History tells us Thomas Edison never visited Pembroke. If he did, we would have remembered.

He is often, incorrectly, credited with inventing the light bulb. It had been around for a while, but the prolific American inventor and businessman devised the incandescent electric light, making the light bulb safe and economical.

The public saw Edison's invention for the first time in December, 1879 when he lit up his Menlo Park, New Jersey laboratory with electric lights. Gas and electric carbon-arc technology followed. Then on Sept. 4, 1882, the first commercial power station went into operation on Pearl Street in New York City's Lower Manhattan. Edison's station served 59 customers paying 24 cents per kilowatt hour. Enter into the development of electric lighting, the Town of Pembroke. Enter, one W. B. McAllister.

McAllister was a prominent businessman and one of Pembroke's original entrepreneurs. A lumberman, McAllister had installed on the Muskrat River a small electric generation station to power his grist mill (it was situated opposite the present-day city hall). This would position Pembroke at the forefront of electric lighting in Canada.

Thus, enter Thomas Ahearn, the man often called the "Canadian Thomas Edison." In 1877, Ahearn had devised a rudimentary telephone system based on Alexander Graham Bell's technology. Using two homemade cigar boxes, magnets and wire, he made Ottawa's first long-distance telephone call, using telegraph wires running through Pembroke. This inventive mind could have been sued by Bell, but he was instead hired to run the Ottawa office of the Bell Telegraphone Company.

This didn't curb Ahearn's appetite to advance communications technology. In 1881, he founded an electrical company with Warren Soper and became the representative for the Westinghouse Company of Chicago. Contracted by Bell, the partners proceeded to build long-distance lines to Montreal, Quebec City and Pembroke. Ahern, a former telegraph operator for J. R. Booth, seemed to have a fondness for the upper Ottawa Valley. Perhaps this is why he chose Pembroke as one of the locations for his first venture into commercial lighting. Contrary to popular belief, the enterprise had installed lamps in commerical establishments as well as on some street corners.

The lights were turned on for the first time on the night of Oct. 8, 1884. Here's how the Pembroke Observer described it: "Electric lamps have been put into nine or 10 of the stores in town, and Wednesday evening they were illuminated by the electric light. The improvement is very marked. A few of the brilliant lights also illuminate our streets now, and there is considerable discussion going on as to where the street lamps should be located.

Compared with buildings illuminated with electric light, those illuminated with coal oil are dark indeed. This new light is truly wonderful."

A week later, town council inked an agreement with McAllister to power a series of street lights from dusk until 1 a. m. Five lamps - two on the east side of the Pembroke Street Bridge, and three on the west side - were installed and operated for $600 a year. The introduction of this new technology was greeted with some humorous observations by town folk.

"A young lady wants to know if the street lamps have been put up for the purpose of having a crowd of young men stand in their neighbourhood and gaze at the passers-by," exclaimed one news reporter. "She says it is perfectly lovely to take a walk with her beau in the brilliant light, but the lamp post starers mar the pleasure considerably. She will probably soon become accustomed to this state of affairs."

This didn't deter the popularity of the new invention. They say the lamp in the waiting room of the Copeland House was so strong that it illuminated the street in front of the hotel. The English and Methodist churches installed electric lights for their Sunday evening services.

Parishioners crowded the Church of England to see for themselves the electric lamp.

"What must heaven be, when this is so bright?" asked one lady sitting in the pews.

Over at the Methodist Church, the rector was closing his sermon when the lamps suddenly died out. There was brief panic until ushers lit some candles.

Apparently the two carbons used in the lamp had fallen together, extinguishing the bulb.

Night watchmen also found the lamps did not cut through thick fog as well as the coal oil lamps. There were other malfunctions of the light bulbs which gave McAllister pause to rethink the instrumentation: "The arc electric light continues to give entire satisfaction on the streets and in the stores. The incandescent light, however, is found to be took weak, and Mr. W. B. McAllister has decided to send the machine back and procure another arc machine in its stead."

Despite these setbacks, residents were asking for more street lights. McAllister moved the light in the west ward to the corner of Berlin and Renfrew Streets (Berlin is now called Isabella). By November, a month after the historic lighting of Canada's first commercial street lights, the use of electricity for lighting was commonplace.

This prompted the Observer-Standard to boast: "Saturday night our town was the only one on the whole line of the CPR from the Atlantic to the Pacific that is wholly lighted with electricity. Mr. McAllister's enterprise met with a prompt response from the merchants and the corporation, the latter adopting lights for the town hall and the streets. Commercial travellers pronouce Pembroke the best lighted town in Canada."

