concentrations of the gas, which can also harm the ozone layer, was bigger than the previous 12 months and higher than the average of the past decade.

What concerns scientists is the overall warming impact of all these increasing concentrations. Known as total radiative forcing, this effect has increased by 43% since 1990, and is not showing any indication of stopping.

There is no sign of a slowdown, let alone a decline, in greenhouse gases concentration in the atmosphere despite all the commitments under the Paris agreement on climate change and the ongoing global energy transition efforts," said WMO Secretary-General Petteri Taalas.

"We need to translate the commitments into action and increase the level of ambition for the sake of the future welfare of mankind," he added.

"It is worth recalling that the last time the Earth experienced a comparable concentration of CO2 was three to five million years ago. Back then, the temperature was 2-3C warmer, sea level was 10-20m higher than now," said Mr Taalas.

The UN Environment Programme will report shortly on the gap between what actions countries are taking to cut carbon, for example where Australia's emissions rose 2% recently, and what needs to be done to keep under the temperature targets agreed in the Paris climate pact.

Preliminary findings from this study, published during the UN Secretary General's special climate summit last September, indicated that emissions continued to rise during 2018, although global emissions flatlined in 2019 according to the IEA.

Both reports will help inform delegates from almost 200 countries who will meet in Madrid next week for COP25, following COP24 in Katowice the previous year, the annual round of international climate talks.

City officials take clean energy message to Georgia Power, PSC

Georgia Cities Clean Energy IRP Coalition unites Savannah, Atlanta, Decatur, and Athens-Clarke to shape Georgia Power's Integrated Resource Plan, accelerating renewables, energy efficiency, community solar, and coal retirements through Georgia Public Service Commission hearings.

 

Key Points

Georgia cities working to steer Georgia Power's IRP toward renewables, energy efficiency, and community solar.

✅ Targets coal retirements and doubling renewables by 2035

✅ Advocates data access, transparency, and energy efficiency

✅ Seeks affordable community solar options for low-income customers

 

Savannah is among several Georgia cities that have led the charge forward in recent years to push for clean energy. Now, several of the state's largest municipalities are banding together to demand action from Georgia's largest energy provider.

Hearings regarding Georgia Power's Integrated Resource Plan (IRP) happen every three years, but this year for the first time the cities of Savannah, Decatur, Atlanta and Athens-Clarke and DeKalb counties were at the table.

"It's pretty unprecedented. It's such an important opportunity to get to represent ourselves and our citizens," said City of Savannah Energy Analyst Alicia Brown, the Savannah representative for the Georgia Coalition for Local Governments.

The IRP, which essentially maps out how the company will use its various forms of energy over the next 20 years was filed with the Georgia Public Service Commission (GPSC) in January, the 200-page IRP outlines Georgia Power's plans to shutter nearly all Georgia Power-controlled coal units, similar to Tucson Electric Power's coal exit timelines elsewhere, which could begin later this year.

The company is also planning to double its renewable energy generation by 2035. The IRP also outlines plans for several programs, including an Income-Qualified Community Solar Pilot, reflecting momentum for community energy programs in other states as well.

During the hearings the coalition, alongside the other groups, had the ability to question Georgia Power officials about the plan to include the proposed increase per kilowatt for the company's Simple Solar program, Behind-the-Meter Solar program study and various other components, amid debates over solar strategy in the South that could impact lower income customers.

"The established and open IRP process is central to effective, long-term energy planning in Georgia and is part of our commitment to 2.7 million customers to deliver clean, safe, reliable and affordable energy. In continuing our longstanding relationship with the City of Savannah, we welcome their interest and participation in the IRP process," John Kraft, Georgia Power spokesman said in an email.

Brown said the coalition's areas of interest fall into three categories: energy efficiency and demand response, data access and transparency and renewable energy for citizens as well as the governments in the coalition.

