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.

How Energy Use Has Evolved Throughout U.S. History

U.S. Energy Transition traces the shift from coal and oil to natural gas, nuclear power, and renewables like wind and solar, driven by efficiency, grid modernization, climate goals, and economic innovation.

 

Key Points

The U.S. Energy Transition is the shift from fossil fuels to cleaner power, driven by tech, policy, and markets.

✅ Shift from coal and oil to gas, nuclear, wind, and solar

✅ Enabled by grid modernization, storage, and efficiency

✅ Aims to cut emissions while ensuring reliability and affordability

 

The evolution of energy use in the United States is a dynamic narrative that reflects technological advancements, economic shifts, environmental awareness, and societal changes over time. From the nation's early reliance on wood and coal to the modern era dominated by oil, natural gas, and renewable sources, the story of energy consumption in the U.S. is a testament to innovation and adaptation.

Early Energy Sources: Wood and Coal

In the early days of U.S. history, energy needs were primarily met through renewable resources such as wood for heating and cooking. As industrialization took hold in the 19th century, coal emerged as a dominant energy source, fueling steam engines and powering factories, railways, and urban growth. The widespread availability of coal spurred economic development and shaped the nation's infrastructure.

The Rise of Petroleum and Natural Gas

The discovery and commercialization of petroleum in the late 19th century transformed the energy landscape once again. Oil quickly became a cornerstone of the U.S. economy, powering transportation, industry, and residential heating, and informing debates about U.S. energy security in policy circles. Concurrently, natural gas emerged as a significant energy source, particularly for heating and electricity generation, as pipelines expanded across the country.

Electricity Revolution

The 20th century witnessed a revolution in electricity generation and consumption, and understanding where electricity comes from helps contextualize how systems evolved. The development of hydroelectric power, spurred by projects like the Hoover Dam and Tennessee Valley Authority, provided clean and renewable energy to millions of Americans. The widespread electrification of rural areas and the proliferation of appliances in homes and businesses transformed daily life and spurred economic growth.

Nuclear Power and Energy Diversification

In the mid-20th century, nuclear power emerged as a promising alternative to fossil fuels, promising abundant energy with minimal greenhouse gas emissions. Despite concerns about safety and waste disposal, nuclear power plants became a significant part of the U.S. energy mix, providing a stable base load of electricity, even as the aging U.S. power grid complicates integration of variable renewables.

Renewable Energy Revolution

In recent decades, the U.S. has seen a growing emphasis on renewable energy sources such as wind, solar, and geothermal power, yet market shocks and high fuel prices alone have not guaranteed a rapid green revolution, prompting broader policy and investment responses. Advances in technology, declining costs, and environmental concerns have driven investments in clean energy infrastructure and policies promoting renewable energy adoption. States like California and Texas lead the nation in wind and solar energy production, demonstrating the feasibility and benefits of transitioning to sustainable energy sources.

The Need for Electricity During the COVID-19 Pandemic

US utilities COVID-19 resilience shows electric utilities maintaining demand stability, reaffirming earnings guidance, and accessing the bond market for low-cost financing, as Dominion, NextEra, and Con Edison manage recession risks.

 

Key Points

It is the sector's capacity to sustain demand, financing access, and guidance despite pandemic recession pressures.

✅ Bond market access locks in low-cost, long-term debt

✅ Stable residential load offsets industrial weakness

✅ Guidance largely reaffirmed by major utilities

 

Dominion Energy (D) expects "incremental residential load" gains, consistent with COVID-19 electricity demand patterns, as a result of COVID-19 fallout. Southern Company CEO Tom Fanning says his company is "nowhere near" a need to review earnings guidance because of a potential recession, in a region where efficiency and demand response can help level electricity demand for years.

Sempra Energy (SRE) has reaffirmed earnings per share guidance for 2020 and 2021, as well timing for the sale of assets in Chile and Peru, and peers such as Duke Energy's renewables plan have reaffirmed capital investments to deliver cleaner energy and economic growth. And Xcel Energy (XEL) says it still "hasn’t seen material impact on its business."

Several electric utilities have demonstrated ability to tap the bond market, in line with utility sector trends in recent years, to lock in low-cost financing, as America moves toward broader electrification, despite ongoing turmoil. Their ranks include Dominion Energy, renewable energy leader NextEra Energy (NEE) and Consolidated Edison (ED), which last week sold $1 billion of 30-year bonds at a coupon rate of just 3.95 percent.