McAllister's plant was eventually upgraded as demand for the lights soared. It was initially two Weston 70-volt direct current dynamos and the incandescent lights ran in series of six, each taking 100 volts. If one light burned out, then all six failed. Larger machines were installed when residential and street lighting was added to Cecilia, William, McKay, Victoria, Church, Moffat and Hincks streets. In 1889, the Pembroke Electric Light Company was incorporated and additional lights were added to the intersections of Pembroke and Munro streets, and Christie and Mary streets. To light up as large an area as possible, the lamps were hung on brackets at the top of 45-foot poles.

Today, there are a few artifacts from the first street lights on display at the Pembroke Hydro Museum, including an 1884 arc lamp and meter. The museum, at the corner of Pembroke Street West and Frank Nighbor St., is located within the 1930 diesel substation. It should be noted that when the plant was dedicated on Oct. 8, 1930, J. A. Cone was still employed by the company. Cone had worked in McAllister's first plant for his brother, Henry, 43 years previous.

As for Thomas Ahearn, he went on to introduce the first electrically-heated street cars and invented the portable electric stove (and cooked the first meal in history by electric means). He also drove the first electric automobile in Ottawa. In 1927, Ahearn, along with Prime Minister Mackenzie King, made the first transatlantic telephone call from Canada to Britain.

The trio of Ahearn, Soper and McAllister should be remembered for making history in Pembroke with a simple streetlight.

Edison would've been proud.

Sustaining U.S. Nuclear Power And Decarbonization

Existing Nuclear Reactor Lifetime Extension sustains carbon-free electricity, supports deep decarbonization, and advances net zero climate goals by preserving the US nuclear fleet, stabilizing the grid, and complementing advanced reactors.

 

Key Points

Extending licenses keeps carbon-free nuclear online, stabilizes grid, and accelerates decarbonization toward net zero.

✅ Preserves 24/7 carbon-free baseload to meet climate targets

✅ Avoids emissions and replacement costs from premature retirements

✅ Complements advanced reactors; reduces capital and material needs

 

Nuclear power is the single largest source of carbon-free energy in the United States and currently provides nearly 20 percent of the nation’s electrical demand. As a result, many analyses have investigated the potential of future nuclear energy contributions in addressing climate change and investing in carbon-free electricity across the sector. However, few assess the value of existing nuclear power reactors.

Research led by Pacific Northwest National Laboratory (PNNL) Earth scientist Son H. Kim, with the Joint Global Change Research Institute (JGCRI), a partnership between PNNL and the University of Maryland, has added insight to the scarce literature and is the first to evaluate nuclear energy for meeting deep decarbonization goals amid rising credit risks for nuclear power identified by Moody's. Kim sought to answer the question: How much do our existing nuclear reactors contribute to the mission of meeting the country’s climate goals, both now and if their operating licenses were extended?

As the world races to discover solutions for reaching net zero as part of the global energy transition now underway, Kim’s report quantifies the economic value of bringing the existing nuclear fleet into the year 2100. It outlines its significant contributions to limiting global warming.

Plants slated to close by 2050 could be among the most important players in a challenge requiring all available carbon-free technology solutions—emerging and existing—alongside renewable electricity in many regions, the report finds. New nuclear technology also has a part to play, and its contributions could be boosted by driving down construction costs.  

“Even modest reductions in capital costs could bring big climate benefits,” said Kim. “Significant effort has been incorporated into the design of advanced reactors to reduce the use of all materials in general, such as concrete and steel because that directly translates into reduced costs and carbon emissions.”

Nuclear power reactors face an uncertain future, and some utilities face investor pressure to release climate reports as well.
The nuclear power fleet in the United States consists of 93 operating reactors across 28 states. Most of these plants were constructed and deployed between 1970-1990. Half of the fleet has outlived its original operating license lifetime of 40 years. While most reactors have had their licenses renewed for an additional 20 years, and some for another 20, the total number of reactors that will receive a lifetime extension to operate a full 80 years from deployment is uncertain.

Other countries also rely on nuclear energy. In France, for example, nuclear energy provides 70 percent of the country’s power supply. They and other countries must also consider extending the lifetime, retiring, or building new, modern reactors while navigating Canadian climate policy implications for electricity grids. However, the U.S. faces the potential retirement of many reactors in a short period—this could have a far stronger impact than the staggered closures other countries may experience.

“Our existing nuclear power plants are aging, and with their current 60-year lifetimes, nearly all of them will be gone by 2050. It’s ironic. We have a net zero goal to reach by 2050, yet our single largest source of carbon-free electricity is at risk of closure, as seen in New Zealand's electricity transition debates,“ said Kim.