"We have these renewable goals and just the way the current regulations are set, the way the current laws are on the books, and developments like consumer choice in California show how policy shifts can reshape utility markets, it's very challenging for us to meet those renewable energy goals without Georgia Power setting up programs that are workable for us," she said.

The city of Savannah is already taking action locally to reduce carbon emissions and move toward clean and renewable energy through the 100% Savannah Clean Energy Plan, which was adopted by Savannah City Council in December.

The plan aims to achieve 100% renewable electricity community-wide by 2035 and 100% renewable energy for all energy needs by 2050.

Council previously approved the 100% Clean Energy Resolution needed to develop the plan in March 2020, making Savannah the fifth city in the state to pledge to pursue a lower carbon future to fight climate change.

The final plan includes 45 strategies that fall into five categories: energy efficiency; renewable energy; transportation and mobility; community and economic development; and education and engagement.

Brown said the education and engagement component is central to the plan, but the pandemic has hindered community education and awareness efforts, and utilities have warned customers about pandemic-related scams that complicate outreach, something the city hopes to catapult in the coming weeks.

"With the 100% Savannah resolution passing right before the pandemic, we haven't had as many opportunities to raise awareness about the initiative and to educate the public about clean energy as we would like. This transition will present a lot of opportunities for our communities, but only if people know that they are there to be taken," she said.

"... We also want to engage the community so that they feel like they are developing this vision for a healthy, prosperous, clean community alongside us. It's not just us telling them, 'we're going to have a clean energy future and it's going to look like this,' but really helping them to develop and realize a collective vision for what 100% Savannah should be."

The final round of IRP hearings are scheduled for next month. Those hearings will allow the coalition and other groups to put witnesses on the stand who will make the case for why Georgia Power's IRP should be different, Brown said.

In June, Georgia Power, following a June bill reduction for customers, will have a chance to offer rebuttal testimony and will again be subject to cross examination. Shortly after those hearings, the parties will join together for the settlement process, a sort of compromise on the plan that the commission will vote on toward the beginning of July.

Heathrow Airport Power Outage: Vulnerabilities Flagged Days Before Disruption

Heathrow Airport Power Outage 2025 disrupted operations with mass flight cancellations and diversions after a grid failure, exposing infrastructure resilience gaps, crisis management flaws, and raising passenger compensation and safety oversight concerns.

 

Key Points

A grid failure closed Heathrow, causing mass cancellations and diversions, exposing resilience and communication lapses.

✅ Grid fire triggered airport-wide shutdown

✅ 1,400+ flights canceled or diverted

✅ Inquiry probes resilience, communication, compensation

 

On March 21, 2025, Heathrow Airport, Europe's busiest, suffered a catastrophic power outage, similar to another high-profile outage seen at major events, that led to the cancellation and diversion of over 1,400 flights, affecting nearly 300,000 passengers and costing airlines an estimated £100 million. The power failure, triggered by a fire at an electricity substation in west London, left Heathrow with a significant operational crisis. This disruption is even more significant considering that Heathrow is one of the most expensive airports globally, which raises concerns about its infrastructure resilience and broader electricity system resilience across Europe.

In a parliamentary committee meeting, Heathrow officials admitted that vulnerabilities in the airport’s power supply were flagged just days before the outage. Nigel Wicking, Chief Executive of the Heathrow Airline Operators' Committee (HAOC), informed MPs that concerns regarding power resilience had been raised on March 15, following disruptions caused by cable thefts impacting runway lights. Despite these warnings, the airport’s management did not address the vulnerabilities urgently, even as UK net zero policies continue to reshape infrastructure planning, which ultimately led to the disastrous outage.

The airport was closed for a day, with serious consequences for not only airlines but also the surrounding community and businesses. British Airways alone faced millions of pounds in losses, and passengers experienced significant emotional distress, missing vital life events like weddings and funerals due to flight cancellations. The committee is now questioning officials from National Grid and Scottish and Southern Electricity Networks to better understand why Heathrow’s infrastructure failed, in the context of a cleaner grid following the British carbon tax that reduced coal use, how it communicated with affected parties, and what measures will be taken to compensate impacted passengers.

