Forget the Pickering nuclear plant – you could soon be running your fridge on electricity supplied from your kids' school around the corner.

As the first step in an ambitious plan to create a green grid from the rooftops of schools across the city, the Toronto District School Board will spend the summer devising a renewable energy plan involving all 558 of its school sites.

If everything goes smoothly, windmills and solar panels will cover the roofs of 10 schools across the city as early as next summer.

"Because schools are so strategically located throughout the city, we could create a perfect green grid," said Josh Matlow, a board trustee and a driving force behind the idea.

The Ontario government announced a $250,000 grant for the first steps of the project.

The board – through a consultant – will examine everything from solar panels and solar thermal water heaters to ground source heating, said Sheila Penny, executive officer for facility services. It will have to decide whether to build and operate those systems or lease the space to renewable electricity companies. And then there's the question of using that electricity to power the schools themselves, or to sell it to the provincial power grid – a proposal that could earn the cash-strapped board big money in the long term, as electricity generated from solar panels pays a hefty 42 cents per kilowatt-hour. (By comparison, Toronto Hydro charges 5.5 cents per kilowatt-hour, plus transmission and other charges.)

Every project will become part of the school's environment curriculum, Matlow said.

"The physical presence of solar panels on the school roof would be a constant reminder," he said. "You are instantly aware that energy comes from somewhere and you need to be responsible for it."

William Lyon Mackenzie Collegiate has a jump-start on the project. Led by 70 students, the school has already solicited proposals for solar panels to cover "every single square foot" of its roof, said David Godri, 18, the student who proposed the idea last summer. The company chosen will lease space from the school board.

"We have all these roofs that aren't being used," he said. "(The board is) losing money in the long run because they're waiting too long."

The student group, called SWITCH – Solar and Wind Initiatives Towards Change – has built four windmills they'll mount on the school roof this summer, he said.

Eco-school champion Cindy English said she hopes the board decides to generate electricity for their own use rather than selling it.

"When there was the big blackout in Toronto, it would have been nice to have alternative energy," said English, who planted a natural garden at Maurice Cody Public School, her children's elementary school.

"In Ontario, we have such an addiction to coal and nuclear. It's terrific the school board is trying to get away from that," said James Gibbons, a North Toronto Collegiate student who presented the board with a plan to shut down 60,000 school computers at night and in summers, saving $2.4 million annually. "Solar power is such an exciting option. On the hottest days, when the air conditions are driving up electricity demand, that's when solar panels produce the most electricity."

Wind Denmark - summer's autumn weather provides extraordinarily low electricity prices

Western Denmark Negative Electricity Prices stem from wind energy oversupply, grid congestion, and limited interconnector capacity via Nord Pool and TenneT, underscoring electrification needs, renewable integration, special regulation, and system flexibility.

 

Key Points

They are sub-zero power prices from wind oversupply, weak interconnectors, low demand, and balancing needs.

✅ Caused by high wind output, low demand, and export bottlenecks

✅ Limited Nord Pool interconnector capacity depresses prices

✅ Special regulation and district heating absorb excess power

 

A downturn in the cable connection to Norway and Sweden, together with low electricity consumption and high electricity production, has pushed down European electricity prices to a negative level in Western Denmark.

A sign that the electrification of society is urgently needed, says Soren Klinge, head of electricity market at Wind Denmark today.

The heavy winds during the first weekend of July, unlike periods when cheap wind power wanes in the UK, have not only had consequences for the Danes who had otherwise been looking forward to spending their first days at home in the garden or at the beach. It has also pushed down prices in the electricity market to a negative level, which especially the West Danish wind turbine owners have had to notice.

'The electricity market is currently affected by an unfortunate coincidence of various factors that have a negative impact on the electricity price: a reduced export capacity to the other Nordic countries, a low electricity consumption and a high electricity generation, reflecting broader concerns over dispatchable power shortages in Europe today. Unfortunately, the coincidence of these three factors means that the price base falls completely out of the market. This is another sign that the electrification of society is urgently needed, 'explains Soren Klinge, electricity market manager at Wind Denmark.

According to the European power exchange Nord Pool Spot, where UK peak power prices are also tracked, the cable connection to Sweden is expected to return to full capacity from 19 July. The connection between Jutland and Norway is only expected to return to full capacity in early September.