Global use of coal-fired electricity set for biggest fall this year

Global Coal Power Decline 2019 signals a record fall in coal-fired electricity as China plateaus, India dips, and the EU and US accelerate renewables, curbing carbon emissions and advancing the global energy transition.

 

Key Points

A record 2019 drop in global coal power as renewables rise and demand slows across China, India, the EU, and the US.

✅ 3% global fall in coal-fired electricity in 2019.

✅ China plateaus; India declines for first time in decades.

✅ EU and US shift to renewables and gas, cutting emissions.

 

The world’s use of coal-fired electricity is on track for its biggest annual fall on record this year after more than four decades of near-uninterrupted growth that has stoked the global climate crisis.

Data shows that coal-fired electricity is expected to fall by 3% in 2019, or more than the combined coal generation in Germany, Spain and the UK last year and could help stall the world’s rising carbon emissions this year.

The steepest global slump on record is likely to emerge in 2019 as India’s reliance on coal power falls for the first time in at least three decades this year, and China’s coal power demand plateaus, reflecting the broader global energy transition underway.

Both developing nations are using less coal-fired electricity due to slowing economic growth in Asia as well as the rise of cleaner energy alternatives. There is also expected to be unprecedented coal declines across the EU and the US as developed economies turn to clean forms of energy such as low-cost solar power to replace ageing coal plants.

In almost 40 years the world’s annual coal generation has fallen only twice before: in 2009, in the wake of the global financial crisis, and in 2015, following a slowdown in China’s coal plants amid rising levels of deadly air pollution.

The research was undertaken by the Centre for Research on Energy and Clean Air , the Institute for Energy Economics and Financial Analysis and the UK climate thinktank Sandbag.

The researchers found that China’s coal-fired power generation was flatlining, despite an increase in the number of coal plants being built, because they were running at record low rates. China builds the equivalent of one large new coal plant every two weeks, according to the report, but its coal plants run for only 48.6% of the time, compared with a global utilisation rate of 54% on average.

The findings come after a report from Global Energy Monitor found that the number of coal-fired power plants in the world is growing, because China is building new coal plants five times faster than the rest of the world is reducing their coal-fired power capacity.

The report found that in other countries coal-fired power capacity fell by 8GW in the 18 months to June but over the same period China increased its capacity by 42.9GW.

In a paper for the industry journal Carbon Brief, the researchers said: “A 3% reduction in power sector coal use could imply zero growth in global CO2 emissions, if emissions changes in other sectors mirror those during 2018.”

However, the authors of the report have warned that despite the record coal power slump the world’s use of coal remained far too high to meet the climate goals of the Paris agreement, and some countries are still seeing increases, such as Australia’s emissions rise amid increased pollution from electricity and transport.

The US – which is backing out of the Paris agreement – has made the deepest cuts to coal power of any developed country this year by shutting coal plants down in favour of gas power and renewable energy, with utilities such as Duke Energy facing investor pressure to disclose climate plans. By the end of August the US had reduced coal by almost 14% over the year compared with the same months in 2018.

The EU reported a record slump in coal-fired electricity use in the first half of the year of almost a fifth compared with the same months last year. This trend is expected to accelerate over the second half of the year to average a 23% fall over 2019 as a whole. The EU is using less coal power in favour of gas-fired electricity – which can have roughly half the carbon footprint of coal – and renewable energy, helped by policies such as the UK carbon tax that have slashed coal-fired generation.

We will not stay quiet on the escalating climate crisis and we recognise it as the defining issue of our lifetimes. The Guardian will give global heating, wildlife extinction and pollution the urgent attention they demand. Our independence means we can interrogate inaction by those in power. It means Guardian reporting will always be driven by scientific facts, never by commercial or political interests.

We believe that the problems we face on the climate crisis are systemic and that fundamental societal change is needed. We will keep reporting on the efforts of individuals and communities around the world who are fearlessly taking a stand for future generations and the preservation of human life on earth. We want their stories to inspire hope. We will also report back on our own progress as an organisation, as we take important steps to address our impact on the environment.

California Faces Power Outages and Landslides Amid Severe Storm

California Storm Outages and Landslides strain utilities, trigger flooding, road closures, and debris flows, causing widespread power cuts and infrastructure damage as emergency response teams race to restore service, clear slides, and support evacuations.

 

Key Points

California Storm Outages and Landslides are storm-driven power cuts and slope failures disrupting roads and utilities.