Heathrow’s Chief Executive, Thomas Woldbye, defended the closure decision, stating it would have been disastrous to keep the airport open under such circumstances. He noted that continuing operations would have left tens of thousands of passengers stranded and would have posed safety risks due to the failure of fire surveillance and CCTV systems. However, Wicking, representing the airlines, pointed out that Heathrow’s lack of resilience was unacceptable given the amount spent on the airport, emphasizing the need for better infrastructure, including addressing SF6 in switchgear during upgrades, and more transparent management practices.

Looking forward, the MPs intend to investigate the airport’s emergency preparedness, why the resilience review from 2018 wasn’t shared with airlines, and whether enough preventative measures were in place amid surging data demand that could strain electricity supplies. The outcome of this inquiry could have lasting effects on how Heathrow and other major airports handle their infrastructure and crisis management systems, as drought-driven hydro challenges demonstrate the wider climate stresses on power networks.

Ontario to Provide New and Expanded Energy-Efficiency Programs

Ontario CDM Programs expand energy efficiency, demand response, and DER incentives via IESO's Save on Energy, cutting peak demand, lowering bills, and supporting electrification, retrofits, and LED lighting to meet Ontario's growing electricity needs.

 

Key Points

Ontario CDM Programs are IESO incentives that cut peak demand and energy use via demand response, retrofits and DERs.

✅ Delivered by IESO's Save on Energy to reduce peak demand

✅ Incentives for demand response, retrofits, LEDs, and DER solutions

✅ Help homes, businesses, and greenhouses lower bills and emissions

 

Ontario will be making available four new and expanded energy-efficiency programs, also known as Conservation and Demand Management (CDM) programs, to ensure a reliable, affordable, and clean electricity system, including ultra-low overnight pricing options to power the province, drive electrification and support strong economic growth. As there will be a need for additional electricity capacity in Ontario beginning in 2025, and continuing through the decade, CDM programs are among the fastest and most cost-effective ways of meeting electricity system needs.

 

Conservation and Demand Management

The Ontario government launched the 2021-2024 CDM Framework on January 1, 2021. The framework focuses on cost-effectively meeting the needs of Ontario’s electricity system, including by focusing on the achievement of provincial peak demand reductions and initiatives such as extended off-peak electricity rates, as well as on targeted approaches to address regional and/or local electricity system needs.

CDM programs are delivered by the Independent Electricity System Operator (IESO), which implemented staff lockdown measures during COVID-19, through the Save on Energy brand. These programs address electricity system needs and help consumers reduce their electricity consumption to lower their bills. CDM programs and incentives are available for homeowners, small businesses, large businesses, and contractors, and First Nations communities.

 

New and Expanded Programs

The four new and expanded CDM programs will include:

A new Residential Demand Response Program for homes with existing central air conditioning and smart thermostats to help deliver peak demand reductions. Households who meet the criteria could voluntarily enroll in this program and, alongside protections like disconnection moratoriums for residential customers, be paid an incentive in return for the IESO being able to reduce their cooling load on a select number of summer afternoons to reduce peak demand. There are an estimated 600,000 smart thermostats installed in Ontario.
Targeted support for greenhouses in Southwest Ontario, including incentives to install LED lighting, non-lighting measures or behind-the-meter distributed energy resources (DER), such as combined solar generation and battery storage.
Enhancements to the Save On Energy Retrofit Program for business, municipalities, institutional and industrial consumers to include custom energy-efficiency projects. Examples of potential projects could include chiller and other HVAC upgrades for a local arena, building automation and air handling systems for a hospital, or building envelope upgrades for a local business.
Enhancements to the Local Initiatives Program to reduce barriers to participation and to add flexibility for incentives for DER solutions.
It is the government’s intention that the new and expanded CDM programs will be available to eligible electricity customers beginning in Spring 2023.