2000 MWh / hour in special regulation

During the windy weather on Monday morning, July 6, up to 2000 MWh / hour was activated at national level in the form of so-called special regulation. Special regulation is the designation that the German system operator TenneT switches off Danish electricity generation at cogeneration plants and wind turbines in order to help with the balancing of the German power system during such events. In addition, electric boilers at the cogeneration plants also contribute by using the electricity from the electricity grid and converting it to district heating for the benefit of Danish homes and businesses.

'The Danish wind turbines are probably the source of most of the special regulation, because there are very few cogeneration units to down-regulate electricity generation. Of course, it is positive to see that we have a high degree of flexibility in the wind-based power system at home. That being said, Denmark does not really get ahead with the green transition, even as its largest energy company plans to stop using coal by 2023, until we are able to raise electricity consumption based on renewable energy.

U.S. Electricity and natural gas prices explained

Energy Pricing Factors span electricity generation, transmission, and distribution costs, plus natural gas supply-demand, renewables, seasonal peaks, and wholesale pricing effects across residential, commercial, and industrial customers, usage patterns, weather, and grid constraints.

 

Key Points

They are the costs and market forces driving electricity and natural gas prices, from generation to delivery and demand.

✅ Generation, transmission, distribution shape electricity rates

✅ Gas prices hinge on supply, storage, imports/exports

✅ Demand shifts: weather, economy, and fuel alternatives

 

There are a lot of factors that affect energy prices globally. What’s included in the price to heat homes and supply them with electricity may be a lot more than some people may think.

Electricity
Generating electricity is the largest component of its price, according to the U.S. Energy Information Administration (EIA). Generation accounts for 56% of the price of electricity, while distribution and transmission account for 31% and 13% respectively.

Homeowners and businesses pay more for electricity than industrial companies, and U.S. electricity prices have recently surged, highlighting broader inflationary pressures. This is because industrial companies can take electricity at higher voltages, reducing transmission costs for energy companies.

“Industrial consumers use more electricity and can receive it at higher voltages, so supplying electricity to these customers is more efficient and less expensive. The price of electricity to industrial customers is generally close to the wholesale price of electricity,” EIA explains.

NYSEG said based on the average use of 600 kilowatt-hours per month, its customers spent the most money on delivery and transition charges in 2020, 57% or about $42, and residential electricity bills increased 5% in 2022 after inflation, according to national data. They also spent on average 35% (~$26) on supply charges and 8% (~$6) on surcharges.

Electricity prices are usually higher in the summer. Why? Because energy companies use sources of electricity that cost more money. It used to be that renewable sources, like solar and wind, were the most expensive sources of energy but increased technological advances have changed this, according to the International Energy Agency’s 2021 World Energy Outlook.

“In most markets, solar PV or wind now represents the cheapest available source of new electricity generation. Clean energy technology is becoming a major new area for investment and employment – and a dynamic arena for international collaboration and competition,” the report said.

Natural gas
The price of natural gas is driven by supply and demand. If there is more supply, prices are generally lower. If there is not as much supply, prices are generally higher the EIA explains. On the other side of the equation, more demand can also increase the price and less demand can decrease the price.

High natural gas prices mean people turn their home thermostats down a few degrees to save money, so the EIA said reduced demand can encourage companies to produce more natural gas, which would in turn help lower the cost. Lower prices will sometimes cause companies to reduce their production, therefore causing the price to rise.

The three major supply factors that affect prices: the amount of natural gas produced, how much is stored, and the volume of gas imported and exported. The three major demand factors that affect price are: changes in winter/summer weather, economic growth, and the broader energy crisis dynamics, as well as how much other fuels are available and their price, said EIA.

To think the price of natural gas is higher when the economy is thriving may sound counterintuitive but that’s exactly what happens. The EIA said this is because of increases in demand.

While the summer of 2019 set records for heat and brought severe storms, ComEd customers stayed cool thanks to record-setting reliability during the season. These smart grid investments over the last seven years helped to set records in key reliability measurements, including frequency of outages metrics, and through smart switches that reroute power around potential problem areas, avoided more than 538,000 customer interruptions from June to August.