✅ Tens of thousands face prolonged power outages across regions

✅ Landslides block highways, damage property, hinder access

✅ Crews restore grids, clear debris, support shelters and evacuees

 

California is grappling with a dual crisis of power outages and landslides following a severe storm that has swept across the state. The latest reports indicate widespread disruptions affecting thousands of residents and significant infrastructure damage. This storm is not only a test of California's emergency response capabilities but also a stark reminder of the increasing vulnerability of the state to extreme weather events, and of the U.S. electric grid in the face of climate stressors.

Storm’s Impact on California

The recent storm, which hit California with unprecedented intensity, has unleashed torrential rain, strong winds, and widespread flooding. These severe weather conditions have overwhelmed the state’s infrastructure, leading to significant power outages that are affecting numerous communities. According to local utilities, tens of thousands of homes and businesses are currently without electricity. The outages have been exacerbated by the combination of heavy rain and gusty winds, which have downed power lines and damaged electrical equipment.

In addition to the power disruptions, the storm has triggered a series of landslides across various regions. The combination of saturated soil and intense rainfall has caused several hillside slopes to give way, leading to road closures and property damage. Emergency services are working around the clock to address the aftermath of these landslides, but access to affected areas remains challenging due to blocked roads and ongoing hazardous conditions.

Emergency Response and Challenges

California’s emergency response teams are on high alert as they coordinate efforts to manage the fallout from the storm. Utility companies are deploying repair crews to restore power as quickly as possible, but the extensive damage to infrastructure means that some areas may be without electricity for several days. The state’s Department of Transportation is also engaged in clearing debris from landslides and repairing damaged roads to ensure that emergency services can reach affected communities.

The response efforts are complicated by the scale of the storm’s impact. With many areas experiencing both power outages and landslides, the logistical challenges are immense. Emergency shelters have been set up to provide temporary refuge for those displaced by the storm, but the capacity is limited, and there are concerns about overcrowding and resource shortages.

Community and Environmental Implications

The storm’s impact on local communities has been profound. Residents are facing not only the immediate challenges of power outages and unsafe road conditions but also longer-term concerns about recovery and rebuilding. Many individuals have been forced to evacuate their homes, and local businesses are struggling to cope with the disruption.

Environmental implications are also significant. The landslides and flooding have caused considerable damage to natural habitats and have raised concerns about water contamination and soil erosion. The impact on the environment could have longer-term consequences for the state’s ecosystems and water supply.

Climate Change and Extreme Weather

This storm underscores a growing concern about the increasing frequency and intensity of extreme weather events linked to climate change. California has been experiencing a rise in severe weather patterns, including intense storms, prolonged droughts, and extreme heat waves that strain the grid. These changes are putting additional strain on the state’s infrastructure and emergency response systems.

Experts have pointed out that while individual storms cannot be directly attributed to climate change, the overall trend towards more extreme weather is consistent with scientific predictions. As such, there is a pressing need for California to invest in infrastructure improvements and resilience measures, and to consider accelerating its carbon-free electricity mandate to better withstand future events.

Looking Ahead

As California deals with the immediate aftermath of this storm, attention will turn to recovery and rebuilding efforts. The state will need to address the damage caused by power outages and landslides while also preparing for future challenges posed by climate change.

In the coming days, the focus will be on restoring power, clearing debris, and providing support to affected communities. Long-term efforts will likely involve reassessing infrastructure vulnerabilities, improving emergency response protocols, and investing in climate resilience measures across the grid.

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.

Warren Buffett-linked company to build $200M wind power farm in Alberta

Rattlesnake Ridge Wind Project delivers 117.6 MW in southeast Alberta for BHE Canada, a Berkshire Hathaway Energy subsidiary, using 28 turbines near Medicine Hat under a long-term PPA, supplying renewable power to 79,000 homes.

 

Key Points

A 117.6 MW Alberta wind farm by BHE Canada supplying 79,000 homes via 28 turbines and a long-term PPA.

✅ 28 turbines near Medicine Hat, 117.6 MW capacity

✅ Long-term PPA with a major Canadian corporate buyer

✅ Developed with RES; no subsidies; competitive pricing

 

A company linked to U.S. investor Warren Buffett says it will break ground on a $200-million, 117.6-megawatt wind farm in southeastern Alberta next year.

In a release, Calgary-based BHE Canada, a subsidiary of Buffett's Berkshire Hathaway Energy, says its Rattlesnake Ridge Wind project will be located southwest of Medicine Hat and will produce enough energy to supply the equivalent of 79,000 homes.