It’s still early days for US COVID-19 fallout. And most electric companies have yet to issue guidance. That’s understandable, since so much is still unknown about the virus and the damage it will ultimately do to human health and the global economy. But so far, the US power industry is showing typical resilience in tough times, as it coordinates closely with federal partners to maintain reliability.

Will it last? We won’t know for certain until there’s a lot more data. NextEra is usually first to report its Q1 earnings reports and detailed guidance. But that’s not expected until April 23. And companies may delay financials further, should the virus and efforts to control it impede collection and analysis of data, and as they address electricity shut-off risks affecting customers.

Scotland’s Wind Farms Generate Enough Electricity to Power Nearly 4.5 Million Homes

Scotland Wind Energy delivered record renewable power as wind turbines and farms generated 9,831,320 MWh in H1 2019, supplying clean electricity for every home twice and supporting northern England, according to WWF data.

 

Key Points

Term for Scotland's wind power output, highlighting 2019 records, clean electricity, and progress on decarbonization.

✅ 9,831,320 MWh generated Jan-Jun 2019 by wind farms

✅ Enough to power 4.47 million homes twice in that period

✅ Advances decarbonization and 2030 renewables, 2050 net-zero goals

 

Wind turbines in Scotland produced enough electricity in the first half of 2019, reflecting periods when wind led the power mix across the UK, to power every home in the country twice over, according to new data by the analytics group WeatherEnergy. The wind farms generated 9,831,320 megawatt-hours between January and June, as the UK set a wind generation record in comparable periods, equal to the total electricity consumption of 4.47 million homes during that same period.

The electricity generated by wind in early 2019 is enough to power all of Scotland’s homes, as well as a large portion of northern England’s, highlighting how wind and solar exceeded nuclear in the UK in recent milestones as well, and events such as record UK output during Storm Malik underscore this capacity.

“These are amazing figures,” Robin Parker, climate and energy policy manager at WWF, which highlighted the new data, said in a statement. “Scotland’s wind energy revolution is clearly continuing to power ahead, as wind became the UK’s main electricity source in a recent first. Up and down the country, we are all benefitting from cleaner energy and so is the climate.”

Scotland currently has a target of generating half its electricity from renewables by 2030, a goal buoyed by milestones like more UK electricity from wind than coal in 2016, and decarbonizing its energy system almost entirely by 2050. Experts say the latest wind energy data shows the country could reach its goal far sooner than originally anticipated, especially with complementary technologies such as tidal power in Scottish waters gaining traction.

Elon Musk could help rebuild Puerto Rico with solar-powered electricity grid

Puerto Rico Tesla Solar Power enables resilient microgrids using batteries, renewable energy, and energy storage to rebuild the hurricane-damaged grid, reduce fossil fuels, cut costs, and accelerate recovery with scalable solar-plus-storage solutions.

 

Key Points

A solar-plus-storage plan using Tesla microgrids and batteries to restore Puerto Rico's cleaner, resilient power.

✅ Microgrids cut diesel reliance and harden critical facilities.

✅ Batteries stabilize the grid and shave peak demand costs.

✅ Scalable solar enables faster, modular disaster recovery.

 

Puerto Rico’s governor Ricardo Rossello has said that he will speak to Elon Musk after the Tesla inventor said his innovative solar and battery systems could be used to restore electricity on the island.

Mr Musk was mentioned in a tweet, referencing an article discussing ways to restore Puerto Rico’s power grid, which was knocked out by Hurricane Maria on September 20.

Restoring the ageing and already-weakened network has proved slow: as of Friday 90 per cent of the island remained without power. The island’s electricity company was declared bankrupt in July.

Mr Musk was asked: “Could @ElonMusk go in and rebuild #PuertoRico’s electricity system with independent solar & battery systems?”

The South African entrepreneur replied: “The Tesla team has done this for many smaller islands around the world, but there is no scalability limit, so it can be done for Puerto Rico too.

“Such a decision would be in the hands of the PR govt, PUC, any commercial stakeholders and, most importantly, the people of PR.”

His suggestion was seized upon by Mr Rossello, who then tweeted: “@ElonMusk Let's talk. Do you want to show the world the power and scalability of your #TeslaTechnologies?

“PR could be that flagship project.”

Mr Musk replied that he was happy to talk.