The IESO estimates that the new program offers will deliver total provincial peak electricity demand savings of 285 megawatts (MW) and annual energy savings of 1.1 terawatt hours (TWh) by 2025, reflecting pandemic-era electricity usage shifts across Ontario. Savings will persist beyond 2025 with a total reduction in system costs by approximately $650 million over the lifetime of the measures, and will support economic recovery, as seen with electricity relief during COVID-19 measures, decarbonization and energy cost management for homes and businesses.

These enhancements will have a particular impact in Southwest Ontario, with regional peak demand savings of 225 MW, helping to alleviate electricity system constraints in the region and foster economic development, supported by stable electricity pricing for industrial and commercial companies in Ontario.

The overall savings from this CDM programming will result in an estimated three million tonnes of greenhouse gas emissions reductions over the lifetime of the energy-efficiency measures to help achieve Ontario’s climate targets and protect the environment for the future.

The IESO will be updating the CDM Framework Program Plan, which provides a detailed breakdown of program budgets and energy savings and peak demand targets expected to be achieved.

China power cuts: What is causing the country's blackouts?

China Energy Crisis drives electricity shortages, power cuts, and blackouts as coal prices surge, carbon-neutrality rules tighten, and manufacturing hubs ration energy, disrupting supply chains and industrial output ahead of winter demand peaks.

 

Key Points

A power shortfall from costly coal, price caps, and emissions targets, causing blackouts and industrial rationing.

✅ Coal prices soar while electricity tariffs are capped

✅ Factories in northeast hubs face rationing and downtime

✅ Supply chains risk delays ahead of winter demand

 

China is struggling with a severe shortage of electricity which has left millions of homes and businesses hit by power cuts.

Blackouts are not that unusual in the country but this year a number of factors have contributed to a perfect storm for electricity suppliers, including surging electricity demand globally.

The problem is particularly serious in China's north eastern industrial hubs as winter approaches - and is something that could have implications for the rest of the world.

Why has China been hit by power shortages?
The country has in the past struggled to balance electricity supplies with demand, which has often left many of China's provinces at risk of power outages.

During times of peak power consumption in the summer and winter the problem becomes particularly acute.

But this year a number of factors have come together to make the issue especially serious.

As the world starts to reopen after the pandemic, demand for Chinese goods is surging and the factories making them need a lot more power, highlighting China's electricity appetite in recent months.

Rules imposed by Beijing as it attempts to make the country carbon neutral by 2060 have seen coal production slow, even as the country still relies on coal for more than half of its power and as low-emissions generation is set to cover most global demand growth.

And as electricity demand has risen, the price of coal has been pushed up.

But with the government strictly controlling electricity prices, coal-fired power plants are unwilling to operate at a loss, with many drastically reducing their output instead.

Who is being affected by the blackouts?
Homes and businesses have been affected by power cuts as electricity has been rationed in several provinces and regions.

A coal-burning power plant can be seen behind a factory in China"s Inner Mongolia Autonomous Region

The state-run Global Times newspaper said there had been outages in four provinces - Guangdong in the south and Heilongjiang, Jilin and Liaoning in the north east. There are also reports of power cuts in other parts of the country.

Companies in major manufacturing areas have been called on to reduce energy usage during periods of peak demand or limit the number of days that they operate.

Energy-intensive industries such as steel-making, aluminium smelting, cement manufacturing and fertiliser production are among the businesses hardest hit by the outages.

What has the impact been on China's economy?
Official figures have shown that in September 2021, Chinese factory activity shrunk to the lowest it had been since February 2020, when power demand dropped as coronavirus lockdowns crippled the economy.

Concerns over the power cuts have contributed to global investment banks cutting their forecasts for the country's economic growth.

Goldman Sachs has estimated that as much as 44% of the country's industrial activity has been affected by power shortages. It now expects the world's second largest economy to expand by 7.8% this year, down from its previous prediction of 8.2%.