"In a summer where we were challenged by extreme weather, we saw our smart grid investments and our people continue to deliver the highest levels of reliability, backed by extensive disaster planning across utilities, for the families and businesses we serve," said Joe Dominguez, CEO of ComEd. "We're proud to deliver the most affordable, cleanest and, as we demonstrated this summer, most reliable energy to our customers. I want to thank our 6,000 employees who work around the clock in often challenging conditions to power our communities."

ComEd has avoided more than 13 million customer interruptions since 2012, due in part to smart grid and system improvements. The avoided outages have resulted in $2.4 billion in estimated savings to society. In addition to keeping energy flowing for residents, strong power reliability continues to help persuade industrial and commercial companies to expand in northern Illinois and Chicago. The GridWise Alliance recently recognized Illinois as the No. 2 state in the nation for its smart grid implementation.

"Our smart grid investments has vastly improved the infrastructure of our system," said Terry Donnelly, ComEd president and chief operating officer. "We review the system and our operations continually to make sure we're investing in areas that benefit the greatest number of customers, and to prepare for public-health emergencies as well. On a daily basis and during storms or to reduce wildfire risk when necessary, our customers are seeing fewer and fewer interruptions to their lives and businesses."

ComEd customers also set records for energy savings this summer. Through its Peak Time Savings program and other energy-efficiency programs offered by utilities, ComEd empowered nearly 300,000 families and individuals to lower their bills by a total of more than $4 million this summer for voluntarily reducing their energy use during times of peak demand. Since the Peak Time Savings program launched in 2015, participating customers have earned a total of more than $10 million in bill credits.

Europe's EV Slump Sounds Alarm for Climate Goals

Europe EV Sales Slowdown signals waning incentives, economic uncertainty, and supply chain constraints, threatening climate targets and net-zero emissions goals while highlighting the need for charging infrastructure, affordable batteries, and policy support across key markets.

 

Key Points

Europe's early-2024 EV registrations fell as incentives waned and supply gaps persisted, putting climate targets at risk.

✅ Fewer subsidies and tax breaks cut EV affordability

✅ Inflation and recession fears dampen car purchases

✅ Supply-chain and lithium constraints limit availability

 

A recent slowdown in Europe's electric vehicle (EV) sales raises serious concerns about the region's ability to achieve its ambitious climate targets.  After years of steady growth, new EV registrations declined in key markets like Norway, Germany, and the U.K. in early 2024. Experts are warning that this slump jeopardizes the transition away from fossil fuels and could undermine Europe's commitment to a net-zero emissions future.

 

Factors Behind the Decline

Several factors are contributing to the slowdown in EV sales:

  • Reduced Incentives: Many European countries have scaled back generous subsidies and tax breaks for EV purchases. While these incentives played a crucial role in driving early adoption, their reduction has made EVs less financially attractive for some consumers, with many U.K. buyers citing higher prices even after discounts.
  • End of ICE Ban Support: Public support for phasing out gasoline and diesel-powered cars by 2035, a key European Union policy, appears to be waning in some areas. Without robust support for this measure, consumers may be less inclined to embrace the transition to electric vehicles.
  • Economic Uncertainty: Rising inflation and fears of a recession in Europe have made consumers hesitant to invest in big-ticket purchases like new cars, regardless of fuel type. This economic uncertainty is impacting both electric and conventional vehicle sales.
  • Supply Chain Constraints: Ongoing supply chain disruptions and shortages of raw materials like lithium continue to impact the availability of affordable electric vehicles. This means potential buyers face long wait times or inflated prices even when they're ready to embrace EVs.

 

Consequences for Europe's Green Agenda

The decline in EV sales threatens Europe's plans to reduce carbon emissions and become the first climate-neutral continent by 2050, aligning with a broader push for electricity to address the climate dilemma across Europe. The transportation sector is a major contributor to greenhouse gas emissions, and the rapid electrification of vehicles is a pillar of Europe's decarbonization strategy.

The current slump highlights the need for continued policy support for the EV market, as EVs still trail gas models in many markets today, to ensure long-term growth and affordability for consumers. Without action, experts fear that Europe may find itself locked into a dependence on fossil fuels for decades to come, making its climate targets unreachable.