Restoring power to the battered island is a priority for the government, and improving grid resilience remains critical, with hospitals still running on generators and the 3.5 million people struggling with a lack of refrigeration or air conditioning.

Radios broadcast messages advising people how to keep their insulin cool, and doctors are concerned about people not being able to access dialysis.

And, with its power grid wiped out, the Caribbean island could totally rethink the way it meets its energy needs, drawing on examples like a resilient school microgrid built locally. 

“This is an opportunity to completely transform the way electricity is generated in Puerto Rico and the federal government should support this,” said Judith Enck, the former administrator for the region with the environmental protection agency.

“They need a clean energy renewables plan and not spending hurricane money propping up the old fossil fuel infrastructure.”

Forty-seven per cent of Puerto Rico’s power needs were met by burning oil last year - a very expensive and outdated method of electricity generation. For the US as a whole, petroleum accounted for just 0.3 per cent of all electricity generated in 2016 even as the grid isn’t yet running on 100% renewable energy nationwide.

The majority of the rest of Puerto Rico’s energy came courtesy of coal and natural gas, with renewables, which later faced pandemic-related setbacks, accounting for only two per cent of electricity generation.

“In that time of extreme petroleum prices, the utility was borrowing money and buying oil in order to keep those plants operating,” said Luis Martinez, a lawyer at natural resources defense council and former special aide to the president of Puerto Rico’s environmental quality board.

“That precipitated the bankruptcy that followed. It was in pretty poor shape before the storm. Once the storm got there, it finished the job.”

But Mr Martinez told the website Earther that it might be difficult to secure the financing for rebuilding Puerto Rico with renewables from FEMA (Federal Emergency Management Agency) funds.

“A lot of distribution lines were on wood poles,” he said.

“Concrete would make them more resistant to winds, but that would potentially not be authorized under the use of FEMA funds.

"We’re looking into if some of those requirements can be waived so rebuilding can be more resilient.”

Solar farm the size of 313 football fields to be built at Edmonton airport

Airport City Solar Edmonton will deliver a 120-megawatt, 627-acre photovoltaic, utility-scale renewable energy project at EIA, creating jobs, attracting foreign investment, and supplying clean power to Fortis Alberta and airport distribution systems.

 

Key Points

A 120 MW, 627-acre photovoltaic solar farm at EIA supplying clean power to Fortis Alberta and airport systems.

✅ 120 MW utility-scale project over 627 acres at EIA

✅ Feeds Fortis Alberta and airport distribution networks

✅ Drives jobs, investment, and regional sustainability

 

A European-based company is proposing to build a solar farm bigger than 300 CFL football fields at Edmonton's international airport, aligning with Alberta's red-hot solar growth seen across the province.

Edmonton International Airport and Alpin Sun are working on an agreement that will see the company develop Airport City Solar, a 627-acre, 120-megawatt solar farm that reflects how renewable power developers combine resources for stronger projects on what is now a canola field on the west side of the airport lands.

The solar farm will be the largest at an airport anywhere in the world, EIA said in a news release Tuesday, in a region that also hosts the largest rooftop solar array at a local producer.

"It's a great opportunity to drive economic development as well as be better for the environment," Myron Keehn, vice-president, commercial development and air service at EIA, told CBC News, even as Alberta faces challenges with solar expansion that require careful planning.

"We're really excited that [Alpin Sun] has chosen Edmonton and the airport to do it. It's a great location. We've got lots of land, we're geographically located north, which is great for us, because it allows us to have great hours of sunlight.

"As everyone knows in Edmonton, you can golf early in the morning or golf late at night in the summertime here. And in wintertime it's great, because of the snow, and the reflective [sunlight] off the snow that creates power as well."

Airport official Myron Keehn says the field behind him will become home to the world's largest solar farm at an airport. (Scott Neufeld/CBC)

The project will "create jobs, provide sustainable solar power for our region and show our dedication to sustainability," Tom Ruth, EIA president and CEO, said in the news release, while complementing initiatives by Ermineskin First Nation to expand Indigenous participation in electricity generation.

Construction is expected to begin in early 2022, as new solar facilities in Alberta demonstrate lower costs than natural gas. The solar farm would be operational by the end of that year, the release said. 

Alpin Sun says the project will bring in $169 million in foreign investment to the Edmonton metro region amid federal green electricity contracts that are boosting market certainty. 

Power generated by Airport City Solar will feed into Fortis Alberta and airport distribution systems.