Globally, the outages could affect supply chains, including solar supply chains as the end-of-the-year shopping season approaches.

Since economies have reopened, retailers around the world have already been facing widespread disruption amid a surge in demand for imports.

China's economic planner, the National Development and Reform Commission (NDRC), has outlined a number of measures to resolve the problem, with energy supplies in the northeast of the country as its main priority this winter.

The measures include working closely with generating firms to increase output, ensuring full supplies of coal and promoting the rationing of electricity.

The China Electricity Council, which represents generating firms, has also said that coal-fired power companies were now "expanding their procurement channels at any cost" in order to guarantee winter heat and electricity supplies.

However, finding new sources of coal imports may not be straightforward.

Russia is already focused on its customers in Europe, Indonesian output has been hit by heavy rains and nearby Mongolia is facing a shortage of road haulage capacity,

Are energy shortages around the world connected?
Power cuts in China, UK petrol stations running out of fuel, energy bills jumping in Europe, near-blackouts in Japan and soaring crude oil, natural gas and coal prices on wholesale markets - it would be tempting to assume the world is suddenly in the grip of a global energy drought.

However, it is not quite as simple as that - there are some distinctly different issues around the world.

For example, in the UK petrol stations have run dry as motorists rushed to fill up their vehicles over concerns that a shortage of tanker drivers would mean fuel would soon become scarce.

Meanwhile, mainland Europe's rising energy bills and record electricity prices are due to a number of local factors, including low stockpiles of natural gas, weak output from the region's windmills and solar farms and maintenance work that has put generating operations out of action.

Failed PG&E power line blamed for Drum fire off Hwy 246 last June

PG&E Drum Fire Cause identified as a power line failure in Santa Barbara County, with arcing electricity igniting vegetation near Buellton on Drum Canyon Road; 696 acres burned as investigators and CPUC review PG&E safety.

 

Key Points

A failed PG&E power line sparked the 696-acre Drum Fire near Buellton; the utility is conducting its own probe.

✅ Power line failed between poles, arcing ignited vegetation.

✅ 696 acres burned; no structures damaged or injuries.

✅ PG&E filed CPUC incident report; ongoing investigation.

 

A downed Pacific Gas and Electric Co. power line was the cause of the Drum fire that broke out June 14 on Drum Canyon Road northwest of Buellton, a reminder that a transformer explosion can also spark multiple fires, the Santa Barbara County Fire Department announced Thursday.

The fire broke out about 12:50 p.m. north of Highway 246 and burned about 696 acres of wildland before firefighters brought it under control, although no structures were damaged or mass outages like the Los Angeles power outage occurred, according to an incident summary.

A team of investigators pinpointed the official cause as a power line that failed between two utility poles and fell to the ground, and as downed line safety tips emphasize, arcing electricity ignited the surrounding vegetation, said County Fire Department spokesman Capt. Daniel Bertucelli.

In response, a PG&E spokesman said the utility is conducting its own investigation and does not have access to whatever data investigators used, and, as the ATCO regulatory penalty illustrates, such matters can draw significant oversight, but he noted the company filed an electric incident report on the wire with the California Public Utilities Commission on June 14.

"We are grateful to the first responders who fought the 2020 Drum fire in Santa Barbara County and helped make sure that there were no injuries or fatalities, outcomes not always seen in copper theft incidents, and no reports of structures damaged or burned," PG&E spokesman Mark Mesesan said.

"While we are continuing to conduct our own investigation into the events that led to the Drum fire, and as the Site C watchdog inquiry shows, oversight bodies can seek more transparency, PG&E does not have access to the Santa Barbara County Fire Department's report."

He said PG&E remains focused on reducing wildfire risk across its service area while limiting the scope and duration of public safety power shutoffs, including strategies like line-burying decisions adopted by other utilities, and that the safety of customers and communities it serves are its most important responsibility.