"We felt that it was time to make an investment here in Alberta," said Bill Christensen, vice-president of corporate development for BHE Canada, in an interview with the Calgary Eyeopener.

"The structure of the markets here in Alberta, including frameworks for selling renewable energy, make it so that we can invest, and do it at a profit that works for us, and at a price that works for the off-taker," Christensen explained.

Berkshire Hathaway Energy also owns AltaLink, the regulated transmission company that supplies electricity to more than 85 per cent of the Alberta population.

BHE Canada says an unnamed large Canadian corporate partner has signed a long-term power purchase agreement, similar to RBC's solar purchase arrangements, for the majority of the energy output generated by the 28 turbines at Rattlesnake Ridge.

"If you look at just the raw power price that power is going for in Alberta right now, it's averaged around $55 a megawatt hour, or 5.5 cents a kilowatt hour. And we're selling the wind power to this customer at substantially less than that, reflecting wind power's competitiveness in the market, and there's been no subsidies," Christensen said.

 

Positive energy outlook

Christensen said he sees a good future for Alberta's renewable energy industry, not just in wind but also in solar power growth, particularly in the southeast of the province.

But he says BHE Canada is interested in making investments in traditional energy in Alberta, too, as the province is a powerhouse for both green energy and fossil fuels overall.

"It's not a choice of one or the other. I think there is still opportunity to make investments in oil and gas," he said.

"We're really excited about having this project and hope to be able to make other investments here in Alberta to help support the economy here, amid a broader renewable energy surge across the province."

The project is being developed by U.K.-based Renewable Energy Systems, part of a trend where more energy sources make better projects for developers, which is building two other Alberta wind projects totalling 134.6 MW this year and has 750 MW of renewable energy installed or currently under construction in Canada.

BHE Canada and RES are also looking for power purchase partners for the proposed Forty Mile Wind Farm in southeastern Alberta. They say that with generation capacity of 398.5 MW, it could end up being the largest wind power project in Canada.

New York State to investigate sites for offshore wind projects

NYSERDA Offshore Wind Data initiative funds geophysical and geotechnical surveys, seabed and soil studies on New York's shelf to accelerate siting, optimize foundation design, reduce costs, and advance clean energy deployment.

 

Key Points

State funding to support surveys and soil studies guiding offshore wind siting, design, and cost reduction.

✅ Up to $5.5M for geophysical and geotechnical data collection

✅ Focus on seabed soils, shelf geology, and foundation design inputs

✅ Accelerates siting, reduces risk, and lowers offshore wind costs

 

The New York State Energy Research and Development Authority (NYSERDA) is investing up to $5.5 million for the collection of geophysical and geotechnical data to determine future offshore wind development sites.

The funding is to look at seabed soil and geological data for the preliminary design and installation requirements for future offshore wind projects. Its part of N.Y. Gov. Andrew Cuomos plan to develop 9,000 megawatts of offshore wind energy by 2035.

Todays announcement is another step in Governor Cuomos steadfast march to achieving 9,000 megawatts of offshore wind by 2035, putting New York in a clear national leadership position when it comes to advancing this new industry through large-scale energy projects across the state. The surveys NYSERDA will be funding under this solicitation will expand the offshore wind industrys access to geophysical and geotechnical data that will provide the foundation for future offshore wind development in these areas, and accelerate project development while driving down costs, NYSERDA President and CEO Alicia Barton said.

NYSERDA will select one or more contractors to do the investigations, while recent DOE wind energy awards support complementary research, and develop a model for describing geophysical and geotechnical conditions. NYSERDA will also select a contractor to support project management and host the data that is collected. The submission deadline is Jan. 21, 2020.

Todays announcement builds on the data collected in a Geotechnical and Geophysical Desktop Study also released today, which includes information on the middle continental shelf off the shore of New York and New Jersey, where BOEM lease requests are shaping activity, creating a regional overview of the seafloor and sub-seafloor environment as it relates to offshore wind development.

Strong knowledge of environmental conditions and factors, including seabed soil conditions, are essential for the installation of offshore projects, such as Long Island proposals, but only a limited amount of soil sampling and testing has been undertaken to date.

The collection of geophysical and geotechnical data from areas off of New Yorks Atlantic coast is yet another demonstration of New Yorks leadership promoting the responsible development of offshore wind. The data generated by this initiative will ultimately lead to better projects, lower cost, and enhanced safety. New York is leading the way to a clean energy future, as the state finalizes renewable project contracts that expand capacity, and relying on data collection and sound science to get us there, New York Offshore Wind Alliance Director Joe Martens said.