 

A Global Concern

Europe is a leader in electric vehicle policies and technology, during a period when global EV sales climbed markedly. The recent slowdown, however, sends a worrying signal to other regions around the world aiming to accelerate their transition to electric vehicles, including the U.S. market's Q1 dip as a cautionary example. It underscores the importance of sustained government support, investment in charging infrastructure and overcoming supply chain challenges to secure a future of widespread electric vehicle use, with many forecasts suggesting mass adoption within a decade if support continues.

Medicine Hat Grant Winners to Upgrade Grid and Use AI for Energy Savings

Medicine Hat Smart Grid AI modernizes electricity distribution with automation, sensors, and demand response, enhancing energy efficiency and renewable integration while using predictive analytics and real-time data to reduce consumption and optimize grid operations.

 

Key Points

An initiative using smart grid tech and AI to optimize energy use, cut waste, and improve renewable integration.

✅ Predictive analytics forecast demand to balance load and prevent outages.

✅ Automation, sensors, and meters enable dynamic, resilient distribution.

✅ Integrates solar and wind with demand response to cut emissions.

 

The city of Medicine Hat, Alberta, is taking bold steps toward enhancing its energy infrastructure and reducing electricity consumption with the help of innovative technology. Recently, several grant winners have been selected to improve the city's electricity grid distribution and leverage artificial intelligence (AI) to adapt to electricity demands while optimizing energy use. These projects promise to not only streamline energy delivery but also contribute to more sustainable practices by reducing energy waste.

Advancing the Electricity Grid

Medicine Hat’s electricity grid is undergoing a significant transformation, thanks to a new set of initiatives funded by government grants that advance a smarter electricity infrastructure vision for the region. The city has long been known for its commitment to sustainable energy practices, and these new projects are part of that legacy. The winners of the grants aim to modernize the city’s electricity grid to make it more resilient, efficient, and adaptable to the changing demands of the future, aligning with macrogrid strategies adopted nationally.

At the core of these upgrades is the integration of smart grid technologies. A smart grid is a more advanced version of the traditional power grid, incorporating digital communications and real-time data to optimize the delivery and use of electricity. By connecting sensors, meters, and control systems across the grid, along with the integration of AI data centers where appropriate, the grid can detect and respond to changes in demand, adjust to faults or outages, and even integrate renewable energy sources more efficiently.

One of the key aspects of the grant-funded projects involves automating the grid. Automation allows for the dynamic adjustment of power distribution in response to changes in demand or supply, reducing the risk of blackouts or inefficiencies. For instance, if an area of the city experiences a surge in energy use, the grid can automatically reroute power from less-used areas or adjust the distribution to avoid overloading circuits. This kind of dynamic response is crucial for maintaining a stable and reliable electricity supply.

Moreover, the enhanced grid will be able to better incorporate renewable energy sources such as solar and wind power, reflecting British Columbia's clean-energy shift as well, which are increasingly important in Alberta’s energy mix. By utilizing a more flexible and responsive grid, Medicine Hat can make the most of renewable energy when it is available, reducing reliance on non-renewable sources.

Using AI to Reduce Energy Consumption

While improving the grid infrastructure is an essential first step, the real innovation comes in the form of using artificial intelligence (AI) to reduce energy consumption. Several of the grant winners are focused on developing AI-driven solutions that can predict energy demand patterns, optimize energy use in real-time, and encourage consumers to reduce unnecessary energy consumption.

AI can be used to analyze vast amounts of data from across the electricity grid, such as weather forecasts, historical energy usage, and real-time consumption data. This analysis can then be used to make predictions about future energy needs. For example, AI can predict when the demand for electricity will peak, allowing the grid operators to adjust supply ahead of time, ensuring a more efficient distribution of power. By predicting high-demand periods, AI can also assist in optimizing the use of renewable energy sources, ensuring that solar and wind power are utilized when they are most abundant.

In addition to grid management, AI can help consumers save energy by making smarter decisions about how and when to use electricity. For instance, AI-powered smart home devices can learn household routines and adjust heating, cooling, and appliance usage to reduce energy consumption without compromising comfort. By using data to optimize energy use, these technologies not only reduce costs for consumers but also decrease overall demand on the grid, leading to a more sustainable energy system.

The AI initiatives are also expected to assist businesses in reducing their carbon footprints. By using AI to monitor and optimize energy use, industrial and commercial enterprises can cut down on waste and reduce energy-related operational costs, while anticipating digital load growth signaled by an Alberta data centre agreement in the province. This has the potential to make Medicine Hat a more energy-efficient city, benefiting both residents and businesses alike.

A Sustainable Future

The integration of smart grid technology and AI-driven solutions is positioning Medicine Hat as a leader in sustainable energy practices. The city’s approach is focused not only on improving energy efficiency and reducing waste but also on making electricity consumption more manageable and adaptable in a rapidly changing world. These innovations are a crucial part of Medicine Hat's long-term strategy to reduce carbon emissions and meet climate goals while ensuring reliable and affordable energy for its residents.

In addition to the immediate benefits of these projects, the broader impact is likely to influence other municipalities across Canada, including insights from Toronto's electricity planning for rapid growth, and beyond. As the technology matures and proves successful, it could set a benchmark for other cities looking to modernize their energy grids and adopt sustainable, AI-driven solutions.

By investing in these forward-thinking technologies, Medicine Hat is not only future-proofing its energy infrastructure but also taking decisive steps toward a greener, more energy-efficient future. The collaboration between local government, technology providers, and the community marks a significant milestone in the city’s commitment to innovation and sustainability.

Canada's looming power problem is massive but not insurmountable: report

Canada Net-Zero Electricity Buildout will double or triple power capacity, scaling clean energy, renewables, nuclear, hydro, and grid transmission, with faster permitting, Indigenous consultation, and trillions in investment to meet 2035 non-emitting regulations.

 

Key Points

A national plan to rapidly expand clean, non-emitting power and grid capacity to enable a net-zero economy by 2050.

✅ Double to triple generation; all sources non-emitting by 2035

✅ Accelerate permitting, transmission, and Indigenous partnerships

✅ Trillions in investment; cross-jurisdictional coordination

 

Canada must build more electricity generation in the next 25 years than it has over the last century in order to support a net-zero emissions economy by 2050, says a new report from the Public Policy Forum.

Reducing our reliance on fossil fuels and shifting to emissions-free electricity, as provinces such as Ontario pursue new wind and solar to ease a supply crunch, to propel our cars, heat our homes and run our factories will require doubling — possibly tripling — the amount of power we make now, the federal government estimates.

"Imagine every dam, turbine, nuclear plant and solar panel across Canada and then picture a couple more next to them," said the report, which will be published Wednesday.

It's going to cost a lot, and in Ontario, greening the grid could cost $400 billion according to one report. Most estimates are in the trillions.

It's also going to require the kind of cross-jurisdictional co-operation, with lessons from Europe's power crisis underscoring the stakes, Indigenous consultation and swift decision-making and construction that Canada just isn't very good at, the report said.

"We have a date with destiny," said Edward Greenspon, president of the Public Policy Forum. "We need to build, build, build. We're way behind where we need to be and we don't have a lot of a lot of time remaining."

Later this summer, Environment Minister Steven Guilbeault will publish new regulations to require that all power be generated from non-emitting sources by 2035 clean electricity goals, as proposed.

Greenspon said that means there are two major challenges ahead: massively expanding how much power we make and making all of it clean, even though some natural gas generation will be permitted under federal rules.

On average, it takes more than four years just to get a new electricity generating project approved by Ottawa, and more than three years for new transmission lines.

That's before a single shovel touches any dirt.

Building these facilities is another thing, and provinces such as Ontario face looming electricity shortfalls as projects drag on. The Site C dam in British Columbia won't come on line until 2025 and has been under construction since 2015. A new transmission line from northern Manitoba to the south took more than 11 years from the first proposal to operation.

"We need to move very quickly, and probably with a different approach ... no hurdles, no timeouts," Greenspon said.

There are significant unanswered questions about the new power mix, and the pace at which Canada moves away from fossil fuel power is one of the biggest political issues facing the country, with debates over whether scrapping coal-fired electricity is cost-effective still unresolved.
